Osseous and sublux stenosis of intvrt foramin of cerv region

This code describes a narrowing of the openings (intervertebral foramina) in the cervical spine, through which nerve roots exit, caused by bone overgrowth (osseous stenosis) and/or a partial dislocation of a vertebra (subluxation). This compression can lead to nerve impingement and associated neurological symptoms in the neck and upper extremities.

Use this code when documentation clearly indicates a diagnosis of cervical intervertebral foraminal stenosis due to either bony changes or vertebral subluxation. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) demonstrating the narrowing and clinical findings consistent with nerve root compression.

• Differentiate from M99.51 (osseous and subluxation stenosis of neural canal of cervical region), which refers to central canal stenosis.
• Ensure documentation specifies "intervertebral foramina" to accurately assign this code.
• Consider additional codes for associated neurological deficits (e.g., radiculopathy) if documented.
