T82.33 Leakage of other vascular grafts

ICD-10-CM Diagnosis Code T82.33: Leakage of other vascular grafts

ICD-10-CM code T82.33 denotes the diagnosis 'Leakage of other vascular grafts' and is an active concept classified under injury or poisoning. It falls under the parent category T82.3 for mechanical complications of other vascular grafts. This terminology record is maintained as an official coding concept. 1

Plain-language overview

This diagnosis concept identifies the leakage of other vascular grafts and is classified within the coding system under the semantic type of injury or poisoning. 1

What this code represents

Code T82.33 represents the specific mechanical complication of leakage occurring in other vascular grafts, functioning as an active terminology record without narrower child concepts beneath it. 1

Coding details

The code T82.33 exists within a hierarchy under parent code T82.3, which broadly covers mechanical complications of other vascular grafts, and further expands into more specific encounter codes like T82.338D and T82.338S. 1 3 4

While T82.33 is the base category, billing and coding articles identify T82.338D for initial encounters and T82.338S for subsequent encounters of other vascular graft leakage. 3

Documentation considerations

The terminology hierarchy shows T82.33 expands into terminal subcategory T82.338, which includes specific encounter extensions for initial and subsequent encounters listed in billing articles. 3 4

Clinical context

Synthetic vascular grafts provide immediate availability in clinical practice but experience high failure rates in small-diameter applications due to factors including thrombogenicity, infections, and intimal hyperplasia. 2

What the sources add

A terminology record establishes the official active label and semantic type for T82.33, while a billing article provides operational context by illustrating its expansion into specific initial and subsequent encounter codes. 1 3

Coverage and utilization context

Specific T82.338D and T82.338S encounter codes appear within a Medicare billing and coding article for non-invasive arterial duplex ultrasounds of the upper and lower extremities. 3
