On July 2, CMS dropped the CY 2027 outpatient payment proposed rule. It's a fat, sleepy document that most people will skim and forget. Buried in it is one line that should make every health system CFO put down their coffee. CMS wants to keep expanding site-neutral payment, and this year it goes after imaging without contrast done in hospital-owned outpatient departments. Same scan, same machine, same reading. Medicare just wants to stop paying a hospital premium for it when the hospital bought a building down the street and called it an outpatient department.
Here's the part nobody at the hospital association will say out loud. This is Medicare admitting, in writing, that you have been charging more for the parking lot than the medicine. The rule says the quiet thing plainly. CMS wrote that the policy "helps ensure that beneficiaries are not subject to higher premiums and cost sharing based solely on the site at which care is furnished." Read that again. Solely on the site. Not the quality. Not the outcome. The address.
The numbers are small this year and that's the point. CMS estimates the imaging piece saves Medicare about $260 million in the first year, with roughly $70 million of that coming straight off what patients pay in premiums and another $70 million off their cost sharing. (Those are CMS's own estimates from the fact sheet, worth a look before anyone drops them in a board deck.) A quarter of a billion dollars is a rounding error in a $110 billion outpatient program. But the direction is the whole story. First it was clinic visits. Then drug administration. Now imaging. Every year the list of things you can no longer overcharge for just because you own the walls gets a little longer. The building markup is dying by a thousand cuts, and CMS is holding the knife.
And they're not stopping at price. The same rule keeps phasing out the inpatient-only list, moving 638 procedures out of the hospital and into cheaper outpatient settings, because, in CMS's words, medicine has evolved and the work can be done safely somewhere less expensive. (That count is from the CMS fact sheet. A law firm summary I read said 637, so pin the exact number before you quote it.) Put the two moves together and you see what the agency actually believes. The site of care has been inflated for years, and the fix is to keep pushing care to the lowest-cost place that can still do it well.
So let me ask the obvious question the rule doesn't. If the site shouldn't change the price of a scan, why does it change the price of everything else? Why is a blood pressure check, a medication review, a diabetic's day-40 follow-up call worth more when it happens inside a hospital's cost structure than when it happens in the patient's kitchen? It isn't. It's worth less there, honestly, because half the time it doesn't happen at all. The most expensive site of care in America is the one nobody books. The follow-up that never gets scheduled. The refill that lapses. The symptom that turns into an ED visit at 2 a.m. because there was no one between the office visits.
This is where I get annoyed at the conventional wisdom. For twenty years the industry has treated the hospital campus as the center of gravity and everything else as a satellite. Build the tower, fill the beds, bill the facility fee. I sat on the payer side and watched us pay those fees knowing full well the same care could be delivered for less somewhere else. We paid anyway because the contracts said so and nobody wanted the fight. CMS is finally picking the fight. The smart operators should get in front of it instead of lobbying to slow it down.
Because the logic doesn't stop at imaging, and it doesn't stop at the outpatient department. Extend it to its natural end and you land in the home. That's the lowest-cost site there is. No facility fee. No building. No parking structure to amortize. Just a nurse, a care plan, and a patient who actually picks up the phone on day 40 because someone built a system to call. When you manage a chronic patient at home between visits, you don't just save the site differential CMS is chasing. You prevent the readmission that would have cost forty times the scan. The savings CMS is fighting over in this rule are real but tiny next to the money sitting in avoided acute care.
What do you do Monday morning? Two things.
First, stop assuming the hospital outpatient department is where ambulatory care belongs. Pull your top service lines and ask which ones are sitting in a high-cost site purely out of habit and contract inertia. Imaging, infusions, minor procedures, routine follow-up. If Medicare is going to keep neutralizing the premium anyway, you want to move before the rate does, not after. The groups that relocate care ahead of the payment change keep the margin. The ones who wait get the cut handed to them.
Second, and this is the bigger one, look at your chronic-disease population and count how much of that care is stuck in the most expensive settings you run. The office visit and the readmission. Almost none of the real work of managing a hypertensive or a diabetic needs to happen in either place. It needs to happen at home, on a schedule, run by a team that reaches the patient between appointments. If your practice can staff and run that itself, do it. If it can't, and most can't right now, hand it to a partner who runs it end to end and gets paid out of what actually gets billed. Either way, get the care out of the building.
Medicare just told you the address is a scam. Believe them, and move your care to where it's cheapest and best before the rule makes you.
