Breakdown (mechanical) of insulin pump, initial encounter

This code signifies a mechanical malfunction of an implanted or externally worn insulin pump, leading to its inability to deliver insulin as intended. This breakdown is due to a physical failure of the device itself, rather than an infection, displacement, or other complication.

Apply this code when a patient presents with symptoms related to insulin delivery disruption, and diagnostic evaluation confirms a mechanical failure of their insulin pump. This is appropriate for the initial encounter where the breakdown is identified and managed.

• Ensure documentation clearly states a "mechanical breakdown" or similar physical failure of the pump.
• Do not use for complications like infection, displacement, or leakage; separate codes exist for those.
• The "A" at the end indicates an initial encounter for this specific complication. Subsequent encounters for the same issue would use a different seventh character.
