Breakdown (mechanical) of insulin pump, sequela

This code signifies a long-term or late-occurring complication resulting from a mechanical failure of an insulin pump. It indicates that the initial breakdown event has led to ongoing issues or conditions that are now being addressed. This is not for the acute breakdown itself, but for its lasting consequences.

Use this code when documenting conditions or symptoms that are directly attributable to a past mechanical malfunction of an insulin pump. Examples include chronic hyperglycemia, diabetic ketoacidosis, or other metabolic derangements that developed as a direct result of the pump's failure and are now being treated. This code is appropriate for follow-up encounters addressing these residual effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a prior mechanical breakdown of an insulin pump.
• Do not use this code for the initial mechanical breakdown; instead, use the appropriate acute T85.614A or T85.614D code.
