# Coverage

> Schema documentation for the Coverage table in the Metriport data model

Financial instrument which may be used to reimburse or pay for health care products and services. Includes both insurance and self-payment.

**Reference Table:**

The `coverage_references` table contains normalized references from the coverage to other entities. It supports the following reference properties:

* **beneficiary** (required): links to the patient who is the beneficiary of the coverage
* **payor**: links to the organization or patient responsible for payment
* **policyHolder**: links to the owner of the insurance policy
* **subscriber**: links to the subscriber to the insurance policy

For detailed information about reference table structure and indexing, see the [Reference Tables documentation](/medical-api/handling-data/schema-v000/reference-tables).

**Coverage Table:**

**Primary Keys:**

* coverage\_id

**Foreign Keys:**

* patient\_id
