CMS Open Payments vs Definitive Healthcare: Side-by-Side Comparison
CMS Open Payments (the Sunshine Act database) is the federal disclosure of payments from pharmaceutical manufacturers and device companies to physicians and teaching hospitals — free, annual, and publicly searchable. Definitive Healthcare is an enterprise commercial platform that layers go-to-market intelligence on top of federal foundations including Open Payments. They serve different purposes: one is a disclosure requirement, the other is a commercial intelligence product.

Which platform fits your team
When to use CMS Open Payments
Use CMS Open Payments when the goal is financial relationship disclosure — looking up what a physician received from a pharma or device company, building a conflict-of-interest review, or researching Sunshine Act compliance. The data is free, federal, and annually published.
When to use Definitive Healthcare
Use Definitive Healthcare when the goal is commercial go-to-market intelligence — territory planning, facility targeting, and executive outreach. Open Payments may appear as one input in Definitive's provider profiles, but the commercial value is in the intelligence layers above it.
Common questions
- Is CMS Open Payments the same as the Sunshine Act?
- Yes. CMS Open Payments is the database mandated by the Physician Payments Sunshine Act (Section 6002 of the ACA). Manufacturers and GPOs with products covered by Medicare, Medicaid, or CHIP must report all payments and other transfers of value to physicians and teaching hospitals annually.
- Does Definitive Healthcare include Open Payments data?
- Definitive Healthcare is likely to incorporate CMS Open Payments as one of its inputs, but its specific data sourcing and field-level methodology are proprietary and not publicly documented. The Open Payments data itself is freely available at openpaymentsdata.cms.gov.
- Can Open Payments data be used to identify conflicts of interest in research?
- Open Payments is widely used in academic research to study financial relationships between industry and physicians. Because the data is publicly available, annually updated, and NPI-keyed, it can be independently downloaded and analyzed. Researchers should note the annual publication lag — CY data is typically published roughly 5 months after calendar year-end.
- What fields are in CMS Open Payments?
- Key fields include the physician's NPI and name, the reporting entity, payment amount, payment nature (consulting fee, travel, food, research grant, etc.), and the associated drug or device. Fonteum ingests Open Payments annually and cross-resolves payment records against NPPES for provider identity joins.
