M60 — Myositis
Is M60 billable?
No — M60 is a non-billable header code. M60 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 M60.

Excludes2 — not included here
The conditions below are not part of M60, but a patient may have both at the same time. When documentation supports it, M60 and the excluded code may both be reported.
- inclusion body myositis [IBM] (G72.41)
Excludes1 — never code together — inherited from M60-M63
The conditions below can never be reported together with M60 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
The conditions below are not part of M60, but a patient may have both at the same time. When documentation supports it, M60 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)
Excludes2 — not included here — inherited from M60-M63
The conditions below are not part of M60, but a patient may have both at the same time. When documentation supports it, M60 and the excluded code may both be reported.
- muscular dystrophies and myopathies (G71-G72)
What codes fall under M60? (5)
How long has M60 existed?
M60 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 M60?
ICD-10-CM declares these codes mutually exclusive with M60 — exactly one of each pair can be correct for a given encounter.
