T82.223 Leakage of biological heart valve graft

ICD-10-CM T82.223: Leakage of biological heart valve graft

ICD-10-CM code T82.223 identifies a mechanical complication involving the leakage of a biological heart valve graft. The terminology record is active for the 2026 version and classifies this concept as an injury or poisoning. It falls under the broader parent category of mechanical complications of biological heart valve grafts. 1

Plain-language overview

This diagnosis concept denotes a leakage occurring in a biological heart valve graft, which is classified within the ICD-10-CM terminology under the semantic type of injury or poisoning. 1

What this code represents

Code T82.223 represents a mechanical complication of a biological heart valve graft and has no narrower concepts within the ICD-10-CM version 2026 terminology hierarchy. 1

Coding details

The parent concept for T82.223 is T82.22, which designates a mechanical complication of a biological heart valve graft in the ICD-10-CM coding structure. 1

The official preferred name for T82.223 is leakage of biological heart valve graft, and the terminology record maintains an active status as of the 2026 release. 1 3

Documentation considerations

The official terminology record for T82.223 establishes the exact preferred name as leakage of biological heart valve graft, providing the specific text used for this diagnosis concept. 1

Clinical context

Surgical therapy remains the treatment of choice for most hemodynamically relevant heart valve lesions, although patients undergoing prosthetic valve replacement have an impaired late prognosis. 2

Patients with prosthetic heart valves need appropriate antibiotic prophylaxis for the prevention of endocarditis due to a higher infection risk compared to those with valvar heart disease. 2

What the sources add

While the terminology record defines the specific diagnosis code for biological valve graft leakage, the clinical management source provides broader operational context regarding prosthetic valve complications and treatment intensity. 1 2
