Worse yet, non-fiduciary PBMs leverage the purchasing power of unsophisticated plan sponsors by negotiating with drugmakers and pharmacies for their financial benefit. Before non-fiduciary PBMs learned they could leverage the purchasing power of unsophisticated purchasers for their own financial gain, they focused on cost-efficiency or getting the best outcomes for the lowest cost. In many cases, the focus has shifted to promoting the products that are most profitable to the PBM.
Smart purchasers of PBM services want more control over their plan design not less. If this is you, here are six pillars upon which to design your pharmacy benefit plan.
If you're reading this and work for a self-funded employer never retain the services of a PBM or a PBM consultant who benefits when your pharmacy costs increase. Should you do so, never leave them completely to their own accord.
- Do you have the expertise within your company to design the pharmacy benefit plan? Or do you need pharmacy benefits education or the services of a pharmacy benefits consultant?
- How do you want to be involved in the management of the plan design after it is set up?
- Do you have the expertise and resources to manage the plan design or do you need to build in the incentives for the PBM to manage your program?
A formulary is a list of medications for which a plan will provide reimbursement. When considering a formulary, access defines the basic aspects of a pharmacy benefit design which includes but is not limited to:
- The products that will be covered
- The products that will not be covered
- The products that need prior approval
- Plan cap or maximum dollar amount a plan will pay for outpatient drug benefits
- Mail service benefits including specialty pharmacy, if any
- Pharmacy network makeup
III. Medication Adherence
Medication adherence is a large and growing issue that has an impact not only on patients’ health, but also on employer finances. Non-adherence to medications has been linked to 30-50% of treatment failures and 125,000 deaths each year, according to statistics gathered by the American College of Preventive Medicine.

Major cost-containment elements of pharmacy benefit plan design are plan restrictions, limitations and exclusions. There are many types of limitations used in varying degrees but they often lack the oversight [human] necessary to be effective over the long-haul. These elements encourage members to utilize low(er) cost alternatives:
- Therapeutic Substitution
- Mandatory Generic
- Plans caps or the maximum amount a plan will pay for outpatient drug benefits
- Partial fill programs or quantity limits on medication members can receive
- Step Therapy
Refers to the members out of pocket cost. There are three major types of cost-sharing: copayments, deductibles and coinsurance.
- When members receive a more costly alternative to a preferred product they are required to pay the higher copayment
- When members receive a branded product which has an available generic equivalent, they are required to pay the additional costs associated with the branded

According to the economic principles of demand, as price increases, demand tends to decrease. In the case of prescription drugs, price is the member's OOP (out-of-pocket). As cost sharing increases, utilization decreases. However, it's a catch twenty-two as there is a point of diminishing returns. You don't want utilization to decrease so much that it causes an increase in hospitalizations or emergency room visits, for example.
