Intvrt annulus fibrosus defect, lumbosacr region, unsp size

This code describes a structural compromise of the outer fibrous ring (annulus fibrosus) of an intervertebral disc in the lower back, specifically the lumbosacral region. This defect can range from a small tear to a larger disruption, but its exact size is not specified. It often contributes to discogenic pain or instability.

Use this code when documentation clearly indicates an annulus fibrosus defect in the lumbosacral spine, and the size of the defect is not explicitly stated. This diagnosis is typically made based on imaging studies such as MRI, which may describe findings like annular tears, fissures, or disruptions.

• Ensure the documentation specifies the lumbosacral region; avoid using this code for defects in other spinal areas.
• If the size of the defect (e.g., small, large) is documented, use the more specific M51.A1- or M51.A2- codes.
• Consider sequencing this code with codes for associated conditions like disc degeneration (M51.3-), radiculopathy (M54.1-), or myelopathy (G95.81) if present and documented.
