Specialty Drug

Specialty drugs are high-cost medications used to treat complex, chronic, or rare conditions — rheumatoid arthritis, multiple sclerosis, Crohn's, cancer, hepatitis C, cystic fibrosis. They typically require special handling (refrigeration, injection, infusion), close clinical monitoring, or prior authorization, and they usually cost more than $1,000 per month. Many are biologics.

Specialty drugs are the story of modern plan spend. They represent about 2 percent of prescriptions but roughly half of total pharmacy spend on most employer plans. A single member on a specialty drug can cost the plan $80,000 to $500,000 per year. Plans manage this through specialty pharmacy networks (limited pharmacies that dispense the drug), site-of-care steering (infusion at home or a freestanding center instead of a hospital, which can cut cost in half), manufacturer patient assistance programs, international sourcing programs, and — for self-funded employers — carve-out specialty PBM arrangements. Stop-loss insurance is critical when a plan has specialty utilizers because a single member can exceed the specific deductible in a month.

The takeaway: if you or a covered family member is on a specialty drug, engage the plan's case management program the day the prescription is written. There are almost always lower-cost paths — assistance programs, site-of-care changes, biosimilar alternatives — but they don't happen automatically.
