2027 Rate Changes

Originally posted 8/28/26

ACA exchange enrollment has dropped by more than 10% in Florida since Congressional Republicans allowed the enhanced federal subsidies to expire at the end of last year.

Initial signups during Open Enrollment were only down 4% vs. OEP 2025...but effectuated enrollment was 7.7% lower year over year in January, rising to 10.3% lower as of February.

That's over 440,000 Floridians who already lost healthcare coverage in just the first two months of the year...a number which has likely continued to climb since then.

When I last updated my "coverage loss" estimate a couple of weeks back, I noted that while I have hard effectuated enrollment data for Medicare and Medicaid as well as the CHIP and BHP programs, my estimates for ACA exchange enrollment have to rely on rough projections because:

...I could eliminate (or at least vastly narrow) the upper/lower bound estimates if CMS would actually update the actual Health Insurance Exchanges Monthly Effectuated Enrollment database, which is supposed to be updated monthly but which has been stuck at February 2026 for the past four months...

ACA exchange enrollment has dropped by nearly 30% in South Carolina since Congressional Republicans allowed the enhanced federal subsidies to expire at the end of last year.

Initial signups during Open Enrollment were only down 7% vs. OEP 2025...but effectuated enrollment plummeted by 14% in January and a whopping 29.1% as of February vs. a year earlier.

That's nearly 160,000 South Carolina residents who lost coverage in just the first two months of the year...a number which has likely continued to climb since then.

Idaho is one of a handful of states where plan selections during the 2026 Open Enrollment Period actually increased year over year, by around 2.6%, in spite of the enhanced federal subsidies expiring back in December.

Two months into the year, however, effectuated enrollment is actually down slightly (by around 2.2%, or roughly 2,500 enrollees).

Here's what this looks like visually, with both 2025 and 2019 (the last pre-COVID year, which didn't include the enhanced subsidies) included for comparison:

Individual Market Proposed Average Rate Changes for Plan Year 2027 

The summary table below provides an overview of the proposed average rate changes from 2026 in the individual health insurance market, as reported by the insurers.  

It is important to note these are the initial rates proposed by the insurers and filed with the Departments. Rates are subject to review and approval by the Departments, and the final approved rates may vary from these proposed rates for many reasons.  

Additionally, the actual rate change a consumer will experience in 2027 can vary from the average – with factors such as specific plan, geographic rating area, and age playing a major role.
