CMS thinking on what Catastrophic plans can do

David Anderson @dmaanderson.bsky.social · 10h

The thinking is fundamentally muddled where Catastrophic plans are to CMS as Tariffs are to Trump

" Since we expanded the bronze de minimis ranges in 2018, enrollment in bronze plans has more than doubled from about 2.5 million to about 5.4 million in 2025.... we seek comment on other potential reasons to explain this phenomenon."

Substantially lower AV #Catastrophic plans are proposed for the #ACA in the #NBPP2027

. Catastrophic Plan Cost-Sharing Requirements Lastly, to best preserve a meaningful difference between the AVs of bronze and catastrophic plans, we propose to amend § 156.155(a)(3) to require catastrophic plans to provide no benefits for any plan year (except as provided in § 156.155(a)(4), (b), and (c)) until an amount equal to 130 percent of the maximum annual limitation on cost sharing, rounded down to the next lowest multiple of 50 dollars, is reached.

P. 227 with monthly limits on cost sharing as an option is creating a massive adverse selection engine especially near OEP in #Catastrophic Plans in #NBPP2027 #ACA

I am glad I am not an actuary

P. 227 Under this proposal, issuers could apply the deductible that applies in the first year of coverage on an annual basis for each year within the coverage, or divide the annual deductible by 12, and apply it equally to each month of the policy throughout the entire term of coverage, similar to how a multi-year plan could choose to apply the annual limitation on cost sharing, as discussed in this section of the rule. For example, if the plan had an annual deductible of $6,000, it could apply 1/12 of that deductible monthly ($500 per month). We seek comment on if, and the degree to which, a plan could modify the amount of the annual deductible for each year of the multi-year policy.

#Catastrophic plans in the #ACA with multiple year terms but annual opt-outs creates some really fascinating (and weird) game theory for enrollees and insurers. Let's minimize game theory

#NBPP2027

Language from p. 226 of the NBPP 2027 Individuals dropping coverage under a multi-year catastrophic plan, either at the end of the term or mid-term, would be treated the same as individuals dropping coverage under a 1year policy either at the end of the year or mid-year, respectively, with respect to open enrollment and special enrollment periods

David Anderson @dmaanderson.bsky.social · 13h

Fair

David Anderson @dmaanderson.bsky.social · 13h

OMG, CMS is all in on multi-year catastrophic plans as an enabler of workplace wellness type plans when the current evidence on that is a very well identified null (p. 223)

Yeah, this is pool splitting

#NBPP2027 is out and P. 221 with 10 year Catastrophic plans Is INTERESTING

I see the health econ justifications as a variance and thus cost reducer, but also a mega pool splitting mechanism with annual opt-outs effectively

My latest, "Free Exercise and the Redistribution of Liberty," is now posted (and forthcoming in @yalelawjournal.bsky.social). It argues that free exercise doctrine uses selective market logic to redistribute both public resources and liberty itself.

Bought this as a vacation read based solely on the cover photo

Has not disappointed

Photo of Greg laying on a beach chair under some coconut trees. In his hand is the book "Starter Villain" by John Scalzi. The cover photo is the top half of an anthropomorphic black and white cat, dressed in a dark suit, white dress shirt, and dark blue tie.
