Spontaneous rupture of flexor tendons, unspecified site

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

What This Code Means

A sudden, unexpected tearing of the flexor tendons (muscles that bend the fingers, wrist, or toes) when the specific location is not documented.

Coding Tips

  • •Attempt to identify the specific anatomical site from clinical documentation
  • •Use more specific codes (M66.31-M66.37) if the site can be determined
