  • Patent number: 11610653
    Abstract: Systems and methods to improve the optical character recognition of records, and in particular health records, are provided. An image of a medical record is received, and an initial optical image recognition (OCR) on the image is performed to identify text information. The OCR signal quality may be measured, and areas of insufficient OCR signal quality may be isolated. The signal quality is determined by a weighted average of semantic analysis of the resulting text, and/or OCR accuracy measures. The OCR process may be repeated on the isolated regions of lower signal quality, each time using a different OCR transform, until all regions are completed with a desired degree of signal quality (accuracy). All the regions of the document may then be recompiled into a single document for outputting.

  • Patent number: 11581097
    Abstract: A medical information navigation engine (“MINE”) is capable of inferring referral activity not reported into a referral workflow system by utilizing intent-based clustering of medical information. The intent based clustering reconciles received medical data, from a variety of sources, and then clusters the data by applying one or more clustering rules. After the referrals not otherwise reported are inferred, they may be utilized to generate metrics that can be utilized to enhance patient care, and reduce costs. Metrics may be generated for both in-network and out-of-network referrals in order to distinguish differences in reporting activity.

  • Patent number: 11468981
    Abstract: Systems and methods for managing audit risks utilizing the true state of the patient are provided. A number of medical records for a patient are subjected to predictive modeling for various conditions (known as patient ‘true state’). The true state is then cross referenced by the eligible Medicare documentation, and any findings that are being submitted to MediCare for reimbursement. The result of this cross referencing is the ability to classify each finding and/or true state into a “green, “yellow”, or “red zone”. The green zone is where the finding, documentation and true state are in good alignment. A red zone is where the finding and the true state are entirely at odds. The yellow zone is where the findings and the true state are in agreement, but where there is still audit risk that may be resolved through one or more “opportunities”.

  • Patent number: 11424013
    Abstract: A sorter of medical findings for assessment by a medical coder is provided. In some embodiments, the sorter receives information about a user (coder), including identification, a role, and historical activity. The sorter determines whether to run in exploration or exploitation modes. Exploration is used to explore the scope of the findings and also identify variables that impact a finding. Exploitation is designed to maximize a goal (such as throughput or profitability). Lastly a finding is selected and provided to the user. The selection is based upon computing internal parameters when in exploration, or based upon optimizing for criteria when in exploitation. The sorter may also determine competency for the user, and cut them off from performing additional coding if they are found incompetent.

  • Patent number: 11403330
    Abstract: Systems and methods for generating customized annotations of a medical record are provided. The system receives a medical record and processes it using a predictive model to identify evidence of a finding. The system then determines whether to have a recall enhancement or validation of a specific finding. Recall enhancement is used to tune or develop the predictive model, while validation is used to rapidly validate the evidence. The source document is provided to the user and feedback is requested. When asking for validation, the system also highlights the evidence already identified and requests the user to indicate if the evidence is valid for a particular finding. If recall enhancement is utilized, the source document is provided and the user is asked to find evidence in the document for a particular finding. The user may then highlight the evidence that supports the finding. The user may also annotate the evidence using free form text.
