CPT code 76830: Pelvic ultrasound, transvaginal, nonobstetric2026 Medicare rate & RVUs in California

Medicare pays $125.97–$160.29 for 76830 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 76830 covers

This diagnostic exam uses a vaginal transducer to obtain images of pelvic structures, commonly the uterus, endometrium, and ovaries. It is used in nonpregnant patients when a closer view is needed to evaluate concerns such as pelvic pain, abnormal uterine bleeding, or an adnexal finding. A sonographer may acquire the images, with a qualified practitioner interpreting the study; the service is commonly performed in imaging departments and gynecology offices.

Report the code for the nonobstetric transvaginal exam performed, and retain documentation of the indication, transvaginal approach, findings, and interpretation. CMS recognizes a professional component for interpretation, reported with modifier 26, and a technical component for equipment and staff, reported with modifier TC. Reporting without either modifier represents the global service, including both components.
