An example mapping of Health Plan data for Members to the US Core Encounter profile is shown below:

When populating the encounter resource period - if claim has period, populate period; if only a date, populate the end date in a period element.

The essential fields (Must Support or Cardinality greater than 0..*) to be provided in the US Core Encounter resource are:
