What This Code Means

A fracture of the radius or ulna (forearm bones) that occurs after surgical placement of an orthopedic implant, prosthesis, or bone plate, with the specific arm not identified.

Coding Tips

•This code is used when the laterality (left/right arm) is not documented; if documented, use M96.631 (right) or M96.632 (left) instead
•Verify that the fracture occurred as a complication following the orthopedic procedure, not as the original injury being treated

Clinical Significance

Radius or ulna fracture following orthopedic implant insertion in unspecified arm represents a serious postoperative complication requiring specialized orthopedic management. This diagnosis significantly impacts risk adjustment modeling due to complex care needs, potential revision procedures, and functional limitations affecting upper extremity use.

Documentation Requirements

✓Documentation of prior orthopedic implant, prosthesis, or bone plate insertion
✓Confirmation of radius or ulna fracture occurring after implant procedure
✓Clinical evidence establishing relationship between implant and fracture
✓Treatment plan addressing both fracture management and implant evaluation
✓Assessment of implant integrity and revision surgery considerations
✓Documentation excluding external traumatic causes for fracture
✓Provider statement confirming complication relationship to prior procedure
✓Functional assessment and rehabilitation planning documentation
