Summary & Overview
CPT 62320: Cervical or Thoracic Epidural Injection without Imaging
CPT code 62320 identifies an epidural injection procedure in which a provider inserts a needle or catheter to deliver a diagnostic or therapeutic agent into the cervical or thoracic epidural space without imaging guidance. This code is clinically significant for management of neck and upper back radicular pain and for delivering corticosteroids or anesthetic agents for both diagnostic and therapeutic purposes. Nationally, accurate use of this code affects claims processing, clinical documentation, and appropriate site-of-service classification.
Key payers referenced include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage patterns and common modifiers in use, and it situates the procedure within clinical practice for spine pain management. Readers will find benchmarks for utilization and reimbursement practices, a summary of relevant documentation and coding considerations, and discussion of clinical context that informs proper coding and billing. The content is intended for coding professionals, practice managers, and clinicians who need a concise reference for coding, billing, and administrative workflows related to cervical and thoracic epidural injections performed without imaging.
Billing Code Overview
CPT code 62320 describes the injection of a diagnostic or therapeutic substance into the epidural space surrounding the spinal nerves in the cervical (neck) or thoracic (upper and middle back) regions. The procedure involves insertion of a needle or catheter to deliver agents such as local anesthetic, steroid, or other therapeutic/diagnostic medications without the use of imaging guidance.
-
Service type: Epidural injection to cervical or thoracic spinal nerve roots (needle or catheter placement, no imaging)
-
Typical site of service: Ambulatory surgery center, hospital outpatient department, physician office, or other outpatient procedural setting
Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents to an outpatient pain clinic with a 6-week history of worsening cervical radiculopathy characterized by neck pain radiating to the shoulder and arm, numbness in the C6 distribution, and limited activities of daily living despite conservative therapy (oral analgesics, physical therapy). Imaging (MRI) shows multilevel cervical spondylosis with right-sided foraminal narrowing at C5–C6. The interventional pain physician performs a cervical interlaminar epidural steroid injection without fluoroscopic guidance to deliver corticosteroid and local anesthetic into the epidural space for diagnostic and therapeutic effect.
The clinical workflow includes pre-procedure consent and history, verification of indications and allergies, positioning and sterile preparation, local anesthetic skin infiltration, needle insertion into the cervical epidural space (no imaging guidance), aspiration and test dosing as clinically indicated, administration of steroid and anesthetic, post-procedure observation for vital signs and neurologic status, discharge instructions, and documentation of procedure details, substances injected, and immediate response.
