Mech compl of breast prosthesis and implant, subs encntr

This code signifies a mechanical issue with a breast prosthesis or implant that is not specifically classified elsewhere, occurring during a follow-up visit. These complications can include a range of problems such as implant migration, capsular contracture (not specified as rupture or displacement), or other structural failures of the device itself. The "subsequent encounter" designation indicates that the patient is receiving routine care or treatment for a problem identified during an initial encounter.

Use this code for follow-up visits where a patient is being managed for a mechanical complication of a breast implant or prosthesis that doesn't have a more specific ICD-10-CM code. This includes scenarios where a patient presents for evaluation of a newly developed, but non-acute, mechanical issue or for ongoing management of a previously diagnosed complication. It is appropriate when the patient is no longer in the initial phase of treatment for the complication.

• Always assign an additional code to specify the exact nature of the mechanical complication, if known and a more specific code exists (e.g., N64.89 for other specified disorders of breast).
• Ensure the "D" seventh character is appropriate for a subsequent encounter; do not use for initial treatment or sequelae.
• Distinguish from T85.41- (mechanical complication of breast prosthesis and implant, breakdown) and T85.42- (displacement) when a more precise complication is documented.
