Summary & Overview
CPT 33140: Laser Revascularization of Heart via Thoracotomy
CPT code 33140 identifies laser revascularization of the heart performed through a thoracotomy. This surgical, cardiac revascularization code captures use of laser to create myocardial channels or otherwise restore blood flow via an open thoracic approach. The code matters nationally as it relates to specialty cardiac surgery billing, inpatient and hospital outpatient reimbursement, and classification of laser-assisted myocardial revascularization procedures.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise account of the code's clinical context, typical sites of service, and the payer landscape relevant to coverage and claims processing. The publication provides benchmark-oriented information, policy and coding considerations that affect billing and claims submission, and how this procedure is positioned within cardiac surgical services.
The audience will gain a practical snapshot of where CPT code 33140 fits in surgical service lines, what settings commonly deliver the service, and which major payers are relevant for coverage and claims. Data not available in the input will be explicitly noted where applicable in detailed sections.
Billing Code Overview
CPT code 33140 describes laser revascularization of the heart performed via thoracotomy. The procedure uses laser technology to restore or improve myocardial blood flow by creating channels in the myocardium through a surgical thoracotomy approach.
Service Type: Surgical, cardiac revascularization (laser-assisted)
Typical Site of Service: Inpatient or outpatient hospital surgical suite (thoracotomy approach)
Clinical & Coding Specifications
Clinical Context
A typical patient for 33140 is a 68-year-old male with refractory angina due to diffuse coronary artery disease not amenable to percutaneous coronary intervention or conventional coronary artery bypass grafting. He has progressive exertional chest pain despite maximal medical therapy and prior failed PCI attempts. Diagnostic workup includes coronary angiography confirming distal and intramyocardial vessel disease. The cardiac surgery team schedules a laser revascularization procedure performed via left thoracotomy under general anesthesia. Intraoperative workflow includes single-lung ventilation, median or anterolateral thoracotomy exposure of the pericardium, epicardial mapping to localize ischemic territories, application of the laser to create channels in the ischemic myocardium, hemostasis, chest tube placement, and layered closure. Postoperative care occurs in a cardiac intensive care or step-down unit with continuous telemetry, analgesia, respiratory support as needed, chest tube management, and monitoring for bleeding or myocardial injury. Discharge planning includes wound care, activity restrictions, cardiac rehabilitation referral, and outpatient cardiology follow-up for ischemic symptom reassessment.
