77170 in OR

I have a physician that wants to bill 77071 for fluoro in the OR of lateral stress of the syndesmosis for widening. His documentation is:

"A tenaculum clamp was placed around the lateral malleolar plate and lateral force was applied. There was no medial widening or syndesmotic widening and the syndesmosis was deemed stable"

He is doing this during an ORIF of the ankle at an ASC.

Thanks for all input!
