Display of Decision Details

Some data processing for decision details occurs at the time when the determination result was calculated, as described in the previous section.

However, in contrast to eligibility/entitlement and key decision factors, display of decision details also involves some considerable processing, described in this section.

A case worker can choose to view Decision Details in these ways:

• When viewing a determination's list of coverage periods, the user can expand a row for a coverage period, to display the decision details for the first display category configured on the product; and/or
• The user can click on the date range shown for a coverage period to display the full decision details pages, which show a clickable tab for each display category (with the first display category shown by default).

Either of these actions instructs the Engine to display decision details for a particular date and display category on a determination for a case. When instructed, the Engine performs the following steps:

• The Engine looks up the Dynamic UIM page to display, based on the display category requested. The configuration for which page to display is stored on the CREOLEProductDecisionDispCat.displayPageName database column.
• The web server loads the Dynamic UIM page, which will specify an appropriate server interface to call to retrieve data for the screen. The supported server interfaces are as follows:

  Table 1. Supported server interfaces for decision details UIM pages

  Server interface	Description
  CaseDetermination. viewDecisionDisplayRulesCategoryXML	Retrieves XML data for the top-level decision details screen for a single coverage period.
  CaseDetermination. viewDecisionDisplayRuleCategorySubscreenXML	Retrieves XML data for a sub-screen of decision details screen for a single coverage period and business object ID (identifying the sub-screen being expanded).
  CaseDetermination. viewPreviousDecisionDisplayRulesCategoryXML	Retrieves XML data for the case decision period succeeded by the coverage period requested. Typically used in addition to CaseDetermination.viewDecisionDisplayRulesCategoryXML to provide data for a comparison screen.
  CaseDetermination. viewPreviousDeterminationDecisionDisplayRulesCategoryXML	Retrieves XML data for the same period in the determination superseded by the requested determination - reserved for use by Engine screens to compare under/over-payment determinations only.

• The Dynamic UIM page calls its server interface(s) to retrieve XML data for the coverage period.
• The Dynamic UIM page contains XPath-like expressions for querying the XML data returned. The Dynamic UIM page executes these XPath-like expressions against the XML data obtained from the calls to server interface(s), and obtains data to use in UIM constructs (such as field values and conditions).
• The web server displays the formatted page of decision details.
