ICD-10-CM Code: M84.41 - Pathological Fracture, Shoulder
This code represents a fracture of the shoulder bone occurring due to a pre-existing pathological condition of the bone. This condition weakens the bone structure, making it susceptible to fracture without significant trauma.
Code Details:
Code Type: ICD-10-CM Category: Diseases of the musculoskeletal system and connective tissue > Osteopathies and chondropathies Parent Code Notes:
M84.4 - Pathological fracture, shoulder: Excludes collapsed vertebra NEC (M48.5); pathological fracture in neoplastic disease (M84.5-); pathological fracture in osteoporosis (M80.-); pathological fracture in other disease (M84.6-); stress fracture (M84.3-); traumatic fracture (S12.-, S22.-, S32.-, S42.-, S52.-, S62.-, S72.-, S82.-, S92.-). M84 - Excludes traumatic fracture of bone – see fracture, by site.
Exclusions:
Excludes1: M48.5 - Collapsed vertebra, unspecified M84.5- - Pathological fracture in neoplastic disease M80.- - Pathological fracture in osteoporosis M84.6- - Pathological fracture in other disease M84.3- - Stress fracture S12.-, S22.-, S32.-, S42.-, S52.-, S62.-, S72.-, S82.-, S92.- - Traumatic fracture
Excludes2: Z87.311 - Personal history of (healed) pathological fracture
Modifier:
This code requires an additional 6th digit. The 6th digit represents the encounter type:
ICD-10-7th Character: A: Initial encounter for fracture D: Subsequent encounter for fracture with routine healing G: Subsequent encounter for fracture with delayed healing K: Subsequent encounter for fracture with nonunion P: Subsequent encounter for fracture with malunion S: Sequela
Use Case Examples:
Scenario 1: A 68-year-old female patient presents to the emergency room with severe pain in her right shoulder. She reports that she was reaching for a book on a high shelf when she felt a sharp snap. Upon examination, the physician notices significant tenderness and swelling around the right shoulder. An X-ray confirms a fracture of the right humerus. However, further examination reveals a history of osteoporosis, a condition that weakens bones and makes them more susceptible to fractures. The physician diagnoses a pathological fracture of the right humerus due to underlying osteoporosis and documents this diagnosis as M84.41A for the initial encounter.
Scenario 2: A 45-year-old male patient visits his physician with persistent pain and discomfort in his left shoulder. He reports a history of a small, slow-growing bone tumor near the shoulder joint that was previously diagnosed but had not been causing symptoms. The patient states that he experienced minimal trauma, a minor bump while walking his dog, but immediately felt a sharp pain. An X-ray confirms a fracture of the left scapula. Due to the existing bone tumor and lack of significant trauma, the physician diagnoses a pathological fracture of the left scapula related to the existing tumor and assigns code M84.41D for a subsequent encounter with routine healing.
Scenario 3: A 72-year-old patient with a history of multiple myeloma, a type of bone cancer, is admitted to the hospital with severe pain and swelling in her left shoulder. The patient denies any specific trauma, but X-rays reveal a fracture of the left clavicle. Due to the history of myeloma and the lack of a clear injury, the physician diagnoses the fracture as a pathological fracture associated with multiple myeloma and uses code M84.41K to code for a subsequent encounter with nonunion of the clavicle fracture.
Clinical Significance:
Pathological fractures of the shoulder are a serious medical concern due to their association with underlying diseases that weaken the bones.
Factors that may increase risk for pathological fracture: Osteoporosis Bone cancer Bone infections (osteomyelitis) Bone diseases like Paget’s disease
Treatment:
Treatment will depend on the severity of the fracture and the underlying disease. Common treatments include:
Non-surgical treatment: Rest, immobilization with a sling, pain medication.
Surgical treatment: Repairing the fracture with screws or plates, bone grafting.
Further Documentation:
A thorough medical history, clinical examination, and appropriate imaging studies (X-ray, CT, MRI) are crucial for the accurate diagnosis and treatment of a pathological fracture of the shoulder. The underlying cause of the pathological fracture, such as osteoporosis, bone tumor, or infection, should also be identified and coded.
