CPT code 93976: Vascular duplex, limited abdominal, pelvic, or scrotal study2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 93976 in California.

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

What 93976 covers

This study uses Doppler ultrasound to evaluate blood flow to and from organs in the abdominal, pelvic, or scrotal region when the vascular examination is limited in scope. A scrotal blood-flow assessment during evaluation for suspected torsion is one common example. Sonographers typically acquire the images and flow data in an imaging department, hospital, or office; a qualified practitioner interprets the findings.

Select 93976 when the documented vascular examination is limited, rather than a complete study reported with 93975. Documentation should identify the region or structures examined and support the Doppler assessment and interpretation. Report the professional interpretation with modifier 26 and the equipment-and-staff service with modifier TC; without either modifier, the claim represents the global service. The cardiovascular diagnostic multiple procedure reduction affects this service’s technical component.
