Can my Health Insurance Plan be Discontinued if I get it from the Healthcare Exchange?

Hello Reddit,

I’m considering switching from a costly, grandfathered BCBSIL PPO health insurance plan to a potentially more affordable option on the Health Care Exchange, possibly an Aetna PPO. My primary concern is maintaining access to a wide provider network at major Chicago hospitals due to my having multiple health problems . Here are my key questions:

(1) If I opt for a new plan like Aetna PPO and, in the future, Aetna changes or discontinues their PPO plans with extensive networks, what are my options? Are there any Illinois or federal laws that protect my coverage in such scenarios?

(2) The reason for my concern is because I found out after researching that eight years ago, BCBSIL discontinued certain PPO plans from the Healthcare Exchange, as detailed in this thread:

This situation is a major part of my concern. I wonder if those who had these BCBSIL PPO plans from the Healthcare Exchange before the discontinuation got to keep their health plans because of certain laws or regulations?

I’m trying to gauge the risks of leaving my current plan and what protections State or Federal, if any, are in place for keeping plans from the Healthcare Exchange in the case they get discontinued.Any advice or shared experiences would be greatly appreciated.

Thank you!
