Osseous and sublux stenos of intvrt foramin of lumbar region

This diagnosis code signifies a narrowing of the intervertebral foramina in the lumbar spine, specifically caused by bony overgrowth (osseous) and/or a partial dislocation (subluxation) of the vertebrae. This narrowing can compress nerve roots exiting the spinal canal, leading to pain, numbness, or weakness in the lower extremities.

Use this code when documentation clearly indicates lumbar intervertebral foramen stenosis attributed to both osseous changes and vertebral subluxation. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) demonstrating the foraminal narrowing and clinical findings consistent with nerve root compression.

• Ensure documentation specifies both "osseous" and "subluxation" as contributing factors to the stenosis.
• Do not use this code if the stenosis is solely due to disc herniation or other soft tissue involvement; consider codes from the M51 series instead.
• Always sequence this code after any underlying conditions or primary diagnoses that led to the stenosis, if applicable.
