Summary & Overview
CPT 64468: Bilateral Thoracic Fascial Plane Block Injection
CPT code 64468 represents bilateral thoracic fascial plane block injections, a regional anesthetic procedure used to provide chest wall analgesia. The code includes any imaging guidance performed as part of the procedure. This service is clinically important for perioperative pain control and for management of acute or chronic thoracic wall pain, and it has implications for procedural workflows, facility resource use, and payer coverage policies nationwide.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common sites of service, and the types of documentation and coding considerations typically associated with image-guided regional anesthetic procedures. The publication also summarizes benchmarks and reimbursement context where available, highlights policy updates affecting coverage of regional nerve and fascial plane blocks, and outlines what to expect in claims adjudication for bilateral procedures.
This report is written for a national audience and is intended to inform clinicians, billing professionals, and policy analysts about the clinical purpose of CPT code 64468, payer coverage landscape, and areas where documentation and coding clarity commonly influence payment outcomes. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 58-year-old male with recent thoracic rib fracture and acute severe chest wall pain presents to the ambulatory interventional pain clinic for targeted regional analgesia. The patient reports constant, focal pain along the lateral chest wall that is exacerbated by breathing and movement despite oral opioids and nonsteroidal anti-inflammatory therapy. After evaluation by the interventional pain physician and review of prior imaging, the plan is to perform bilateral thoracic fascial plane blocks under sterile technique with imaging guidance to provide analgesia for rib fracture–related pain and facilitate respiratory mechanics.
The clinical workflow includes pre-procedure consent and allergy check, time-out and site marking, ultrasound and/or fluoroscopic imaging to identify the appropriate fascial plane (eg, erector spinae plane or serratus plane depending on target), bilateral needle placement, incremental injection of local anesthetic with aspiration and visualization of spread, post-procedure monitoring for vital sign stability and complications, and documentation of laterality, agents and volumes used, imaging guidance, and post-block pain reassessment. Typical sites of service are the ambulatory surgical center or hospital outpatient department; the procedure may also be performed in an inpatient setting for acute pain control.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
50 | Bilateral procedure | Use when the thoracic fascial plane block is performed bilaterally and payer requires modifier instead of modifier / pairings. |
