Breakdown of int fix of bone of left forearm, subs

This code signifies a mechanical failure of an internal fixation device, such as a plate, screw, or rod, that was surgically implanted to stabilize a fracture in the left forearm. The breakdown indicates a structural compromise of the device itself, not an infection or other complication. This specific code is used for encounters following the initial treatment of the breakdown.

Apply this code when a patient presents for follow-up care, assessment, or treatment related to a previously identified mechanical breakdown of an internal fixation device in their left forearm. This includes situations where the patient is undergoing evaluation for revision surgery, receiving conservative management for the device failure, or monitoring the progression of the breakdown.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care for the device breakdown.
• Always sequence this code as a primary diagnosis when the reason for the encounter is the device breakdown.
• Do not use for initial treatment of the breakdown; a different seventh character would be required for that scenario.
