How Federal Employees Can Save Hundreds on Prescription Drugs Each Year

These are some ways federal employees can save on prescription medications with their FEHB insurance.

Federal employees often assume their FEHB prescription coverage automatically delivers the lowest possible price. In reality, the system has several layers—formularies, pharmacy networks, and pricing rules—that mean the same drug can cost very different amounts depending on how it is purchased.

Understanding a few strategies can significantly reduce prescription costs for federal workers and retirees.

1. Use Your Plan’s Preferred Pharmacy Network

Most FEHB plans negotiate lower prices with certain pharmacies. Using those preferred pharmacies usually produces the lowest copay.

For example, many FEHB plans route prescriptions through pharmacy benefit managers such as:

  • CVS Caremark
  • Express Scripts
  • OptumRx

These organizations negotiate pricing with retail pharmacies and set the copay tiers for your plan.

A simple rule many federal employees overlook: Check whether your plan has a “preferred pharmacy” list before filling a prescription.

The difference can be substantial. A drug that costs $20 at a preferred pharmacy may cost $50–$80 at a non-preferred location.

2. Switch to Mail-Order for Maintenance Medications

Most FEHB plans offer 90-day mail-order prescriptions for drugs taken regularly, such as:

  • blood pressure medications
  • cholesterol drugs
  • diabetes medications

Mail order often reduces costs in two ways:

  • lower copays for 90-day supplies
  • fewer pharmacy dispensing fees

For example, a typical FEHB structure might be:

SupplyRetail CostMail Order
30-day supply$15
90-day supply$45$30

For retirees on fixed income, this is one of the easiest long-term savings strategies.

3. Consider the Generic Version

Generic drugs are chemically identical to brand-name medications but cost dramatically less.

Within FEHB plans, drugs usually fall into tiers:

TierDrug TypeTypical Cost
Tier 1GenericLowest copay
Tier 2Preferred brandModerate
Tier 3Non-preferred brandHigher
Tier 4Specialty drugsHighest

A generic medication can cost 80–90% less than the brand equivalent.

A simple question to ask your physician: “Is there a generic alternative on my FEHB formulary?”

4. Compare Prices Outside Your Insurance

Sometimes the cash price for a drug is actually lower than the insured copay. Price-comparison tools can help identify cheaper options, including:

  • GoodRx
  • Mark Cuban Cost Plus Drug Company

These platforms show discounted prices across pharmacies and can occasionally beat insurance pricing for generic drugs.

Federal employees often overlook this option because they assume insurance must always be cheaper.

5. Review Your FEHB Formulary Each Year

Every FEHB plan publishes a formulary list showing which drugs are covered and at what cost tier. This list can change annually.

During FEHB Open Season, a drug that was Tier 2 under one plan might be Tier 3 under another plan, potentially doubling the cost.

Federal employees who take ongoing medications should review:

  • the formulary
  • copay tiers
  • specialty drug policies

before selecting a plan for the next year.

6. Use Preventive Drug Programs

Many FEHB plans provide $0 copay medications for certain preventive treatments. Examples often include:

  • statins for cholesterol
  • insulin or diabetes medications
  • blood pressure drugs

These programs exist because preventive treatment lowers long-term health costs.

7. Coordinate With Medicare (for Retirees)

Once federal retirees enroll in Medicare, prescription costs may be affected by:

  • Medicare Part D
  • FEHB drug coverage
  • coordination rules

Some retirees keep FEHB drug coverage alone, while others add Part D for additional savings depending on their medication needs.

The best choice depends heavily on drug type, cost, and usage frequency.

A Quick Federal Employee Example

Consider a federal retiree taking three maintenance medications:

DrugRetail CostStrategy UsedAnnual Cost
Blood pressure$15/monthMail order$120
Cholesterol$25/monthGeneric substitution$200
Diabetes drug$90/monthPreferred pharmacy$720

Without these strategies, the annual cost could exceed $1,800–$2,000. With them, the retiree reduces costs to about $1,040 per year.

So, What Should You Do?

Federal employees already have strong prescription coverage through FEHB, but the lowest price rarely happens automatically.

The best results usually come from:

  • using preferred pharmacies
  • switching to mail-order for maintenance drugs
  • choosing generics whenever possible
  • comparing prices outside insurance
  • reviewing formularies during Open Season

Small adjustments in how prescriptions are filled can produce hundreds—or sometimes thousands—of dollars in annual savings.
