About M24
M24 is the ICD-10-CM diagnosis code for other specific joint derangements. 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: M24.0 (joint), M24.1 (disorders), M24.2 (ligament), M24.3 (classified), M24.4 (joint), M24.5 (joint), M24.6 (joint), M24.7 (acetabuli) and 2 more.
Don't report M24 together with the conditions in its Excludes1 note: current injury - see injury of joint by body region.
The conditions in its Excludes2 note aren't part of M24, but may be coded alongside it if the patient has both: ganglion (M67.4), snapping knee (M23.8-) and temporomandibular joint disorders (M26.6-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
