Summary & Overview
CPT 57170: Diaphragm or Cervical Cap Fitting and Instruction
CPT code 57170 represents the clinical service of fitting a diaphragm or cervical cap and instructing the patient on self-insertion. This procedure supports contraceptive care when the diaphragm is used and reproductive-assist or menstrual management when the cervical cap is used. Nationally, device fitting and patient education are important elements of outpatient reproductive health services because they affect patient autonomy, care quality, and potential downstream utilization.
Key payers relevant to coverage and reimbursement include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for device fitting, typical sites of service (ambulatory gynecology and family planning clinics), and the service type framed as device fitting and patient education. The publication covers benchmarks and contractual considerations where available, summarizes policy updates that affect coverage of contraceptive devices and reproductive-assist services, and explains coding implications for billing and claims processing.
This analysis equips clinical billing staff, practice managers, and policy analysts with concise context on CPT code 57170, its clinical uses, and the payer landscape to inform coding, claims submission, and administrative planning at a national level.
Billing Code Overview
CPT code 57170 describes fitting a patient with a diaphragm or cervical cap and providing instruction on self-insertion. The diaphragm is fitted and taught to the patient as a contraceptive barrier device used to prevent sperm from entering the uterus during intercourse. The cervical cap is fitted and taught for collection of menstrual flow or to assist with artificial insemination; it is explicitly noted that the cervical cap is not a contraceptive.
Service type: Device fitting and patient education / contraceptive and reproductive health device service
Typical site of service: Outpatient gynecology clinic, family planning clinic, primary care clinic, or other ambulatory care setting

Clinical & Coding Specifications
Clinical Context
A 28-year-old woman presents to an outpatient gynecology clinic requesting fitting for a barrier method of contraception. The visit includes an initial counseling session regarding diaphragm options, pelvic exam for sizing, fitting of a diaphragm, instruction and supervised practice of self-insertion and removal, and discussion of spermicide use and follow-up. Typical workflow: check-in and intake including medical and allergy history; focused sexual and contraceptive history; pelvic exam to assess cervical anatomy and determine diaphragm size; provider fits a diaphragm or cervical cap; patient practices insertion and removal under supervision; documentation of size, device type, patient tolerance, and education provided; scheduling of follow-up or replacement as indicated. Typical site of service is an outpatient ambulatory clinic or physician office; procedure may also occur in family planning clinics or community health centers. The cervical cap variant may be fitted when the intent is for menstrual collection or assistance with insemination rather than contraception; the diaphragm is fitted specifically for contraception.
