Medicare days in hospital payments

In brief

Summary: written with AI from the case record.

What it's about
The dispute centered on whether patients who qualify for Medicare Part A count in the Medicare part of that formula even if Medicare did not actually pay for their hospital stay, and the Court held that they do.
A technical definition in Medicare law can affect payments to hospitals serving low-income patients.
Question presented
Whether the Secretary has permissibly included in a hospital's Medicare fraction all of the hospital's patient days of individuals who satisfy the requirements to be entitled to Medicare Part A benefits, regardless of whether Medicare paid the hospital for those particular days.
What the Court decided
Holding
In calculating the Medicare fraction, individuals “entitled to [Medicare Part A] benefits” are all those qualifying for the program, regardless of whether they receive Medicare payments for part or all of a hospital stay. 958 F. 3d 873, reversed and remanded.

- Reversed
The vote
From the opinions
“In my view, the answer to that narrow question is straightforward and commonsensical: No.”
What's next
The Ninth Circuit will now apply the Supreme Court's counting rule to the hospital's reimbursement calculation after the case was sent back (remanded). The ruling does not itself set the hospital's final payment.
