I am also confused. My physicians did a screening colonoscopy on a patient and found polyps in 2007, 10 years ago. We coded it 45380PT , V76.51, 211.3. Pt came back 3 years later, 2010, for screening/surveillance and nothing was found, G0121, v12.72. Patient had another colon 3 years after the last one ,2013, and nothing found again, G0121,v12.72. Pt is now coming back in for screening colon. My question is, the pt had a screening 10 years ago and has personal history of polyps but nothing has been found for 10 years, can we bill a true screening, G0105, Z12.11 or do we still need to use the personal history code Z86.010? Will copay and deductibles apply?
