CPT 00170 | Anesthesia Intraoral Procedures (Including Biopsy)

CPT code 00170 can be reported when an anesthesia provider performs an anesthesia service during an intraoral procedure on a patient. A biopsy is included in this procedure.


The official description of the 00170 CPT code is: “Anesthesia for intraoral procedures, including biopsy; not otherwise specified.

Billing Guidelines

The American Society of Anesthesiologists (ASA) assigned five base units to CPT 00170.

Diagnosis coding is important to substantiate coverage of CPT code 00170.

Anesthesia provided in connection with the care, treatment, filling, removal, or replacement of teeth or structures directly supporting the teeth is non-covered by Medicare.

Anesthesia for dental restoration should be billed under CPT anesthesia code 00170 with the appropriate modifier, minutes and most specific diagnosis code.

Reimbursement is formula-based, with no additional payment being made for a biopsy. A provider does not have to perform a biopsy to bill this code.


Before an intraoral procedure, an anesthesia provider performs a pre-operative evaluation of the patient.

The anesthesia provider induces and monitors the patient during the intraoral procedure. A biopsy is included. The intraoral procedure is provided by another health provider.

The anesthesia provider notes any types and amounts of medications administered during the intraoral procedure. All forms of monitoring are used, and patient responses are the start and stop times of anesthesia care are monitored. 

Following the intraoral procedure, the anesthesia provider oversees the patient’s transfer to post-anesthesia care.
