Other spondylosis, occipito-atlanto-axial region

This code signifies degenerative changes of the spine affecting the occiput, atlas (C1), and axis (C2) vertebrae, not otherwise specified as myelopathy or radiculopathy. It encompasses various forms of spondylosis in this specific region, such as osteophyte formation, disc degeneration, or ligamentous hypertrophy, that do not meet criteria for more specific spondylosis codes.

Use this code when documentation indicates spondylosis of the occipito-atlanto-axial region without mention of myelopathy or radiculopathy. This applies to conditions like cervical osteoarthritis or degenerative disc disease localized to C0-C2. Supporting documentation should clearly specify the affected region and the absence of neurological compromise.

• Do not use this code if myelopathy (M47.11) or radiculopathy (M47.21) is documented, as those codes are more specific.
• Ensure the documentation explicitly states the involvement of the occipito-atlanto-axial region; avoid using for generalized cervical spondylosis.
• Consider laterality if specified, though this code does not have laterality distinctions.
