Billions in ACA rebates show 80/20 Rule’s impact

Medical loss ratio forced carriers to devote more premium dollars to care, and record-high rebates were issued in 2019 and again in 2020

The Affordable Care Act's medical loss ratio has delivered nearly $5.3 billion in premium refunds to American consumers since 2012.

In the 9th year of MLR rebates, the rebate checks in 2020 are larger than they’ve ever been, driven mostly by the individual insurance market

Ever since 2012, millions of Americans have received rebates from their health insurers each fall, refunding portions of prior-year premiums that were essentially too high.

It’s all thanks to the Affordable Care Act’s medical loss ratio (MLR) — a provision sponsored by Minnesota’s former Senator, Al Franken — that forces health insurance companies to use your premium dollars to provide actual health care and quality improvements for plan participants, or return that money to you. In 2020, insurers were required to pay nearly $2.5 billion in rebates to more than 11 million consumers. That was based on insurer revenue and spending for 2017-2019, and it was the highest total amount since the MLR rebate program began. That came on the heels of the $1.37 billion in rebates that insurers sent to nearly 9 million consumers in 2019, which had also been a record high at that point.

Rebate checks were first sent to consumers in 2012, and totaled $1.1 billion that year (this was based on performance in 2011, before the bulk of the ACA’s provisions had taken effect; the individual market was still medically underwritten in nearly every state at that point).

Rebate totals were smaller over the next several years, but spiked sharply in 2019 and 2020, driven in large part by the individual market. The individual market only covers about 6 percent of the US population, but it’s a volatile market and premiums increased drastically in 2017 and 2018, leading to significant insurer profits starting in 2018. Of the consumers who received rebates in 2019, more than 41 percent had individual market coverage. And 46 percent of the consumers receiving rebates in 2020 had individual market coverage; their rebates amounted to nearly 70 percent of the total amount that insurers sent in rebates in 2020 (more than $1.7 billion of the $2.5 billion that insurers sent to consumers went to people who had individual market coverage).

For perspective, about 19 percent of the total amount that was rebated to consumers in 2018 was for individual market coverage, but the continued sharp increases in premiums in 2018 pushed profitability considerably higher and has resulted in a much larger total MLR rebate amount for individual market consumers in 2019.

Including the rebates issued in the fall of 2020, total rebates issued from 2012 through 2020 amount to nearly $7.8 billion. The rebates issued in the fall of 2020 were based on insurers’ MLR performance across 2017, 2018, and 2019. Premiums in the individual market spiked in 2017 and again in 2018, and based on the MLR data, it appears they were set too high by 2018. They have been much more stable for 2019, 2020, and 2021, but the MLR rebates continue to be very large due to the three-year rolling average calculation and the fact that rates are still mostly in the same ballpark region as 2018.

To clarify, the goal is to have insurers spending the majority of your premium dollars on medical claims so that rebates aren’t necessary. But given that insurers set premiums a year in advance, it’s not always possible to accurately project membership (and thus revenue) and claims costs. So the rebates serve as a backstop, ensuring that even if premiums are ultimately set too high in a given year, the MLR rules still apply.

Rebates vary by state and by insurer

Although total rebates were far larger in the fall of 2020 than they had ever been, most people didn’t receive a rebate check at all, since most insurers tend to be in compliance with the MLR requirements. Every year, there are some states where no rebates are issued (ie, all of the insurers in that state hit the MLR targets; this was the case in seven states in 2019, but only four in 2020), and even in states where MLR rebates are issued, they’re usually only sent out by a few insurers.

In 2018, almost 6 million people received rebates (including the individual, small group, and large group markets). The largest average rebates were in Minnesota that year, where more than 41,000 consumers received average rebates of $479 each. Nationwide, the average rebate check was $119.

But in 2019, nearly 9 million people received rebates, and the average rebate check was $154 (it averaged $208 for the 3.7 million people who received an MLR rebate based on individual market coverage). The largest average rebate checks were sent in Kansas, where about 25,000 people received rebates that averaged $1,081.

