T86.8413 ICD-10-CM Code: Corneal transplant failure, bilateral

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 124 — OTHER DISORDERS OF THE EYE WITH MCC OR THROMBOLYTIC AGENT (MDC 02)
  • MS-DRG 125 — OTHER DISORDERS OF THE EYE WITHOUT MCC (MDC 02)

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

Corneal transplant failure, bilateral is a billable ICD-10-CM diagnosis code (T86.8413).

Official Tabular Instructional Notes

Sequencing, inclusion, and exclusion notes published for T86.8413 in the official ICD-10-CM tabular list.

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 to identify other transplant complications, such as:
  • graft-versus-host disease (D89.81-)
  • malignancy associated with organ transplant (C80.2)
  • post-transplant lymphoproliferative disorders (PTLD) (D47.Z1)
  • 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)

Frequently Compared Codes

The official Excludes notes on T86.8413 name these codes. Each comparison page covers when the two can — or must not — be reported together.

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 8 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 2 MS-DRGs: DRG 124 (MDC 02), DRG 125 (MDC 02).

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

Clinical classification (AHRQ CCSR):INJ036 — Complication of transplanted organs or tissue, initial encounter (default).
