Implementation Is Part of the Sale: What TPAs Should Test Before Recommending a PBM

A PBM can win the finalist meeting and still create a bad client experience at go-live.

For a TPA, that matters.

The employer may have selected the PBM, but the TPA often helped bring that partner into the conversation. If the transition goes poorly, the employer is unlikely to separate the PBM problem neatly from the TPA relationship.

If the transition does not work, flexibility on paper will matter very little to the employer or its members.

As pharmacy benefit models give employers more choices, implementation can also involve more moving pieces. PSG notes that a standard procurement typically takes up to 20 weeks, while a modular pharmacy benefit procurement may take twice as long. It recommends beginning approximately 15 months before the intended implementation date.¹

That is one model, but the operating lesson is broader:

More moving pieces require clearer ownership and more planning.

That is why implementation should be tested before the sale.

Here are five areas I would pressure-test.

1. Start with ownership, not the timeline

A go-live date is useful.

A clear list of who owns what is more useful.

Who owns eligibility?

Who validates accumulator data?

Who manages pharmacy benefit setup?

Who handles member communications?

Who makes the decision if a test file fails?

Who takes the issue when it crosses between the TPA, PBM and another partner?

Implementation gets harder when accountability is vague.

A good plan should make ownership clear before the work begins.

2. Test the data path before members depend on it

Eligibility and claims data are not back-office details. They determine whether the benefit works.

The same is true for accumulators, reporting feeds and information that has to move between organizations.

A TPA should understand what data is required, who sends it, how it is tested and what happens when something does not reconcile.

The question is not simply:

Can the systems connect?

It is:

How will we know the information is right before members rely on it?

3. Plan for the member who does not follow the standard path

Most implementations look clean in a project plan.

Members are where the exceptions appear.

Someone may be in the middle of a prior authorization. Another person may be taking a high-cost medication. A pharmacy may no longer be in network. A formulary change may require a different medication or a new approval.

Transition planning should include more than files and dates.

Ask how exceptions will be identified, who will contact the member when support is needed and how unresolved issues will be escalated.

Prescription care does not stop because the implementation calendar says the new plan started.

4. Test the handoffs

More pharmacy benefit choice can create more places for information or responsibility to get lost.

If a client uses another specialty, clinical or access partner, who makes sure eligibility, claims, accumulators, member communications and reporting still work?

And when an issue crosses those boundaries, who owns the next step?

Different systems can do different jobs.

The TPA should not have to become the organization stitching them together.

5. Ask for proof of execution

Every PBM can describe an implementation process.

The better question is what the organization can show.

Ask how the PBM distinguishes an expected claim reject from an avoidable configuration error.

Ask how unexpected rejects are tracked, whether they affected members and how quickly member-impacting issues were resolved.

Ask how implementation issues are tracked and who owns them through closure.

Ask what types of clients, benefit complexity and partner configurations the implementation team has handled.

And ask for examples that resemble the employer you are considering bringing to the PBM.

Process matters.

Proof matters more.

Implementation risk should be tested before the contract is signed

For a TPA, implementation is part of the sales decision because the TPA’s reputation stays attached to the recommendation.

The question is not only:

Can this PBM launch the client?

It is:

What has to be true on day one, how do we know it is ready and who owns the next step if something goes wrong?

That is the implementation conversation worth having before the employer says yes.
