About M25
M25 is the ICD-10-CM diagnosis code for other joint disorder, not elsewhere classified. It belongs to block M20-M25 (other joint disorders) 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 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: M25.0 (Hemarthrosis), M25.1 (joint), M25.2 (joint), M25.3 (joint), M25.4 (joint), M25.5 (joint), M25.6 (classified), M25.7 (Osteophyte) and 2 more.
The conditions in its Excludes2 note aren't part of M25, but may be coded alongside it if the patient has both: abnormality of gait and mobility (R26.-), acquired deformities of limb (M20-M21), calcification of bursa (M71.4-), calcification of shoulder (joint) (M75.3) and 3 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
