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 |
|---|---|---|
| MerckBelsomra | $368 | $27,33259 claims |
| Otsuka America Pharmaceutical, Inc.Rexulti | $663 | $25,95918 claims |
| Takeda Pharmaceuticals U.S.A., Inc.Trintellix, Vyvanse | $706 | $22,92149 claims |
| ITI, Inc. (d/b/a Intra-cellular Therapies, Inc.)Caplyta | $1,742 | $22,89014 claims |
| Eisai Inc.Dayvigo | $272 | $13,65828 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. Against peers, this provider's reported payments sit in the 90th percentile of 4,954 psychiatry providers in California.
