 ### Conventions 
   * Different Payers have different designs for their health benefit Plans. The PAYER_PLAN_PERIOD table does not capture all details of the plan design or the relationship between Plans or the cost of healthcare triggering a change from one Plan to another. However, it allows identifying the unique combination of Payer (insurer), Plan (determining healthcare benefits and limits), Sponsor (holds the financial risk), Family and Person. Typically, depending on healthcare utilization, a Person may have one or many subsequent Plans during coverage by a single Payer.
-  * **sponsor:** who finances the transaction. **payer:** who administers the transaction. **plan:** the actual contract being administered by the payer and agreed by the sponsor. **stop reason:** reason for termination of the contract

   * Source values of the Payer, Plan, Sponsor, Family are captured as the respective _source_value. Concept_id's are used to support standardized analysis, similar to other OMOP CDM tables that use _source_concept_id and _concept_id.
   * Typically, family members are covered under the same Plan as the Person. In those cases, the payer_source_value, plan_source_value and family_source_value are identical
