Congress is Fighting Over Medicare Dental. Either Way, Your Reimbursement Sucks.

Congress has put a number on your senior patients' mouths, and it's $238 billion over ten years. That's the Congressional Budget Office's estimate for a universal Medicare dental benefit, according to KFF Health News, and it is not a windfall headed for your operatory. A federal dental benefit isn't new money for your practice; it's a discount card handed to the patients who already pay you in full.

Here's our view, and an informed owner can absolutely argue with it: whichever version of a Medicare dental benefit eventually passes, it will cut what your existing senior patients are worth, and the practices that come out ahead will be the ones that repriced the senior cohort before the fee schedule existed. The optimistic case is that a benefit brings in the millions of seniors who currently avoid the chair. That case is real. It's also a volume argument, and volume arguments only work if you have the chair hours to absorb them at a lower rate. Most of you don't.

$238 Billion Sounds Enormous Until You Divide It

Run the arithmetic on CBO's number. Spread across ten years, a universal benefit costs roughly $23.8 billion a year.

If something like 60 million beneficiaries qualify, that's about $397 of federal spending per beneficiary per year, and that figure includes the government's administrative overhead, not just what lands in your bank account.

Four hundred dollars a year buys two prophies, two exams and a bitewing series at fees a lot of you would consider light. It does not buy a crown. It does not buy a denture, even though S. 5089, the Medicare Dental Benefit Act of 2026, promises prostheses alongside diagnostic, preventive, basic, major and emergency services. Sponsored by Sen. Angela Alsobrooks with Sens. Blumenthal and Merkley, introduced July 22, 2026, and sitting in Senate Finance, that bill describes a generous benefit. CBO's price tag describes a modest one. Something has to give, and the thing that gives in every program like this is the fee schedule.

What Medicare Actually Pays For Today, and the Modifier That Gates It

Right now Medicare excludes dental care by statute. Section 1862(a)(12) of the Social Security Act is the exclusion, and CMS keeps a narrow list of exceptions where dental work is "inextricably linked" to a covered medical service: organ transplant, cardiac valve replacement, head and neck cancer treatment, dialysis. Since July 1, 2025, billing those exceptions requires the KX modifier plus a supporting ICD-10 code.

That's worth knowing operationally, because it's the only Medicare dental money that exists today and most practices never bill it. If you clear patients before transplant or radiation and you're writing those extractions off as community service, stop. Build the KX workflow. It's a small revenue line and a real one.

But it is not the thing Congress is fighting about, and it is not the thing that will change your margins.

The Medicaid Tape Already Played This Movie

You don't have to speculate about what a government dental fee schedule does to a practice, because the country already ran the experiment. Per ADA News, citing Health Policy Institute data, Medicaid fee-for-service reimbursement in most states sits far below 50% of dentist charges and below 60% of what private insurance pays. The result: 41% of U.S. dentists participated in Medicaid or CHIP as of 2024, exactly where participation stood in 2015. Nine years, no movement.

And raising the rates doesn't fix it cheaply. The NBER working paper by Buchmueller, Orzol and Shore-Sheppard found that higher Medicaid fees do increase the share of dentists treating Medicaid patients and do modestly raise use, but at a very high incremental cost per additional visit. Translation for the person signing the payroll: the government has to spend an enormous amount to buy a small amount of additional access, which means it won't, which means the rate stays low.

That pattern is the cleanest example of Drift vs. Erosion in American dentistry. A rate that's flat for a decade against rising wages, lab fees and rent isn't drifting. It's eroding, structurally, and no amount of scheduling discipline recovers it. Owners who spent 2015 to 2024 trying to operate their way out of Medicaid economics learned that the hard way. A Medicare dental schedule built by the same budget process deserves the same classification on day one.

Your 420 Senior Patients Are Worth $175,560 Less

Make it concrete. Say you have 420 active patients over 65, and today they average $760 a year in net collections each, because most of them have no dental coverage and pay your full fee, or carry a thin retiree plan you're out of network with. That cohort produces $319,200 a year.

Now a benefit passes and pays at 45% of your charges, which is squarely inside the range ADA's data reports for Medicaid fee-for-service. Your average annual net per senior patient falls to $342.

Across the same 420 patients, that's $143,640 a year, a drop of $175,560.

