- Claims for care received before the end date can still be processed. Ask how to submit them after you cancel.

Cancelling a health insurance plan
Health plans end on set dates and often cover a whole household, so the request has to name the plan, every person on it and the date cover should stop, with new cover lined up first.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
