2026 ICD-10-CM Diagnosis Code T82.897AOther specified complication of cardiac prosthetic devices, implants and grafts, initial encounter
T82.897A is a billable ICD-10-CM diagnosis code for other specified complication of cardiac prosthetic devices, implants and grafts, initial encounter. The 7th character A marks it as an initial encounter code, used while the patient is receiving active treatment. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 314 through 316. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Complication of cardiovascular device, implant or graft, initial encounter.

Coding GuidelinesGuidance
The appropriate 7th character is to be added to each code from block Complications of cardiac and vascular prosthetic devices, implants and grafts (T82). Use the following options for the applicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Questions About T82.897AOverview
Is T82.897A a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified complication of cardiac prosthetic devices, implants and grafts, initial encounter on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character A in T82.897A mean?
The final character A marks the initial encounter: use it while the patient is receiving active treatment for other specified complication of cardiac prosthetic devices, implants and grafts, such as an emergency visit or first evaluation.
What MS-DRG does T82.897A group to?
When other specified complication of cardiac prosthetic devices, implants and grafts, initial encounter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 314, 315, 316, with relative weights from 0.6821 to 2.0852 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of T82.897A?
Under the General Equivalence Mappings, other specified complication of cardiac prosthetic devices, implants and grafts, initial encounter converts to ICD-9-CM 996.71 (comp-heart valve prosth) and 996.72 (comp-oth cardiac device). The mapping is approximate, so confirm the match fits the documentation.
