In simple words: The anesthesiologist provides anesthesia services for a patient undergoing surgical removal of one or both adrenal glands through an incision outside the abdominal cavity lining. This includes evaluating the patient's health before the operation, administering anesthetic drugs, monitoring vital signs during the surgery, and managing post-operative care.

Anesthesia services for extraperitoneal procedures in the lower abdomen, including urinary tract; adrenalectomy.

Example 1: A 65-year-old patient with high blood pressure due to an adrenal tumor undergoes a laparoscopic adrenalectomy. The anesthesiologist provides general anesthesia and monitors the patient throughout the procedure., A 40-year-old patient with Cushing's syndrome requires open adrenalectomy. The anesthesiologist manages the complex anesthesia required for this more invasive procedure., A 25-year-old patient with a non-functioning adrenal mass undergoes robotic-assisted adrenalectomy. The anesthesiologist modifies the anesthesia plan to accommodate the robotic surgical approach.

Documentation should include pre-anesthesia evaluation, type and dosage of anesthetic agents used, monitoring methods employed, patient's response to anesthesia, start and end times of anesthesia, and any complications during the procedure. Anesthesia time is calculated from the start of anesthesia preparation in the operating room until the anesthesiologist is no longer responsible for the patient's care.

** For Medicare, anesthesia services can be billed by a qualified anesthesiologist, MD or DO (other than an anesthesiologist) qualified to administer anesthesia under state law, CRNA (under appropriate supervision), or anesthesiologist assistant (under anesthesiologist supervision). This code became effective in 1990-01-01 and has seen at least one change as of today's date, 2024-12-10. Specifically, it was added to the Inpatient Only Procedure List in 2017.
