CPT 64469 Bilateral Thoracic Block Reimbursement

CPT code 64469 defines continuous infusion for a bilateral thoracic fascial plane block, a regional anesthesia technique used to manage chest-wall pain after surgery or trauma. This procedural code explicitly includes imaging guidance when used and captures delivery of a sustained local anesthetic infusion to both sides of the thorax. Nationally, the code is important for accurate capture of postoperative analgesia services, resource use in perioperative pain management, and appropriate facility and professional billing.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise clinical context about the block and infusion service, typical sites of service where the procedure is performed, and an outline of common billing considerations tied to continuous regional infusions. The publication summarizes benchmarks and payer coverage patterns where available, highlights relevant coding inclusions (such as imaging guidance), and identifies areas where policy clarifications or documentation detail commonly affect reimbursement. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 64469 describes continuous infusion delivery for a bilateral thoracic fascial plane block intended to provide postoperative or acute pain relief in the chest region. The code includes imaging guidance when performed.

Service type: Continuous regional nerve block infusion for bilateral thoracic fascial plane block
Typical site of service: Hospital setting, ambulatory surgery center, or other procedural environments where regional anesthesia is performed

Clinical Context

A 62-year-old patient presents post-thoracotomy for lobectomy with severe unilateral or bilateral chest wall pain inadequately controlled by systemic opioids and multimodal analgesia. The anesthesiology or regional anesthesia team assesses the patient and determines a continuous bilateral thoracic fascial plane block is indicated for targeted analgesia to the anterior and lateral chest wall. Under ultrasound guidance (and fluoroscopy if needed), bilateral perineural catheters are placed in the appropriate thoracic fascial plane and connected to ambulatory infusion pumps delivering local anesthetic. The procedure typically occurs in the operating room or a monitored perioperative block area immediately preoperatively or postoperatively. Imaging guidance is documented when used. Nursing and acute pain service staff monitor catheter sites, infusion rates, pain scores, respiratory status, and local anesthetic systemic toxicity signs during hospitalization and for ambulatory management if discharged with pumps.

`208600000X`	Physical Medicine & Rehabilitation	PM&R physicians may perform or manage regional analgesia in certain settings.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`J95.811`	Acute postprocedural pneumothorax	Chest procedures and thoracic blocks may be performed for pain control in patients recovering from thoracic interventions where pneumothorax is a potential complication to monitor.
`R07.9`	Chest pain, unspecified	Thoracic fascial plane blocks provide analgesia for severe chest wall pain when the etiology is musculoskeletal or postoperative.
`R68.83`	Chills and rigors	Included as a monitored symptom to assess systemic response to procedures; relevant to peri-procedural monitoring.
`G89.18`	Other acute postprocedural pain	Primary indication for regional continuous infusions following thoracic surgery.
`G89.29`	Other chronic pain, not elsewhere classified	May be used when fascial plane catheters are part of a multimodal plan for chronic chest wall pain management.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`64450`	Injection, anesthetic agent; other peripheral nerve or branch	May be used for single-shot thoracic paravertebral or intercostal nerve injections that can be alternatives or adjuncts to continuous thoracic fascial plane infusions.
`64447`	Injection, anesthetic agent; paravertebral sympathetic plexus (thoracic, cervical, lumbar or sacral)	Used for paravertebral injections which may be performed in similar anatomic regions for chest wall analgesia; sometimes used when paravertebral block is chosen instead of fascial plane catheter.

`76942`	Ultrasonic guidance for needle placement	Documented imaging guidance such as ultrasound is included in the descriptor for the fascial plane continuous infusion code; if payer requires separate reporting for guidance in specific circumstances, this code describes ultrasound guidance.
`99231`	Subsequent hospital inpatient care, per day	Represents daily management and evaluation of hospitalized patients receiving continuous infusion catheters; used by the inpatient team for ongoing care documentation.
