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

This code signifies a long-term complication where an internal fixation device, such as a plate, screw, or wire, previously implanted in the bones of the hand or fingers, has mechanically failed. This failure could involve loosening, fracture, or displacement of the device, occurring after the initial healing phase of the original injury.

Apply this code when a patient presents with symptoms or findings directly related to a mechanical breakdown of a hand or finger internal fixation device, and the breakdown is a sequela of the original treatment. This is appropriate for follow-up encounters addressing the consequences of the device failure, not the acute failure itself.

• Always use this code as a secondary diagnosis, following a code for the specific complication resulting from the device breakdown (e.g., pain, nonunion).
• Ensure documentation clearly states the mechanical nature of the breakdown and its location in the hand or fingers.
• Distinguish this from acute complications or infections related to the device, which would use different codes.
