Industry payments

| Manufacturer | Amount | Records |
|---|---|---|
| Astrazeneca Pharmaceuticals Lp | $62 | 2 |

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.
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.
