Hey, healthcare heroes! Let's talk about AI and automation in medical coding and billing, because frankly, we could all use a little help deciphering those codes, right? What's the difference between a medical code and a bad joke? A bad joke can make you groan, but a wrong medical code can cost you a lot of money!

What is the correct code for surgical procedure with general anesthesia?

General anesthesia is a type of anesthesia that causes a patient to lose consciousness. This is usually administered for surgical procedures, which require complete relaxation of the muscles and body. In this article, we will GO through the basics of medical coding and take a closer look at various modifiers used in coding medical procedures.

When choosing codes for medical procedures performed under general anesthesia, healthcare providers, and medical coders, have to look at the procedure itself and also choose the appropriate modifiers for specific services. CPT codes and modifiers are proprietary codes owned by American Medical Association. Medical coders and providers have to obtain a license and buy the latest updated code list from AMA in order to use CPT codes. Failing to do so would constitute an illegal practice of using intellectual property without proper license and could lead to very serious legal consequences, including financial penalties and potential jail time.

There is no single, universal code for all procedures done under general anesthesia. Rather, the code selected will depend on the specific type of procedure performed. This article discusses the general guidelines for choosing a procedure code and will provide information on choosing the correct modifiers for your chosen code.

Medical coding is a critical component of healthcare billing, ensuring accuracy in billing and reimbursements. Incorrect coding, especially with CPT codes, could lead to incorrect billing, financial penalties for providers and even potential legal issues. Medical coding requires consistent attention to detail and constant learning, since codes are updated frequently, requiring providers and coders to continuously be educated on latest modifications and update their practice.

Modifiers in medical coding.

Modifiers are additions to codes used in medical billing. They further specify services provided. We will discuss specific modifiers below. Here is an example of how the same surgery could be billed differently using different modifiers:

Scenario #1 - Open Reduction and Internal Fixation - Simple

John, a 58-year-old construction worker, injured his ankle during work. The doctor's assessment revealed a severe fracture in his ankle, necessitating open reduction and internal fixation, also called ORIF, procedure. After a detailed discussion with John, his physician recommended performing the procedure under general anesthesia.

John’s insurance provider will cover the surgery and his physician scheduled him for surgery on an outpatient basis, using the operating room. The provider will be the surgeon and, as HE chose general anesthesia for this procedure, a certified registered nurse anesthetist (CRNA) will also be present at the procedure to administer general anesthesia.

While John's surgery can be documented with CPT code 27830 (Open reduction and internal fixation (ORIF) of ankle fracture, percutaneous or through a small incision; simple). To accurately depict the procedure, John’s physician should add a modifier that signifies that John had an ORIF done in an outpatient facility. Modifier - 22 - represents increased procedural services. The code with modifier should be entered as: 27830-22. This modifier lets the payer know the procedure was more extensive than normally. In addition, a modifier should be used to reflect that this was an ORIF performed in an outpatient setting: 27830-22-AS.

The 1AS signifies “Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery”, since a CRNA was present during John’s ORIF.

Scenario #2 - Open Reduction and Internal Fixation - Complex

Mary, a 25-year-old fitness enthusiast, was involved in a car accident. She sustained a severe fracture in her lower right leg that was very unstable.

Mary’s orthopedist recommended ORIF. Since it was a more complex fracture, and considering her age, the surgeon performed it under general anesthesia.

In Mary’s case, we can bill the code for Open reduction and internal fixation (ORIF) of fracture of the shaft of tibia and fibula, percutaneous or through a small incision, and external fixation of fracture of shaft of tibia and fibula; with significant soft tissue injury or bone loss; with or without flap procedures or significant contamination. This code would be: 27765.

Because it was a complex procedure and was done in an outpatient facility under general anesthesia, two modifiers are needed to accurately reflect Mary’s case:

27765-22-AS

In Mary's case, the 22 modifier - Increased Procedural Services, which will indicate that the surgery was a more complex procedure than a simple fracture requiring open reduction.

