M21.529

Billable

Acquired clubhand, unspecified hand

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

What This Code Means

A deformity where the hand is bent or twisted into an abnormal position resembling a club, but the specific hand (right or left) is not documented. This condition develops after birth due to injury, disease, or other acquired causes.

Coding Tips

  • •Use this code only when laterality cannot be determined; attempt to obtain documentation specifying right (M21.521) or left (M21.522) hand
  • •This is a less specific code and should be avoided when possible in favor of laterality-specific codes
