Summary & Overview
CPT 57150: Vaginal Canal Washout with Medication Instillation
CPT code 57150 represents a vaginal canal washout procedure, often performed with topical medication instillation to treat bacterial, fungal, or parasitic infections. The code is used to bill for a focused gynecologic washout that may be provided in ambulatory surgical centers, hospital outpatient departments, or clinic procedure rooms. Nationally, the code matters because it captures a targeted procedural treatment distinct from diagnostic or systemic therapies and informs payment for procedure-based vaginal care.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of clinical context and service settings, an outline of common modifiers associated with procedural services (input provided), and notes on billing considerations when a washout with medication instillation is documented. The publication highlights how the procedure is classified, typical sites of service, and what to expect in coding and claims workflows. Where input was not provided, the report indicates that data was not available in the input. The content is intended for national audiences—clinicians, coding professionals, and payers—seeking clarity on the clinical and billing definition of CPT code 57150.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult female presenting to an outpatient gynecology clinic or urgent care with symptoms of vaginal discharge, itching, odor, or irritation suggestive of infectious vaginitis (bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis) or retained intravaginal foreign material. The clinician performs a focused pelvic exam, reviews history and pregnancy status, obtains a speculum exam, and inspects the vaginal canal. When examination suggests copious discharge, adherent debris, or blood preventing adequate visualization or symptomatic relief, the provider performs a vaginal irrigation and washout (57150) using sterile saline or antiseptic solution and may instill topical medication (e.g., antifungal or antiseptic). Specimens for wet mount, pH testing, potassium hydroxide preparation, or NAAT may be collected before or after irrigation. The procedure typically occurs in an outpatient exam room, ambulatory surgery center, or emergency department for symptomatic relief, removal of irritants, or as an adjunct to medication delivery. Documentation includes indication, informed consent, description of solution and volume, any medication instilled, tolerance of procedure, and findings before and after irrigation.
