Advice on health insurance claims.

I had two insurances, I was primary on both. I have insurance 1 from 2016 till now except in 2022. I had Insurance 2 from Nov 2019 until Aug 2023, when I quit working there.

I used only insurance 2 for the services I recieved from 2021 to Aug 2023. I know I made a mistake not using both insurances, I didn't know at the time it would create problems.

Around April/May 2024, I started getting mails from insurance 2 denying claims for the bills they paid in 2022 and 2023. I haven't yet received similar mails for the 2021 claims.

My questions are 1. I dropped insurance 1 in 2022. Since I only have insurance 2 in 2022, can insurance 2 deny the claims for the bills they paid for 2022? 2. In 2023, I had both insurances till Aug 2023. After Aug 2023, I only have insurance 1. Which insurance will be the primary for 2023 till August ? If insurance 2 is the primary, can they deny the claims for the bills they paid for 2023 ?

Thanks in advance for any help
