Summary & Overview

CPT 00190: Anesthesia for Procedures on Facial Bones or Skull

CPT code 00190 designates anesthesia services for surgical procedures on the facial bones or skull. This code captures intraoperative anesthetic management when care is focused on procedures involving the facial skeleton or cranial structures. It is important nationally because anesthesia coding for head and facial procedures affects provider billing, surgical care coordination, and payment classification for a range of otolaryngologic, craniofacial, and neurosurgical services. Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will learn the clinical context for use of CPT code 00190, how it relates to common surgical settings and anesthesia service lines, and where it sits in relation to closely related anesthesia codes for head and intraoral procedures. The publication outlines typical sites of service, relevant clinical scenarios, and the scope of procedures that commonly generate this anesthesia code. It also identifies related anesthesia procedure codes for head and facial operations to help clarify coding selection. Data not available in the input for payer-specific reimbursement rates and utilization benchmarks.

Billing Code Overview

CPT code 00190 describes anesthesia services provided for procedures on the facial bones or skull. The service consists of administering and managing anesthesia for patients undergoing surgical interventions involving the facial skeleton or cranial vault.

Service Type: Anesthesia for facial bones or skull procedures

Typical Site of Service: Operating room or surgical suite for head and facial surgery

Clinical & Coding Specifications

Clinical Context

A 48-year-old male with chronic otologic disease presents for surgical exploration and repair of facial bone involvement after severe chronic mucoid otitis media with recurrent infections and conductive complications. Preoperative evaluation by the anesthesiology team documents sensorineural hearing loss bilaterally (H90.3), intermittent vertigo (H81.3), and prior noise-related inner ear injury (H83.3). The surgical plan includes operative access to the facial bones and skull base for drainage, debridement, and repair under general anesthesia. The anesthesia team coordinates perioperative monitoring, airway management, intraoperative fluid and blood pressure control, and postoperative emergence in the PACU. Typical workflow: preoperative assessment and consent; anesthesia induction in the OR suite; intraoperative anesthetic management during the facial bones/skull procedure; immediate postoperative handoff to post-anesthesia care unit nursing and otolaryngology for postoperative orders and pain control. Typical site of service is the hospital operating room; ambulatory surgical centers with appropriate craniofacial capabilities may also be used when indicated. Service type: operative anesthesia for procedures on the facial bones or skull as defined by 00190.

Coding Specifications

Below are the most clinically relevant modifiers for anesthesia during procedures on the facial bones or skull and guidance on use.

Modifier	Description	When to Use
`AA`	Anesthesia services performed personally by an anesthesiologist	Use when the anesthesiologist personally performs the anesthesia services for the procedure.
`AD`	Medical supervision by a physician; more than four concurrent anesthesia procedures	Use when the physician supervises more than four concurrent anesthesia procedures.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist service for anesthesia	Use when qualified non-physician provider delivers monitored anesthesia care under appropriate supervision.
`QK`	Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals	Use when the anesthesiologist medically directs multiple concurrent anesthesia procedures (2–4).
`QS`	Monitored anesthesia care service	Use when monitored anesthesia care is provided rather than general endotracheal or regional anesthesia.
`QX`	CRNA service: CRNA service with medical direction by a physician	Use when a CRNA furnishes anesthesia services under physician medical direction.
`QY`	Medical direction of one certified registered nurse anesthetist by an anesthesiologist	Use when the anesthesiologist medically directs a single CRNA.
`QZ`	CRNA service: CRNA service without medical direction by a physician	Use when the CRNA performs the anesthesia independently and no physician direction is documented.
`62`	Two surgeons	Use when two surgeons of different specialties are required intraoperatively for the facial bones/skull procedure.
`78`	Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period	Use when the patient requires an unplanned immediate return to the OR for complications related to the facial bones/skull surgery.
`79`	Data not available in the input.
`52`	Reduced services	Use when the anesthesia service is partially reduced or discontinued at the physician's discretion.
`53`	Discontinued procedure	Use when anesthesia is provided but the surgical procedure is terminated before completion for valid reasons.
`22`	Increased procedural services	Use when the anesthesia care is substantially greater in complexity or time than typically required for `00190` (support documentation required).

Taxonomy Code	Specialty	Notes
`207L00000X`	Anesthesiology	Primary specialty responsible for delivery of anesthesia services for `00190`.
`207N00000X`	Otolaryngology	Surgical specialty commonly performing operative procedures on the facial bones or skull.
`207Y00000X`	Otolaryngology/Facial Plastic Surgery	Subspecialty performing complex facial bone and skull-related otolaryngologic procedures.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`H60.3`	Other infective otitis externa	External ear infection that may complicate otologic procedures involving the facial bones or adjacent skull structures; relevant when infection necessitates surgical intervention under anesthesia.
`H65.3`	Chronic mucoid otitis media	Chronic middle ear disease that can extend to temporal bone or mastoid regions, prompting operative management involving facial bone/skull access requiring anesthesia coded by `00190`.
`H81.3`	Other peripheral vertigo	Vestibular symptoms often associated with inner ear pathology; relevant as a comorbidity affecting perioperative assessment and anesthetic planning.
`H83.3`	Noise effects on inner ear	Prior noise-related inner ear injury influencing baseline hearing and potential postoperative counseling; relevant for surgical cases near the inner ear and skull base.
`H90.3`	Sensorineural hearing loss, bilateral	Bilateral sensorineural hearing loss is a comorbidity that affects preoperative assessment and intraoperative monitoring considerations during skull or facial bone procedures.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`00176`	Anesthesia for intraoral procedures, including biopsy; radical surgery	May be used for anesthesia services when the operative field involves intraoral access or radical oral procedures rather than external facial bones approaches; considered when procedure scope aligns with intraoral classification.
`00192`	Anesthesia for procedures on the head; radical surgery procedures on the facial bones or skull	Closely related as an alternative or adjacent anesthesia code for more extensive radical head/face/skull procedures; chosen based on the specific operative site and surgical complexity relative to `00190`.
