The Annual Prescription Cost Checkup: A 20-Minute Routine

An annual prescription cost checkup is a short yearly routine, roughly 20 minutes per medication, where you review your current drugs against your plan's updated formulary, compare pharmacy prices, and check for newly available generics or discount programs. Insurance formularies and drug prices change every year, so a routine that took no time to set up can quietly become expensive if you never revisit it.

Most people set up their prescriptions once and don't think about them again until something changes unexpectedly, like a higher-than-usual copay at the counter. A short annual review can catch these changes before they surprise you, especially around open enrollment when plan details reset.

Step 1: Pull your current medication list

Start with a simple list of every prescription you currently take regularly, including dose, quantity, and how often you refill. If you use one pharmacy consistently, they can often print or email a full medication history, which is useful both for this review and for general safety, since MedlinePlus recommends keeping your pharmacy informed of everything you take so they can check for interactions.

Step 2: Check your plan's current formulary

Your insurance plan's formulary, the list of covered drugs and their cost tiers, can change every plan year. A drug that was a low-cost "preferred generic" tier last year might move to a higher tier, or your insurer might add new coverage requirements like prior authorization. HealthCare.gov's guidance on Marketplace prescription coverage recommends checking your plan's current formulary directly through your insurer's website, your Summary of Benefits and Coverage, or by calling your insurer, since coverage details aren't always obvious from your insurance card alone. Do this for each medication on your list, not just the ones you assume might have changed.

Step 3: Compare pharmacy prices for each drug

Even if your formulary hasn't changed, pharmacy cash prices and negotiated rates shift throughout the year. Compare prescription prices on BetterBuyRx for each medication on your list, checking a few pharmacies near you rather than assuming your current pharmacy is still the cheapest option. This is especially worth doing for any drug you pay cash for, whether because you're uninsured, your deductible hasn't been met, or the drug isn't covered by your plan.

Step 4: Check for new generic or lower-cost alternatives

Generic versions of brand-name drugs become available on an ongoing basis as patents expire. If you've been on the same brand-name medication for a few years, it's worth checking whether a generic has since launched. According to the FDA, a single new generic competitor typically lowers prices by around 30%, and five or more competitors are associated with drops of nearly 85%. Search generic medication savings as part of your annual review, and bring anything you find to your next appointment as a question for your doctor, since only they can determine whether switching is clinically appropriate for you.

Step 5: Revisit any discount cards or coupons you use

If you use a manufacturer copay coupon or a prescription discount card, check whether it's still your best option. Manufacturer coupons often have annual caps, and some insurance plans use copay accumulator or maximizer programs that change how coupon value counts toward your deductible, according to KFF's analysis of copay adjustment programs. If your plan's rules changed since last year, a coupon that used to help you might now leave you with an unexpected bill once it runs out.

Step 6: Check your deductible and out-of-pocket progress

If your plan resets deductibles and out-of-pocket maximums annually, which most do at calendar-year or plan-year start, check where you stand early in the year rather than discovering the reset mid-prescription. This affects decisions like whether to use insurance versus a cash discount price for a given fill, since paying through insurance (even at a higher immediate cost) counts toward your deductible, while a cash discount card purchase typically does not.

Why timing matters

Doing this review around your plan's renewal date, often January 1 for calendar-year plans, or during open enrollment for Marketplace and employer plans, means you catch formulary and pricing changes before they hit you mid-year. If you take multiple medications, spacing this out (a few drugs each week) can make it more manageable than trying to review everything in one sitting.

Check prices near you as the first concrete step in this routine, since it's the fastest way to see whether anything has shifted since your last fill.

Bring findings to your doctor or pharmacist, not just your insurer

The annual checkup surfaces questions, not answers. If you find a generic alternative, a lower-cost pharmacy, or a formulary change, the next step is a conversation, not a unilateral switch. Ask your doctor whether an alternative is clinically appropriate, and ask your pharmacist whether a specific discount or program applies to your situation. What to ask your pharmacist about costs has more detail on framing these questions efficiently.

Keep expectations realistic

An annual review won't eliminate all cost surprises, since manufacturer price changes and formulary updates can happen outside your control and sometimes outside the typical renewal cycle. But a consistent yearly routine catches the predictable changes, plan renewals, new generics, coupon rule changes, before they become a shock at the pharmacy counter. Prices vary by pharmacy, location, quantity, and eligibility, so this is a recurring task, not a one-time fix.
