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.
