Billable

Flexion deformity, unspecified knee

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

What This Code Means

A permanent bending or curling of the knee joint where the specific side (left or right) is not identified in the documentation.

Coding Tips

  • •Attempt to clarify laterality with the provider before finalizing coding
  • •If both knees are affected, use both M21.261 and M21.262 rather than the unspecified code
