What This Code Means

A broken upper arm bone (humerus) on the right side that occurs as a complication after surgical implants, joint replacements, or bone plates were inserted.

Coding Tips

•Specify the right arm with this code; use M96.622 for left arm and M96.629 for unspecified
•Document the original implant/prosthesis and the mechanism of the new fracture

Clinical Significance

This diagnosis represents a serious postoperative complication where the right humerus fractures following orthopedic implant insertion, indicating complex medical management needs. The condition significantly impacts risk adjustment due to the need for revision surgery, extended care, and potential functional limitations.

Documentation Requirements

✓Clear documentation of prior orthopedic implant, prosthesis, or bone plate insertion
✓Confirmation of humerus fracture occurring after the implant procedure
✓Specific identification of right arm involvement
✓Temporal relationship between implant insertion and fracture occurrence
✓Current treatment plan for fracture management and implant assessment
✓Assessment of implant stability and need for revision
✓Documentation excluding traumatic causes for the fracture
✓Provider statement confirming relationship to prior orthopedic procedure
