Adult osteochondrosis of spine, site unspecified

This code signifies a degenerative condition affecting the vertebral endplates and adjacent bone in adults, characterized by abnormal bone growth and cartilage changes within the spine. It represents a non-inflammatory disorder of bone and cartilage development, specifically osteochondrosis, occurring in an adult patient without a specified spinal location.

Apply this code when documentation indicates adult osteochondrosis of the spine, but the specific vertebral segment (e.g., cervical, thoracic, lumbar) is not clearly identified. This diagnosis is typically supported by imaging studies (X-ray, MRI) showing characteristic changes such as Schmorl's nodes, endplate irregularities, or vertebral body wedging, in the absence of trauma or infection.

• Only use this code when the specific spinal site is truly unspecified in the medical record.
• Prioritize more specific codes (M42.11-M42.18) if the spinal region is documented.
• Differentiate from Scheuermann's disease (M42.0-) which is typically diagnosed in adolescents.
