Degenerative cervical spine disease with confirmed nerve root involvement, producing radicular symptoms in the arm, hand, or shoulder girdle attributable to osteophyte formation, disc degeneration, or foraminal stenosis at the cervical level.

Documentation tips

What should appear in the chart to support M47.22.

• Specify the cervical region explicitly by name — 'cervical' or the affected level (e.g., C5-C6) — not just 'neck pain' or 'spine'; vague anatomy forces a drop to unspecified codes.
• Document the radiculopathy component with objective neurological findings: dermatomal distribution of pain or paresthesia, motor weakness grade, reflex changes (diminished biceps, brachioradialis, or triceps reflex), and any positive Spurling's test result.
• Cite imaging findings that support nerve root compression: MRI report language such as 'right C6 foraminal stenosis with nerve root impingement' or 'uncovertebral osteophyte encroaching on left C7 foramen' directly substantiates M47.22 over M47.812.
• Record conservative treatment history (physical therapy, NSAIDs, cervical traction) when used to establish medical necessity for interventional or surgical procedures billed alongside this diagnosis.
• If electrodiagnostic studies (EMG/NCS) were performed, document the level and laterality of the confirmed radiculopathy — this removes any ambiguity between clinical radiculopathy and myelopathy.

Common coding pitfalls

The recurring mistakes coders make with M47.22 and adjacent codes.

Source · Editorial brief grounded in CDC ICD-10-CM tabular guidance, AAOS coding references, and cited references ↓

• Using M47.22 when only degenerative disc changes are present on imaging with no documented radicular symptoms — without nerve root involvement, the correct code is M47.812 (cervical spondylosis without myelopathy or radiculopathy).
• Confusing radiculopathy with myelopathy: if cord signal change, gait disturbance, or upper motor neuron signs are documented, the correct code is M47.12, not M47.22.
• Defaulting to M47.20 (site unspecified) when the operative or consult note clearly states 'cervical' — payers flag unspecified codes and may deny or downgrade reimbursement.
• Coding M47.22 alongside M54.12 (cervical radiculopathy) when the radiculopathy is caused by the spondylosis — the radiculopathy is integral to M47.22 and should not be separately coded in that scenario.
• Applying M47.22 to cervicothoracic junction pathology: if both cervical and thoracic levels are involved at the junction, M47.23 is the precise code; M47.22 covers the cervical segment only.
