When billing the G0500 and 99153 with a screening colonoscopy (G0121 or G0105) it says to bill it with modifier 33 or PT. The PT would not be correct because I am not changing the service from screening to diagnostic. Would I just use modifier 33? And would I just put that on the anesthesia codes? I am so confused on these because I billed out my anesthesia codes with the G0121 and it left a balance to the deductible and co-insurance, which should be waived when part of a screening. Which way is correct?
Thank you!
