Includes FHIR-36471 which was incorrectly withdrawn.  Update the ext-coverage-information extension to have a 0..* 'detail' component with a name-value pair 'detail' - Additional information that qualifies, describes, or provides additional guidance about coverage or documentation requirements 'code' - 1..1 CodeableConcept - The type of detail or qualification expressed 'value' - 1..1 string, SimpleQuantity, Period, boolean - the detail or qualification that applies to this order 'qualification' 0..1 string - additional text that qualifies/expands on the coded value.  (Only permitted if value is not a string) Extensible value set for codes: allowed-quantity - Indicates limitations on the number of services/products allowed (possibly per time period).  Value should be a Quantity allowed-period - Indicates the maximum period of time that can be covered in a single order.  Value should be a Period in-network-copay - Indicates a percentage co-pay to expect if delivered in-network.  Value should be a Quantity. out-network-copay - Indicates a percentage co-pay to expect if delivered out-of-network.  Value should be a Quantity. auth-out-network-only - Authorization is only necessary if out-of-network.  Value should be a boolean. concurrent-review - Additional payer-defined documentation will be required prior to claim payment.  Value should be a boolean. appropriate-use - Payer-defined appropriate use process must be invoked to determine coverage.  Value should be a boolean.   Will update in the overview the fact that CRD allows payers to convey discrete coverage expectations and attach them to the order.