We also should add the AS modifier signifying “Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery”, because a CRNA was involved in Mary’s procedure.

Scenario #3 - Open Reduction and Internal Fixation of Wrist

George, a 60-year-old mechanic, suffered a fall during work. His visit to his physician revealed HE has a fracture in his wrist, which requires surgery. He was a heavy smoker and the doctor determined HE has to undergo a surgical procedure for his fractured wrist under general anesthesia.

George’s surgeon opted to do an Open reduction and internal fixation (ORIF) of wrist, for which the CPT code is 27246.

To bill for this procedure done under general anesthesia and as a staged procedure in an outpatient setting, we should use the modifier 58 - Staged or Related Procedure or Service by the Same Physician or Other Qualified Health Care Professional During the Postoperative Period. It is also necessary to add the AS modifier to account for a certified registered nurse anesthetist who assisted with general anesthesia.

27246-58-AS

Other Modifiers used in Medical Coding

Modifiers in medical coding are extremely helpful to illustrate the complexity of the procedure, and the location where the service was delivered, if necessary. The table below illustrates the full list of modifiers which can be used to further define medical procedures. This is not a full list of all CPT modifiers and the coder should use only the updated, current CPT code list to have access to all codes and modifiers currently available. It’s always important to check the current code set for updated information.

Modifier - 22

Increased Procedural Services

Description: Modifier 22 - increased procedural services, signifies that the procedure being performed is more complex than usual. For instance, a complex ORIF procedure can be coded as 27765 - 22, compared to a standard ORIF of an ankle coded as 27830 - 22.

Modifier - 51

Multiple Procedures

Description: This modifier (51) - multiple procedures - means a healthcare provider performed two or more distinct, non-bundled surgical procedures. The modifier 51 will help the coder reduce the reimbursement for the two procedures because performing more than one procedure is a bit more efficient and quicker, therefore reducing the total time and resources required.

Use Case

Susan, a 30-year-old, had to undergo two separate, distinct surgical procedures. While Susan's physician typically performs these procedures separately, in her case, both could be performed simultaneously during the same surgery session. As a medical coder, in order to appropriately code this procedure, we would include modifier 51 to represent the bundled procedure, which will reduce the total payment by 15% from the value of both separate procedures. The provider is typically responsible to perform the procedures and explain the modifier 51 use in Susan’s billing documentation.

Modifier - 52

Reduced Services

Description: Modifier - 52 - Reduced Services is typically used when the surgeon performing the procedure performed less service than usual or the service performed was reduced due to an unforeseen medical circumstance.

Use Case

John, a 33-year old patient, was supposed to have surgery for a spinal fusion. This is a lengthy and complex procedure. The patient’s doctor determined John’s health deteriorated, and therefore, it would be too risky to proceed with the complex spine fusion surgery.

John’s surgeon decided to perform a minimally invasive procedure, resulting in reduced surgery time. As a coder, we should include modifier 52 in this case to reflect that the service was reduced by the provider due to the medical situation, with full documentation present in John’s patient record.

Modifier - 53

Discontinued Procedure

Description: This modifier (53) - Discontinued Procedure - signifies that the procedure performed was discontinued because a provider encountered unforeseen circumstances, such as a patient experiencing a medical emergency. In the instance of a discontinued procedure, the coder is required to bill the portion of the procedure which was completed, reflecting only the performed service, but not the portion which was discontinued.

Use Case

Michael, a 65-year-old, was scheduled for laparoscopic hernia repair, which is a minimally invasive procedure to repair an inguinal hernia. In this case, an inguinal hernia is located in the groin area, and it’s a common issue affecting men more than women. The code used to document this laparoscopic hernia repair would be: 49505.

During the procedure, Michael’s surgeon noticed his patient experienced a cardiac arrest. Due to the severity of the medical emergency, Michael’s surgeon, following his best medical practice, discontinued the procedure immediately and focused on Michael’s medical emergency. Michael had a few days of care in an intensive care unit and, eventually, recovered from his episode of cardiac arrest. Michael’s physician was able to stabilize him and later decided to reschedule Michael’s procedure after a thorough recovery.

