T82.856A ICD-10-CM Code: Stenosis of peripheral vascular stent, initial encounter

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.

  • MS-DRG 314 — OTHER CIRCULATORY SYSTEM DIAGNOSES WITH MCC (MDC 05)
  • MS-DRG 315 — OTHER CIRCULATORY SYSTEM DIAGNOSES WITH CC (MDC 05)
  • MS-DRG 316 — OTHER CIRCULATORY SYSTEM DIAGNOSES WITHOUT CC/MCC (MDC 05)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Official Registry Overview & Definition

Stenosis of peripheral vascular stent, initial encounter is a billable ICD-10-CM diagnosis code (T82.856A).

Official Tabular Instructional Notes

Sequencing, inclusion, and exclusion notes published for T82.856A in the official ICD-10-CM tabular list.

Inclusion Terms

Alternative terms the tabular list files under this code.

  • In-stent stenosis (restenosis) of peripheral vascular stent
  • Restenosis of peripheral vascular stent

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

Use Additional Code

Supplementary codes the tabular list directs you to add.

  • Use additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
  • Use additional code(s) to identify the specified condition resulting from the complication
  • Use additional code to identify devices involved and details of circumstances (Y62-Y82)

Indexed Clinical Terms (5)

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code.

  • Restenosis, stent, vascular, end stent, within the stent, peripheral
  • Restenosis, stent, vascular, in stent, peripheral vessel
  • Stenosis, stenotic (cicatricial), artery NEC, stent, peripheral

Potential MS-DRG Relationships (FY2026)

CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 213 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 3 MS-DRGs: DRG 314 (MDC 05), DRG 315 (MDC 05), DRG 316 (MDC 05).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Clinical classification (AHRQ CCSR):INJ033 — Complication of cardiovascular device, implant or graft, initial encounter (default).
