Mech compl of internal prosth dev/grft, subs

This code signifies a mechanical issue, not otherwise specified, affecting an internal prosthetic device, implant, or graft that is not located in the cardiovascular, genitourinary, or nervous systems, nor is it an ocular or orthopedic device. This complication is being addressed during a follow-up encounter after initial treatment.

This code is appropriate for subsequent encounters where a patient presents with a mechanical problem (e.g., displacement, breakage, malfunction) of an internal device such as a breast implant, cochlear implant, or a non-cardiovascular/non-orthopedic graft, and the specific nature of the complication is not detailed by a more specific T85.6x subcategory.

• Always assign an additional code to specify the exact nature of the mechanical complication if known (e.g., displacement, breakage).
• Ensure the encounter is for follow-up care of the complication, not the initial treatment, due to the "D" seventh character.
• Verify the internal device is not covered by more specific T82, T83, T84, or T85.0-T85.5 categories.