In this case, the coding professional would bill 49505-53, signifying that Michael’s surgeon performed a part of the procedure (a portion of 49505 - laparoscopic hernia repair), but it was discontinued due to a medical emergency. In this specific case, no full payment should be provided by the insurer.

Modifier - 54

Surgical Care Only

Description: Modifier - 54 - Surgical Care Only is an important modifier used for the portion of the medical billing which addresses the surgery and procedures only. In cases where surgical care only is billed, no additional services like pre- or post- operative care are provided and only the service during the surgery, the “Surgical Care” only should be billed.

Use Case

Mary was admitted to the hospital to undergo surgery for her fractured hip.

Mary’s surgeon scheduled Mary for open reduction and internal fixation of fracture of the hip, with the CPT code 27254, performed on an inpatient basis. During Mary’s surgery, she only required surgical care. Pre-operative and postoperative care was not provided by the same provider who did the surgical care. In this case, Mary’s surgeon provided her care during the surgical portion of the procedure and her primary care physician was responsible for post-operative and pre-operative care. This type of situation could arise if a patient required specific expertise in a procedure from a specialist, for instance, the surgical intervention in Mary’s case was a complex surgical procedure and the patient’s primary care provider felt confident in performing only the initial evaluation, consultation and any needed follow-ups.

Since her surgery was performed by her surgeon and post-operative care provided by a different provider, it's vital to code her surgery appropriately, utilizing the 54 modifier: 27254-54. Modifier 54 ensures proper payment is generated for surgical care, without providing compensation for the portions of the service rendered by her primary care provider.

Modifier - 55

Postoperative Management Only

Description: This modifier is used only in cases when a provider is only involved in the post-operative portion of care. When coding a procedure for post-operative management, only, the provider should utilize modifier 55, which will show that a particular provider was responsible for postoperative management only.

Use Case

Mary's doctor referred her to a specialist, who was not the one to perform her hip replacement procedure, but who had specialized expertise in follow-up care. Mary’s physician wanted to make sure the postoperative recovery was managed by someone with high expertise in recovery management, due to potential risk of complications for hip replacements.

After the surgery was performed by a general surgeon, the patient had a specialist providing her care during the recovery. Mary’s recovery was carefully followed up, to ensure minimal risk of any issues and to monitor her recovery process. As Mary’s hip replacement was already performed by another physician, the provider seeing Mary should code the post-operative care procedure, with the modifier 55 - Postoperative Management Only.

Modifier - 56

Preoperative Management Only

Description: The provider utilizing this modifier provides only pre-operative management to a patient. Pre-operative management involves medical interventions preceding the surgery, to prepare a patient for surgery. In many instances, the primary care physician handles pre-operative care and prepares a patient for surgery, for instance by assessing medical history, ordering laboratory tests, pre-surgery check-up, educating on pre-surgery care protocols and any other preparations necessary before the surgery takes place.

Use Case

Sarah, a 70-year-old patient with diabetes and high blood pressure, is planning a surgery to treat a fractured tibia, an extremely common problem in elderly patients who experience osteoporosis. This is considered a standard, straight-forward fracture repair, and does not need a specific surgeon. The surgery will be done on an outpatient basis, after Sarah meets with her primary care provider for pre-operative assessment. Since her medical history involves conditions requiring particular attention and preparation prior to any surgical procedure, Sarah's physician, as her primary care provider, orders required pre-operative tests, medications and gives her specific instructions prior to her upcoming surgical procedure. She had surgery and her surgeon performed 27746- Open reduction and internal fixation (ORIF) of fracture of the shaft of tibia, percutaneous or through a small incision; without external fixation and 27747 - Open reduction and internal fixation (ORIF) of fracture of the shaft of tibia, percutaneous or through a small incision; with external fixation. Since both of these codes represent an Open reduction and internal fixation of the tibia, they would also need to be adjusted to reflect the outpatient setting: 27746-22 and 27747-22.

