Summary & Overview
CPT 62326: Lumbar/Sacral Epidural Infusion or Intermittent Bolus, No Imaging
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.

Clinical & Coding Specifications
Clinical Context
A 54-year-old patient with chronic lumbar radiculopathy related to lumbar spondylosis and prior lumbar disc disease presents for a therapeutic caudal epidural injection without imaging guidance. The patient reports persistent low back pain radiating to the bilateral lower extremities with intermittent neurogenic claudication and failed conservative therapy including oral analgesics, physical therapy, and activity modification. The clinician reviews the history, performs a focused neurologic and spine exam, confirms indication for epidural steroid infusion/bolus, obtains informed consent, and documents medication allergies and anticoagulation status. In the procedure room the patient is positioned prone, sterile technique is used, local anesthesia is applied, and the provider advances a catheter or needle into the caudal epidural space using landmark guidance only. The provider administers a diagnostic or therapeutic agent (e.g., local anesthetic, steroid) via continuous infusion or intermittent boluses without fluoroscopic or ultrasound imaging. Post-procedure monitoring includes vital sign checks and reassessment of pain and neurologic status prior to discharge with aftercare instructions and follow-up planning.
