Intvrt annulus fibrosus defect, large, lumbosacral region

This code signifies a significant tear or defect in the outer fibrous ring (annulus fibrosus) of an intervertebral disc within the lower back or sacral spine. This defect allows for potential herniation of the nucleus pulposus and can be a source of chronic low back pain, radiculopathy, or other neurological symptoms.

Apply this code when documentation explicitly states a "large" or "significant" annular tear or defect in the lumbosacral region, often identified through imaging studies like MRI. It is appropriate for patients experiencing symptoms directly attributable to this structural compromise of the disc.

• Ensure the documentation specifies "large" or "significant" to differentiate from smaller annular defects.
• Confirm the defect's location is specifically lumbosacral; avoid using this code for defects in other spinal regions.
• Code any associated disc herniation (e.g., M51.2-) or radiculopathy (e.g., M54.1-) separately, following sequencing guidelines.