In order to correctly bill Sarah’s pre-operative care, the doctor must add modifier 56 for pre-operative management only. Since the doctor already coded the procedure using CPT codes: 27746-22 and 27747-22, the doctor would then add a modifier 56, in this instance the CPT code for pre-operative management is: 99213, which is for a level 3 office visit: 99213-56.

Modifier - 58

Staged or Related Procedure or Service by the Same Physician or Other Qualified Health Care Professional During the Postoperative Period

Description: This modifier signifies a procedure that is a follow-up, or continuation, of a previous surgical procedure. This typically happens in cases requiring staged procedures where multiple operations are needed to reach the desired outcome of treatment, but all the stages of the procedure are considered related. When using modifier 58, it’s important that all stages of the surgical procedure were performed by the same physician or a qualified healthcare provider.

Use Case

Brian was experiencing significant pain and difficulties walking due to arthritis in his knee, a degenerative condition which involves the breakdown of cartilage. His physician diagnosed him with stage IV osteoarthritis and recommended a complete knee replacement to reduce pain and improve mobility. Since it was a complex procedure and it’s also a high-risk procedure, the surgeon chose to perform a total knee arthroplasty (TKA), in stages. The provider performs 27447, which represents total knee arthroplasty, which was divided into stages. Stage 1 of the procedure was completed in the operating room on an outpatient basis, with general anesthesia, with the CPT code: 27447 - 58 - AS (this is the first stage, coded as a staged procedure). The subsequent stage 2 of this procedure, coded using the CPT code 27447 - 58- AS, was performed six weeks later and it included a complex repair of the ligament that had been torn, which was necessary for the healing of Brian’s knee.

Modifier - 62

Two Surgeons

Description: Modifier 62 indicates that the service provided involved more than one surgeon, in particular, two surgeons performing a surgery simultaneously on the patient. In many instances, one surgeon may serve as the primary surgeon, while another surgeon acts as the assistant surgeon. In many circumstances, the assistant surgeon typically provides support to the primary surgeon, which might involve retracting tissues, handling instruments, closing incisions, or providing overall support to the primary surgeon. In cases when there is more than one surgeon, modifier 62 should be used to accurately reflect that two separate physicians or qualified health professionals are providing surgical care.

Use Case

John suffered a devastating car accident and needed emergency surgery for a fractured pelvis, coded 27320 - 22. He had a fractured pelvis requiring urgent surgical intervention for repair. To perform such complex procedures, often multiple surgeons are involved. Due to the complexity of the repair procedure and given the severity of John’s injury, his physicians, as surgeons, decided to work together on his surgery. One physician was acting as the main surgeon, while another surgeon was assisting, retracting tissues, managing instruments and providing all the necessary support for the primary surgeon. In such instances, in order to accurately reflect that both surgeons performed this surgery, the modifier 62 - Two Surgeons should be used, along with the main surgery code: 27320-22-62

Modifier - 76

Repeat Procedure or Service by Same Physician or Other Qualified Health Care Professional

Description: Modifier 76 signifies that the provider performed a repeat of a previous procedure they did on a patient. Repeat procedures can happen in a variety of instances. One example is if the same provider who performed the surgery was called to treat a complication after the patient’s surgical procedure. For instance, the provider might encounter a situation in which, despite being completely healed, the patient experienced a re-rupture of the tendon which had previously been surgically repaired. This is a prime example of when modifier 76 is required. This modifier signifies that the provider performed the same procedure before, and is also performing it now, when treating the post-surgical complications.

