Summary & Overview
CPT 0630T: CT-Guided Lumbar Disc Cellular/Tissue Product Injection (Additional Level)
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.
Billing Code Overview
CPT code 0630T describes injection of a cellular or tissue–based product into a lumbar intervertebral disc under computed tomography (CT) guidance. This code specifically applies to each additional lumbar disc level injected after the first level. The injection may be performed unilaterally or bilaterally.
-
Service type: Image-guided biologic injection for lumbar disc therapy
-
Typical site of service: Outpatient radiology or interventional suite (CT-equipped facility) for percutaneous lumbar disc injection
Clinical & Coding Specifications
Clinical Context
A 48-year-old patient with chronic axial low back pain and imaging-confirmed degenerative lumbar disc disease at L4-L5 presents after conservative treatments (physical therapy, oral analgesics, and epidural steroid injections) provided insufficient relief. The interventional spine specialist recommends image-guided implantation of a cellular or tissue–based biologic product into the nucleus pulposus to attempt biologic repair and pain reduction.
The typical workflow: the patient undergoes pre-procedure evaluation including informed consent and review of prior imaging (MRI or CT). On the day of the procedure the patient is positioned in the CT scanner suite. Conscious sedation or monitored anesthesia care is administered per facility protocol. Under sterile technique the provider uses CT guidance to localize the target disc level and advances a spinal needle into the disc. The cellular or tissue–based product is injected into the disc space. If additional lumbar levels require injection, each additional level is billed with 0630T (the code applies to each additional level after the first). Post-procedure monitoring occurs in the recovery area until discharge criteria are met. Follow-up includes clinical assessment and repeat imaging if clinically indicated.
