Built for This Moment: Provider CSAO, HR 3164, and the Infrastructure That Was Always Ready

When Provider CSAO was founded in 2022, the question of whether pharmacists would ever be formally recognized by Medicare — and fairly compensated — as healthcare providers hung unanswered in Congress. We built this company on the conviction that the answer would be yes, and that the pharmacists didn’t have to wait. We knew that the pharmacist who was prepared when it happened would have a decisive advantage over those who waited.
That moment has arrived. On May 21, 2026, the House Ways and Means Committee advanced H.R. 3164: the Main Street Pharmacy Access Act (formerly ECAPS) to the full House floor. For the first time in history, pharmacists stand to be formally designated as healthcare providers under the Social Security Act, with Medicare Part B reimbursement to match. Provider CSAO is not watching from the sidelines. We have been executing this playbook: credentialing pharmacists, contracting with medical payers, and building the billing infrastructure since day one.
What Just Happened — and Why It’s Historic
The Ways and Means Committee controls Medicare policy. A bill that clears this committee on a bipartisan vote has overcome one of the highest hurdles in healthcare reform. With 112+ bipartisan co-sponsors and a Senate companion (S. 2426), the momentum is the strongest this legislation has ever seen. Major pharmacy organizations including APhA, NACDS, ASHP, and ASCP responded immediately, calling it a “long-standing advocacy priority” and noting that Medicare had “lagged behind” commercial payers and state Medicaid programs that have already moved to recognize pharmacist services.
The Medicare Modernization Act of 2003 critically left pharmacists off from the list of billable practitioners. That was a two-decade mistake. HR 3164 is the first step in correcting that omission.
Why Ways & Means Matters
The House Ways and Means Committee writes Medicare law. A bill that clears this committee on a bipartisan vote has already passed the most consequential test in healthcare legislation. When the committee acts, the full House listens and the Senate takes note.
Recognition AND Parity: Both Are Real
HR 3164 delivers two distinct victories. Recognition means being formally named in the law as a Medicare provider under the Social Security Act — a historic first that ends a decades-long statutory exclusion. But recognition without fair pay is just a title.
Parity is being paid comparably for the same service. At 85% of the physician fee schedule, pharmacists are reimbursed at precisely the same rate as nurse practitioners and PAs — a deliberate signal that pharmacist services carry equivalent clinical value. At 100% during public health emergencies, the bill grants full physician-rate parity at the exact moments pharmacies serve as the frontline of care. This is not a consolation prize. It is the economic validation the profession has been fighting for.
Provider CSAO’s Infrastructure Is Already In Place
Here is what separates Provider CSAO from every other voice commenting on this legislation: we have been building the exact infrastructure HR 3164 requires since 2022. While others have been watching Washington, our network has been hard at work implementing the framework this bill will now codify at the Medicare level.
Pharmacists in our network are already receiving direct reimbursement from Medicare Advantage payers as rendering providers — billing on the medical benefit, not just the pharmacy benefit. This is happening in our network today.
Our credentialing process brings pharmacists to active payer status in an average of 90 days from application.
We have documented revenue improvements of up to 600% when pharmacies transition from pharmacy-benefit to medical-benefit billing.
We are monitoring the Medicare B changes for our pharmacists’ Type 1 NPIs — the individual practitioner identifier required to bill Medicare directly as a licensed provider.
On Type 1 NPIs: A Type 1 NPI is the same individual identifier used by physicians, NPs, and PAs to bill Medicare. Enrolling pharmacists under Type 1 NPIs, credentialing them with payers, and activating Medicare Part B billing is exactly the infrastructure HR 3164 requires — and Provider CSAO is already utilizing it. When this law passes, our partners won’t need months to prepare. The switch is nearly already flipped.
A look forward
We believe HR 3164 is just the beginning. Nearly all states have some form of pharmacist provider status legislation, but many are incomplete, underfunded, or fail to require meaningful reimbursement from commercial payers. Federal Medicare recognition changes the calculus entirely.
When Congress writes pharmacists into the Social Security Act and Medicare begins cutting reimbursement checks for clinical services, it becomes politically and economically untenable for state Medicaid programs and commercial payers to fail to adapt. Why would any state Medicaid program refuse to cover what federal Medicare covers? We expect HR 3164 to directly accelerate pending provider-status victories in multiple states — and our scope-of-practice tracker is monitoring all 50.
Federal Medicare provider status is the rate limiting step for ending state-level resistance. It signals that pharmacists’ clinical value has been adjudicated at the highest level of American healthcare policy — and that states and payers who haven’t aligned will find themselves increasingly out of step with the national standard.
What to Do Now
HR 3164 still needs a full House vote and Senate passage. The time to prepare is before it’s signed, not after.
1 Verify your Type 1 NPI
Individual pharmacist NPI enrollment is the foundation of Medicare Part B billing as a practitioner. Confirm yours in NPPES today.
2 Get CLIA certified
In-pharmacy testing for flu, COVID, RSV, or strep requires CLIA certification. Allow 4–12 weeks — start now.
3 Review your state scope-of-practice laws
HR 3164 does not override state law. Know which services you’re authorized to provide and get any required collaborative practice agreements in place. Check your state SOP Here: www.providercsao.com/sop
4 Get credentialed and contracted today
Provider CSAO can credential your pharmacists with Medicare Advantage and commercial payers in ~90 days. Start the clock now — not after the bill is signed.
Provider CSAO was built for this moment. Since 2022, we have been doing the credentialing, contracting, and administrative work that most pharmacists cannot do efficiently on their own. The pharmacists in our network are already billing on the medical benefit.
The Main Street Pharmacy Access Act is validation that the work was always pointing in the right direction.
The moment is here. We have been ready. Let’s make sure you are too.
