Question: Our physician performed a nonobstetric ultrasound of the pelvic region on a Medicare patient for the sole purpose of treating the patient for unilateral ovarian disease. I reported 76856 (Ultrasound, pelvic [nonobstetric], B-scan and/or real time with image documentation; complete), but my colleague thinks this selection is incorrect. Will you help us? Virginia Subscriber Answer: Your colleague is correct: Code 76856 is not the right selection for your physician's ultrasound. You should instead report 76857 (... limited or follow-up [e.g., for follicles]). A US study is limited if it includes a single diagnostic problem, as in your case, or a simple quadrant. A complete study, on the other hand, visualizes all of the pelvic structures (those generally within the pelvic rim and below the umbilicus) and includes a written interpretation, according to the local medical review policy from TrailBlazer Health Enterprises in Virginia. This LMRP reflects the stance taken by many LMRPs on various ultrasound sites. Medicare in Virginia and many Medicare carriers should cover your physician's US because it's medically necessary when used in the treatment of disorders of the anatomical pelvis. You should report pelvic ultrasounds when: Virginia's and other LMRPs will not cover pelvic US CPT codes and finds them not medically necessary when: Go to this Web site to find the ICD-9 codes that support medical necessity in Virginia for these US codes: http://www.asco.org/ac/1,1003,_12-002393-00_18-0017544,00.asp?state=VA.
