3. CPT codes 76942, 77002, 77003, 77012, and 77021 describe radiologic guidance for needle placement by different modalities. CMS payment policy allows one unit of service for
any of these codes at a single patient encounter regardless of the number of needle placements performed. The unit of service
for these codes is the patient encounter, not number of lesions, number of aspirations, number of biopsies, number of injections,or number of localizations.
Above is from the Radiology section of the NCCI (National Correct Coding Initiative) policy manual. Below is the address that a question can be faxed to them to confirm your answer. I have wonder the same thing, but have not wrote them and just not billed the fluoro since their policy manual states fluoro can be reported once and it seems like that is be valued into the Facet injection codes, I have just taken that as once and not reported it separately like with a hip injection. But if you wrote them you might get a different interpretation.
