M20.30

Billable

Hallux varus (acquired), unspecified foot

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A deformity where the big toe turns inward toward the other toes on an unspecified foot, typically developing over time.

Coding Tips

  • •Ensure documentation specifies this is an acquired condition, not congenital; congenital hallux varus uses different coding
  • •Use this code only when the affected foot is not specified; clarify laterality with the provider if possible
