M66.38
BillableSpontaneous rupture of flexor tendons, other site
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A tendon in the hand or foot that helps bend fingers or toes suddenly tears on its own without a major injury.
Coding Tips
- •Use this code when the flexor tendon rupture occurs at a site other than the hand or foot (e.g., wrist area)
- •Verify documentation specifies the exact anatomical location to ensure this 'other site' code is appropriate rather than more specific codes
