Mech compl of internal prosth dev/grft, sequela

This code signifies a long-term or late-effect complication arising from a mechanical issue with an internal prosthetic device, implant, or graft not otherwise specified. It indicates that the initial mechanical problem has resolved, but the patient continues to experience residual effects or conditions directly attributable to that past complication.

Apply this code when documenting a patient's current condition that is a direct consequence of a previously treated or resolved mechanical complication of an internal device. This is appropriate for follow-up encounters where the original acute complication is no longer present, but its lasting impact is being addressed.

• Always sequence this code after the code(s) describing the specific sequela or current condition.
• Ensure documentation clearly links the current condition to a past mechanical complication of an internal device.
• Do not use for active, ongoing mechanical complications; use the acute T85.698A or T85.698D codes for those scenarios.
