Billable

Unequal limb length (acquired), left humerus

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

What This Code Means

The left upper arm bone (humerus) is shorter than the right, causing unequal limb length acquired after birth.

Coding Tips

  • •Ensure documentation specifies the left humerus and that the condition is acquired, not congenital
  • •Consider documenting the cause (trauma, surgery, disease) if known
