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

What 01933 covers

This service covers anesthesia for therapeutic interventional radiology procedures directed to the intracranial compartment. A typical case is endovascular treatment of an intracranial aneurysm. An anesthesiologist or CRNA provides the anesthetic care in a facility while the interventional radiologist performs the procedure; the anesthesia claim represents the anesthesia service, not the radiologic intervention itself.

Choose this code for therapeutic intracranial intervention rather than anesthesia for diagnostic imaging or a procedure involving carotid or cerebral vessels. The anesthesia and operative records should identify the intracranial treatment, the procedure performed, and the anesthesia practitioner’s attendance and time. This code has 7 base units. Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor; time is reported in minutes and converted to 15-minute units to one decimal place, starting when the practitioner begins preparing the patient for anesthesia and ending when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.
