## Claims

### Total 2024 industry payments to Dr. John Koo

**RECORDED.** In 2024, drug and device companies reported $368,228 in payments to Dr. John Koo (Physician, SAN FRANCISCO, CA) across 366 payments.

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Falsifier: A RECORD of measured/reported events (occurred=true) from CMS Open Payments PY2024 (Sunshine Act); superseded when CMS Open Payments PY2024 (Sunshine Act) publishes its next release.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, $368,228 is promotional (meals, speaking, travel, consulting — a company marketing its products), $0 is royalty/ownership (income for inventing or owning something, not a prescribing conflict), and $0 is research/grants/other.

Source: Atlas Commons grouping of CMS nature-of-payment codes by patient relevance — https://care-atlas.ryanjhunter.workers.dev/
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: AbbVie Inc. ($75,521), Lilly USA, LLC ($49,247), Pfizer Inc. ($44,923), Amgen Inc. ($44,161), E.R. Squibb & Sons, L.L.C. ($42,064). 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.