And in 2020, the average rebate check grew to $219. The largest average rebate checks were again sent in Kansas, where more than 40,000 people received rebates that averaged $611.

For subsidized enrollees, rebate amounts can exceed net premiums

MLR rebates are paid to policyholders. In the case of employer-sponsored plans, the rebates are sent to the employer (who can pass them on to employees or use the money to reduce employees’ future premiums or provide enhanced benefits). And in the case of individual market plans, the rebate is sent to the individual who purchased the plan. And the rebate amount is based on the full cost of the plan, regardless of how much of that cost was offset by a premium subsidy.

Premium subsidies became disproportionately large in 2018, due to the way insurers handled the cost of cost-sharing reductions (CSR). That resulted in a sharp uptick in the number of individual market enrollees who paid very low premiums, or no premiums at all, for bronze plans, and even gold plans in some areas.

But if a plan has to send out MLR rebate checks, the checks are based on a percentage of the full cost of the plan. And the full amount of the rebate is sent to the enrollee — it’s not sent to the US treasury, even though that might have been who paid the bulk of the premiums via premium subsidies. Dave Anderson and Charles Gaba both have excellent explainers about this.

The short story is that the rebate amounts might not seem “fair” at all. A person who paid very little in after-subsidy premiums might receive a significant rebate check, while their neighbor might receive no rebate check at all — even if they weren’t eligible for a subsidy and had to pay what seemed an exorbitant monthly premium — because they were enrolled in a plan that met the MLR requirements. To reiterate, most Americans do not receive a rebate check (keep in mind that even with the record-setting rebates that were sent out in 2020, only about 11.2 million people received rebates, which is still a very small chunk of the U.S. population). And the relative affordability of a person’s premiums has little to no bearing on whether they’ll end up receiving a rebate check.

Rebates? What rebates? How do they work?

The rebates are tied to the medical loss ratio: the percentage of insurance premium dollars spent on actual health care – as opposed to marketing, profits, CEO salaries, and other administrative expenses. If an insurer spends less than 80 percent of individual and small-group plan premiums (85 percent for large-group plans) on providing medical care, they must rebate the excess dollars back to plan members and employers via checks that are sent to consumers each fall.

MLR rebates are calculated at the insurer level for each of the three market segments (individual, small group, and large group), and on a state-by-state basis. An insurer’s aggregate numbers in each of those markets are considered to determine whether rebates are necessary. If they are, they apply to everyone who had coverage under that insurer’s plans in that market segment in that state — it’s not broken down on a plan-by-plan basis beyond that. However, the exact amount of each policyholder’s rebate is based on the (pre-subsidy) premiums for the plan that person had.

So if an insurer offers several different plans in the individual market and the aggregate MLR across all of those plans is under 80 percent, the insurer is going to owe rebates to everyone enrolled in those plans. But people with higher-priced plans (including older people, people who selected richer-benefit coverage, and people in higher-priced areas of the state) are going to get larger rebates than people with lower-priced plans, since the rebate is calculated as a percentage of the premium.

The majority of very large employers self-insure their employees’ health coverage, and MLR rules do not apply to self-insured plans. There were also initially exemptions for non-profit insurers, although they had to begin complying with the MLR requirements in 2014. Some states received CMS approval to modify MLR requirements within the state in the early years, but there are no longer any states with MLR requirements that are lower than the federal rules (Massachusetts has a much higher MLR requirement, at 88 percent for individual and small group plans; New York’s is 82 percent).

Although the MLR rules are an important regulatory tool, the majority of insureds do not receive a rebate check, as most insurers’ administrative costs are less than the allowable amount. About 11.2 million people received rebates in 2019, which is only a little more than 3 percent of the population.

Rebates are based on a 3-year average MLR

The rebates that are sent out each fall are based on the average MLR for the prior three years. The rebates that were sent out in 2020 were based on each carrier’s average MLR for 2017 – 2019.

