Cresemba averages $3,441.00 per Medicare Part D claim — roughly equivalent to a 30-day supply for most patients on standard dosing. Without insurance, expect higher cash-pay prices unless you use a discount program (GoodRx, SingleCare, manufacturer copay assistance). With Medicare or commercial insurance, your out-of-pocket cost depends on your plan's formulary tier and deductible status.
A typical 30-day supply of Cresemba reflects in our Medicare Part D average of $3,441.00 per claim. Switching to generic Isavuconazonium typically reduces cost by 80-95%. Cash-pay prices vary by pharmacy — comparison shopping (or using GoodRx coupons) often saves 20-50% off the listed price.
Most commercial insurance plans and Medicare Part D plans cover Cresemba, but coverage varies by formulary tier. Insurers typically prefer generic Isavuconazonium (Tier 1, lowest copay) over brand-name Cresemba (Tier 2-3, higher copay). Some plans require prior authorization or step therapy. Check your plan's formulary or call the number on your insurance card to confirm.
Several options for cash-pay patients: (1) Manufacturer patient assistance programs — the manufacturer may offer copay cards or free-drug programs for income-qualified patients; (2) Discount programs like GoodRx, SingleCare, or RxSaver typically save 20-80% off the cash price; (3) Mark Cuban's Cost Plus Drugs offers transparent generic pricing if a generic is available; (4) 340B-eligible community health centers offer drugs at federally negotiated discounts. Switching to generic Isavuconazonium is the single biggest cost reducer if your prescriber is open to it.

Reading Cresemba's Medicare Pricing
At $3,441.00 per Medicare Part D claim, Cresemba sits in specialty-drug territory — the price band occupied by biologics, injectables, and narrow-population treatments rather than everyday maintenance pills. Costs at this level usually trace to complex manufacturing, a patient population too small to spread fixed R&D across millions of scripts, or a class with no generic or biosimilar competition yet. For a drug treating infections, that price is the single biggest lever on out-of-pocket exposure, which is why coverage tier and assistance eligibility matter far more here than for a commodity generic.
Medicare spent $234.0M on Cresemba across 68,000 claims and 7,800 beneficiaries — a mid-size line item. Drugs in this tier rarely make headlines but collectively make up the bulk of Part D spending. The interplay between the $3,441.00 average claim cost and the claim volume is what decides whether this drug's total trends up or down year to year.
Because a generic version of Isavuconazonium is on the market, the realistic savings path for Cresemba is straightforward: the generic is therapeutically equivalent and typically costs a fraction of the brand. The friction is usually prescribing habit rather than availability — patients can ask the prescriber to write for the generic, and most plans already steer to it with a lower copay tier. That single switch usually beats coupons, assistance programs, and pharmacy shopping combined.
Every figure here comes from the CMS Medicare Part D Drug Spending dashboard, which reports what the program paid — not the cash price at a retail pharmacy and not a patient's out-of-pocket cost. List prices also overstate the real economics: manufacturers pay confidential rebates to pharmacy benefit managers, so the net price plans actually pay is often well below the sticker. Treat $3,441.00 as a consistent Medicare-program benchmark for Cresemba, useful for comparing drugs on the same basis, rather than the price any one patient will see at the counter.
