ICD-10-CM T82.7XXA
CMSSource: CMS FY 2026 ICD-10-CM dataset · Effective Oct 1, 2025 – Sep 30, 2026

T82.7XXA is a billable ICD-10-CM diagnosis code for infection and inflammatory reaction due to other cardiac and vascular 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. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 213 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Complication of cardiovascular device, implant or graft, initial encounter.

T82.7XXA no longer risk-adjusts for Medicare Advantage: it mapped to HCC 176 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 176, ESRD (V21) category 176, and ESRD (V24) category 176 for payment year 2026.

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

Clinical InformationClinical

  • Candidemia

    a form of invasive candidiasis where species of candida are present in the blood.

    the presence of fungi circulating in the blood. opportunistic fungal sepsis is seen most often in immunosuppressed patients with severe neutropenia or in postoperative patients with intravenous catheters and usually follows prolonged antibiotic therapy.

  • Candida

    a genus of yeast-like mitosporic saccharomycetales fungi characterized by producing yeast cells, mycelia, pseudomycelia, and blastophores. it is commonly part of the normal flora of the skin, mouth, intestinal tract, and vagina, but can cause a variety of infections, including candidiasis; onychomycosis; vulvovaginal candidiasis; and candidiasis, oral (thrush).

Questions About T82.7XXAOverview

Is T82.7XXA a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report infection and inflammatory reaction due to other cardiac and vascular 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 T82.7XXA mean?

The final character A marks the initial encounter: use it while the patient is receiving active treatment for infection and inflammatory reaction due to other cardiac and vascular devices, implants and grafts, such as an emergency visit or first evaluation.

What MS-DRG does T82.7XXA group to?

When infection and inflammatory reaction due to other cardiac and vascular 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.

Is T82.7XXA a CC or MCC?

CMS lists T82.7XXA as a CC (complication or comorbidity) for FY 2026. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 213 closely related codes in its exclusion list.

What is the ICD-9 equivalent of T82.7XXA?

Under the General Equivalence Mappings, infection and inflammatory reaction due to other cardiac and vascular devices, implants and grafts, initial encounter converts to ICD-9-CM 996.61 (react-cardiac dev/graft) and 996.62 (react-oth vasc dev/graft). The mapping is approximate, so confirm the match fits the documentation.

Does T82.7XXA risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage. T82.7XXA mapped to HCC 176 in the retired CMS-HCC V24 model, which last determined payment in 2025, but it maps to no category in the live V28 model; see all codes that no longer risk-adjust. It still risk-adjusts in the PACE (CMS-HCC V22) category 176 (Complications of Specified Implanted Device or Graft), ESRD (V21) category 176 (Complications of Specified Implanted Device or Graft), and ESRD (V24) category 176 (Complications of Specified Implanted Device or Graft).
