  • Publication number: 20230010687
    Abstract: A claim adjudication system including an automatic adjudication pipeline that uses pipeline rules to automatically adjudicate a claim associated with a benefit plan at one or more stages. The automatic adjudication pipeline can redirect the claim to a user interface for manual review when a pipeline rule associated with a manual review condition is triggered. The user interface can present information about the claim relevant to the manual review condition in an integrated format, including highlighting the reasons for the manual review. A user can evaluate the claim in the user interface and provide user input that addresses the manual review condition, and the claim can be routed back to the automatic adjudication pipeline. The user input can also be used as training data for machine learning to adjust pipeline rules that are used to automatically process claims and to redirect future claims for manual review.

  • Patent number: 11079954
    Abstract: A deduplication memory system includes a virtual memory space, a physical memory space and a memory manager. The memory manager generates a user data entry that is stored in the physical memory space. The user data entry represents a unique user data of a predetermined granularity appearing in the virtual memory space, and includes first and second portions. The first portion includes information relating to a number of duplication times the unique user data corresponding to the user data entry is duplicated in the virtual memory space, and the second portion includes a selected part of the unique user data from which the unique user data may be reconstructed. The first portion may include an index to an extended reference counter table or a special data pattern table if the number of duplication times of the unique user data is greater than or equal to a predetermined number.
