Epidermolysis bullosa due to drug

This code signifies a blistering skin disorder characterized by fragile skin and blister formation, specifically caused by an adverse reaction to a medication. The bullae result from minor trauma or friction due to the drug's effect on skin integrity.

Assign this code when documentation clearly links the patient's epidermolysis bullosa to a prescribed or illicit drug. Supporting documentation should include a detailed medication history, clinical findings of blistering, and a physician's assessment attributing the condition to the drug.

• Always code the adverse effect of the drug first, followed by the specific drug (T36-T50 with 5th or 6th character 5).
• Distinguish from other forms of epidermolysis bullosa (e.g., congenital, acquired) which have different code assignments.
• Ensure the physician's documentation explicitly states the drug as the causative agent for the epidermolysis bullosa.
