Spontaneous rupture of other tendons, right 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 right forearm (other than flexor tendons) spontaneously tears without a major injury.

Coding Tips

  • •Confirm the rupture is located in the forearm region and on the right side
  • •Distinguish from upper arm (M66.82x) and hand/wrist ruptures when determining appropriate code
