About M47.0

M47.0 is the ICD-10-CM diagnosis code for anterior spinal and vertebral artery compression syndromes. It belongs to category M47 (spondylosis), 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 2 subcodes must be used instead.

Within M47 (spondylosis), M47.0 is specifically for anterior spinal and vertebral artery compression syndromes. Related codes cover other spondylosis with myelopathy (M47.1), other spondylosis with radiculopathy (M47.2), other spondylosis (M47.8) and unspecified (M47.9).

To report this condition, pick the subcode that matches the documentation: M47.01 (syndromes) and M47.02 (syndromes).

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