There is a list of actions the administration must decide whether to take to keep the marketplaces humming, most of them through regulatory actions at the Health and Human Services Department or through the Internal Revenue Service.
The actions center on three programs: cost-sharing reductions, reinsurance and risk corridors. Cost-sharing refers to government subsidies to low-income Americans to help them pay for insurance. Trump threatened recently to let such subsidies lapse, but Democrats say they will shut down the government as part of the spending negotiations next week if the president follows through.
Incredibly I hadn't come across reinsurance and risk corridors before.
Reinsurance and risk corridors are two programs set up under the ACA to redistribute funds from insurers with healthier enrollees to insurers with sicker, more expensive customers.
New day, learn something new. I wonder if Trump knows anything about them. What am I saying?
