CPT code 64484 denotes a transforaminal epidural injection of an anesthetic agent and/or steroid in the lumbar or sacral spine for each additional level treated beyond the initial level. This procedure is widely used in interventional pain management to target nerve root–mediated radicular pain and can influence utilization, prior authorization, and bundling policies across payers. Nationally, accurate use of this code affects claims adjudication and selection of facility versus office payment settings.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise overview of clinical context for transforaminal epidural injections, describes common sites of service, and outlines how payers typically classify and process add-on level services.

Readers will learn benchmarks and policy-relevant points such as typical settings where the service is rendered, payer coverage considerations, and coding context for additional-level billing. Where specific payer policy language or comparative rates are not provided in the input, the report indicates that data is not available. The content is intended to support coding accuracy, administrative clarity, and operational planning for providers and billing teams that manage interventional spine procedures.
