First, CVS Health pulled tobacco from its store shelves. Now it plans to make some customers think twice about filling prescriptions at other stores that sell smokes.
The nation’s second-largest drugstore chain is developing a new tobacco-free pharmacy network that it will offer as a choice to employers and other clients of its Caremark pharmacy benefits management business. Employers, insurers, and unions hire pharmacy benefits managers, or PBMs, to run their prescription coverage.
The new CVS network will slap an extra copayment on patients who fill their prescriptions at stores that sell tobacco. That payment will not apply to prescriptions filled at stores in the tobacco-free network, which would include CVS and Target or other stores that do not sell tobacco. Target Corp. quit selling tobacco in 1996.
The network, which starts next year, comes as companies continue to seek ways to control health care costs that have grown faster than inflation for years. They added wellness programs to help workers become healthier by losing weight or quitting smoking, and are trying to rein in spending by making workers pay a greater share of the cost of their care at doctor’s offices and pharmacies.
CVS spokeswoman Carolyn Castel said her company developed the new PBM network after several customers asked for it. The company’s prescription drug networks cover about 65 million people as the nation’s second-largest PBM, but the tobacco-free option will only be used by the PBM customers that choose it. Castel said it is too early to say how many PBM clients will sign up.
‘‘It’s not across the board,’’ she said, adding that the size of the extra copayment will vary according to client.
A relatively small number of benefits providers will probably try the new option, said Adam J. Fein, president of the business research firm Pembroke Consulting.
More PBMs in recent years have started offering networks that have different copayments depending on pharmacy costs or quality measurements. But a tobacco focus is untested and no one knows if it will have any impact on smoking rates. And companies try to avoid being too disruptive with changes to the benefits they offer.
Even so, Fein called the network a worthwhile experiment because smoking-related illnesses are at the root of a lot of health care costs.
CVS started taking on tobacco in February when it announced that it would remove cigarettes, cigars, and other like products from its more than 7,700 drugstores nationally to help sharpen its focus on health. It completed that task in September when it also announced that it would change its name to CVS Health from CVS Caremark.
Drugstore chains, grocers, and big retailers like Target have delved deeper into customer health in recent years, in part to serve the aging baby boom generation and the millions of uninsured people who are expected to gain coverage under the federal health care overhaul. They have added walk-in clinics to their stores, expanded the care they provide, and put more health care products on their shelves.
CVS Health rivals Walgreen Co. and Rite Aid Corp. still sell tobacco in their drugstores. The new pharmacy benefits network, first reported by The Wall Street Journal, could steer patients away from the competition for CVS. But Fein does not see that as an antitrust concern or anything that creates an unfair competitive advantage.
‘‘No one is forcing an employer to set up a plan that eliminates pharmacies that sell tobacco. It’s just an option,’’ said Fein, who also writes a blog on pharmaceutical economics called Drug Channels.
Shares of CVS Health climbed $1.43 to close at $82.92 Tuesday and have advanced about 25 percent since the company initially announced its split with tobacco in February. That more than doubles the rise of the Standard & Poor’s 500 index over the same span.
