Financial instrument which may be used to reimburse or pay for health care products and services. Includes both insurance and self-payment.
The Coverage resource is intended to provide the high-level identifiers and descriptors of an insurance plan, typically the information which would appear on an insurance card, which may be used to pay, in part or in whole, for the provision of health care products and services.
This resource may also be used to register 'SelfPay' where an individual or organization other than an insurer is taking responsibility for payment for a portion of the health care costs. Selfpay should not be confused with being a guarantor of the patient's account.
The Coverage resource is an "event" resource from a FHIR workflow perspective.
