This article is based on a recent personal experience with a health insurance company. As a physician, I believe this “interaction” may represent anything from poor customer service to a potentially questionable business practice. If your health insurance helps pay for your medications, this story may be relevant to you.
The situation
My health insurance covers prescription medications, subject to a copayment for each prescription. In 2024, my copayment for a particular medication was $0. In 2025, it increased to $15 per refill. Then, in 2026, it suddenly jumped to $95 per refill.
The insurance company’s explanation was that the medication had been reclassified from Tier 1 (commonly used, lower-cost generic medications) to Tier 3 (typically higher-cost or brand-name medications). No clear or convincing explanation was provided for this change.
What made the situation even more puzzling was that the medication remained widely available as a generic drug and had not experienced a significant price increase.
An unexpected solution
Rather than paying the $95 copayment, I declined to fill the prescription through the insurance company’s preferred pharmacy. Instead, I transferred the prescription to another pharmacy and used a GoodRx coupon.
The result? The exact same medication costs $12 out of pocket.
In other words, by stepping outside the insurance company’s preferred pathway, my out-of-pocket cost dropped from $95 to $12.
What should we make of this?
I am not an attorney and cannot say whether this practice is illegal. It may simply reflect the complex economics of today’s health insurance and pharmacy benefit systems. Nevertheless, it raises an important question:
How can a medication cost a patient $95 through insurance but only $12 when purchased directly with a discount coupon?
My purpose in sharing this experience is to encourage consumers to be informed, ask questions, and compare options. Sometimes the lowest-cost solution may not be the one your insurance plan initially presents.

Great info, Charlie
It seems counterintuitive, but it happens quite often in the U.S. healthcare system. A few reasons explain why a medication might cost $95 through insurance but only $12 with a discount coupon:
Insurance negotiated price vs. coupon price
Your insurance company has a contracted price with the pharmacy or pharmacy benefit manager (PBM).
That negotiated price isn’t always the lowest available cash price.
Discount programs may use a completely different pricing arrangement.
Deductible hasn’t been met
If you’re paying toward an annual deductible, you may be responsible for the full negotiated cost of the medication until the deductible is satisfied.
The coupon price can be lower than what insurance applies to your deductible.
Drug formulary tiers
Insurance plans place medications into tiers with different copays or coinsurance amounts.
A drug on a higher tier may have a large copay even if the actual cash price is relatively low.
Pharmacy Benefit Managers (PBMs)
PBMs act as middlemen between insurers, drug manufacturers, and pharmacies.
Their pricing and rebate arrangements can create situations where the insured price is surprisingly higher than a discount-card price.
When a long-established generic medication hasn’t experienced a significant wholesale price increase, yet the insured price is far higher than the cash price with a coupon, the explanation often lies in the drug pricing system itself rather than the manufacturer’s price.
Everyone lines their pocket as much as they can. It’s a profit business, unfortunately.
For those who are uninsured, they find out in due time, that there is a two tier system. For example, an in hospital stay, dr visit, outpatient dpsirgery, etc. The charges billed will almost always be a lot less when paying cash versus utilizing an insurance card. I discovered this over 15 years ago when facing a routine outpatient procedure. I’ve also worked as a claims processor over the years. Been retired for a while now, but sadly, not much has changed in this pyramid analysis.
Hey Dr. B;
The pricing situation you experienced is pretty common and is typically due to the Pharmacy Benefits Manager the insurance company uses. Most insurance companies don’t price pharmaceuticals because it is so complicated. They rely on the “middle man” or PBM to do that for the insurance co. My pharmacy makes it easy for me and determines for me if it’s cheaper to use my insurance or to apply a “coupon” like GoodRX to the drug. There are lots of these coupon programs and my pharmacy checks multiple options and I pay the lowest cost they can find. Even if that’s not through my insurance – and it’s usually not by using my insurance – for generics. It’s a bit different for brand drugs that are not yet available as a generic. You will find that companies who don’t generate their main revenue streams from prescription drugs have more flexibility to offer patients the lowest cost option even if it’s not through the patients insurance company or PBM. These types of pharmacies are typically associated with retailers or grocery stores where the pharmacy services are offered as a convenience for their customers and to get the customer in the store to buy the stores main line of products. You won’t find this same flexibility at national pharmacy chain stores usually. Hope this information is helpful. I enjoy your column.
