Unsp complication of internal prosth dev/grft, sequela

This code signifies a long-term or late-effect complication arising from an internal prosthetic device, implant, or graft, where the specific nature of the complication is not documented. It indicates that the initial acute phase of the complication has passed, and the patient is now experiencing residual effects.

Use this code when a patient presents with a chronic or sequela condition directly attributable to a previously implanted device, and the medical record does not specify the exact type of complication (e.g., infection, mechanical failure, displacement). This is appropriate for follow-up encounters addressing the ongoing impact of an unspecified device-related issue.

• Only use this code when the specific complication is truly unknown or not documented.
• Always sequence this code after the code for the specific sequela or chronic condition if known.
• Avoid using this code if a more specific complication code (e.g., T85.7- for infection, T85.6- for mechanical complication) can be identified.
