About M49.8

M49.8 is the ICD-10-CM diagnosis code for spondylopathy in diseases classified elsewhere. It belongs to category M49 (spondylopathies in diseases classified elsewhere), 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: M49.80 (site unspecified), M49.81 (occipito-atlanto-axial region), M49.82 (cervical region), M49.83 (cervicothoracic region), M49.84 (thoracic region), M49.85 (thoracolumbar region), M49.86 (lumbar region), M49.87 (lumbosacral region) and 2 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.
