Spontaneous rupture of other tendons, unspecified forearm

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

What This Code Means

A tendon in the forearm suddenly tears or breaks on its own, but the specific side (left or right) is not documented.

Coding Tips

  • •Use this code only when laterality cannot be determined from the medical record
  • •Query the provider if possible to obtain specific laterality information for more precise coding
