Breakdown of int fix of bones of hand and fingers, subs

This code indicates a mechanical failure of an internal fixation device, such as a plate, screw, or pin, that was previously implanted to stabilize a fracture or perform an osteotomy in the bones of the hand or fingers. The breakdown is due to a mechanical issue with the device itself, not an infection or other biological complication. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for this complication.

Use this code when a patient presents for evaluation or treatment of a broken, bent, or otherwise mechanically compromised internal fixation device in their hand or finger bones. This applies to situations where the initial surgery has already occurred, and the patient is returning for management of the device failure. Examples include a patient returning to the clinic because a screw has backed out or a plate has fractured.

• Ensure the documentation clearly states a mechanical breakdown of the device, not an infection or other complication.
• Verify the anatomical site is specifically the bones of the hand or fingers.
• Confirm this is a subsequent encounter (D) for the complication, not the initial treatment (A) or sequela (S).
