CPT Code 72193: Epidural or Caudal Injection Procedure

CPT 72193 describes: Injection, epidural or caudal, any level; including catheter placement (separate procedure).

Procedure Overview

• Technique: Needle or catheter placement into the epidural space (cervical, thoracic, lumbar, or sacral/caudal) under fluoroscopic or ultrasound guidance.
• Injectate: Typically corticosteroid (methylprednisolone, triamcinolone) ± local anesthetic (lidocaine, bupivacaine).
• Indications: Radiculopathy, spinal stenosis, disc herniation, post-laminectomy syndrome, complex regional pain syndrome.
• Catheter Placement: Included in this code when performed (e.g., for continuous infusion or multi-level spread).

Coding Nuances

• Report once per level/region per session (not per injection site).
• Do not report separately with 62320–62327 (laminar epidural) or 64479–64484 (transforaminal epidural)—those are distinct approaches.
• Imaging guidance (77003, 76942) may be reported separately if documented.
• Modifiers: 59 (distinct procedural service) if multiple regions; LT/RT for laterality; 50 for bilateral (if applicable).

Documentation Requirements

• Indication and target level(s).
• Approach (interlaminar, caudal, transforaminal—note: 72193 is interlaminar/caudal only).
• Contrast confirmation of epidural spread (fluoroscopy).
• Volume and concentration of injectate.
• Catheter placement details if performed.
• Patient tolerance and immediate post-procedure status.
