Summary & Overview

CPT 57400: Vaginal Dilation for Adhesions or Injury

CPT code 57400 represents a gynecologic operative procedure for gradual vaginal dilation when the vaginal canal is closed or narrowed by adhesions or injury. Nationally, this code identifies services intended to restore vaginal patency, often requiring procedural anesthesia and an operative setting. The code matters because it affects surgical case mix, reimbursement classification, and documentation requirements for procedures addressing vaginal stenosis or obliteration.

Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for use of the code, common sites of service, typical payer considerations, and expected documentation points. The publication provides benchmarks where available, outlines relevant coding and billing considerations, and summarizes recent policy or coverage trends that influence payment and utilization nationally. Data not available in the input are identified explicitly where applicable. This summary is intended for coding professionals, billing managers, and clinical leaders who need a clear, national-level reference on CPT code 57400 and its operational implications.

Billing Code Overview

CPT code 57400 describes a procedure in which a physician uses calibrated instruments to gradually dilate the vagina that is closed due to adhesion formation or injury. This service is a surgical procedure to restore or create a vaginal canal lumen by mechanical dilation.

Service type: Operative gynecologic procedure involving manual or instrument-assisted dilation.
Typical site of service: Ambulatory surgical center or hospital outpatient setting; may also occur in an operating room when performed with anesthesia.

Clinical & Coding Specifications

Clinical Context

A 32-year-old woman presents with progressive dyspareunia and inability to insert tampons following pelvic radiotherapy for cervical cancer two years prior. Examination demonstrates partial vaginal stenosis with scar bands and narrowing of the introitus. The gynecologist schedules a procedure for gradual mechanical dilation of the vagina under appropriate anesthesia using calibrated dilators to break adhesions and restore patency. Pre-procedure workflow includes informed consent, review of prior radiation and surgical history, targeted pelvic exam, pregnancy test if of childbearing potential, anesthesia evaluation, and documentation of baseline vaginal length and degree of stenosis. Intra-procedure steps include insertion of sequentially larger calibrated dilators with gentle, controlled pressure, lysis of superficial adhesions as needed, hemostasis, and topical estrogen or steroid application when indicated. Post-procedure care includes observation for bleeding or infection, discharge instructions on home dilation regimen, pain control, and scheduled follow-up to monitor healing and prevent re-adhesion.

CPT Code	Description	Relationship to This Procedure
`57425`	Lysis of adhesions; vaginal (separate procedure)	Performed when dense intra-vaginal adhesions require operative lysis beyond simple graduated dilation; may be billed when more extensive adhesiolysis is documented.
`57420`	Vaginal procedures, diagnostic and operative; colpotomy, incision, or drainage procedures (less specific category)	May be performed in conjunction when additional minor operative vaginal interventions are required.
`57140`	Vaginoplasty, reconstruction of vagina and repair of pelvic floor defect	Performed for definitive reconstruction when dilation alone is insufficient to restore anatomy or function.
`58150`	Removal of intrauterine device, nonobstetrical	May be performed in the same encounter if device removal is indicated before dilation (workflow-related, not directly related).
`99499`	Unlisted evaluation and management service (if no specific code applies)	Rarely used for bundled or non-standard services associated with complex perioperative management when no specific CPT is appropriate.
