Summary & Overview
CPT 01966: Anesthesia for Induced Abortion Procedures
Headline: New Focus on Anesthesia Reporting for Induced Abortion Procedures
Lead: CPT 01966 designates anesthesia services for induced abortion procedures and is a critical coding element for documenting peri-procedural anesthetic care. Accurate use of this code affects clinical communication, billing integrity, and payer adjudication nationally.
What this code represents and why it matters: CPT 01966 captures anesthesiology services specific to induced abortion procedures. Nationally, clear reporting supports appropriate clinical records, resource allocation within hospital settings, and consistent payer processing. Anesthesia documentation linked to this code can influence care coordination and facility planning for inpatient services.
Key payers covered: This publication covers Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare and how CPT 01966 is recognized across major commercial payers.
What readers will learn: The piece provides benchmarks for coding frequency where available, summarizes payer coverage patterns, clarifies common clinical settings and service expectations, and outlines related billing considerations. Also included will be context on associated clinical scenarios and comparisons to related anesthesia codes.
Limitations: Data not available in the input for certain service line details and utilization metrics. The content is intended to inform coding and policy understanding rather than provide clinical guidance.
CPT Code Overview
CPT 01966 describes anesthesia services provided for induced abortion procedures. This code is used to report the anesthesiology care associated with termination of pregnancy when anesthesia is administered to facilitate the procedure.
Service Type: Anesthesiology
Typical Site of Service: Inpatient Hospital (POS 21)
Clinical & Coding Specifications
Clinical Context
A 28-year-old patient presents to the inpatient hospital for a planned induced abortion procedure with anesthesia provided in the operating room. The patient had preoperative evaluation by the anesthesiology team, informed consent documented, and standard monitoring initiated. General or regional anesthesia is administered based on gestational age, patient factors, and surgical requirements. The anesthesiologist or CRNA documents airway management, anesthetic agents, hemodynamic stability, and postoperative recovery in the PACU prior to discharge or admission.
Coding Specifications

Modifiers
-
AA: Anesthesia services performed personally by anesthesiologist — used when the anesthesiologist personally performs all anesthesia services for the procedure. -
QX: CRNA service with medical direction by a physician — used when a Certified Registered Nurse Anesthetist provides anesthesia under the medical direction of a physician, and reporting requires the CRNA’s service code with this modifier. -

Related Diagnoses
-
O82— Encounter for cesarean delivery without indicationRelevance: A cesarean delivery encounter may coexist with or complicate reproductive care; anesthesia planning differs but billing capture lists this code as a related obstetric diagnosis.
-
O75.82— Maternal exhaustion complicating labor and deliveryRelevance: Maternal exhaustion can affect anesthesia risk stratification and intraoperative management for obstetric procedures.
-
O62.0— Primary inadequate contractionsRelevance: Inadequate contractions may lead to procedural decisions impacting anesthesia timing and technique in obstetric care.
-
O66.9— Obstructed labor, unspecifiedRelevance: Obstructed labor is an obstetric complication that alters anesthesia planning and urgency of operative interventions.
-
O34.211— Maternal care for low transverse scar from previous cesarean deliveryRelevance: A prior low transverse cesarean scar informs anesthesia and surgical planning due to potential adhesions or consideration of repeat cesarean management.
Related CPT Codes
| CPT Code | Description | Clinical relationship |
|---|---|---|
01965 | Anesthesia for incomplete or missed abortion procedure | Alternative or related anesthesia code for abortion procedures that are incomplete or missed; may be used in workflows when the procedural context differs from a planned induced abortion. |
01965is commonly considered an alternative anesthesia code for abortion-related procedures and may be used instead of01966when the procedure documented is an incomplete or missed abortion rather than an induced abortion.
National Reimbursement Benchmarks
National commercial averages sit well above Medicare for this code; BUCA (average commercial) has a mean rate of $125.78 compared with Medicare, which is not provided in the input (reported here as unavailable). Aetna, Blue Cross Blue Shield, and Cigna report higher mean rates than BUCA, while UnitedHealth Group reports a substantially lower mean.
Dispersion measured as the difference between the 75th and 25th percentiles varies across payers. Cigna and Aetna show the widest spreads (Cigna: $258.00 range; Aetna: $284.00 range), indicating greater variability in contracted rates, while UnitedHealth Group and BUCA are the tightest (UHC: $25.08 range; BUCA: $131.00 range). The table and chart below present the full percentile and mean-rate breakdown.

Alaska Benchmarks
Alaska displays a significant spread in reimbursement rates for CPT code 01966, with Blue Cross Blue Shield showing the widest range between the 25th and 75th percentiles ($298.50 minus $225.80 = $72.70). In contrast, Aetna, Cigna, and UnitedHealth Group have much narrower spreads, each with only a few dollars difference between their percentiles. This indicates that Blue Cross Blue Shield's rates are not only the highest but also more variable compared to other payers in the state.
Compared to national averages, Alaska's mean rates for most payers are substantially higher, particularly for Blue Cross Blue Shield and BUCA.
