Senate Republicans blocked the $35 cap on out-of-pocket spending on insulin for patients enrolled in private insurance in the reconciliation package.

Why it matters: The drug costs eight times more in the U.S. than 32 other high-income nations, according to a 2020 study commissioned by the Health and Human Services Department.

What we're watching: The change to the climate, tax and health care package came during the amendment process that allows any senator to force a vote on proposed tweaks to the measure.

Between the lines: Even though the $35 cap for the private insurers has been stripped from the package, Democrats are hoping to preserve the $35 insulin cap for patients on Medicare.

The big picture: Capping out-of-pocket insulin costs — a narrow sliver of President Biden's stalled Build Back Better package — has been a priority for Democrats, particularly ahead of this year's midterms.
