Subluxation stenosis of neural canal of upper extremity

This diagnosis code signifies a narrowing of the spinal canal or neural foramen in the cervical or upper thoracic spine, specifically caused by a vertebral subluxation. This compression can impinge upon the spinal cord or nerve roots, leading to neurological symptoms in the upper extremities.

This code is appropriate when documentation clearly indicates neural canal stenosis directly attributed to a vertebral subluxation affecting the cervical or upper thoracic regions, with resulting symptoms localized to the upper limbs. Clinical findings such as radiculopathy, paresthesia, or weakness in the arms or hands, linked to the subluxation, support its use.

• Ensure documentation explicitly links the stenosis to a subluxation and specifies upper extremity involvement.
• Do not use this code for stenosis due to degenerative changes without an identified subluxation; consider codes from the M48 series instead.
• Sequence this code as a primary diagnosis when the subluxation stenosis is the primary reason for the encounter.
