Summary & Overview
CPT 0218T: Ultrasound-Guided Lumbar/Sacral Facet Joint Injection
CPT code 0218T identifies an ultrasound-guided injection of a diagnostic or therapeutic agent at a third-level lumbar or sacral paravertebral facet joint or the exiting nerves, with allowance for additional levels. This procedure is used to manage spinal pain and to administer anesthetic for surgical procedures, and it reflects growing use of image-guided techniques in spine care. Nationally, the code matters because it defines a discrete, image-guided interventional service that affects clinical pathways for pain management and perioperative anesthesia.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise summary of the clinical intent and typical settings for the service, payer coverage considerations and common modifiers, and the types of benchmarks and policy updates typically tracked for image-guided spinal injections. The publication provides context on clinical use, typical sites of service such as hospital outpatient departments and ambulatory surgery centers, and the practical implications for billing and documentation. Data not available in the input is noted where applicable; the focus remains on clarifying the code's clinical role, payer landscape, and what information a clinician or billing professional should expect to review when this service is billed.
Billing Code Overview
CPT code 0218T describes an ultrasound-guided injection of a diagnostic or therapeutic agent at a third level of the lumbar or sacral paravertebral facet joints or the nerves that exit those joints. The provider may inject the agent at additional spinal levels during the same encounter. The procedure is performed to relieve pain or to deliver anesthetic for a surgical procedure.
-
Service type: Image-guided spinal injection (diagnostic or therapeutic paravertebral/facet joint injection)
-
Typical site of service: Hospital outpatient department or ambulatory surgery center; may also be performed in an office setting equipped for image-guided procedures when appropriate.
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with chronic axial low back pain and suspected lumbar facet arthropathy presents to an outpatient interventional pain clinic. Conservative management including physical therapy, nonsteroidal anti-inflammatory drugs, and activity modification produced insufficient relief. After clinical evaluation and review of prior imaging demonstrating degenerative changes at the lumbar facet joints, the interventional pain specialist schedules a diagnostic or therapeutic paravertebral/medial branch injection under ultrasound guidance. The procedure is performed in an ambulatory surgery center or hospital outpatient department with continuous monitoring. Using ultrasound to identify the posterior elements, the provider injects a diagnostic anesthetic and/or therapeutic steroid at the targeted third-level lumbar or sacral paravertebral facet joints or the exiting nerves; additional contiguous levels may be injected during the same session. The procedure aims to confirm facet-mediated pain or provide temporary analgesia prior to considering radiofrequency ablation or surgical planning. Typical workflow includes pre-procedure consent and history, sterile prep and ultrasound localization, needle placement with real-time imaging and aspiration checks, controlled injection of diagnostic/therapeutic agent, post-procedure observation for adverse effects, and documentation of level(s) treated, drug(s) and volumes, imaging guidance modality, and response to injection.