Use Case

John underwent a shoulder repair. After his surgical repair of the tendon in his shoulder, it unfortunately, re-ruptured after a few weeks. When HE visited the same doctor for this re-ruptured shoulder tendon, HE required an open repair of the tendon in the shoulder again. As this surgery is a repeat procedure, performed by the same physician, the coder will utilize modifier 76. This allows US to bill accurately, since the provider performed the same procedure again for the same patient. In this specific instance, the appropriate CPT code is 23430 (Open repair, rotator cuff; any method [eg, arthroscopic, mini-open, or open]) and modifier 76: 23430-76.

Modifier - 77

Repeat Procedure by Another Physician or Other Qualified Health Care Professional

Description: When a provider has to repeat a previously performed procedure on the patient but it is performed by a different provider, the modifier 77 should be applied to the billing. For instance, in a rare instance where a physician does not have adequate credentials for the second procedure to perform a repeat, HE or she can refer the patient to a colleague for the repeat procedure. If that procedure has to be repeated by another provider, modifier 77 is used for billing.

Use Case

Emily sustained a terrible accident that resulted in a complex leg injury requiring emergency surgery. Emily had to undergo an emergency surgery for her fractured femur in which the surgeon 27206 - 22 used a specialized plating system that required specific experience and training, which the treating surgeon, while a qualified general surgeon, lacked. For the best recovery, HE had to refer Emily to an orthopedic surgeon who was an expert in that particular plating system.

The new orthopedic surgeon examined Emily and had to repeat the original procedure 27206 - 22, which required applying a special type of plating. Due to this, the code would have modifier 77 added. Emily’s medical billing would look like this: 27206-22-77.

Modifier - 78

Unplanned Return to the Operating/Procedure Room by the Same Physician or Other Qualified Health Care Professional Following Initial Procedure for a Related Procedure During the Postoperative Period

Description: This modifier reflects an instance where a provider, who performed an initial procedure, has to GO back into the operating room to perform a follow-up or a related procedure because of a post-surgical complication. This type of event can occur after an initial surgical procedure, when an unforeseen situation demands another related surgical procedure for correction. Modifier 78 reflects the circumstances of the procedure and ensures correct billing.

Use Case

Peter, a 45-year-old, went through a laparoscopic procedure to address a large incisional hernia that HE experienced after a previous open procedure. The surgical repair was completed, and Peter was given discharge instructions for post-surgical care, but unfortunately, several days later, his physician encountered an unforeseen situation that needed additional surgery.

Peter returned to his physician a few days later due to the worsening symptoms and increased pain. He was experiencing discomfort and had swelling that started after his initial surgery, while recovering at home. His physician recommended an immediate surgery to address the situation. Since Peter’s physician performed his initial surgery, and his return to surgery was for a related complication following a previous surgery, HE should code it with the code: 49581, as the provider performing the surgical repair for incisional hernia with a modifier 78: 49581-78.

Modifier - 79

Unrelated Procedure or Service by the Same Physician or Other Qualified Health Care Professional During the Postoperative Period

Description: This modifier is used for procedures performed in the operating room during the postoperative period by the provider who initially performed the original procedure, however, the new procedure is unrelated to the initial procedure performed previously. In many instances, providers may have patients scheduled for elective surgery, and later, need to treat emergent conditions for the same patient. Modifier 79 can be applied in cases where a provider had a patient for initial surgery, who may be experiencing complications or require further surgical intervention, but these instances are unrelated to the initial procedure performed by the provider.

Use Case

Carol is 48-year-old and underwent a surgical procedure to remove her appendix. She recovered and was discharged home. However, when she returned to her physician for post-operative check up, she complained of intense abdominal pain in the left lower abdomen. Carol’s physician suspected it was diverticulitis, a condition often experienced in adulthood that often leads to emergency surgery. It is completely unrelated to the appendectomy performed earlier. As a result, the provider immediately admitted Carol to the hospital for surgical repair of the diverticulitis. This case is relevant to modifier 79, as the provider performed the previous appendectomy for Carol, but the current surgery to correct her diverticulitis is unrelated to the initial appendectomy performed on her. Since Carol’s provider did both procedures, a modifier 79 would be added to 44200 - 22 (Removal of diverticulum; colon): 44200 - 22- 79.

