CPT code 00164 can be reported when an anesthesia provider performs an anesthesia service during a soft tissue biopsy of a patient’s nose and accessory sinuses.
The official description of the 00164 CPT code is: “Anesthesia for procedures on nose and accessory sinuses; biopsy, soft tissue.“
The American Society of Anesthesiologists (ASA) assigned four base units to CPT 00164.
An anesthesia provider performs a pre-operative evaluation of the patient before the soft tissue biopsy of a patient’s nose and accessory sinuses.
The anesthesia provider induces the patient and monitors the patient during the biopsy of the soft tissue of the nose and accessory sinuses. Then, another provider performs the biopsy.
The anesthesia provider notes any types and amounts of medications administered during the procedure. In addition, all monitoring forms are used, including patient responses and anesthesia care start and stop times.
Following the biopsy of the soft tissue biopsy of a patient’s nose and accessory sinuses, the anesthesia provider oversees the patient’s transfer to post-anesthesia care.
