On Oct. 10, 2018, two short federal laws took away a contract term many patients never knew existed. Before then, some agreements between pharmacies and drug plans barred pharmacists from telling a customer that paying cash would cost less than using insurance. The Patient Right to Know Drug Prices Act1 ended those gag clauses for private health plans, and the Know the Lowest Price Act2 did the same for Medicare drug plans.
Neither law requires a pharmacist to volunteer the cheaper option. They make it permissible to say so. In practice the conversation still tends to start with the patient asking.
This page is a script for that conversation, with specific, polite questions about price, quantity and paperwork, each with a note on why it helps. It is printable and works on the phone or at the counter. Anything about whether a medicine, strength or supply length is right for a particular person belongs with the prescriber or pharmacist, and the script marks those points.
What to have in front of you
A price quote is only comparable from one pharmacy to the next if it is for the same thing. Before calling or walking in, gather these details.
- The exact drug name as written on the prescription or the current label
- The strength (for example, 10 mg) and the dosage form (tablet, capsule, liquid, cream)
- The quantity and the number of days it covers
- Your insurance card, if you have one
- The name of your current pharmacy, if you might transfer
The prescription label carries most of this, and the NDC number on it pins down the exact product and package.
The questions, and why each one helps
| Question | Why it helps |
|---|---|
| "What will this cost me with my insurance today?" | Gets your actual copay or coinsurance, which can change with your deductible and the time of year |
| "What is your cash price for the same drug, strength and quantity?" | Federal law allows the pharmacist to tell you when paying without insurance costs less |
| "If I pay the cash price, will it count toward my deductible?" | A purchase outside your plan may not count toward your deductible or out-of-pocket limit; your plan has the final answer |
| "Is this the generic version?" | Confirms what you are being quoted; generics have the same active ingredient, strength, dosage form and route as the brand |
| "If this is a brand, is there an approved generic?" | If there is, you can raise it with your prescriber, who decides whether it suits you |
| "What would a 90-day supply cost, compared with three 30-day fills?" | Per-fill costs are spread over more tablets, and some plans price 90-day fills differently |
| "Does my plan require a specific pharmacy or mail order for 90-day fills?" | Some plans only cover longer supplies through certain pharmacies |
| "Is this pharmacy preferred or in network for my plan?" | Copays can be lower at preferred pharmacies |
| "Does my plan need prior authorization or have a quantity limit for this?" | Explains a surprise rejection or a higher price before you reach the counter |
| "Is there a different package size that costs less for the same total amount?" | Pharmacies sometimes price package sizes differently |
| "Has the manufacturer of this generic changed since my last fill?" | Explains a pill that looks different, and tells you which maker's product you have if a recall is announced |
| "Can you write the price on my receipt or a note?" | Gives you a record to compare against other pharmacies and future refills |
Questions that belong with your prescriber
Some savings need a new or changed prescription. A pharmacist can tell you the price difference; the prescriber decides whether a change fits the treatment. Three ways to put it that tend to work: "The pharmacist told me there's a generic for this. Would that be appropriate for me?" Or: "Cost is a concern for me with this prescription. Are there options you'd consider that cost less?" Or: "Would a 90-day prescription make sense for me, or should we wait?"
A prescriber may say no for good reasons. A medicine someone has just started, or one whose dose is still being adjusted, may be better filled in shorter amounts. That is their call, and GxRadar's piece on 90-day supplies goes through the trade-offs.
Why the questions work
The pharmacist can see both prices
When a prescription runs through insurance, the pharmacy system shows what the plan will pay and what the patient owes. The pharmacy also has its own price for customers paying cash. Asking for both side by side puts the comparison on the counter.
Both 2018 laws passed as Senate bills, S. 2554 and S. 2553, according to the legislative history printed with each public law1, and both prohibit plans from restricting a pharmacy from telling an enrollee about the lower price. The Medicare version applies to plan years beginning on or after Jan. 1, 2020, the statute says2. GxRadar's explainer on when the cash price beats the copay covers the research that prompted them.
Most generic fills already cost little
In Medicare, the typical generic copay is small. In 2022 the average Part D enrollee paid $2.92 out of pocket per 30-day equivalent of a generic, and 94.6 percent of fills for drugs with a generic alternative were filled with the generic, according to a 2024 issue brief from HHS's planning office (ASPE)3. The script matters most when a patient's cost is well above that.
Pharmacies' own costs for many generics are lower still. The CMS NADAC survey4 put the average acquisition cost of a lisinopril 10 mg tablet at about 1.8 cents in October 2026, by GxRadar's monthly median, so 30 tablets cost a pharmacy roughly 54 cents to buy. Our price pages track those benchmarks for 47 common generics.
Fixed per-fill costs add up
Every fill carries costs that do not depend on how many tablets are in the bottle. Federal Medicaid rules list them in the definition of a professional dispensing fee5: the pharmacist's time checking coverage, utilization review, filling the container, counseling and overhead. New Jersey Medicaid paid $10.92 per prescription6 for that work in the quarter ending September 2026, on top of ingredient cost. Three 30-day fills carry the fee three times; one 90-day fill carries it once. Retail cash prices are set differently, but the same logic often shows through.
On the phone
Phone quotes go best when the caller is brief and exact, and GxRadar's guide to comparing pharmacy cash prices covers what to line up first. A simple opening:
"Hi, I'm comparing prices for a prescription. Could you tell me your cash price for [drug name], [strength], [dosage form], quantity [number]? And if I gave you my insurance, could you check what my copay would be?"
Some pharmacies will run an insurance price only once they have the prescription. Ask for the cash price on the call and the insurance price at transfer or drop-off. GxRadar's pharmacy finder lists pharmacies by ZIP code.
After the fill
Check that the drug name, strength and quantity on the label match the quote. A generic tablet that looks different from last time is worth mentioning to the pharmacist. FDA requires a generic to match the brand in active ingredient, strength, dosage form and route7, but not in looks; the agency's consumer guide notes that US trademark law does not allow a generic to look exactly like8 other drugs already on the market. A change of manufacturer is one common reason, as our piece on why your pill changed color explains, and the pharmacist can confirm what was dispensed. Knowing the maker also helps if a lot later appears on FDA's recall list.
Keep the receipt or the note. Generic acquisition costs move from week to week in the NADAC data, and the next refill is another chance to ask.
