Spontaneous rupture of other tendons, right upper arm

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

What This Code Means

A tendon in the right upper arm (other than flexor tendons) spontaneously tears without a major injury.

Coding Tips

  • •Confirm the rupture location is in the upper arm region and on the right side
  • •Differentiate from shoulder (M66.81x) and forearm (M66.83x) codes based on anatomical location
