I've been on 10,000 IU daily for longer than that, its the only thing that brought me up into the normal range, and my doctor just does periodic blood tests (for either it going high or any signs of the problems that can come from it being too high) and has it listed with my current medication in my chart.
The miscommunication seems to be in her care team: symptoms associated with high vitamin D occurred, she was known to be on a high supplemental dose, but it was months of progressively worsening symptoms before anyone put 2 and 2 together.
Vitamin D seems less of the issue here than sharing and/or appropriately considering medical records
I take 12k IU of D3 + K2 to keep my calcium and vitamin D levels adequate.
Also, I have anemia of unknown etiology.
Not recommended for everyone, but supplementation should be calibrated with regular blood tests. This should be the standard of maintaining homeostasis.
