S3620
Our lab in the hospital does a capillary collection for PKU testing for infants not born at our hospital and then sends it to the State for the newborn screening tests. We are charged a set amount of $ for each card from the State. The lab wants to set up a charge so we can submit the claims. After my research, it appears hospitals are using S3620 for outpatient claims with rev code 300. We would also charge for the capillary collection. I was wondering if we need to add modifier 90 because we are not doing the actual PKU lab. Any advice would be greatly appreciated
