If a provider reviews and Ultrasound and determines the result to be one of two possibilities, how should it be coded? Both possibilities are not definitive, so would it be inappropriate, in an outpatient setting, to code these possible diagnoses? Say, for example, an Ultrasound of the Uterus shows either Polyps or fibroids, but the provider cannot know for certain yet which it is? Would the US results be ignored and the sign/symptom that lead to the US be used instead?
