One of the most important — and least understood — decisions a new independent pharmacy owner makes is how to get contracted with insurance companies and PBMs. Should you join a PSAO and let them negotiate on your behalf, or go direct with each payer yourself? The answer affects your reimbursement rates, the breadth of insurance plans you can accept, and how much administrative work you're taking on. Here's what you actually need to know.
What Is a PSAO?
A PSAO — Pharmacy Services Administrative Organization — is an organization that aggregates independent pharmacies together to negotiate contracts with PBMs (Pharmacy Benefit Managers) and insurance networks. Think of it as a group purchasing organization, but specifically for pharmacy reimbursement contracts.
When you join a PSAO, your pharmacy becomes part of their network. The PSAO negotiates contract terms, reimbursement rates, and administrative requirements with each PBM on behalf of all their member pharmacies. You get access to those contracts under their umbrella without having to individually negotiate with each payer.
Major PSAOs that serve independent pharmacies include PAAS National, PRS Pharmacy Services, EzriRx, and several others. Your wholesaler relationship often comes with a preferred PSAO recommendation as well.
What Does "Going Direct" Mean?
Going direct means applying individually with each PBM and insurance network — Express Scripts, CVS Caremark, OptumRx, Prime Therapeutics, and dozens of regional and employer plans — to become a participating pharmacy. Each application requires its own documentation, credentialing requirements, and processing timeline. Once approved, you negotiate (or more accurately, accept) the terms each PBM offers.
The Case for Joining a PSAO
For the vast majority of new independent pharmacies, joining a PSAO is the right choice. Here's why:
Speed to Coverage
A PSAO can get you contracted with the major PBMs under a single application. Instead of filing 20+ individual applications and waiting 3–6 weeks each, one PSAO enrollment can have you in-network with most major payers within 30–60 days. For a pharmacy trying to open and start generating revenue, this is enormously valuable.
Negotiated Rates
Individual independent pharmacies have almost no negotiating leverage with large PBMs. Express Scripts, for example, pays a rate — you either accept it or you're not in network. A PSAO, negotiating on behalf of thousands of pharmacies, has meaningful leverage to negotiate better rates or terms than any single independent could achieve on their own.
Administrative Simplification
Instead of managing your credentialing status, contract updates, and compliance requirements with 20+ different payers separately, a PSAO handles that centrally. When your address changes, your PIC changes, or your licenses renew, you notify the PSAO and they update all networks. This alone saves dozens of hours per year.
Audit Support
PBM audits are a fact of life for independent pharmacies. PSAOs typically provide audit support services — reviewing your dispensing records, identifying potential issues before an auditor does, and helping you respond to audit findings. Going direct means facing audits without that institutional support.
The Case for Going Direct (and When It Makes Sense)
Going direct isn't always wrong — there are specific scenarios where it makes sense.
Specialty Pharmacy Networks
Specialty pharmacy networks (for oncology drugs, rare disease medications, REMS products) often require direct contracting with specific specialty distributors and PBMs. These networks are separate from what a general retail PSAO covers. If you're opening a specialty pharmacy, direct contracting with specialty networks is part of the picture regardless of your retail PSAO status.
Local or Regional Plans
Some regional insurance plans and employer-sponsored plans don't contract through PSAOs. Depending on your geographic market, there may be a meaningful percentage of patients covered by plans where you'll need to go direct regardless. This isn't a reason to skip the PSAO — it's a reason to understand that PSAO + some direct contracts is often the right full picture.
Established Pharmacies with Negotiating History
A pharmacy that has been operating for 5+ years, has documented dispensing volume, strong quality metrics, and established relationships may have grounds to negotiate direct contracts at rates competitive with PSAO rates. For brand-new pharmacies, this leverage does not yet exist.
The PSAO Fee Structure: What You're Paying For
PSAOs typically earn revenue through a spread — the difference between what PBMs pay the PSAO and what the PSAO passes through to member pharmacies — rather than a direct membership fee. Some PSAOs also charge administrative or enrollment fees. It is important to understand the full economics of any PSAO agreement before signing, specifically:
- What percentage of claims revenue are they retaining?
- What is the contract term and exit process?
- What networks are included versus excluded?
- What audit and compliance support services are included?
- How do DIR (Direct and Indirect Remuneration) fees work within their model?
DIR Fees: The Hidden Cost All Pharmacy Owners Must Understand
DIR fees — Direct and Indirect Remuneration — are retroactive fees that PBMs collect from pharmacies after the point of sale, often 3–6 months later, based on "performance metrics" that are largely opaque. DIR fees have been one of the most financially damaging developments in independent pharmacy economics over the past decade, and understanding how your PSAO manages DIR fee exposure is critical to evaluating any PSAO agreement.
CMS made rule changes effective January 2024 that require DIR fees to be reflected at the point of sale rather than collected retroactively for Medicare Part D plans. This is a significant change that improves predictability for pharmacy cash flow, but understanding the transition and how it affects your PSAO's model is important.
Our Recommendation
For every independent pharmacy we open, we enroll with a PSAO before opening day. It is the fastest path to broad network coverage and removes a massive administrative burden from your plate at the exact moment when you have the least capacity to handle it. We evaluate PSAO options based on your geographic market, your anticipated payer mix, and the specific terms each PSAO offers.
The PSAO decision — like most decisions in the pharmacy opening process — benefits enormously from having someone in your corner who has sat across these negotiating tables before and knows what good terms look like versus what you should push back on.
We negotiate PSAO enrollment and wholesaler terms on your behalf.
From PSAO selection to PBM contracting to wholesaler negotiations, we handle the complete vendor and payer setup as part of our turnkey service.
