Every case is different, and you should contact your insurer to see if you can carryover any payments you have made towards your deductible and out-of-pocket maximums to your new Pennie plan.
Some insurers are allowing their off-exchange enrollees to carryover these payments to their comparable Pennie plan so their enrollees can take advantage of the new savings available under the American Rescue Plan (ARP). Your insurer can help you understand the comparable Pennie plan available to you, and if you can carryover any payments you have made to that plan.
