Medicare Part D spending
CMS's Medicare Part D spending dataset reports gross spending on Bosulif of $235.31 million in 2024, across 15,541 claims and 1,981 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 | $235.31 million | 15,541 | 1,981 | $15,141 |
| 2023 | $199.14 million | 12,955 | 1,732 | $15,371 |
| 2022 | $170.02 million | 12,137 | 1,628 | $14,009 |
| 2021 | $147.66 million | 11,031 | 1,495 | $13,386 |

Rare-disease (orphan) designations
The FDA's orphan drug database lists 3 designations for bosutinib, 3 with an approval recorded. A designation is not an approval and not a statement that the drug treats the condition; the status column is the database's own.
| Designated | Designated use | Status | Sponsor |
|---|---|---|---|
| February 24, 2009 | Treatment of chronic myelogenous leukemia | Designated/Approved | PF PRISM C.V. |
| February 24, 2009 | Treatment of chronic myelogenous leukemia | Designated/Approved | PF PRISM C.V. |

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 8 states with the largest reimbursement are shown. 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 |
|---|---|---|---|
| FL | 79 | $1,558,455 | Fee-for-service only |
| NC | 70 | $1,389,933 | Fee-for-service only |
| TX | 75 | $1,279,886 | All record types |
| IL | 54 | $989,507 | All record types |
| IN | 62 | $983,791 | All record types |
| KY | 53 | $961,726 | Fee-for-service only |
| AZ | 53 | $754,649 | Fee-for-service only |
| CT | 47 | $728,224 | All record types |
Where the publisher suppresses small managed-care cells, a state's figure covers fee-for-service claims only and understates use (4 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. 16 older-year figures are held and left out of the table.

Medicaid spending
CMS's Medicaid spending dataset reports $58.04 million for Bosulif in 2024. CMS's dataset states spending includes Federal and State reimbursement and dispensing fees and is not reduced by Medicaid rebates paid to the states. Spending is what Medicaid paid, not what a patient pays.
| Year | Spending | Claims |
|---|---|---|
| 2024 | $58.04 million | 3,407 |
| 2023 | $55.67 million | 3,404 |

Federal formulary status
TRICARE
The Defense Health Agency's TRICARE formulary files include 2 packages of Bosulif in the uniform formulary class LEUKEMIA AND LYMPHOMA AGENTS. Each row counts packages by the list that names them and the status it gives. A status is a TRICARE listing, not a statement about what a plan will pay for you.
| List | Status | Packages |
|---|---|---|
| Non-Formulary Drug List | NON-FORMULARY | 2 |
| Tier 4 / Not Covered Drug List | NOT COVERED | 2 |

VA national formulary
The VA's national formulary files list the ingredient bosutinib, which covers every maker's product with that ingredient, not only Bosulif. Each row is a VA national drug file entry and its status.

Questions
Does Medicare have a negotiated price for Bosulif?
The CMS negotiated-price file we read does not list Bosulif, so this page shows no negotiated price. A drug appears in that file only when CMS selects it for negotiation, and not being listed says nothing about what it costs a patient.
Is there help paying for Bosulif?
No program in our finder currently lists it as open to new patients. Pfizer RxPathways lists the products that remain in its Patient Assistance Program as of January 1, 2026, and marks Xeljanz and Bosulif as taking no new patients starting July 1, 2026. The page also notes the product list is subject to change.
