CPT Code Overview
CPT code 33510 represents a coronary artery bypass procedure using a single venous graft. This code is used in cardiothoracic surgery to treat patients with coronary artery disease by bypassing blocked arteries with a vein graft. The procedure is typically performed in an inpatient hospital setting (Place of Service 21), reflecting its complexity and the need for specialized postoperative care. This code is central to the management of advanced cardiovascular conditions requiring surgical intervention.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult patient admitted to an inpatient hospital setting with significant atherosclerotic heart disease affecting the native coronary arteries. The patient may present with symptoms such as chest pain, unstable angina, or evidence of myocardial ischemia. After diagnostic evaluation, the patient is determined to require surgical revascularization. The procedure performed is a coronary artery bypass graft (CABG) using a single venous graft, as described by CPT code 33510. The clinical workflow includes preoperative assessment, intraoperative bypass using a vein graft to restore blood flow to a blocked coronary artery, and postoperative care in a cardiothoracic unit.
