M08.269 — Juvenile rheumatoid arthritis with systemic onset, unspecified knee
Is M08.269 billable?
Yes, but M08.269 is an unspecified code. M08.269 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, M08.269 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting M08.269 — the more specific alternatives are listed below.

How is M08.269 listed in the Alphabetic Index?
The Alphabetic Index lists these routes under M08.26, the nearest indexed parent of M08.269. Use them to find the family, then select the specific code.
- Still's disease or syndrome › knee (juvenile)
Excludes1 — never code together — inherited from M08
The conditions below can never be reported together with M08.269 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes1 — never code together — inherited from M08.2
The conditions below can never be reported together with M08.269 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Excludes2 — not included here — inherited from Chapter 13
