M01Direct infections of joint in infectious and parasitic diseases classified elsewhere

M01 is the ICD-10-CM diagnosis code for direct infections of joint in infectious and parasitic diseases classified elsewhere. It belongs to block M00-M02 (infectious arthropathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 1 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: M01.X (elsewhere).

Don't report M01 together with the conditions in its Excludes1 note: arthropathy in Lyme disease (A69.23), gonococcal arthritis (A54.42), meningococcal arthritis (A39.83), mumps arthritis (B26.85) and 7 more.

Code first underlying disease, such as: leprosy [Hansen's disease] (A30.-), mycoses (B35-B49), O'nyong-nyong fever (A92.1) and paratyphoid fever (A01.1-A01.4).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
