Spontaneous rupture of other tendons, right thigh

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

What This Code Means

Coding Tips

  • •Distinguish between quadriceps and hamstring ruptures if documented, though both use this code
  • •Note any associated weakness or difficulty with walking or leg movement