The total rebates sent out on 2020 and 2019 have been the largest and second-largest to date. Prior to 2019, the largest total rebates had been sent in 2012, as that was the first year that rebates were sent to consumers and insurers were still fine-tuning their revenues and expenses to comply with the ACA’s new rules. But the total rebates sent out in 2019 were higher than they had ever been, and then the rebates that were sent in 2020 dwarfed the 2019 amount, exceeding it by more than a billion dollars.

And while the number of states where no rebates are necessary at all had been steadily rising for the last few years, reaching 11 in 2017 (an indication that more insurers were right-sizing their premiums), it dropped to seven in 2018 and 2019, and then dropped to just four (Rhode Island, North Dakota, West Virginia, and Wyoming) in 2020. Although the individual market was the primary driver for the spike in total rebates in 2019 and again in 2020, there were 15 states where no rebates were sent to individual market enrollees in 2019, and there were no individual market MLR rebates sent in 2020 in eight states plus DC.

Most people don’t get a rebate check, because most insurers are spending the majority of premiums on medical costs

Across all market segments, the majority of insurers have been meeting or exceeding the MLR rules, which is why most people don’t receive MLR rebate checks (this continues to be the case, even with the record-high rebates in 2020, but an increasing number of individual market enrollees have been in plans that aren’t hitting the MLR targets in recent years, as we’ll discuss in a moment). According to the data that was calculated in 2017 (for plan years 2014-2016), the average individual market MLR was 92.9 percent and the average small group MLR was 86.1 percent (both well above the 80 percent minimum requirement).

In the large-group market, the average MLR was 90.3 percent, also well above the 85 percent minimum requirement for that market segment. For all three market segments, the average MLR reported for 2017 was the highest it had ever been.

HHS also reported at that point that the vast majority of insurers are enrolled in plans that are meeting the MLR requirements. For the MLR reporting in 2017 (based on 2014-2016 MLR numbers), 95 percent of individual market enrollees were in plans that met the MLR rules – so only 5 percent of individual market enrollees ended up getting rebate checks in 2017 (this was an improvement from 2011, when about 83 percent of individual market enrollees were in plans that met the MLR requirements).

But obviously, that has changed quite a bit in the last few years; there were 3.7 million individual market enrollees who received MLR rebates in 2019, which amounts to about 30 percent of the roughly 12 million people enrolled in ACA-compliant individual market plans. And in 2020, for rebates based on the 2017-2019 plan years, almost 5.2 million individual market enrollees received MLR rebates, amounting to well over four out of every ten individual market enrollees.

Premiums in the individual market only increased slightly for 2019, despite some significant upheaval in the market (elimination of the individual mandate penalty, along with the expansion of short-term plans and association health plans). They barely changed at all for 2020, and are again changing very little for 2021. That’s an indication that premiums were certainly adequate in 2018, and possibly too high in some cases (the expectation is that without the aforementioned market upheaval, average rates would have decreased for 2019).

Loss ratios have dropped as insurers regained profitability in the individual market (thanks to large rate increases in 2017 and 2018), and this is the driving factor behind the much larger MLR rebates in 2019 and 2020. But the majority of individual market enrollees are still in plans that are hitting the MLR targets, despite the sharp rate increases in 2017 and 2018. It remains to be seen how this will play out over the next few MLR cycles, given the impact of the COVID pandemic on insurer costs: As elective procedures were postponed or cancelled in 2020, insurer costs dropped considerably for a while. But the ongoing impact of the pandemic on insurers MLRs is uncertain, to say the least.

Total rebate amounts so far have been:

In 2020, more than 11.2 million consumers received rebates that averaged $219. (The average was $332 in the individual market, $124 in the small-group market, and $121 in the large-group market; rebates in the group market are sent to employers, who then have options for how to use the money.)

The highest average rebates among consumers that received them in 2020 were in Kansas (for the second year in a row), where average rebates were $611 – almost three times as much as the national average, but considerably lower than the average rebates of $1,081 that were sent in Kansas in 2019. And average rebates in Kansas in 2018 were only $157, illustrating how much the market can change from one year to another based on premiums and total claims.

In four states, North Dakota, Rhode Island, West Virginia, and Wyoming, there were no MLR rebates necessary in 2020, because all of the individual, small group, and large group insurers met the MLR requirements.

