About M49

M49 is the ICD-10-CM diagnosis code for spondylopathies in diseases classified elsewhere. It belongs to block M45-M49 (spondylopathies) 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: M49.8 (elsewhere).

Don't report M49 together with the conditions in its Excludes1 note: curvature of spine in tuberculosis [Pott's] (A18.01), enteropathic arthropathies (M07.-), gonococcal spondylitis (A54.41), neuropathic [tabes dorsalis] spondylitis (A52.11) and 6 more.

Code first underlying disease, such as: brucellosis (A23.-), Charcot-Marie-Tooth disease (G60.0), enterobacterial infections (A01-A04) and osteitis fibrosa cystica (E21.0).

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