Hello,
I went to the Frankfurt clinic for the medical and wanted to update the available information.
I specified I was a Ukrainian applicant. As of late June, they take payment via card only (American Express doesn't work for them it seems, so keep mind if that's the case for you). I paid 390 euros for the doctor's exam part, and will be sent a separate invoice for lab tests. I was told it's supposed to be 16 euros. I'm staying at an airbnb so I requested to send it electronically, they assured me it's not a problem and wrote down my email. So far I haven't received it.
Another thing is, US Immigration added Hepatitis B to the obligatory vaccinations list. They offered me to get the first shot during the medical for ~70 euros, but I opted to do that in the US. Now a little off-topic about Hep B - there's a standard scheme with 3 spaced out shots, which takes 4-6 months to complete. And then there's Heplisav-B, which is 2 doses within 1 month. It's FDA approved. It's also available in the EU if you prefer to get your shots here.
Hope this helps!
