M01 — Direct infections of joint in infectious and parasitic diseases classified elsewhere
Is M01 billable?
No — M01 is a non-billable header code. M01 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 24 billable codes beneath M01.

Excludes1 — never code together
The conditions below can never be reported together with M01 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- arthropathy in Lyme disease (A69.23)
- gonococcal arthritis (A54.42)
- meningococcal arthritis (A39.83)
- mumps arthritis (B26.85)
- postinfective arthropathy (M02.-)
- postmeningococcal arthritis (A39.84)
- reactive arthritis (M02.3)
- rubella arthritis (B06.82)
- sarcoidosis arthritis (D86.86)
- typhoid fever arthritis (A01.04)
- tuberculosis arthritis (A18.01-A18.02)
Code first
The underlying condition below must be sequenced before M01. M01 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M01, but a patient may have both at the same time. When documentation supports it, M01 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)
What codes fall under M01? (1)
How long has M01 existed?
M01 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.
