Spinal osteochondrosis (M42)

ICD-10 code M42 covers spinal osteochondrosis, a condition affecting the spine's bone and cartilage, with classifications distinguishing between juvenile and adult forms at various spinal sites. These codes are essential for specifying the exact location and age group affected.

The ICD-10 code for spinal osteochondrosis includes subcategories such as M42.0 for juvenile and M42.1 for adult cases, further divided by regions like cervical, thoracic, lumbar, and sacral spine. For instance, juvenile osteochondrosis codes, including M42.00 (site unspecified) and M42.04 (thoracic region), relate to conditions also known as Calve’s vertebral osteochondrosis or familial Scheuermann disease, helping clarify the diagnosis. Similarly, adult codes such as M42.12 specify cervical spine involvement. These specific codes assist medical coders in accurately documenting spinal osteochondrosis cases, capturing the patient’s age group and the precise spine location, which guides treatment decisions and insurance claims. The section also includes an unspecified category, M42.9, for cases where the exact spinal site isn't noted.
