Question: Our anesthesiologist used a pump oxygenator to accomplish hypothermia and rewarming following a CABG procedure on a 6-month-old patient. How should we report this?
Answer: Because of the patient’s age, you should report 00561 (Anesthesia for procedures on heart, pericardial sac, and great vessels of chest; with pump oxygenator, younger than 1 year of age). For an older patient in the same situation, you would submit 00562 (Anesthesia for procedures on heart, pericardial sac, and great vessels of chest; with pump oxygenator, age 1 year or older, for all non-coronary bypass procedures [e.g., valve procedures] or for re-operation for coronary bypass more than 1 month after original operation).
Heads up: Hypothermia is bundled with CABG codes 00561-00566. That means you will not include 99116 (Anesthesia complicated by utilization of total body hypothermia) on your claim.
