Billable

Unequal limb length (acquired), right radius

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

What This Code Means

The right forearm bone (radius) is shorter than the left, causing unequal limb length acquired after birth.

Coding Tips

  • •Ensure documentation specifies the right radius and that the condition is acquired, not congenital
  • •Distinguish between radius and ulna shortening as they have different codes
