When I did a cycle going over one year (AF started in December/transfer in January) two years ago, Medicare determined the date for the cycle was the day your cycle commenced (AF start date), not the day of transfer that counted. Hope this helps - it certainly makes it easier as you know exactly before you start! It might have changed since then, but from memory, they were actually consolidating it as it used to be different for different types of cycles and the lady at Medicare told me this was to make it easier and ensure there wasn't pressure from the patients or clinics to do a transfer before they should in order to fit the medicare date into the previous year.
