My Half-Assed MLR Explainer, or How Much Will Be Rebated in 2019 & 2020?

For weeks now, my blog posts have been overwhelmed by my state-by-state analysis of the preliminary 2020 ACA individual market rate filings. With the addition yesterday of Illinois, Hawaii, Iowa, Kansas and especially Florida, I've now accounted for over 75% of the total ACA Individual Market nationally.

I still have a dozen states to go, including large ones like Texas and Georgia, but barring some devastatingly huge rate hikes, the picture is clear: Average unsubsidized 2020 ACA individual market premiums will only be going up an average of less than 1% nationally.

This morning, David Anderson reminded us that, all else being equal, 2020 premiums "should" increase by around 7% on average: 5% for normal "medical trend" (increased cost of medical expenses/claims), plus around 2% to account for the return of the ACA's Carrier Tax (which goes to help pay for the cost of the ACA's subsidies & Medicaid expansion).

Since most Indy Market carriers are turning a decent profit these days, that means, as a general rule, any rate increase short of 7% should indicate that the carrier has fallen below the ACA's 80% Medical Loss Ratio (MLR) rule, and will therefore have to pay a chunk of the premiums back to their enrollees. This isn't true in every case, but it's a pretty good guideline.

Let's go back and review how Medical Loss Ratios work:

  • Under the Affordable Care Act, thanks to a provision included by then Senator Al Franken of Minnesota, insurance carriers are required to spend at least 80 - 85% of their premium revenue on actual medical claims (80% for the Individual and Small Group markets; 85% for the Large Group Market). In this post I'm looking only at the Individual market.
  • If a carrier spends less than 80% on claims in a given year, the difference must be rebated to the policyholders, on a 3-year rolling average.
  • This has resulted in several billion dollars being paid out to millions of ACA enrollees and/or small business owners over the past 8 years (that's right...the MLR rule started out way back in 2011, three years before the ACA exchanges were even up and running!)

Here's how the 3-year rolling average works. Let's say an insurance carrier has exactly 30,000 enrollees each year. Their average unsubsidized premiums started at $278/month in 2014 and increased by 10% in 2015, 14% in 2016, 28% in 2017, 31% in 2018 and then stayed flat for 2019. This isn't too far off from what the trendline has been nationally over the past six years:

Their MLR was way too high the first two years...in fact, they lost money in 2014 and probably in 2015 as well, since administrative overhead/etc. costs more than 5%. Things started to stabilize in 2016, and in 2017 they actually overshot the mark slightly. In 2018 they seriously overpriced, so they instituted a price freeze in 2019 to try and comply with the ACA's 80% MLR rule.

The three-year average for 2014-2016 is nearly 90%, and for 2015-2017 it was still 84%, so they didn't have to pay back any rebates. For 2016-2018, however, they fell slightly below 80% to 79.4%, so they'll have to cut small checks, averaging around $40 apiece, to their enrollees later this year. In 2020, they'll have to send out larger rebate checks for around $110 apiece to each of their enrollees, since their 3-yr average MLR fell another point to 78.4%.

To give you an idea about how much money we're talking about, here's how much was paid out in MLR rebates to Individual market enrollees over the years:

  • 2011: $1.1 billion nationally (breakout not available)
  • 2012: $519 million to 8.8 million people ($59/apiece on average)
  • 2013: $332 million to 6.8 million people ($49/apiece on average)
  • 2014: $469 million to 5.5 million people ($85/apiece on average)
  • 2015: $396 million to 4.8 million people ($82/apiece on average)
  • 2016: $446 million to 4.0 million people ($113/apiece on average)
  • 2017: $706 million to 6.0 million people ($119/apiece on average)

The payments for 2018 (which are sent out in 2019) should be announced within the next month. I expect them to be pretty large.

How large? Well, that's where Anderson's blog post today comes in.

Here's what the above data looks like in table form:

(Note: Kaiser doesn't have the total number receiving rebates or the average enrollee for 2011, but this 2012 article says it was around $160 per household, which suggests perhaps $110 per enrollee for a total of around 10 million enrollees. The total individual market as of 2011 was roughly 11 million people, give or take).

The official average unsubsidized premium for ACA individual market policies in 2019 is around $600/month per enrollee, although that usually ends up being a bit lower in practice since the official average assumes that 100% of enrollees stick with the exact same policy they're currently enrolled in. In practice, millions of people shop around each year (as they should) for better deals, lowering the effective average premium a bit.

If you're wondering how hundreds of millions could be paid out in previous years even with MLRs over 80%, remember that this is the national average. Every year, some carriers fell below 80%, even in 2015 when the national average was a whopping 103%.

In 2017, over $700 million was paid out even though the 3-year rolling average was 93.7% nationally. In 2018, the 3-year average dropped by a whopping 10 percentage points, which almost certainly means a huge increase in MLR payments going out this year. And for 2019?

Well, we don't know what the full-year MLR is going to be for 2019, but we do know what it was for the first quarter of the year: It moved back up from 68% in 2018 to 73%. Assuming that same 5-point increase holds true for the full year, it should average around 75% for 2019. If so, that will result in a 3-year rolling average of just 75.7%...another 7 points lower than 2018.

Seven points. Which happens to be almost exactly the difference between Anderson's 7% rule of thumb and the 0.5% national average rate increases expected so far.

Based on the Kaiser Family Foundation's data, it looks like the actual average being paid in 2019 will end up being more like $575/month. That's $6,900/year. Assuming an average of around 13.5 million effectuated enrollees in the ACA market per month, that's a total of roughly $93.2 billion in premiums.

If you use Anderson's 7% and assume the final, national weighted average for 2020 comes in at around 0.5%, that means roughly 6.5% of that $93.2 billion could end up having to be rebated to enrollees....or potentially up to $6 billion.

In theory, if you were to divide that by all 13.5 million enrollees, it would average $444 apiece, or nearly 4x as much as the highest rebate average to date. In reality, not all 13.5 million will receive rebate checks, and there's no way of knowing exactly what the total payout will end up being. Even if it does turn out to be exactly $6 billion, the amount paid out in a given year will be skewed by the 3-year rolling average factor. The amounts will vary widely from carrier to carrier, and not every carrier will have to pay out rebates at all, while others could potentially be much higher.

Remember, the whole point of the program is to encourage carriers not to price gouge by keeping their premiums, and therefore their profit margins, within a limited range. I've been enrolled in an ACA exchange plan since 2014 and I've never received a rebate check yet, though I do know a few people who have. Having said that, I wouldn't be surprised to see MLR rebates averaging $250 or higher this year...and possibly $400 or higher next year. For some people it could hit up to $1,000 or more. Anything's possible.
