Spontaneous rupture of flexor tendons, unspecified upper arm

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

What This Code Means

The flexor tendons in the upper arm spontaneously tear or rupture, but the specific side (left or right) is not documented or specified.

Coding Tips

  • •Query the provider for laterality documentation to assign a more specific code when possible
  • •Use only when bilateral involvement is documented or when side cannot be determined
