A claim is generated every time you receive a service covered by the group health insurance program. This ranges from a health care visit to filling a prescription drug. The claim contains standardized codes for each service, and includes such information as the date of the service, and service provider name and location (e.g., physician, facility). This information is like the “Explanation of Benefits” you may receive in the mail after visiting your health care provider. The claims data also provides payment information such as the amount billed by the provider, deductible, copayment or coinsurance amounts, and the amount the insurer paid to the provider for the services rendered.
