Spontaneous rupture of extensor tendons, unspecified lower leg

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

What This Code Means

A sudden, unexpected tearing of the extensor tendons in the lower leg when the specific side (left or right) is not documented or is bilateral.

Coding Tips

  • •Use this code only when laterality cannot be determined from documentation
  • •If documentation specifies right or left, use M66.261 or M66.262 instead for greater specificity
