How do you cancel your health insurance correctly?
A clean change is primarily a process issue. The deadline alone is not enough if information is missing, the new fund has not yet been confirmed or the letter arrives too late.
Step-by-step instructions
- Compare offers and decide whether you only want to change the basic insurance or also supplementary insurance.
- Choose new basic insurance and first wait for written acceptance of supplementary insurance.
- Write a cancellation with your name, address, policy number, type of insurance affected and desired end date.
- Send letters by registered mail or A-Post Plus in good time so that receipt can be verified.
- Check the confirmation and start date of the new insurance and keep all documents.
Cancellation checklist
The cancellation includes at least your name, your address, your policy number, the insurance company concerned, the desired cancellation date and your signature. In the case of family policies, it should also be clear which person or which part of the contract is being terminated.
What documents should you keep?
- Copy of the termination letter
- Proof of posting or delivery
- Confirmation of previous health insurance
- Policy or confirmation of acceptance of the new insurance
Which errors block the change?
Many changes fail not because of intent, but because of operational errors. Especially in 2026, you should clearly separate deadlines, type of contract and outstanding claims.
- Sent too late:The termination only occurs after the deadline and the contract continues.
- supplementary insurance canceled too early:The new policy is not yet confirmed or contains unexpected exclusions.
- Type of insurance not clearly stated:The letter does not make it clear whether basic insurance, supplementary insurance or both should be canceled.
- Open rewards or costs:Residues can make the change difficult or block it.
- Model and deductible not taken into account:The supposedly cheapest health insurance fund does not match your service needs or your switching goals.
Important
Price alone is not enough as a basis for decision-making. Especially with basic insurance, in 2026 you will also have to look at the model, deductible, region and the actual termination date together.
