Specialty Pharmacy

A specialty pharmacy is a pharmacy that dispenses high-cost, high-complexity medications requiring special handling, cold-chain logistics, injection or infusion support, or intensive patient monitoring. Most specialty drugs — biologics, injectables, oral oncology, MS therapies, hepatitis C regimens — can only be dispensed through a limited network of specialty pharmacies, not through your local CVS or Walgreens.

The economics are concentrated. A handful of specialty pharmacies — CVS Specialty (owned by CVS Health), Accredo (owned by Cigna/Express Scripts), Optum Specialty (owned by UnitedHealth) — dominate the market, and each is tied to a major PBM. This vertical integration means the same company often owns the PBM setting the formulary, the specialty pharmacy dispensing the drug, and often the plan itself. Self-funded employers can carve out specialty pharmacy to an independent provider (AllianceRx, Onco360, and others), which frequently produces savings of 15 to 30 percent on specialty spend. Manufacturer-mandated limited distribution networks constrain how much independence a plan actually has on some products.

The takeaway: if you're on a specialty medication, ask what your options are for specialty pharmacy — you're often not locked into one. If you're a self-funded employer, audit the specialty pharmacy arrangement separately from the main PBM contract. The spend concentration is worth the attention.
