4 inclusion terms · 1 Excludes2 · 7 use-additional codes

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for M10 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 M10 itself; “inherited from” names the category or block whose note applies here.

Inclusion Terms

Alternative terms the tabular list files under this code.

  • Acute gout
  • Gout attack
  • Gout flare
  • Podagra

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:
  • Autonomic neuropathy in diseases classified elsewhere (G99.0)
  • Calculus of urinary tract in diseases classified elsewhere (N22)
  • Cardiomyopathy in diseases classified elsewhere (I43)
  • Disorders of external ear in diseases classified elsewhere (H61.1-, H62.8-)
  • Disorders of iris and ciliary body in diseases classified elsewhere (H22)
  • Glomerular disorders in diseases classified elsewhere (N08)

Coder workflow for M10

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

Before you code M10

  1. M10 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).

    ReviewM10.0, M10.1, M10.2, M10.3, M10.4, M10.9

    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 M10?
    Yes → Select that code and continue the checks below on its own page.
    No → M10 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewM10.0, M10.1, M10.2, M10.3, M10.4, M10.9

Consider M10. 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 M10(1 note)

    Coding workflow: The conditions named in this note are not included in M10. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareM1A

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

  • Use Additional Code — after identifying M10(7 notes)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with M10 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 M10?

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

Gout is a non-billable ICD-10-CM category code (M10). A more specific billable subcode must be selected for claims submission.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name M10 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 3 Excludes1 notes across 2 chapters: E72 — Other disorders of amino-acid metabolism, E79 — Disorders of purine and pyrimidine metabolism, M1A — Chronic gout.

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

Referenced by 1 Excludes2 note: M1A — Chronic gout.

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

Referenced by 5 Code First instructions across 4 chapters: G99.0 — Autonomic neuropathy in diseases classified elsewhere, H22 — Disorders of iris and ciliary body in diseases classified elsewhere, H62.8 — Other disorders of external ear in diseases classified elsewhere, N08 — Glomerular disorders in diseases classified elsewhere, N22 — Calculus of urinary tract in diseases classified elsewhere.

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 M10 be billed directly?

No. M10 (Gout) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
