Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for T86.841 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 T86.841 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-) inherited from T86
  • malignancy associated with organ transplant (C80.2) inherited from T86
  • post-transplant lymphoproliferative disorders (PTLD) (D47.Z1) inherited from T86
  • 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 T86.841

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

Before you code T86.841

  1. T86.841 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).

    ReviewT86.8411, T86.8412, T86.8413, T86.8419

    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 T86.841?
    Yes → Select that code and continue the checks below on its own page.
    No → T86.841 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewT86.8411, T86.8412, T86.8413, T86.8419

Consider T86.841. 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 T86.841(22 notes)

    Coding workflow: The conditions named in this note are not included in T86.841. 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 T86.841(7 notes)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with T86.841 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 T86.841?

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).

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Code Overview

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name T86.841 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 (via T86.-), Z98.85 — Transplanted organ removal status (via T86.-).

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

Referenced by 9 Excludes2 notes across 2 chapters: D89 — Other disorders involving the immune mechanism, not elsewhere classified (via T86.-), T78 — Adverse effects, not elsewhere classified (via T86.-), T79 — Certain early complications of trauma, not elsewhere classified (via T86.-), T81 — Complications of procedures, not elsewhere classified (via T86.-), T82 — Complications of cardiac and vascular prosthetic devices, implants and grafts (via T86.-), T83 — Complications of genitourinary prosthetic devices, implants and grafts (via T86.-), T84 — Complications of internal orthopedic prosthetic devices, implants and grafts (via T86.-), T85 — Complications of other internal prosthetic devices, implants and grafts (via T86.-), T85.3 — Mechanical complication of other ocular prosthetic devices, implants and grafts (via T86.84.-).

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 (via T86.-), D47.Z1 — Post-transplant lymphoproliferative disorder (PTLD) (via T86.-), D89.81 — Graft-versus-host disease (via T86.-), D89.83 — Cytokine release syndrome (via T86.-).

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.
