Bone graft failure

This code signifies the unsuccessful integration or healing of a transplanted bone tissue. It indicates that the bone graft, whether autograft, allograft, or synthetic, has failed to achieve its intended purpose of promoting bone union or regeneration. This can manifest as non-union, malunion, or resorption of the graft material.

Apply this code when documentation clearly states that a bone graft has failed, regardless of the anatomical site or the type of graft used. This includes situations where a patient presents with persistent pain, instability, or imaging evidence (e.g., X-ray, CT scan) showing lack of fusion or collapse of the graft. It is appropriate for both initial and subsequent encounters related to the failed graft.

• Always look for explicit documentation of "graft failure," "non-union of graft," or "resorption of graft."
• Do not use this code for complications of the graft (e.g., infection of graft) unless the graft itself has failed to integrate.
• Code the underlying condition requiring the bone graft (e.g., fracture nonunion) as a primary diagnosis if still relevant.
