Spontaneous rupture of other tendons, left lower leg

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

What This Code Means

A tendon in the left lower leg (calf or shin area) suddenly tears or breaks on its own without a specific injury.

Coding Tips

  • •Verify left lower leg laterality is clearly documented in the medical record
  • •Document the specific tendon affected (Achilles, tibialis, peroneal) if available for clinical clarity
