Payer Data - synthetichealth/synthea GitHub Wiki

By default, the project contains Payers (i.e. public and private health insurance companies) in the src/main/resources/payers/insurance_companies.csv file, which is a list of some public and private insurers who provide services nationally (US).

The default financial numbers (e.g. premiums and copays) are not accurate.

You can modify the payer file or have Synthea use an alternative payer file by altering the src/main/resources/synthea.properties file:

# Payers
generate.payers.insurance_companies.default_file = payers/insurance_companies.csv

# Payer selection behavior
# How patients select a payer:
#  best_rates - select insurance with best rates for person's existing conditions and medical needs
#  random  - select randomly.
generate.payers.selection_behavior = random
