T85.828A Fibrosis due to other internal prosthetic devices, implants and grafts, initial encounter

ICD-10-CM T85.828A: Fibrosis due to other internal prosthetic devices, implants and grafts, initial encounter

ICD-10-CM code T85.828A identifies fibrosis resulting from other internal prosthetic devices, implants, and grafts during an initial encounter. This active diagnosis concept is classified as a pathologic function and is nested under a broader parent code for similar fibrotic complications involving internal prosthetics. 1 5

Plain-language overview

This diagnosis code represents a pathologic function, specifically identifying fibrosis linked to other internal prosthetic devices, implants, and grafts during the patient's initial encounter for this condition. 1 5

What this code represents

The code T85.828A is an active terminology concept that describes fibrosis due to other internal prosthetic devices, implants, and grafts, initial encounter, and it has narrower concepts within the ICD-10-CM system. 1

The parent concept for this specific diagnosis is T85.828, which broadly covers fibrosis due to other internal prosthetic devices, implants, and grafts without specifying the encounter type. 1

Coding details

The official descriptor for T85.828A is fibrosis due to other internal prosthetic devices, implants, and grafts, initial encounter, and an alternative published abbreviation is fibrosis due to other internal prosth dev/grft, init. 1

The code T85.828A is distinct from T85.828S, which is the subsequent encounter counterpart for fibrosis due to other internal prosthetic devices, implants, and grafts. 6

Documentation considerations

The official terminology record for T85.828A specifies the diagnosis as fibrosis due to other internal prosthetic devices, implants, and grafts, initial encounter, and designates its semantic type as a pathologic function. 1

What the sources add

Multiple official code systems and terminology records consistently identify T85.828A as fibrosis due to other internal prosthetic devices, implants, and grafts, initial encounter within the ICD10CM system. 1 3 5

While a federal manual lists subsequent encounter codes for various mechanical and inflammatory complications of internal prosthetics, the specific initial encounter code T85.828A is established by dedicated terminology records. 1 2

Coverage and utilization context

A Medicare billing and coding article references fibrosis codes involving cardiac and vascular prosthetic devices, but the supplied text does not explicitly detail coverage rules for the other internal prosthetic devices code T85.828A. 4
