Billable

Unequal limb length (acquired), right femur

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

What This Code Means

A condition where the right thighbone (femur) is shorter or longer than normal, usually caused by a previous fracture, surgery, or bone disease.

Coding Tips

  • •Confirm documentation specifies RIGHT femur and that the condition is acquired rather than congenital
  • •Document the degree of limb length discrepancy if available, as this may affect treatment planning
