Industry payments

Open Payments received

Payments and transfers of value this clinician received from drug and device manufacturers, disclosed under the Physician Payments Sunshine Act. A payment is a disclosure, not a judgment.

Prescribing

Medicare Part D prescribing

Prescriptions written under Medicare Part D, aggregated by drug across the program. Totals reflect claims paid, not patients treated.

Beneficiary counts below 11 are suppressed by CMS — the total shown is a lower bound.

Ownership & affiliations

Graph relationships

One-hop relationships in the resolved entity graph — chain membership, ownership, and operation edges, each backed by a federal source row. Most individual clinicians carry none; edges populate for owners and organizations as the Lane D backfill runs.
