The entire point of the telemedicine (particularly in the pandemic) was to give women access to healthcare remotely. Abortion is healthcare.
I don't believe a face to face abortion appointment would involve a scan. AFAIK, there is no other way of telling the gestation of a pregnancy. Certainly antenatal appointments simply ask questions about last menstrual period and date from there, unless a scan (which doesn't happen until 12 weeks at the earliest) indicates that this is likely to be incorrect.
(I had one EDD changed post scan, which was annoying as I knew when my LMP was, and I was more right than the scan when it came to the birth)
