I work for the physician side and when doing a screening and during the procedure a polyp is found we code out for the polyp and still use the V-code on the claim but not as a pointer to the cpt. How should it be coded on the hospital side.
If your billing Medicare, you code the polyp removal and add modifier PT. -PT mod. Tells Medicare that it was a screenimg turned diagnostic. If other insurance, you still code the polyp removal. From what I understand, if you remove a polyp, It's no longer a screening.
