Reread Descriptors to Locate the Correct X-ray Code

Question: A patient presented to our radiology practice with severe acute pain localized to their right ribcage. The documen­tation indicates the radiologist captured posteroanterior (PA), anteroposterior (AP), right lateral (RL), and right anterior oblique (RAO) views to evaluate for a rib fracture. We assigned 71111-52-RT for the procedure, but the claim was denied.

How should we have coded this service?

Answer: You need to assign only 71101 (Radiologic examination, ribs, unilateral; including posteroanterior chest, minimum of 3 views) and append modifier RT (Right side) to report this procedure.

The documentation lists four views total — PA, AP, RL, and RAO — which meets the “minimum of 3 views” listed in 71101’s descriptor as well as the “posteroanterior chest” requirement.

Additionally, you initially assigned 71111 (Radiologic examination, ribs, bilateral; including posteroanterior chest, minimum of 4 views) appended with modifiers 52 (Reduced Services) and RT. Appending modifier 52 to 71111 to show the radiologist captured X-ray views on only one side of the patient’s body is incorrect since 71101 is inherently a unilateral (one side of the body) code.

However, you may still append RT to 71101 to specify on which side of the patient’s body the procedure was performed.
