The PA Department of Human Services says the following:

Starting April 1, 2023, if you get your health insurance from the state, you will need to complete your renewal every year when it is due to make sure you are still eligible to receive Medicaid or CHIP.

You will not automatically [or immediately] lose health coverage.

No one will lose their health coverage without having a chance to complete a renewal or update their information. But, if you do not return your renewal when it is due, you may risk losing your coverage.

To check  your renewal date or submit your renewal online, here's the link they offer:https://www.compass.state.pa.us/compass.web/Public/CMPHome
