CVS Caremark announced that after June 30, it will no longer cover Stelara for most commercial clients and instead cover two ustekinumab biosimilars, including its private-label version of Pyzchiva.
Effective with its July 1, 2026 formulary update, CVS Caremark will officially drop from coverage the ustekinumab reference product Stelara and prefer both Pyzchiva and Yesintek biosimilars. This change applies to “its most common commercial template formularies.”

CVS Caremark clarified to BR&R that its Cordavis private-label version of Samsung Bioepis’ Pyzchiva would be preferred, as well as the original branded Yesintek from Biocon, and not the original branded version of Pyzchiva.
Pyzchiva’s wholesale acquisition cost (WAC) (both he branded and private-label version) is 85%–86% below the original WAC price of Stelara (which is now available at a 75% discount). CVS Caremark stated that there will be $0 consumer cost sharing when either of the two preferred biosimilars are prescribed.
Joshua Fredell, PharmD, Senior Vice President, CVS Health, said, “Expanding adoption of FDA approved biosimilars allows us to deliver significant savings for clients while supporting broader, more affordable access to proven therapies.”
In addition, CVS Caremark noted that the biosimilars Tyruko (reference product, Tysabri) and Epysqli (reference product, Soliris) will also be covered. CVS did not disclose that these two reference products would be excluded from coverage, however. Unlike ustekinumab, natalizumab and eculizumab, are most commonly covered under the medical benefit.