Modifier - 80

Assistant Surgeon

Description: Modifier 80 is used for billing in cases where the procedure requires an assistant surgeon who works under the supervision of the main surgeon. Modifier 80 will also cover the assistant surgeon’s payment for the services performed during the surgical procedure.

Use Case

Emily’s hip replacement required a second surgeon. Emily's surgeon is performing a total hip replacement surgery on her and the procedure requires additional assistance in retracting tissues, assisting with managing instruments and overseeing the whole surgical process, including suture ligation. In order to bill accurately, the physician who is assisting with the procedure, will bill modifier 80 - Assistant Surgeon for this complex procedure: 27130 - 80. In this case, the main surgeon will also bill 27130 - 22, with the 22 modifier - increased procedural services - as the primary surgeon. The provider has to make sure to document the presence of the assistant surgeon and the level of participation in the procedure, as required for accurate billing and to ensure that the assistant surgeon receives payment.

Modifier - 81

Minimum Assistant Surgeon

Description: This modifier indicates that the provider performed the service as the minimum assistant surgeon during a procedure performed by the main surgeon.

Use Case

Peter is an ophthalmologist and recently operated on a patient’s cataract. For his patient’s case, Peter’s work included performing procedures that are usually provided by an assistant surgeon. Due to the patient's conditions, HE felt more confident performing it himself to provide a specific level of precision during the surgical process. This may involve a combination of retracting tissues, managing instruments and a high level of engagement in assisting the primary surgeon. Because HE provided assistance as the minimum assistant surgeon in this instance, HE would bill it using modifier 81 - Minimum Assistant Surgeon along with his primary surgery code 66984.

Modifier - 82

Assistant Surgeon (when qualified resident surgeon not available)

Description: When an assistant surgeon assists the main surgeon with the procedure but a resident surgeon is not available, the modifier 82 would be added. In such a case, it's essential to ensure a qualified assistant surgeon is present. If a qualified assistant surgeon is present but a resident surgeon is unavailable, the coder should make sure to indicate it, adding modifier 82 in the bill.

Use Case

A surgeon performs a total hip replacement. 27130 in this instance, and an assistant surgeon was assisting him during the surgical procedure. However, the resident surgeon is on a conference out of state, therefore, the resident was not available to assist with this surgical procedure. As a result, it’s essential to include the 82 - Assistant Surgeon modifier in this particular instance. The provider should document it in the chart to accurately bill for the assistant surgeon’s services with the proper modifier.

Modifier - 99

Multiple Modifiers

Description: This modifier should be used only in cases where the billing requires multiple modifiers, as outlined in the list.

Use Case

A patient has to undergo a major surgical procedure that requires additional assistance, for example, a second surgeon and a qualified registered nurse anesthetist to provide general anesthesia. In these cases, multiple modifiers need to be applied: modifier 62 - two surgeons - and modifier AS - for the certified registered nurse anesthetist who administered the anesthesia. For instance, a surgery requiring open reduction and internal fixation, or ORIF, performed by two surgeons, with general anesthesia can be coded: 27830 - 22 - 62- AS, with the AS modifier added for the certified registered nurse anesthetist.

Since this scenario utilizes more than one modifier, 99 is used - Multiple Modifiers - which ensures proper compensation for the provider, considering all the multiple modifiers applied. This would allow for the surgeon, the assistant surgeon, the registered nurse anesthetist and any other healthcare professional involved to get reimbursed for their participation in this major, complex procedure.

Modifier - AQ

Physician providing a service in an unlisted health professional shortage area (hpsa)

Description: Modifier AQ should be used to indicate that a physician is providing services in an underserved area, also known as a health professional shortage area (hpsa). These are regions with inadequate medical professionals compared to the local need. When this modifier is used for billing, there is a chance for a slight increase in payment, compared to the standard reimbursement. It’s vital that the provider ensures HE or she meets the eligibility requirements to be considered for increased compensation for providing medical services in an underserved area.

