Billable

Spontaneous rupture of flexor tendons, multiple sites

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

What This Code Means

Multiple tendons that help bend fingers or toes spontaneously tear in different locations without a major injury.

Coding Tips

  • •This code indicates ruptures affecting more than one site; document all affected locations in the medical record
  • •Consider if bilateral involvement exists and whether separate codes for each side would be more appropriate
