Osseous stenosis of neural canal of upper extremity

This code describes a narrowing of the bony canal that encases the nerves in the upper extremity. This stenosis can compress neural structures, leading to symptoms such as pain, numbness, weakness, or tingling in the arm, hand, or fingers. It specifically refers to the bony (osseous) component of the narrowing.

Use this code when documentation clearly indicates osseous stenosis affecting the neural canal of the upper extremity, such as the cervical spine (if the neural compression manifests in the upper extremity) or other bony structures along the arm. This diagnosis is typically supported by imaging studies like MRI or CT scans demonstrating the bony narrowing and its impact on neural elements.

• Differentiate from soft tissue stenosis; this code is specifically for osseous narrowing.
• Ensure the documentation specifies "upper extremity" involvement, even if the primary stenosis is in the cervical spine.
• Consider additional codes for associated neurological deficits (e.g., radiculopathy, myelopathy) if documented.
