Coder workflow for M06

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

Before you code M06

  1. M06 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).

    ReviewM06.0, M06.1, M06.2, M06.3, M06.4, M06.8, M06.9

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

  2. “Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on M06; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).

    See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →

Choose the right path

  1. Does the documentation support one of the more specific codes beneath M06?
    Yes → Select that code and continue the checks below on its own page.
    No → M06 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewM06.0, M06.1, M06.2, M06.3, M06.4, M06.8, M06.9

Consider M06. 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).
Any detail beyond this code’s title
What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.

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

Other rheumatoid arthritis is a non-billable ICD-10-CM category code (M06). 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 M06 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 Code First instructions: J84.170 — Interstitial lung disease with progressive fibrotic phenotype in diseases classified elsewhere, J84.178 — Other interstitial pulmonary diseases with fibrosis 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 M06 be billed directly?

No. M06 (Other rheumatoid arthritis) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
