Coder workflow for M05.17
MedCoder structured workflow — derived from this code’s own official record
Before you code M05.17
- M05.17 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).
ReviewM05.171, M05.172, M05.179
See the relationships section · Guide: How to choose an ICD-10-CM code →
- M05.17’s title joins a condition with an associated condition or complication. Confirm each component is documented. Where the classification presumes the link through the “with” convention, only a provider statement that the conditions are unrelated defeats it. A combination code is assigned only when it fully identifies the documented conditions; a required second code for the stage, type or manifestation is still reported when the notes ask for it (Guidelines I.B.9, I.A.15).
- Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with M05.17. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).
Choose the right path
- Does the documentation support one of the more specific codes beneath M05.17?
Yes → Select that code and continue the checks below on its own page.
No → M05.17 cannot be reported as written; query for the specificity its subcategory needs. - Does the documentation support a condition named in M05.17’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.
Consider M05.17. 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).
- 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).
Official instructions as workflow
Excludes1 — check before selecting M05.17(3 notes)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with M05.17: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: Both the condition M05.17 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).
Documentation: Only one of the components this code’s title joins is documented.
Coding question: Is M05.17 supported?
Path: Review the code for the documented component on its own.
Reason: A combination code is assigned only when it fully identifies the documented conditions; otherwise the documented component takes its own code (Guidelines I.B.9).
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.

Relationships & Classification
MedCoder-derived relationships — computed from published CMS and AHRQ datasets
Other codes that name M05.17 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 1 Excludes1 note: R76.81 — Abnormal rheumatoid factor and anti-citrullinated protein antibody without rheumatoid arthritis (via M05.-).
These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
Referenced by 2 Code First instructions: J84.170 — Interstitial lung disease with progressive fibrotic phenotype in diseases classified elsewhere (via M05.-), J84.178 — Other interstitial pulmonary diseases with fibrosis in diseases classified elsewhere (via M05.-).
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.
Referenced by 1 Code Also instruction: I27.21 — Secondary pulmonary arterial hypertension (via M05.-).
These codes suggest coding this condition alongside when both are present.

Common coding questions
MedCoder editorial
Can M05.17 be billed directly?
No. M05.17 (Rheumatoid lung disease with rheumatoid arthritis of ankle and foot) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