Use Case

Carol’s surgeon operated on her knee, however, HE performs surgeries in a health professional shortage area. As a provider working in a health professional shortage area (hpsa), Carol's physician is eligible to receive increased reimbursement. His billing for the services should include modifier AQ - Physician providing a service in an unlisted health professional shortage area (hpsa). It’s critical to note, not all medical providers are eligible to be reimbursed with an increased payment.

Modifier - AR

Physician provider services in a physician scarcity area

Description: This modifier is utilized when a physician provides services in an area designated as a physician scarcity area. The provider would include modifier AR - Physician provider services in a physician scarcity area along with the main CPT code for the provided service, if the provider is located in an area deemed as a physician scarcity area. This modifier can result in a potential increase in reimbursement, compared to the standard rate.

Use Case

Richard performed open heart surgery, which is coded as 33900 - 22 - AS - increased procedural service, requiring assistant surgeon (general anesthesia provided by a registered nurse anesthetist), at a hospital located in a rural area where access to medical care and physicians is scarce, hence a physician scarcity area. As a physician, Richard’s billing should also include modifier AR - Physician provider services in a physician scarcity area. Richard is eligible for additional reimbursement due to his position in a designated area lacking an adequate number of medical providers, while facing a large number of individuals who need medical care.

Modifier - AS

Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery

Description: When an assistant at surgery (such as a certified registered nurse anesthetist (CRNA) or a physician assistant) participates in a surgical procedure and is not the primary surgeon, this modifier - AS - is used to indicate that an additional provider contributed to the services, but not as the main surgeon.

Use Case

A physician performed a laparoscopic hernia repair. The physician also required a physician assistant for this procedure to monitor the patient and keep the surgical room sterile. To bill this appropriately, the provider should include AS - Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery modifier, which should be added to the code for laparoscopic hernia repair: 49505 - 22 - AS.

Modifier - CR

Catastrophe/disaster related

Description: This modifier CR - Catastrophe/disaster related - should be added to the CPT code only in cases where the service provided by the provider is directly related to a catastrophe, such as a hurricane, flood, earthquake, and any other event officially deemed a catastrophe.

Use Case

Emily was severely injured after the tornado hit the city. She rushed to the closest emergency room to get treated for severe leg fracture and internal injuries, requiring complex procedures and surgical intervention. Her physician who treated her is a provider, eligible to get paid extra, considering HE took a catastrophic/disaster event. Since Emily was hurt during a natural disaster and needed immediate medical care, her medical billing will include a modifier CR - Catastrophe/disaster related, along with 27746 - 22 (Open reduction and internal fixation (ORIF) of fracture of the shaft of tibia, percutaneous or through a small incision; without external fixation) - an open reduction and internal fixation, or ORIF, procedure performed after a natural disaster, coded: 27746-22-CR. This modifier helps to ensure proper reimbursement to the providers who provide essential medical services during a catastrophe.

Modifier - ET

Emergency services

Description: This modifier ET - Emergency Services is used when a provider is called for an emergency visit, usually after hours, on the weekends or during holidays, to provide emergency care.

Use Case

Michael is experiencing excruciating back pain, that seems to worsen after his previous workout routine. He tries to reach his physician on a Saturday, however, the doctor is unavailable to answer the call. Michael continues experiencing unbearable pain. In this instance, Michael reached out to his primary care provider and HE was available to address this emergent medical need, which, according to his best medical practice, qualified as an emergency. Since it was an urgent situation outside of standard operating hours, Michael’s primary care provider was able to perform the visit and, given this urgent need for care, Michael’s billing will reflect that this service was an emergency visit. As a result, it would include modifier ET - Emergency Services . Michael’s visit is also coded: 99281- ET - level 3 office visit during a time frame outside the standard clinic schedule. This modification allows providers to charge appropriately when they are called to perform emergency visits during their off-schedule time, while responding to urgent medical need.
