Built on the authoritative federal record
The primary sources, named on every page.
These are the federal agencies whose public datasets Fonteum ingests and attributes — the issuing authorities, not customers or partners. Every figure on the site links back to one of them.

Reproducible by design
Every figure traces to its federal source.
14-tuple provenance
Every rendered fact ties to a source URL, dataset ID, snapshot date, row key, and SHA-256 — the full chain-of-custody record.
Reproducible SQL
Each study ships the exact query behind its figures, run against the cited federal snapshot. Re-run it yourself.
Daily reconciliation
Published counts are reconciled against the upstream federal datasets on a daily cadence, with drift logged.
Named medical review

The substrate, by the numbers
Cross-source identity
National Provider Identifier 1003809435 as it appears in every federal dataset Fonteum holds. Each row is a distinct public source; the chip carries the source and the snapshot date behind that field — the record-level form of the source-provenanced graph.

Industry payments
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.
| Nature of payment | Amount | Records |
|---|---|---|
| Food and Beverage | $2,998 | 131 |
| Manufacturer | Amount | Records |
|---|---|---|
| Pfizer Inc. | $326 | 15 |
| Celgene Corporation | $247 | 10 |
| Novartis Pharmaceuticals Corporation | $178 |
Prescribing
Prescriptions written under Medicare Part D, aggregated by drug across the program. Totals reflect claims paid, not patients treated.
| Drug | Claims | Drug cost |
|---|---|---|
| Revlimid(Lenalidomide) | 91 | $1,606,482 |
| Pomalyst(Pomalidomide) | 40 | $795,603 |
| Cabometyx(Cabozantinib S-Malate) | 20 | $562,428 |
| Xtandi(Enzalutamide) | 37 | $525,400 |
| Imbruvica(Ibrutinib) | 29 | $448,774 |
Beneficiary counts below 11 are suppressed by CMS — the total shown is a lower bound.
Quality
CMS Quality Payment Program Merit-based Incentive Payment System (MIPS) final score, where this clinician participated. Absence of a score is not a quality signal — many clinicians report through a group or are exempt.
Enrollment & sanctions
Screening aid — re-confirm any match against the issuing list before acting. A clean result means no record was found in the federal OIG LEIE or the state Medicaid lists Fonteum currently holds (NY, OH, GA), not a guarantee that none exists elsewhere. Not a legal or credentialing certification.
Ownership & affiliations
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.
Record history
Every field on this record is stored bitemporally — both when the fact was true in the world and when Fonteum recorded it. Open the time-travel view to reconstruct this record as of any past date, or to read each field with the source and dates behind it.
