Medicare Part D spending
CMS's Medicare Part D spending dataset reports gross spending on Vyvgart Hytrulo of $126.10 million in 2024, across 2,394 claims and 658 beneficiaries. CMS's dataset states spending is gross drug cost and does not reflect manufacturers' rebates or other price concessions. Spending is the total paid by Medicare, plans and beneficiaries for the drug's claims, not what a patient pays.
| Year | Gross spending | Claims | Beneficiaries | Average spending per claim |
|---|---|---|---|---|
| 2024 | $126.10 million | 2,394 | 658 | $52,674 |

Medicare Part B payment limit
CMS publishes a quarterly payment limit for the HCPCS code that its NDC crosswalk links to Vyvgart Hytrulo. It is a ceiling for providers who bill Medicare Part B, not a price a patient pays, and a code's presence says nothing about whether Medicare covers a product.
| HCPCS code | Quarter | Payment limit | Per dosage descriptor | Effective | Read |
|---|---|---|---|---|---|
| J9334 | 2026 Q4 | $33.59 | 2 MG | October 1, 2026 through December 31, 2026 | November 7, 2026 |

Medicaid use by state
CMS's State Drug Utilization Data records, for 2025, how many prescriptions each state's Medicaid program paid for under this drug's packages and what it reimbursed. The 10 states with the largest reimbursement are shown of 12 with data. Reimbursement is before the rebates manufacturers pay states, so it is not a net cost and not a price a patient pays.
| State | Medicaid-paid prescriptions | Medicaid reimbursed | Covers |
|---|---|---|---|
| CA | 191 | $10,578,589 | Fee-for-service only |
| NC | 186 | $6,921,786 | All record types |
| NY | 291 | $5,290,759 | Fee-for-service only |
| NJ | 272 | $4,629,202 | All record types |
| IN | 214 | $3,694,892 | All record types |
| VA | 123 | $3,432,626 | All record types |
| FL | 72 | $2,245,591 | Fee-for-service only |
| OH | 75 | $1,987,058 | Fee-for-service only |
| PA | 91 | $1,507,990 | All record types |
| MI | 74 | $1,424,313 | Fee-for-service only |
Where the publisher suppresses small managed-care cells, a state's figure covers fee-for-service claims only and understates use (7 state and package figures are marked that way here). A state missing from the table means its figures were suppressed or not reported, not zero use. 1 older-year figure is held and left out of the table.
