Adult osteochondrosis of spine, lumbar region

This code signifies a degenerative condition affecting the vertebral endplates and adjacent bone in the lumbar spine of an adult. It involves a disturbance in the normal process of bone and cartilage formation, leading to pain and structural changes.

Assign this code when documentation explicitly states adult osteochondrosis localized to the lumbar spine. This diagnosis is typically supported by imaging studies (e.g., X-rays, MRI) demonstrating characteristic changes in the vertebral endplates and adjacent vertebral bodies.

• Differentiate from juvenile osteochondrosis (Scheuermann's disease) which affects adolescents and has different code assignments.
• Ensure documentation specifies "adult" and "lumbar region" to accurately apply this code.
• Consider sequencing with codes for associated pain (e.g., M54.5- for low back pain) if documented as a separate condition.
