Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for D61.81 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 D61.81 itself; “inherited from” names the category or block whose note applies here.

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Excludes2 — Not Included Here

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

Coder workflow for D61.81

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

Before you code D61.81

  1. D61.81 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).

    ReviewD61.810, D61.811, D61.818

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

  2. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with D61.81. 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 one of the more specific codes beneath D61.81?
    Yes → Select that code and continue the checks below on its own page.
    No → D61.81 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewD61.810, D61.811, D61.818

  2. Does the documentation support a condition named in D61.81’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.

    ReviewD61.9, D61.82, D61.01, C91.4, B20, D47.1

Consider D61.81. Then 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).

Official instructions as workflow

  • Excludes1 — check before selecting D61.81(7 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with D61.81: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareD61.9, D61.82, D61.01, C91.4, B20, D47.1

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

  • Excludes2 — not part of D61.81(2 notes)

    Coding workflow: The conditions named in this note are not included in D61.81. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Coding decision scenarios

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

Documentation: Both the condition D61.81 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).
