Breakdown (mechanical) of heart valve prosthesis, init

This code signifies a mechanical failure or malfunction of an artificial heart valve, such as a fracture, detachment, or other structural compromise. This breakdown impairs the valve's ability to regulate blood flow effectively, potentially leading to symptoms like heart failure or embolization.

Apply this code when a patient presents with symptoms directly attributable to a newly identified mechanical issue with their prosthetic heart valve. This includes initial evaluations, diagnostic testing, or admissions for repair or replacement of the faulty prosthesis.

• Ensure documentation clearly specifies a mechanical breakdown, not an infection or other complication.
• This "initial encounter" code is used for the entire period a patient is receiving active treatment for the breakdown.
• Always code the specific type of heart valve prosthesis (e.g., aortic, mitral) if known, using a more specific T82.0 subcategory if available.
