The documented study is atransvaginal pelvic ultrasound, which is coded with76830(ultrasound, transvaginal). Because the service is billed by anindependent radiologist providing only the interpretation, the correct reporting is theprofessional componentwith modifier-26(interpretation and report), not the global code. That makes76830-26the correct CPT selection. Code76817is fortransvaginal ultrasound in pregnancy/obstetric contexts, which is not supported here (the patient is menopausal and no pregnancy evaluation is described). For diagnosis, the chief complaint isuterine cramping, and the options provide pelvic pain codes;N94.89(other specified conditions associated with female genital organs and menstrual cycle) is the best match among the choices provided for uterine cramping/pelvic symptom documentation.N94.9is less specific (“unspecified”), so when a more specific option is available in the answer set, selectN94.89. Therefore, the correct combination for the interpreting independent radiologist is76830-26, N94.89.
