CPT 00940: Anesthesia for Female Perineum Procedures - OpenPayer

Summary & Overview

CPT 00940: Anesthesia for Female Perineum Procedures

CPT code 00940 designates anesthesia services for procedures on the female perineum, including biopsies of the labia, vagina, cervix, or endometrium, and is used when no other anesthesia code specifically applies. This code matters nationally because it ensures anesthesia services for a set of gynecologic procedures are captured and billed consistently when bundled or unspecified alternatives do not apply. Accurate use affects clinical documentation, payer adjudication, and aggregated reporting of anesthesia utilization for gynecologic minor procedures.

Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of the clinical context for 00940, common sites of service, typical coding interactions (including examples of surgical procedures that may bundle), and the payer landscape addressed in the publication. The report highlights coding scope, common clinical scenarios that map to this code, and where 00940 fits among related anesthesia and surgical codes. The content is written for national stakeholders involved in coding compliance, anesthesia services billing, and revenue integrity.

Clinical & Coding Specifications

Clinical Context

A 56-year-old female presents to a gynecologic outpatient surgical suite with symptomatic uterovaginal prolapse and associated vaginal wall bulging. Conservative measures have failed and she is scheduled for a limited transvaginal surgical repair with biopsy of the cervix and endometrium and possible perineal tissue release. The anesthesiologist or certified registered nurse anesthetist provides monitored anesthesia care or general anesthesia specific to procedures on the female perineum. Preoperative evaluation documents comorbidities (e.g., hypertension, obesity) and ASA physical status; informed consent for anesthesia is obtained. In the operating room, standard monitors are applied, airway management is performed as indicated, and anesthesia is administered for the duration of the perineal procedures. Post-procedure, the patient is transferred to recovery with documentation of anesthesia time, drugs, and any intraoperative events. The anesthesia service is reported with 00940 when procedures are on the female perineum (biopsy of labia, vagina, cervix, or endometrium) and when no more-specific anesthesia code applies.
