What happened?

A federal drug discount program that hit $100 billion in purchases in 2025 has become the center of a Capitol Hill fight, with two competing bills now in play and a clock ticking toward a January 2027 launch date for a new rebate system. [](#ngr-76bbf56b-728b-45c5-856d-50d3df71b807)

The program in question is the 340B drug discount program, a decades-old federal system that requires pharmaceutical companies to sell drugs at steep discounts to hospitals, clinics, and health centers that serve low-income patients. The dispute is over whether those discounts should be replaced with a rebate model, and who gets to decide.

Why Does it Matter to Me?

More than 31.5 million patients receive care at community health centers and federally qualified health centers that rely on 340B savings to keep their doors open and services affordable. Nearly 60 percent of all U.S. pharmacy locations operate as contract pharmacies under the program, meaning the rules here touch a wide slice of where Americans actually pick up their prescriptions.

If the rebate model moves forward on its current timeline, the way those discounts flow to health centers would change. Supporters of the rebate approach say it would reduce fraud and duplicate billing. Critics say it would delay or reduce the money that safety-net providers depend on.

Both sides, now

A bipartisan group of senators introduced the SUSTAIN 340B Act to eliminate the rebate pilot outright. On the House side, Reps. John Joyce (R-PA-13) and Scott Peters (D-CA-50) introduced the SECURE 340B Act on July 6, which would freeze rebates for four years and create an independent clearinghouse to verify claims and prevent duplicate discounts.

The pharmaceutical industry is not waiting for Congress to act. The trade group PhRMA is running seven-figure advertising campaigns in support of the rebate model. On the other side, health centers and covered entities argue that since 2020, 41 drug manufacturers have already restricted access to 340B discounts through contract pharmacy limits, squeezing safety-net providers before any new system is even in place.

One would kill the rebate pilot. The other would pause it while a new verification system is built. Congress has not reconciled the two approaches.

What happens next?

Manufacturer plans for the rebate pilot are expected to receive approvals Sept. 24, with a launch set for Jan. 1, 2027. Neither the SUSTAIN 340B Act nor the SECURE 340B Act has advanced to a floor vote in either chamber. For either bill to change that timeline, it would need to clear committee, pass a full chamber vote, and be signed into law before the January launch date. No hearing or vote is currently scheduled on either measure.
