Question: Are lumbar discogenic disease and lumbar disc disease coded 722.10 (Lumbar intervertebral disc without myelopathy)? Is this appropriate for lumbar disc disease with radiculopathy? Kentucky Subscriber Answer: A more accurate code for lumbar discogenic disease (also known as lumbar disc disease) is 722.52 (Degeneration of lumbar or lumbosacral intervertebral disc). If the patient also has radiculopathy, you should submit 724.4 (Thoracic or lumbosacral neuritis or radiculitis, unspecified) as a secondary code to offer the insurer a full picture of the patient's condition.
