In simple words: This code covers the services of an anesthesiologist during heart bypass surgery where a machine takes over the work of the heart and lungs. The anesthesiologist prepares the patient, gives anesthesia, monitors vital signs, and gives medication during the surgery. After surgery, the anesthesiologist helps move the patient to recovery.

This CPT code encompasses anesthesia services provided during a coronary artery bypass graft (CABG) procedure requiring the use of a pump oxygenator (heart-lung machine).The anesthesiologist's responsibilities include pre-operative evaluation, induction and maintenance of anesthesia, monitoring the patient's vital signs (ECG, temperature, blood pressure, oxygen saturation, carbon dioxide levels), administering medications as needed, and overseeing the patient's transfer to post-anesthesia care.The code also includes standard monitoring; however, unusual monitoring techniques (Swan-Ganz catheters, intra-arterial lines, or central venous lines) are billed separately.

Example 1: A 65-year-old male patient undergoing CABG surgery with significant coronary artery disease requiring a pump oxygenator.The anesthesiologist manages the patient's airway, administers general anesthesia, monitors vital signs throughout the procedure, and provides post-operative care., A 72-year-old female patient with a history of hypertension and diabetes undergoing CABG surgery. The anesthesiologist carefully manages the patient's hemodynamics during the procedure with the pump oxygenator and closely monitors for any complications related to the patient’s comorbidities., A 58-year-old male patient with a history of smoking and previous myocardial infarction undergoing CABG surgery.The anesthesiologist needs to closely monitor the patient's oxygenation, ventilation, and hemodynamic status throughout the procedure while using a pump oxygenator, and manages the risks associated with the patient's smoking history.

Complete anesthesia record including pre-operative evaluation, medications administered, type and duration of monitoring, vital signs throughout the procedure, any complications or adverse events, and post-operative care.Documentation should explicitly state the use of the pump oxygenator.

** Accurate coding requires thorough documentation of the anesthesia services provided, including the specific type of monitoring, medications used, and the duration of anesthesia care.Always refer to the most current CPT manual and payer guidelines for complete and accurate coding.
