Osseous and sublux stenosis of intvrt foramina of up extrem

This code describes the narrowing of the intervertebral foramina in the cervical or thoracic spine, specifically due to bone abnormalities or vertebral misalignment (subluxation), which results in compression of nerve roots affecting the upper extremities. This stenosis can lead to radiculopathy, characterized by pain, numbness, tingling, or weakness radiating into the arm or hand.

Use this code when documentation clearly indicates osseous or subluxation-related stenosis of the intervertebral foramina impacting the upper extremity. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) demonstrating the structural narrowing and clinical findings consistent with cervical or upper thoracic radiculopathy.

• Ensure the documentation specifies "osseous" or "subluxation" as the cause of stenosis, not just general stenosis.
• Confirm the affected nerve roots are associated with symptoms in the upper extremity.
• Do not confuse with M99.57 (osseous and subluxation stenosis of neural canal of upper extremity), which refers to central canal stenosis.
