CodeSystemDisplayDefinition
  deny-overrideshttp://hl7.org/fhir/permission-rule-combiningDeny-overrides

The deny overrides combining algorithm is intended for those cases where a deny decision should have priority over a permit decision.

  permit-overrideshttp://hl7.org/fhir/permission-rule-combiningPermit-overrides

The permit overrides combining algorithm is intended for those cases where a permit decision should have priority over a deny decision.

  ordered-deny-overrideshttp://hl7.org/fhir/permission-rule-combiningOrdered-deny-overrides

The behavior of this algorithm is identical to that of the “Deny-overrides” rule-combining algorithm with one exception. The order in which the collection of rules is evaluated SHALL match the order as listed in the permission.

  ordered-permit-overrideshttp://hl7.org/fhir/permission-rule-combiningOrdered-permit-overrides

The behavior of this algorithm is identical to that of the “Permit-overrides” rule-combining algorithm with one exception. The order in which the collection of rules is evaluated SHALL match the order as listed in the permission.

  deny-unless-permithttp://hl7.org/fhir/permission-rule-combiningDeny-unless-permit

The “Deny-unless-permit” combining algorithm is intended for those cases where a permit decision should have priority over a deny decision, and an “Indeterminate” or “NotApplicable” must never be the result. It is particularly useful at the top level in a policy structure to ensure that a PDP will always return a definite “Permit” or “Deny” result.

  permit-unless-denyhttp://hl7.org/fhir/permission-rule-combiningPermit-unless-deny

The “Permit-unless-deny” combining algorithm is intended for those cases where a deny decision should have priority over a permit decision, and an “Indeterminate” or “NotApplicable” must never be the result. It is particularly useful at the top level in a policy structure to ensure that a PDP will always return a definite “Permit” or “Deny” result. This algorithm has the following behavior.

Explanation of the columns that may appear on this page:

LvlA few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
