Each of the codes below is billable. Choose the one that most accurately describes the patient's diagnosis.
A defect in the annulus fibrosus of an intervertebral disc in the lumbar region where the size of the defect has not been specified in the documentation.
M51.A1 identifies a small-sized structural defect in the outer fibrous ring (annulus fibrosus) of a lumbar intervertebral disc, typically documented following discectomy or confirmed on post-operative imaging.
A large defect in the annulus fibrosus of an intervertebral disc at the lumbar level, typically documented post-discectomy and confirmed on MRI imaging.
M51.A3 identifies an annulus fibrosus defect at the lumbosacral intervertebral disc level where the defect size has not been specified in the clinical documentation.
M51.A4 identifies a small-sized defect in the annulus fibrosus of the intervertebral disc at the lumbosacral region (L5-S1 level), distinct from lumbar-level defects and from unspecified or large lumbosacral defects.
A large post-discectomy defect in the annulus fibrosus at the lumbosacral intervertebral disc level, defined as measuring at least 6 mm wide and at least 4 mm high.