Wyoming has had no MLR rebates for five years in a row (2016, 2017, 2018, 2019, and 2020), because all insurers offering coverage in the state have met the MLR requirements each year. But it’s worth noting that Wyoming had the highest average MLR rebates in 2015, and Hawaii, which had no rebates in 2017, had the highest average rebates in 2016 and the second-highest average rebates in 2018. In small markets like Wyoming and Hawaii, a few expensive claims can have a very significant impact on MLR numbers.

So although nobody received a rebate check in four states in 2020, that’s a good thing — it means that all of the insurers in those states spent at least 80 percent (at least 85 percent for large group plans) of premiums on medical claims and quality improvements, as opposed to administrative costs. [You can think of this as similar to a tax refund: People certainly like receiving a tax refund, but the ideal scenario is to not overpay your taxes during the year, since that just gives the IRS an interest-free loan.]

But in most states, at least some consumers received rebate checks in 2020, as had been the case in prior years. Here are the data for the rebates that insurers sent out in the fall of 2020:

GOP tried unsuccessfully to repeal the federal MLR rules in 2017, and GOP-led states are seeking to get rid of the MLR rules (and the rest of the ACA) in the court system

While the MLR provision has obvious appeal to consumers, it isn’t universally loved – and was among the ACA provisions in Republicans’ crosshairs as they attempted to repeal the ACA in 2017. The Senate’s 2017 Better Care Reconciliation Act (BCRA) would have eliminated the federal requirement that insurers spend the majority of premiums on health care. (That measure did not pass the Senate when it was introduced as a substitute for H.R. 1628 in July 2017.)

Under the BCRA, states would have become responsible for the regulation of insurers’ administrative costs. This is similar to the approach that the Trump Administration has taken with regards to insurers’ network adequacy, and it’s in keeping with the GOP belief that regulatory authority should be concentrated at the state – rather than federal – level.

The Congressional Budget Office estimated that about half the U.S. population lives in states where the current federal MLR rules would have been maintained if the BCRA had been implemented, and the other half live in states where the rules would have been relaxed. “Relaxed” rules would have led to increased premiums (and of course, smaller MLR rebates), particularly for people who don’t qualify for premium subsidies in the exchange. [As noted above, individual market rebates are sent to the policyholders, even if the bulk of their premiums were paid by the federal government via subsidies. But without an MLR requirement, insurers would be able to charge higher prices without having to worry about future rebates, and consumers who don’t qualify for subsidies would be hardest hit.]

GOP efforts to repeal the ACA in 2017 were not successful, though, so insurers in every state still have to spend the majority of your premium dollars on medical costs and quality improvements, rather than administrative expenses. The Supreme Court is expected to rule in 2021 in a case that seeks to overturn the ACA, and although the oral arguments indicated that the law is likely to be upheld by the Court, nothing is certain yet. If the ACA were to be overturned by the Supreme Court, the MLR rules would no longer apply, and insuers would no longer have to send rebates if they spend more of their premium revenue on administrative costs and less on providing health care.

This discussion of rebates and MLR is one-sided and biased, for two reasons. First, if a law requires one group of companies — IN THIS CASE INSURERS — to pay rebates, how much are those companies getting from the federal government in SUBSIDIES which we all pay for in HIGHER INCOME TAXES? Second, if a law requires one group of companies — IN THIS CASE INSURERS — to pay rebates, how much are those companies getting from consumers in higher premiums, so that they can turn around and “pay” a rebate? Once both of these issues are quantified, the rebates will likely be canceled out and probably NEGATIVE!!!

The subsidies are incorporated into the total premiums — they are not in addition to the total premiums. The rebate amounts are calculated based on the total premiums, but the entire rebate is sent to the enrollee, as opposed to being split between the government (for the subsidy portion) and the enrollee (for the after-subsidy portion of the premium). So it is possible for a person to get a significant rebate even if they didn’t pay much in after-subsidy premiums. This could be remedied if GOP lawmakers were willing to work on fixing the ACA as opposed to only wanting to tear it down.
But to your second point, that’s the whole point of the rebates. They’re designed to ensure that if insurance companies charge premiums that are too high, they end up paying back the excess. This, together with the rate review process conducted by state and federal actuaries, helps to ensure that over time, insurance companies cannot have excessive administrative costs, including profits.
What we really need is something similar to the MLR rule for other portions of the health care industry, including pharmaceutical companies, medical device manufacturers, and hospitals.

