Drug-induced gout, right ankle and foot

This code signifies an inflammatory arthritis of the right ankle and foot caused by a medication. It specifically identifies gout that has been triggered or exacerbated by a drug.

Use this code when documentation clearly indicates gout affecting the right ankle and/or foot, and a specific drug is identified as the causative agent. This typically requires physician documentation linking the medication to the onset or flare of gout symptoms.

• Always identify the specific drug causing the gout with an additional external cause code (T36-T50 with 5th or 6th character indicating adverse effect).
• Ensure laterality is clearly documented as "right ankle and foot" to support this specific code.
• Distinguish from primary gout (M10.0-) or gout due to renal impairment (M10.3-) which are not drug-induced.
