The question kit
Check an offer, one question at a time.
Use the cards that fill the gaps in an offer you already found. Write down what is clear, what needs proof and what still has no answer.
Check who is involved
Write down three names: the service arranging your care, the person treating you, and the pharmacy supplying your medicine. Ask whether that pharmacy also makes the medicine or gets it from another maker.
Prepare for the care
Move from the offer to the actual visit. Ask how questions, records and later contact will work.
Pin down the offer
A clear quote and a clear product name give you something concrete to compare.
