What Verisim Health is
Verisim Health creates synthetic healthcare member records calibrated to public benchmarks, with Medicare Advantage available now. Its web-based panel includes eligibility and enrollment, medical and pharmacy claims, revenue and payment, encounters, laboratory results, admission, discharge and transfer events, and member journeys. Records across these files connect through member_id and share an underlying synthetic clinical history, so they can be used together for internal analytics, benchmarking, research, model development and validation, software development, testing, and product demonstrations. Each dataset comes with a credibility audit comparing its metrics with cited public benchmarks. The records are computer-generated and contain no real patients, PHI, or information derived from actual individuals or claims. The free sample covers 5,000 members for 2024–2026 across all eight domains and includes a full report bundle; the 24 MB download is available as Parquet or CSV, with Parquet as the default. The Complete panel provides 100,000 members for the same period and domains, also with the report bundle, for $5,000 one-time per release. Data reflects aggregate national benchmarks rather than the specific characteristics of an individual plan. Commercial, Medicaid, ACA, and Medicare FFS offerings are described as roadmap or expanding lines of business.
Who it suits
Verisim Health is intended for payers, providers, value-based-care teams, health-tech companies, and actuaries who need synthetic Medicare Advantage records for analytics, research, development, testing, or demonstrations. Its benchmark audit and connected data domains may suit teams that want to evaluate workflows without using real patient records.
