billing 2 ultrasounds

Are we able to bill a transvaginal and a transabdominal ultrasound at the same session for the same diagnosis? I cannot find any info that states we cannot but am not sure.

Coding Nonobstetrical Transvaginal/Transabdominal Ultrasounds (one opinion)
Use CPT® code 76856 or 76857, as appropriate, to bill the pelvic ultrasound
procedure. Add 76830 for the transvaginal ultrasound.
Wellmark will pay for both studies when necessary, if these studies are done
to acquire additional clinical information not evident from the initial study, or
to further investigate an area that appears suspicious or problematic. When
coding for both transabdominal and transvaginal studies in a single setting,
clearly state in the report the indication for performing the second examination: for example, for better assessment of the endometrium and/or adnexa,
etc. Bill a 59 modifier to indicate a distinct procedural service.
Medicare may deny multiple US same day/same patient. Payers generally discourage.
