Conn tiss and disc stenos of intvrt foramin of lumbar region

This code signifies a narrowing of the openings (intervertebral foramina) in the lumbar spine, specifically caused by issues with the surrounding connective tissue or intervertebral discs. This compression can impinge upon exiting nerve roots, leading to symptoms such as radiculopathy, pain, numbness, or weakness in the lower extremities.

Apply this code when documentation explicitly states stenosis of the lumbar intervertebral foramina due to connective tissue or disc pathology. This is often diagnosed via imaging studies (e.g., MRI, CT) showing disc herniation, bulging, or ligamentous hypertrophy contributing to foraminal narrowing. Use when the physician attributes the patient's symptoms directly to this specific anatomical compression.

• Differentiate from central canal stenosis (M99.53) or osseous stenosis (M99.63); this code is specific to connective tissue/disc involvement in the foramen.
• Ensure the documentation clearly specifies the cause of the stenosis as connective tissue or disc-related, not solely bony overgrowth.
• Always sequence this code after the underlying condition causing the stenosis, such as disc degeneration (M51.3-), if applicable and documented.
