Drug-induced androgenic alopecia

This code describes hair loss from the scalp, specifically androgenic alopecia, that is a direct adverse effect of a prescribed or illicit drug. It signifies a pattern of hair thinning or baldness characteristic of androgenic alopecia, but with a clear pharmacological etiology.

Use this code when documentation explicitly links androgenic alopecia to a medication. This typically involves a patient presenting with hair loss that began or worsened after starting a new drug, and the clinician has identified the drug as the causative agent. Documentation should include the specific drug implicated.

• Always code the adverse effect of the drug first (T36-T50 with 5th or 6th character indicating adverse effect), followed by this code.
• Ensure the documentation clearly states "drug-induced" and specifies androgenic alopecia, not just general alopecia.
• Do not use this code for non-drug-induced androgenic alopecia (L64.x) or other forms of drug-induced alopecia (L65.8).
