Subluxation stenosis of neural canal of lower extremity

This code describes a narrowing of the spinal canal in the lower extremity region, specifically caused by a vertebral subluxation. This narrowing can compress the spinal cord or nerve roots, leading to neurological symptoms. It represents a structural compromise of the neural canal due to misalignment of vertebrae.

Use this code when documentation clearly indicates subluxation as the etiology of neural canal stenosis affecting the lower extremity. This typically applies to conditions like lumbar or sacral subluxation causing radiculopathy or myelopathy symptoms in the legs. Documentation should specify both the subluxation and the resulting stenosis.

• Ensure documentation explicitly links the subluxation to the stenosis; "subluxation with stenosis" is insufficient without a causal connection.
• Do not confuse with general spinal stenosis (M48.0x) unless subluxation is the definitive cause.
• Always sequence this code first if it is the primary reason for the encounter, followed by codes for associated neurological symptoms.
