As a partner practice you do not receive an invoice from us. You receive a credit note (Gutschrift) — money from Aniva to you.
Once a month, for the month before. It arrives in the first days of the new month.
It counts draws, not results. Every blood draw at your practice counts on the day it happened, at your agreed rate per draw. What the lab does afterwards makes no difference.
One document for all your locations. If you run several, they appear as separate lines on the same credit note.
Once issued, it is final. The PDF you receive is the document that gets paid — it is not recalculated later.
Reply to the email before the payment goes out and tell us the patient, the date and the line in question. Correcting it beforehand is much easier than issuing a correction afterwards.
