In an effort to stabilize the Exchanges and encourage issuer participation, the Centers for Medicare & Medicaid Services (CMS) recently extended the federal Exchange application and rate filing deadlines and published a proposed rule affecting the individual health insurance market and the Exchanges. While issuers will likely see these actions as encouraging signs of the Trump administration’s willingness to support the Exchanges, these actions do not resolve the political uncertainty regarding the Affordable Care Act’s fate or whether cost-sharing reductions will be funded for 2018. These outstanding questions will likely be a key factor in Exchange stability going forward.
