Should Specialty Drugs Be Shifted From Medical to Pharmacy Benefit?
Specialty drugs have been a house divided. Oral medications have been managed under the pharmacy benefit while medications that are infused or injected have been managed as a medical benefit. Self-injected medications have been a muddle, landing on both sides of the benefit divide. Common sense and convenience recommended this arrangement. If health plans and other payers were paying providers under the medical benefit for injection and infusion services, why not cover drug being injected or infused as part of the same claim? Besides, specialty drugs have been a secondary concern, so the medical–pharmacy benefit split just hasn’t been that big a deal. Until recently, oral medications have been the category in need of management, and they are clearly the province of the pharmacy benefit, accounting for the lion’s share of pharmacy expenditures. And the oncologists, rheumatologists, and other specialists who regularly prescribe and administer specialty drugs haven’t been complaining. When they buy medications and bill for them, that has added an income stream into their practice. For some, that stream has turned into a torrent as the number and cost of the specialty drugs has increased. Now that specialty drugs have become budget busters, health plan executives and pharmacy benefit managers are questioning the wisdom of covering specialty drugs in two different ways and, more particularly, whether more medications should be moved from the medical benefit to the pharmacy benefit as one way to rein in costs. According to the 10th edition of EMD Serono’s Specialty Digest, the switch is under way. A survey of 91 health plans that provided the data for the digest found a significant shift to the pharmacy benefit for the medications for hemophilia, respiratory syncytial virus, and, as a group, the intravenous immune-modulating medications for rheumatoid arthritis, Crohn’s disease, and psoriasis (figure, below).

The fact is that it has been talked about for years. Patrick Gleason, PharmD, director of health outcomes for Prime Therapeutics, the Minnesota-based pharmacy benefit manager, says there have been fewer changes than all the talk might suggest: “It isn’t so simple. That’s why it hasn’t happened very much.” Four advantages There have been some early adopters, such as Blue Cross & Blue Shield of Rhode Island (BCBSRI). The insurer acted well before the current trend, moving many specialty medications over to the pharmacy benefit six years ago. BCBSRI contracts with Walgreens to supply and help to manage the specialty medications, while Catamaran pays the claims as the pharmacy benefit manager. Control of the formulary stays with the health plan, says Donna Paine, PharmD, MBA, a specialty pharmacy program manager for Blue Cross & Blue Shield of Rhode Island: “It’s our formulary. It’s our criteria for coverage.” Four themes emerge when Paine and others talk about the advantages of moving specialty drugs to the…
