ICD-10-CM Code: T36.8X2S - Poisoning by Other Systemic Antibiotics, Intentional Self-Harm, Sequela
Category:
Injury, poisoning and certain other consequences of external causes > Injury, poisoning and certain other consequences of external causes
Description:
This code specifically targets poisoning resulting from deliberate self-harm involving systemic antibiotics, with a focus on the long-term effects (sequela) of the poisoning event.
Excludes:
This code is distinct from the following:
Excludes1:
Antineoplastic antibiotics (T45.1-) - This code is used for poisoning caused by chemotherapy drugs.
Locally applied antibiotic NEC (T49.0) - This code applies to poisoning from antibiotics directly applied to skin or mucous membranes.
Topically used antibiotic for ear, nose and throat (T49.6)
Topically used antibiotic for eye (T49.5)
Notes:
Parent Code Notes: T36.8X2S is a subcategory within the broader T36 code family.
Underdosing: This code can also be used for instances of taking less medication than prescribed, regardless of intention (unintentional or deliberate).
Dependencies and Related Codes:
ICD-10-CM: This code will likely be utilized alongside other ICD-10-CM codes to provide a comprehensive picture, including the type of antibiotic, symptoms of poisoning, or any accompanying medical conditions. Examples of relevant codes include: T36.0-T36.9 (Codes for poisoning by specific systemic antibiotics) F55.- (Codes for abuse of non-dependence producing substances) - This code would be appropriate when intentional misuse is involved.
External Cause Codes: ICD-10-CM guidelines necessitate additional codes from Chapter 20 (External Causes of Morbidity) to clarify the mechanism of poisoning, for instance, self-harm or accidental ingestion.
DRG Codes: This code could potentially be linked to the following DRG codes: 922: OTHER INJURY, POISONING AND TOXIC EFFECT DIAGNOSES WITH MCC 923: OTHER INJURY, POISONING AND TOXIC EFFECT DIAGNOSES WITHOUT MCC
Usage Scenarios:
Scenario 1: Intentional Overdose with Long-Term Sequela
A patient deliberately overdoses on amoxicillin, a systemic antibiotic, as a form of self-harm. Subsequent to treatment, the patient experiences persistent hearing loss.
Codes:
T36.2X2S - Poisoning by amoxicillin, intentional self-harm, sequela
H91.9 - Unspecified sensorineural hearing loss
Scenario 2: Accidental Ingestion Leading to Hospitalization
A child mistakenly consumes multiple doses of a broad-spectrum antibiotic intended for their parent. The child suffers severe liver damage, requiring prolonged hospitalization.
Codes:
T36.8X1A - Poisoning by other systemic antibiotics, accidental (unintentional) exposure, initial encounter
K72.2 - Hepatic failure, not elsewhere classified
Y92.9 - Drug and medication poisoning in the home
Scenario 3: Incorrect Dosage Leading to Adverse Effects
A patient takes an underdosage of azithromycin, a systemic antibiotic, mistakenly taking fewer tablets than prescribed. This leads to the antibiotic being ineffective and the underlying infection continuing.
Codes:
T36.8X2S - Poisoning by other systemic antibiotics, intentional self-harm, sequela (in this case, deliberate underdosing)
[Code for specific infectious disease based on clinical context, e.g., pneumonia (J18.-), UTI (N39.-) etc.]
Remember: This code description provides comprehensive information regarding ICD-10-CM code T36.8X2S. However, it is essential to consult with seasoned medical coding professionals and rely on the official ICD-10-CM guidelines for the most accurate coding guidance.
