The gap between what hospitals and physician offices were paid by fee-for-service Medicare for outpatient cardiovascular tests increased between 2005 and 2015, as did the proportion of these tests that took place in hospitals, according to a new study in JAMA Internal Medicine.

Between the lines: When payment rates depended on where the tests were performed, there was a shift in volume toward the more expensive location.

  • The same didn't happen within a comparison group of 3 health maintenance organizations, for which reimbursement wasn't tied to the testing location.

By the numbers: Traditional Medicare paid hospitals 1.05 times more than doctors' offices for testing in 2005. This increased to 2.32 times more in 2015.

  • Meanwhile, the proportion of hospital-based testing increased from 21.1% in 2008 to 43.2% in 2015. In the control group, the proportion decreased from 16.6% to 15.2%.
  • This shift to the hospital setting cost an estimated $661 million in 2015.

Why it matters: Hospitals have fought fiercely against measures to create site-neutral payments, which the Trump administration proposed last year. The rule was recently overturned in court.

  • Advocates of site-neutral payments say they save taxpayers and seniors money.
  • "Site-neutral payments may offer an incentive for testing to be performed in the more efficient location," the authors of the study write.

The TikTok deal's for-show provisions and flimsy foundations

The new deal to rescue TikTok from a threatened U.S. ban — full of provisions aimed at creating the temporary appearance of a presidential win — looks like a sort of Potemkin village agreement.

How it works: Potemkin villages were fake-storefront towns stood up to impress a visiting czar and dignitaries. When the visitors left, the stage set got struck.

  • Similarly, many elements of this plan look hastily erected and easily abandoned once the spotlight moves on.

An estimated 2.5 million+ Americans have registered to vote on Facebook, Instagram, and Messenger, Facebook announced Monday. More than 733,000 Americans have registered to vote so far via Snapchat.

Why it matters: The broad reach of social media platforms makes them uniquely effective at engaging voters — especially younger voters who may not know how to register to vote or be civically engaged.
