Tuberculosis of spine

This code represents an infectious disease affecting the vertebral column, specifically caused by Mycobacterium tuberculosis. It is a form of extrapulmonary tuberculosis, often leading to bone destruction, kyphosis (Pott's disease), and neurological deficits.

Apply this code when documentation confirms a diagnosis of tuberculosis directly impacting the spinal vertebrae. This typically includes findings from imaging (X-ray, MRI, CT), biopsy demonstrating granulomas or acid-fast bacilli, and positive cultures for M. tuberculosis from spinal tissue.

• Always code the underlying infectious agent (B90.0) as a secondary diagnosis.
• Specify the exact spinal region (e.g., cervical, thoracic, lumbar) if documented, using a more specific subcategory if available.
• Do not confuse with non-tuberculous osteomyelitis or other forms of spondylopathy.
