Breakdown (mechanical) of int fix of left humerus, sequela

This code signifies a long-term complication where an internal fixation device, such as a plate, screw, or rod, implanted in the left humerus has mechanically failed or broken down. This breakdown is not an acute event but rather a sequela, indicating a residual effect or condition arising from the initial device failure.

Use this code when documenting a patient presenting with issues directly related to a previously implanted internal fixation device in the left humerus that has mechanically failed over time. This typically applies to follow-up encounters for managing the consequences of such a breakdown, rather than the initial acute failure.

• Ensure documentation clearly states the device is for the left humerus and specifies a mechanical breakdown as a sequela.
• Always code a secondary diagnosis to describe the specific nature of the sequela, such as pain, nonunion, or malunion, if applicable.
• Do not use this code for acute device failures or infections related to the device; specific codes exist for those scenarios.
