In an article for Health Affairs, James C. Robinson argues that the US should take a page from Germany to drive competition among pharmaceutical companies and to lower drug costs for individuals. Medicare and other insurers should pay a fixed fee for drugs with the same clinical benefits, regardless of their cost, and leave it to individuals to decide which drug to get. Ideally, drug manufacturers with costlier drugs would be forced to bring down their prices in order to compete effectively.
It seems insane that drug manufacturers can charge very different prices for drugs that are similar in effect, and that Medicare and other insurers will pay more for drugs that are no more efficacious than less expensive drugs.
In Germany, when there are three or more drugs that are equally effective, they are treated as if they are in the same therapeutic class. They might be brand name or generic or both. The insurer then pays no more than a particular price for all these drugs, which the insurers collectively set.
Patients have a powerful financial incentive to choose the lowest-priced drugs when they offer similar clinical benefits as the higher-priced drugs. Patients must pay whatever the difference in cost for the higher-priced drugs. Generally, this leads the manufacturers of the higher-priced drugs to reduce their prices.
Insurers in Germany are generally able to negotiate additional discounts on a single drug in that class through a confidential rebate system with the manufacturer of that drug. The manufacturer wins with more business; consumers win with lower prices.
For the German reference pricing system to work best, there need to be several drugs in a class. So, the German government broadened therapeutic classes for biologics and biosimilars, where there are otherwise too few drugs to promote competition.
The system in the US does not begin to work as well for several reasons. The authors focus on the fact that all drugs in a therapeutic class tend to cost consumers around the same coinsurance amount, so pharmaceutical companies don’t benefit from bringing down their prices. Moreover, the coinsurance amount can be so high that patients are forced to skip filling their prescriptions.
The US drug pricing system is inequitable, discriminating against people with lower incomes. People pay too much for drugs that are fairly priced and not enough for drugs that are overpriced.
Why shouldn’t drugs be priced in keeping with their value so that manufacturers set fairer prices and patient’s can more easily afford them. Higher out-of-pocket costs should accompany drugs that are priced above their clinical value. Drugs should be easily affordable to people when they are priced at their clinical value.
Insurers in the US have not used reference pricing for drugs for two principal reasons. Pharmacy Benefit Managers, the middlemen who buy drugs from pharmaceutical companies and design and administer insurer formularies don’t like it. Reference pricing would eat into the enormous profits they make from rebates they get from manufacturers to list their high-priced drugs on a formulary at a low out-of-pocket cost. And purchasers worry that they take a risk with reference pricing that they don’t want to take.
But, insurers should test reference pricing on biologics and biosimilars with the same clinical value. Patients would then pay less for lower-priced drugs and more for high-priced drugs that are not superior. The result could yield significant savings and help ensure people can afford their drugs.
