What 57170 covers
A clinician fits a contraceptive diaphragm or cervical cap by selecting an appropriate device size and assessing how it sits in the vagina. The service is typically performed in an office gynecology or family-planning visit. The fitting is distinct from placing a pessary for pelvic support or inserting an intrauterine device. Documentation should identify the barrier device fitted, the fitting assessment, and any relevant instruction provided to the patient.
Report 57170 for the fitting service, not for a general contraception discussion alone. The record should support that a diaphragm or cap was actually assessed for fit. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

57170 billing questions
How is 57170 different from 57160?
57170 is for fitting a contraceptive diaphragm or cervical cap. Code 57160 concerns insertion of a pessary or another device, commonly for pelvic support.
Does a contraception discussion alone support 57170?
No. The record should show that a diaphragm or cap was fitted and that its fit was assessed; discussion without fitting is not this service.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What happens when another procedure is performed in the same session?
CMS applies the standard multiple-procedure reduction: the highest-valued procedure is paid in full, and other procedures are paid at 50%.
What are the assistant and surgical-team payment rules?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
