If the exam was expanded to include organs outside the retroperitoneum, documentation must reflect the expansion and support billing a full or limited abdominal ultrasound (CPT 76700/76705/76706).
Claims and documentation should follow the complementary Local Coverage Determination L34577 and any applicable LCD requirements.
The medical record must include the assessment by the ordering provider as it relates to the patient's complaint for that visit.
