Many hospitals that participate in the 340B Drug Pricing Program faced a dilemma as their Medicaid census fell or was projected to fall below the qualifying percentage. They used what appeared to be a loophole that allowed them to still qualify. This subset of hospitals – those that reclassified as “rural” to preserve or regain eligibility – also found a nasty and often misunderstood reimbursement squeeze.
Why Reclassifying as Rural Became a 340B Survival Strategy
Hospitals have long pursued rural reclassification for reimbursement reasons (wage index, payment adjustments, and other strategic positioning). In the 340B context, rural classification lowers the qualifying percentage, which is heavily based on Medicaid census, from 11.75 to 8 percent.
The Orphan Drug Trap for Rural Hospitals
The problem was that hospitals that used the rural reclassification method to stay in the 340B program lost the mandatory discount for “orphaned drugs.” You would think with a name like orphaned drugs, the impact would not be a huge issue; sadly for these hospitals, it can cut the 340B benefit by as much as 30 percent.
For the purposes of the 340B Drug Pricing Program, an orphan drug is any drug that has received said designation from the Food and Drug Administration (FDA) under the Orphan Drug Act.
That designation is granted when a drug is intended to treat:
- A rare disease or condition affecting fewer than 200,000 people in the U.S.; or
- A disease affecting more than 200,000 people where there is no reasonable expectation that development costs will be recovered through U.S. sales.
Under 340B’s orphan drug provisions, certain covered entity types are prohibited from purchasing orphan drugs at 340B prices when those orphan drugs are used for non-orphan indications.
How Reimbursement Turns into a Margin Hit
The biggest-ticket orphan/rare-disease drugs right now include:
These are one-time gene therapies costing millions of dollars, the “single patient, single event” budget busters:
- Lenmeldy (atidarsagene autotemcel) — wholesale acquisition cost (WAC) $4.25 million (one-time);
- Hemgenix — widely reported at ~$3.5 million list/WAC (one-time);
- Elevidys — WAC $3.2 million (one-time);
- Skysona — ~$3.0 million (one-time);
- Zolgensma — WAC $2.125 million (one-time); and
- Itvisma (Novartis; SMA gene therapy, newer) — Reuters reported WAC $2.59 million.
Why these matter to a rural referral center (RRC): even if these aren’t “high-volume,” a single case can create a huge spread risk if reimbursement is delayed/denied or if your acquisition is close to WAC and you don’t have 340B economics available.
There are also the steady margin-grinders in infusion/specialty, chronic “forever drugs” with a very high annual cost:
- Soliris (eculizumab) — commonly cited as > $500,000/year and sometimes higher, depending on indication/dosing;
- Ultomiris (ravulizumab) — published economic tables show ~$474,000–$569,000 annual drug cost depending on weight/dosing assumptions;
- Crysvita (burosumab) — published sources show adult annual drug costs commonly in the ~$454,000–$584,000 range (and pediatric use can vary widely by weight/dose); and
- Evrysdi (risdiplam) — list pricing is weight-based and capped around $340,000/year.
What Smart Hospitals Can Do Next
Hospitals navigating such a scenario typically focus on four moves:
- Quantify orphan-drug exposure by National Drug Code (NDC), clinic, and payer;
- Model reimbursement spread under 340B vs. non-340B acquisition;
- Tighten split-billing logic and contract pharmacy policies to avoid unnecessary carveouts; and
- Align medical staff and pharmacy operations so prescribing, dispensing site, and purchasing strategy work together.
