If someone comes in for a confirm pregnancy visit and a pregnancy test is positive. Can we do the u/s that day for viablitiy, and use code no period. Or can we bring them back in 1 to 2 weeks and do the u/s and still us the code no period? Because I feel that if we know that the patient is pregnant then we must do the nob visit the nest time and use code v22.0 for first pregnancy and v22.1 for 2nd or more pregnancy. Please help me with this questions. thanks
