Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.

How this compares
Too few hematology-oncology providers in New Jerseyto place this figure against a meaningful peer group, so we don't.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| ImbruvicaIbrutinib | 25 | $401,933 |
| PomalystPomalidomide | 16 | $332,897 |
| IbrancePalbociclib | 21 | $326,557 |
| RevlimidLenalidomide | 19 | $319,578 |
| XalkoriCrizotinib | 12 | $274,512 |
| VenclextaVenetoclax | 16 | $211,255 |
| BrukinsaZanubrutinib | 12 | $173,333 |
| Lenalidomide | 11 | $125,156 |

| Imatinib Mesylate | 38 | $31,838 |
| Anastrozole | 170 | $4,154 |
| Letrozole | 138 | $3,187 |
| Exemestane | 26 | $3,139 |
| Hydroxyurea | 52 | $1,768 |
Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| E.r. Squibb & Sons, L.L.C.Pomalyst | $16,404 | $332,89716 claims |
| Bristol Myers SquibbRevlimid | $31 | $319,57819 claims |
| AbbVieVenclexta | $490 | $211,25516 claims |
| Johnson & JohnsonXarelto | $97 | $47,52341 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. There are too few hematology-oncology providers in New Jerseyon file to place this against a meaningful peer group, so we don't.
