Hydroxyapatite deposition disease, vertebrae

This code signifies a condition characterized by the abnormal deposition of hydroxyapatite crystals within the vertebral column. This crystal deposition can lead to inflammation, pain, and functional impairment in the spine. It is a form of crystal arthropathy affecting the vertebral joints and surrounding soft tissues.

Apply this code when documentation explicitly states hydroxyapatite deposition disease affecting any part of the vertebrae. This diagnosis is typically confirmed through imaging studies (e.g., X-ray, MRI) showing calcifications, often alongside clinical symptoms like back pain or stiffness. Use when the physician's final diagnosis specifies this condition in the spine.

• Ensure documentation specifies "vertebrae" or a specific spinal region (e.g., cervical, thoracic, lumbar) to support this specific code.
• Do not confuse with other crystal arthropathies like gout or pseudogout unless specifically documented as such.
• Code any associated pain or neurological symptoms separately, following sequencing guidelines.
