We just started getting EOB's for BCBS and UHC not waiving co-pays for positive Covid 19 (U07.1) patient's office visits. Up until now. If a patient was seen and tested for Covid. We used the CS modifer with U07.1 (if positive) and Z20.828 if exposed. All of a sudden they are not waiving the copays if we use the U07.1 diagnosis. I have scoured their web sites. Is anyone else having this happen?? Thank you.
