Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for T86 in the official ICD-10-CM tabular list, quoted as published.

Source: CMS/CDC — ICD-10-CM Tabular ListRelease: FY2026Effective: October 1, 2025

Notes without a marker are published on T86 itself; “inherited from” names the category or block whose note applies here.

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) inherited from T80-T88
  • Use additional code(s) to identify the specified condition resulting from the complication inherited from T80-T88
  • Use additional code to identify devices involved and details of circumstances (Y62-Y82) inherited from T80-T88

Coder workflow for T86

MedCoder structured workflow — derived from this code’s own official record

Before you code T86

  1. T86 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).

    ReviewT86.0, T86.1, T86.2, T86.3, T86.4, T86.5, T86.8, T86.9

    See the relationships section · Guide: How to choose an ICD-10-CM code →

Choose the right path

  1. Does the documentation support one of the more specific codes beneath T86?
    Yes → Select that code and continue the checks below on its own page.
    No → T86 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewT86.0, T86.1, T86.2, T86.3, T86.4, T86.5, T86.8, T86.9

Consider T86. Then work the Use Additional Code note, and confirm the code is valid for the date of service in the Verify section.

Documentation check

The provider’s diagnostic statement
Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
The conditions the Use Additional Code note names
Reported with this code when documented; a conditional instruction (“if applicable”, “if known”) applies only when the record supports it.

Official instructions as workflow

  • Excludes2 — not part of T86(21 notes)

    Coding workflow: The conditions named in this note are not included in T86. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    See the official tabular notes · Guidelines I.A.12.b

  • Use Additional Code — after identifying T86(7 notes)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with T86 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Documentation: A condition the Use Additional Code note names is documented.

Coding question: Is a second code reported with T86?

Path: Review the Use Additional Code note and the code it names.

Reason: The additional code is reported when the record documents the condition; a conditional instruction applies only when its condition is met (Guidelines I.A.13).

Code Overview

Complications of transplanted organs and tissue is a non-billable ICD-10-CM category code (T86). A more specific billable subcode must be selected for claims submission.

Verbatim excerpts from the ICD-10-CM Official Guidelines for Coding and Reporting (CMS/NCHS) that govern this code.

Chapter 2: Neoplasms (C00-D49 )

r. Malignant neoplasm associated with transplanted organ A malignant neoplasm of a transplanted organ should be coded as a transplant complication. Assign first the appropriate code from category T86.-, Complications of transplanted organs and tissue, followed by code C80.2, Malignant neoplasm associated with transplanted organ. Use an additional code for the specific malignancy. s. Breast Implant Associated Anaplastic Large Cell Lymphoma Breast implant associated anaplastic large cell lymphoma (BIA-ALCL) is a type of lymphoma that can develop around breast implants. Assign code C84.7A, Anaplastic large cell lymphoma, ALK-negative, breast, for BIA-ALCL or C84.7B, Anaplastic large cell lymphoma, ALK-negative, in remission, for BIA- ALCL in remission. Do not assign a complication code from chapter 19.

Chapter 19: Injury, poisoning, and certain other consequences of external causes (S00-T88)

(a) Transplant complications other than kidney Codes under category T86, Complications of transplanted organs and tissues, are for use for both complications and rejection of transplanted organs. A transplant complication code is only assigned if the complication affects the function of the transplanted organ. Two codes are required to fully describe a transplant complication: the appropriate code from category T86 and a secondary code that identifies the complication.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name T86 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 2 Excludes1 notes across 2 chapters: T88.7 — Unspecified adverse effect of drug or medicament, Z98.85 — Transplanted organ removal status.

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 8 Excludes2 notes across 2 chapters: D89 — Other disorders involving the immune mechanism, not elsewhere classified, T78 — Adverse effects, not elsewhere classified, T79 — Certain early complications of trauma, not elsewhere classified, T81 — Complications of procedures, not elsewhere classified, T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts, T83 — Complications of genitourinary prosthetic devices, implants and grafts, T84 — Complications of internal orthopedic prosthetic devices, implants and grafts, T85 — Complications of other internal prosthetic devices, implants and grafts.

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

Referenced by 4 Code First instructions across 2 chapters: C80.2 — Malignant neoplasm associated with transplanted organ, D47.Z1 — Post-transplant lymphoproliferative disorder (PTLD), D89.81 — Graft-versus-host disease, D89.83 — Cytokine release syndrome.

Each of these codes carries a Code First note naming this condition — when that code is reported, THIS code is sequenced first, ahead of it.

Common coding questions

Can T86 be billed directly?

No. T86 (Complications of transplanted organs and tissue) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
