ICD-10 Codes for Foot & Ankle

A curated quick-reference of the diagnosis codes podiatry clinics reach for most. Search by code or keyword, or filter by category.

Quick reference only — not a billing authority. ICD-10-CM updates every October. Always verify the full code, laterality, and 7th character against the current CMS tabular list before billing. When in doubt, your coder or biller wins.

Tips for cleaner claims

Laterality matters. Most foot/ankle codes have right/left/unspecified variants — unspecified codes are a common (and avoidable) denial trigger. Pair diabetes codes correctly: a diabetic foot ulcer is coded with both the diabetes-with-ulcer code and the ulcer code, per the guidelines. Don't code symptoms alone when a definitive diagnosis is documented — "foot pain" (M79.67-) supports medical necessity poorly compared to the underlying condition.
