A pharmacy may be able to tell you the current price using your plan and the price available through a discount option. Which costs less depends on the prescription, pharmacy, and your plan's terms. Ask the pharmacist to explain the available options before you fill.
This guide offers questions to help you compare the options without assuming one is best for every prescription. Use RxDiff to look up current local prices, then confirm the price and terms with the pharmacy and your plan.
Ask the pharmacy how each available payment option would be processed. A discount offer and an insurance claim may have different terms. Before choosing, ask whether the price is a cash price, how it relates to your plan, and whether the purchase would count toward any plan amount you are tracking.
Examples of discount services include RxDiff, GoodRx, SingleCare, and WellRx. Check the current offer terms and pharmacy participation for the exact prescription with the service and pharmacy.
If you want to use a discount offer, ask the pharmacy how to present it and whether it applies to your prescription. Do not assume an advertised discount or a prior quote applies to a different pharmacy or fill.
There is no universal answer. Compare the current price for your exact prescription with the amount and terms your plan provides. Ask your plan whether using a discount option affects any deductible or out-of-pocket amount you are tracking.
For metformin, lisinopril, or another medication, request a current quote for the exact prescription. Compare it with your plan's terms and ask whether either option affects deductible or out-of-pocket tracking.
Prices and plan terms can differ by prescription and pharmacy. Recheck the available options when you fill, and ask the pharmacist or plan to explain any difference.
Ask your plan before relying on a discount-card purchase to count toward a deductible or out-of-pocket amount. The answer depends on your plan's documents and rules. Ask the pharmacist how the transaction would be processed, and check your plan documents or contact your plan if tracking matters to you.
If you are tracking costs toward a plan amount, ask the plan how the available payment options are treated before filling. Compare the current pharmacy quote as well as the plan's explanation; do not assume one option will be less expensive overall.
If your plan documents do not answer a question about a discount offer or pharmacy transaction, contact your plan and ask the pharmacist to explain the options for the exact prescription.
Ask the pharmacist whether the discount offer can be used with your plan for the specific prescription and how each option would be processed. Check the offer terms and your plan documents; do not assume the options can be combined.
Before each fill, ask for a current quote and confirm with your plan which option applies to your benefits. A previous quote or explanation may not settle what applies to a later fill.
