I have been told that CPT code 36598 cannot be billed with any other service on the same day and that it is bundled into code 71020. Can you tell me whether this is the case? I cannot find anything on the CMS website to verify this.

CPT 36598 (contrast injection(s) for radiologic evaluation of existing central venous access device, including fluoroscopy, image documentation and report) is just that. Any imaging necessary to complete the contrast study of an existing central venous access device (VAD) is included in this code unless a full and complete diagnostic venacavagram is performed.

According to the national correct coding initiative (CCI) edits (version 14.3, chapter 5), which took effect on October 10, there is no edit prohibiting the reporting of another radiologic service on the same date of service as 36598.

However, other VAD codes are listed with edits but are allowed with a modifier when appropriate. If a chest x-ray following this exam is ordered by the radiologist or other physician, for another reason or indicator (i.e., shortness of breath, etc.), it is appropriate to report both services. The chest x-ray code may require a 59 modifier to distinguish the separate service depending on your contractor.
