If we do an ultrasound to rule out breech presentation and also to evaluate low amniotic fluid, should we code both a limited ultrasound and a follow-up ultrasound modified by-51 (multiple procedure) or -59 (distinct procedure)?
A
If you are reevaluating a previously documented problem (the low amniotic fluid) and then discover or evaluate the possibility of a new one (the breech), you should be reporting only 1 code—the one with the highest relative value.
