For benefits with a special waiting period of eight months, the rule is: the start of the contract should be at least eight months before the planned treatment. If you are planning dentures or expecting a baby, you must bring the start of the contract forward accordingly.
Poor planning at this point means that exactly the benefits for which the switch would be most worthwhile fall into the waiting period. This is especially annoying for expensive dentures.
From our advice work, we recommend a transition plan with a buffer of at least four weeks before procedures that can be planned. What matters is to clarify the crediting of the waiting period in writing and to set the start of the contract deliberately eight months before the planned treatment.
