Summary & Overview
CPT 62324: Cervical/Thoracic Epidural Infusion or Bolus Injection
CPT code 62324 covers non-image-guided injection of diagnostic or therapeutic agents into the epidural space of the cervical or thoracic spine delivered by continuous infusion or intermittent bolus. Nationally, this code is relevant for management of neck and upper back radicular pain and for documentation of procedural approach when imaging guidance is not used. Accurate coding affects clinical records, payer coverage determinations, and aggregated utilization measures across outpatient and ambulatory surgical settings.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of clinical context for epidural infusion/bolus in cervical and thoracic regions, common sites of service where this procedure is performed, and the implications of coding a procedure performed without imaging guidance. The publication also summarizes benchmarking and policy-relevant considerations that influence reimbursement and prior authorization practices for epidural injections, and highlights where Data not available in the input limits payer- or condition-specific detail.
This overview is intended for billing managers, compliance officers, clinicians involved in procedural pain management, and policy analysts who need a national-level understanding of how CPT code 62324 is used and interpreted in administrative and clinical workflows.

Clinical & Coding Specifications
Clinical Context
A 54-year-old patient with chronic cervical radiculopathy presents to an outpatient pain clinic for targeted epidural infusion therapy after conservative measures (oral analgesics, physical therapy, and a prior single-shot cervical epidural steroid injection) provided insufficient relief. The patient reports persistent neck pain radiating into the upper extremity with intermittent numbness and decreased function. The provider reviews recent imaging (MRI of the cervical spine) confirming foraminal stenosis at C5–C6 correlating with symptoms. After informed consent and review of risks, the patient is positioned for a cervical epidural injection without fluoroscopic or CT imaging guidance because of prior uncomplicated anatomy and clinician judgment.
The clinical workflow includes pre-procedure assessment (vital signs, medication reconciliation, anticoagulation check), sterile preparation and local anesthesia, insertion of the epidural catheter or needle into the cervical epidural space via an interlaminar approach, and administration of a diagnostic or therapeutic agent (local anesthetic, steroid, or analgesic) by continuous infusion or intermittent bolus per the planned treatment. Post-procedure monitoring is performed for hemodynamic stability and neurologic status prior to discharge with aftercare instructions and follow-up arranged with the referring physician.
