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 T82.9XXAOverview

Is T82.9XXA a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report unspecified complication of cardiac and vascular prosthetic device, implant and graft, initial encounter on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What does the 7th character A in T82.9XXA mean?

The final character A marks the initial encounter: use it while the patient is receiving active treatment for unspecified complication of cardiac and vascular prosthetic device, implant and graft, such as an emergency visit or first evaluation.

What MS-DRG does T82.9XXA group to?

When unspecified complication of cardiac and vascular prosthetic device, implant and graft, 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 T82.9XXA?

Under the General Equivalence Mappings, unspecified complication of cardiac and vascular prosthetic device, implant and graft, initial encounter converts to ICD-9-CM 996.71 (comp-heart valve prosth), 996.72 (comp-oth cardiac device), and 996.74 (comp-oth vasc dev/graft). The mapping is approximate, so confirm the match fits the documentation.
