CPT code 0630T identifies a CT-guided injection of a cellular or tissue–based product into a lumbar intervertebral disc and is reported for each additional level treated after the first. As regenerative and biologic disc therapies expand, accurate coding for level-based injections under image guidance is consequential for billing consistency, utilization tracking, and coverage determinations. National payers are actively evaluating clinical evidence and coverage criteria for intradiscal biologic therapies, making clear coding guidance important for providers and health plans.

This analysis covers major national payers: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service and typical sites of care, payer coverage context, common billing modifiers, and benchmarking considerations where available. The publication also outlines how 0630T relates to primary procedure reporting when multiple lumbar levels are treated and highlights practical billing elements that affect claim submission and review. Data not available in the input is noted where relevant.
