PCAB accreditation: what it actually attests

What is PCAB, and who operates it?

A private accreditation programme for compounding pharmacies, operated by ACHC — the Accreditation Commission for Health Care.

The distinction between private and governmental is the whole frame for this page. A state board of pharmacy licenses by law and can stop a pharmacy from operating. An accreditor assesses against its own published standards under a contract, and can withdraw a certificate. Both are real; they answer different questions, and only one of them is a condition of lawful operation.

ACHC describes its own programme as "the internationally-recognized benchmark for excellence in compounding practice." That is the accreditor's promotional characterisation of itself, quoted here as such. What matters for diligence is not the adjective but the mechanism underneath it, which is unusually checkable — each accreditation names the chapter it references.

What does an accreditation actually reference?

A named USP chapter, and a different one per scope.

ACHC also publishes when its standards were last aligned: revised PCAB non-sterile standards including USP updates to <795> took effect 1 June 2024, and revised sterile standards including USP updates to <797> took effect the same day.

This is the useful part. Accreditation is one of the few routes by which a USP chapter becomes binding on a particular pharmacy at all — the other being adoption by a state board, in a named and dated version. So an accreditation is not a vague quality signal; it is a contractual commitment to a specific chapter, and you can ask which.

Is "PCAB accredited" a complete statement?

No. Without a scope it names nothing.

There are three separate accreditations, granted per scope and never globally. A pharmacy can hold the non-sterile accreditation and not the sterile one, and if you are buying an injectable preparation the accreditation it holds may be precisely the one that does not cover your product.

So the question is which, not whether — and then ask to see the certificate's own dates. A badge on a website carries neither the scope nor the currency, and both are the parts that decide whether the accreditation is answering your question. What each chapter governs is set out at USP <795>, USP <797> and USP <800> — the third of which protects personnel and the environment from hazardous-drug exposure rather than describing preparation quality, and is routinely misread as a quality claim.

Does accreditation replace a state licence?

No — and the accreditor says so itself, which makes this the easiest misconception on the page to retire.

ACHC's own words: "If you are shipping compounded medications across state lines, the receiving state's BOP may require a specific license that is dependent on a nonresident inspection. This is not the same as accreditation."

That is the accreditor telling you its certificate does not answer the question most buyers use it to answer. Accreditation is checked as well as the state credential, never instead of it — and in several states the credential an out-of-state facility needs is not even issued by the board of pharmacy. How to run that check is at how to verify a compounding pharmacy’s state licence, and the credential itself is defined at non-resident pharmacy licence.

Is accreditation the same as an approval from FDA, or a certification from USP?

Neither, and the second one does not exist at all.

FDA's position is flat: "Compounded drugs are not FDA-approved." Accreditation is an assessment against a private standard; it is not premarket review of safety, effectiveness or quality, and no accreditation converts a compounded preparation into an approved drug.

A compounding pharmacy is not "USP-certified," "USP-approved" or "USP Verified" — those are factual errors rather than loose phrasing. USP writes the chapters and does not certify compounders. Across USP's own chapter and legal-recognition pages, it publishes no statement naming an enforcement body for the compounding chapters at all. USP Verification Services is a real programme, and it covers dietary supplements, dietary ingredients, active pharmaceutical ingredients and excipients — manufacturers, not compounders. A compounding page carrying that badge has described something that did not happen.

One smaller attribution worth keeping straight: <800> "became enforceable" on 1 November 2023 is ACHC's characterisation, while USP's own word for that date is "compendially applicable." They are not the same claim, and the stronger word belongs to the accreditor, not to USP.

What can you verify yourself, and what must you ask?

Very little of this is a public record, which is the honest answer and the reason the question list matters.

Federal registration under section 503B is public, and so is FDA's published compounding enforcement record. A state licence is verifiable with the issuing agency. Accreditation sits differently: it is a private contractual relationship, so the practical route is to ask the pharmacy for the programme, the scope and the certificate — and, if you want independent confirmation, to take that to the accreditor and not to the supplier's website.

Three questions with checkable answers:

• Which accreditations do you hold, and what scope does each cover?
• What are the dates on the certificate itself?
• Which USP chapter governs this preparation, which version are you working to, and which state's adoption makes that version binding on you?

The third question is not academic: the chapter version a pharmacy works to decides the beyond-use dating it may assign, and that date is defined at beyond-use date.

What could we not establish?

Three things, and they are the sort of detail a confident page would invent.

We did not find a published accreditation cycle length on the accreditor pages we read, so no number appears here. We did not find a statement that every accreditation involves an on-site survey — the accreditor publishes a final survey report delivered within ten business days of the last day of survey, which implies surveys happen, but implication is not a finding. And we did not research fees or renewal structure at all.

If a supplier or a competitor quotes you a cycle length, that number is not coming from anything we could verify on the accreditor's public pages. Ask for the certificate and read its dates, which is the version of that fact you can actually check.

Where does this sit in the rest of the check?

Accreditation is the fifth of the checks in how to vet a compounding pharmacy, and it is the one most often presented as covering the other four.

The public-record half of diligence is at how to read FDA’s registered-outsourcing-facilities list and what FDA’s compounding warning letters actually say. The documents that describe a specific batch rather than the business are at what per-batch documentation to ask for. Which federal pathway a supplier operates under, and why it changes what they may lawfully send you, is at 503A vs 503B.

To have a supplier's accreditations, credentials and pathway checked once and not re-checked per order, you can apply for an account.
