Coder workflow for I25.811

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

Before you code I25.811

  1. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with I25.811. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).

    See the official tabular notes

Choose the right path

  1. Does the documentation support a condition named in I25.811’s Excludes1 note?
    Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
    No → Continue.

    ReviewI25.75

Consider I25.811. Then work the Use Additional Code note and review the Code Also 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 associated condition or complication
Whether the associated condition the title names is documented; the “with” convention presumes some links, and a provider statement that the conditions are unrelated defeats it (Guidelines I.A.15).
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

  • Excludes1 — check before selecting I25.811(1 note)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with I25.811: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareI25.75

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

  • Excludes2 — not part of I25.811(2 notes)

    Coding workflow: The conditions named in this note are not included in I25.811. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareI25.10, I5A

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

  • Use Additional Code — after identifying I25.811(10 notes)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with I25.811 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

    ReviewI25.84, I25.83, I25.82, Z77.22, Z87.891, Z57.31

    See the official tabular notes · Guidelines I.A.13

  • Code Also — related condition(1 note)

    Coding workflow: Review the related condition when both are documented and the instruction applies. A Code Also note does not fix sequencing; the order follows the circumstances of the encounter.

    See the official tabular notes · Guidelines I.A.17

Coding decision scenarios

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

Documentation: Both the condition I25.811 describes and a condition named in its Excludes1 note are documented for the same encounter.

Coding question: Can both codes be reported?

Path: Review the Excludes1 note and the excluded code, and look for a provider statement on whether the two conditions are related.

Reason: Excludes1 means the two are not coded together; the exception is when the record shows the conditions are unrelated to each other (Guidelines I.A.12.a).

ReviewI25.75

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

Coding question: Is a second code reported with I25.811?

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).

MedCoder analysis — pairs from this code’s official notes, distinctions written by MedCoder

The codes most likely to be picked instead of I25.811 — named in its own official notes, or sharing its laterality or encounter family — with what separates them and which documentation moves the case. Each links to the full comparison.

  • I25.75— Excludes1 conflict (Excludes1 — generally not reported together)

    Not coded here — the tabular list excludes this pair for the same encounter.

    Not reported together with this code, except where the two conditions are documented as unrelated.

    What moves you there: Documentation of atherosclerosis of native coronary artery of transplanted heart with angina pectoris moves the case to I25.75; the two are not reported together unless documented as unrelated.

  • I25.10— Excludes2 relationship (Informational)

    Distinct conditions — both may be reported.

    A distinct condition — both may be reported when both are documented.

  • I5A— Excludes2 relationship (Informational)

    Distinct conditions — both may be reported.

Relationships & Classification

MedCoder-derived relationships — computed from published CMS and AHRQ datasets

Other codes that name I25.811 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: I25.7 — Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris, T86.290 — Cardiac allograft vasculopathy (via I25.81.-).

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

Referenced by 2 Excludes2 notes: I74 — Arterial embolism and thrombosis (via I25.-), I82 — Other venous embolism and thrombosis (via I25.-).

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

Referenced by 3 Code First instructions: I25.82 — Chronic total occlusion of coronary artery (via I25.81.-), I25.83 — Coronary atherosclerosis due to lipid rich plaque (via I25.81.-), I25.84 — Coronary atherosclerosis due to calcified coronary lesion (via I25.81.-).

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.

MS-DRG Grouper Relationships (FY2027)

Potential MS-DRG participation — not a DRG assignment.

FY2027 MS-DRG: 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 43 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 2 MS-DRGs: DRG 302 (MDC 05), DRG 303 (MDC 05).

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