Your response to Arthur’s second point is off the mark. What he means is that MLR incentivizes year-over-year premium increases, as that is the only way for insurance companies to increase their profits. Therefore, insurance companies are incentivized to pay for the most expensive care possible, even if it doesn’t improve outcomes. Think excessive tests, scans, lab work, etc that have no medical benefit, yet increases the cost of care, which legally allows them to charge more, and therefore profit more.

This Huffington Post article explains this “perverse incentive” well:

Is this rebate considered taxable income?

Reply to  William

The general rule of thumb is that if the health insurance premiums were paid with after-tax dollars (ie, you didn’t deduct them on your tax return), the MLR rebate is not subject to income tax.
But if you paid your premiums with pre-tax dollars, the MLR rebate is subject to income tax. So for example, the MLR rebate would be taxable in the case of a self-employed person who deducts their premiums, or a person who itemizes and deducts premiums as part of their medical expenses. Here’s more from the IRS:

What can I do when ambetter refuses to send my refund check for medical loss ratio? I Requested it NOT be applied as credit for my premium because I did not want to mess up my auto pay. I have contacted them 3 times and they say it is being processed. I thought by law they had to send it by September 30.
I am so tired of them lying to me!

If Ambetter has confirmed that you’re owed a rebate and they still haven’t sent it, you could try contacting the insurance department in your state:
The insurance department is responsible for overseeing and regulating health insurance companies, and they may be able to step in on your behalf or point you in the right direction.

The checks that were sent out in 2020 were for the 2017-2019 MLR cycle. The ones for 2016-2018 were sent out in 2019. This is the list of insurers that owed rebates for 2018 (paid in 2019):
If you never received yours and your insurer is on that list (be sure it’s the right market: individual vs. small group vs. large group), you can contact your insurer directly, or your state’s department of insurance.

Greetings, I just received my Ambetter rebate check for 2020. They had to rebate 8.8%. My 1095a shows total premiums of $7,760. Why did I receive a check for less than 100 dollars ? Should it have been 8.8% x $7,760=$683 ? Much thanks in advance.

Did your insurer offer any sort of premium relief last year, tied to COVID? Many insurers offered “premium holidays” during the year, which would reduce MLR rebates. But if the insurer prepaid any of the rebate, I would expect that they would note that in the letter they sent you along with your rebate check.

Otherwise, your best bet is to contact the insurer and/or your state department of insurance to get clarification on the amount that should have been rebated to you.

Hi Louise, Ambetter did not offer any premium relief tied to Covid last year. I did get an Ambetter rebate check last year (for 2019) but I don’t think that should matter for 2020. When I wrote to them about the current rebate check I received this reply, which seems meaningless: “We have reviewed of your Medical Loss Ratio Rebate. After review, the Medical Loss Ratio Rebate requires health insurers to spend at least 80% of the money we take in on premiums on health care and quality improvement activities instead of administrative, overhead, and marketing costs. This means that we almost met the Medical Loss Rebate target for 2020. The amount may be lower than the 80% of your premium depending on rebates for all of the states premiums and claims for group policies issued by Ambetter from Home State Health in Missouri for the previous calendar year. Rebates are not based only your individual policy, claims and premiums. We apologize for the confusion.”

If they didn’t provide any premium relief last year, I can’t think of a simple explanation for why your rebate isn’t 8.8% of your plan’s total premiums. I would advise following up with them to see if someone can clarify exactly how they arrived at the amount of your rebate check. It’s possible that their initial communication was incorrect, and that their MLR was closer to the 80% target than they initially indicated (based on their wording of “we almost met the MLR target for 2020”).

Would love your thoughts, please comment.x
