About M47

M47 is the ICD-10-CM diagnosis code for spondylosis. 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: M47.0 (syndromes), M47.1 (myelopathy), M47.2 (radiculopathy), M47.8 (spondylosis) and M47.9 (unspecified).

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