Source: CMS Open Payments PY2024 (Sunshine Act) — https://openpaymentsdata.cms.gov/
Falsifier: A RECORD of measured/reported events (occurred=true) from CMS Open Payments PY2024 (Sunshine Act); superseded when CMS Open Payments PY2024 (Sunshine Act) publishes its next release.

### Payment composition: promotional vs royalty vs other

**INTERPRETATION.** Of that, $12,934 is promotional (meals, speaking, travel, consulting — a company marketing its products), $1,715,635 is royalty/ownership (income for inventing or owning something, not a prescribing conflict), and $0 is research/grants/other.

Falsifier: occurred=FALSE (a framing, not an event) and adjudged=FALSE (an in-house reading, not an authority's verdict) — the LOWEST-warrant claim here. A flat representation would render this identically to the official facts; the four-status does not.

### Largest paying companies (in-house ranking over CMS records)

**DERIVED.** Largest paying companies: Stryker Corporation ($1,728,427), Zimmer Biomet Holdings, Inc. ($445,148), Smith+Nephew, Inc. ($50,000), Medacta USA, Inc. ($141). The company names and per-payment amounts are CMS-recorded; the "largest" ranking and selection are an in-house aggregation, so adjudged=FALSE — CMS did not adjudge this ranking.

Falsifier: occurred=FALSE (a calculation, not an event) and adjudged=FALSE (a transparent in-house formula, not an authority's verdict — no external adjudicator). Reproduce it from its named inputs; falsified if the formula or inputs are wrong. Lower warrant than the adjudged figures above.

### What an Open Payments figure is — and is NOT

**INTERPRETATION.** A disclosed Open Payments amount is a publicly-reported financial relationship; it is not proof of wrongdoing and not evidence it changed patient care. It is not a rating of this physician.

Falsifier: occurred=FALSE (a framing, not an event) and adjudged=FALSE (an in-house reading, not an authority's verdict) — the LOWEST-warrant claim here. A flat representation would render this identically to the official facts; the four-status does not.
