Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 00866 covers

This code represents anesthesia for extraperitoneal removal of an adrenal gland, often to treat an adrenal tumor or a hormone-producing lesion such as a pheochromocytoma. The operation may be performed by a urologic, endocrine, or general surgeon in an operating room. The anesthesia professional manages the anesthetic and perioperative monitoring during surgery in the retroperitoneal adrenal region.

Report 00866 for anesthesia for extraperitoneal adrenalectomy, rather than 00862 for a renal procedure, 00864 for total cystectomy, 00865 for radical prostatectomy, or 00868 for kidney transplantation. The operative record should identify the adrenalectomy and its approach; the anesthesia record should support the service and document anesthesia time. Medicare payment is (10 base units + time units) × the locality’s anesthesia conversion factor. Time is reported in minutes and converted to 15-minute units, computed to one decimal place; it starts when the anesthesia practitioner begins preparing the patient for anesthesia and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.
