CPT code 62326 covers epidural injection of diagnostic or therapeutic substances into the lumbar or sacral epidural space via continuous infusion or intermittent boluses performed without imaging guidance. This procedure is widely used in pain management to deliver steroids, local anesthetics, or analgesics for radicular and lower back pain; its coding impacts claims processing, coverage determinations, and utilization monitoring across major national payers. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find a concise explanation of the clinical service and expected sites of care, along with national benchmarks for use, payer coverage considerations, and relevant billing contexts. The publication highlights how this code is positioned relative to other epidural injection codes, common billing patterns, and typical places of service. It also summarizes payer-specific approaches to preauthorization and coverage policies where available and identifies common documentation elements that support medical necessity. Data not available in the input is clearly noted where applicable. The content is intended for revenue cycle professionals, clinicians who order or perform epidural infusions, and policy analysts tracking utilization and coverage trends for interventional pain management services.