Look at it through Collections per Provider Hour and it gets sharper. A senior recall hour that collects $240 at your full fee collects $108 at 45%.

Your loaded hygiene cost for that hour is $68, so contribution per hour falls from $172 to $40.

If 12 hygiene hours a week across 46 working weeks serve that senior panel, the hygiene department alone gives up $72,864 a year.

The write-off percentage on those cases would read 55%, which tells you nothing about whether the hour is worth staffing. The $40 does.

What Most Owners Get Wrong: Reading a Benefit as New Demand

The mistake is made almost exclusively by practices with a heavy senior mix in stable, older suburbs, and it goes like this: "Half of Medicare beneficiaries don't see a dentist. A benefit brings them in. More patients, more production."

The underlying fact is true. KFF reports nearly half of Medicare beneficiaries didn't see a dentist in 2018, rising to 68% of Black seniors, 61% of Hispanic seniors and 73% of low-income seniors. There is genuine unmet need.

But here's what that argument misses. Your existing senior patients get converted first, on day one, automatically. The new patients arrive slowly, and they arrive disproportionately in the communities that have been underserved, which may or may not be your zip code. To replace $175,560 of lost collections at $342 a head, you need 513 additional senior patients.

That's more than doubling your senior panel, in the same building, with the same operatories, at the lower rate. Meanwhile the practices already treating the underserved population, the 41% who take public coverage, are the ones positioned to capture that demand.

Our call: if your senior patients currently pay full fee, a universal Medicare dental benefit is a repricing event disguised as a growth event, and you should model it as a loss before you model it as an opportunity.

The 57% That Decides Whether You Participate

You will get a participation choice, the same way you get one with every PPO. Run the Break-Even Retention Test on it before the sales pitch arrives.

Suppose instead of participating you build a senior membership plan: $348 a year covering two cleanings, exams and images, plus 15% off treatment. A typical senior in that plan adds about $255 of restorative at the discounted fee, for $603 a year in net collections.

Break-even retention equals net per patient under the plan divided by net per patient out of network: $342 divided by $603, or 57%.

You need to keep 238 of those 420 patients for staying out to beat participating.

Keep 238 at $603 and you collect $143,514, which is within a rounding error of the $143,640 you'd collect by participating with all of them.

So the question isn't ideological. It's whether you can hold 57% of a senior panel through a change that hands them a federal card they've waited decades for. In a practice with 20-year relationships and no comparable office within ten minutes, we'd take that bet. In a saturated metro with six offices in the same strip, we wouldn't. Know which one you are before the enrollment letter comes.

The Fight Isn't Only Between Parties

The reason this keeps stalling isn't just partisan. Organized dentistry is fighting itself. KFF lays out the split: a universal benefit at $238 billion over ten years, versus the ADA's rival means-tested design capping eligibility around $38,640 in individual annual income, which would cover roughly half of beneficiaries.

The means-tested version is cheaper, so it can theoretically pay closer to market rates for the people it covers. The universal version covers everyone, so it has to pay less. There's no third door where everyone is covered and you get paid well. Pick your poison: a broad benefit that reprices your whole senior panel downward, or a narrow one that pays acceptably but only for patients who mostly aren't in your chair today. Either way, the version that passes will not raise what you collect per hour from the seniors you already treat.

Three Things to Do Before the Fee Schedule Exists

Pull your senior cohort this week: count active patients over 65, their annual net collections, and what share of your hygiene hours they occupy. Compute Collections per Provider Hour for that cohort separately from everyone else, because it's the number that will move. Then build the senior membership plan now, while it reads as a gift instead of a defensive maneuver, and get patients enrolled before anyone in Washington gives them an alternative. Set up the KX modifier workflow for transplant, cardiac valve, head and neck cancer and dialysis clearances while you're in there.

We're tracking three things: whether S. 5089 moves out of Senate Finance at all, whether any drafted fee schedule is pegged to a percentile of regional commercial rates or built from scratch on a budget target, and how Medicare Advantage carriers reprice their dental riders in anticipation. A rate floor tied to commercial percentiles would change our position entirely. We've never seen one survive a CBO score.

If you want to know what leaving or staying would actually cost your practice, our PPO-exit calculator runs the Break-Even Retention Test on your own payer mix in about five minutes. Run your own numbers on the cohort you'd be repricing, not the one in our example.
