M08 — Juvenile arthritis
Not billable
Is M08 billable?
No — M08 is a non-billable header code. M08 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 60 billable codes beneath M08.

M08 at a glance
| Code | M08 |
|---|---|
| Description | Juvenile arthritis |

| Valid for encounters | October 1, 2026 – September 30, 2027 |
Excludes1 — never code together
The conditions below can never be reported together with M08 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code also
Two codes may be needed to describe the condition fully. Whether M08 is sequenced first depends on the reason for the encounter.
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M08, but a patient may have both at the same time. When documentation supports it, M08 and the excluded code may both be reported.
- arthropathic psoriasis (L40.5-)
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- compartment syndrome (traumatic) (T79.A-)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

How long has M08 existed?
M08 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with M08?
ICD-10-CM declares these codes mutually exclusive with M08 — exactly one of each pair can be correct for a given encounter.
