3M™ Core Grouping Software for Microsoft® Windows®-based systems

  • Provides fast, accurate Medicare and non-Medicare grouping of claims
  • Delivers appropriate inpatient, outpatient, and professional edits to help reduce compliance risk
  • Calculates reimbursement for valid claims
  • Generates ready-to-bill claims and helps reduce reprocessing

  • Many patient types and payers

    Providers, insurance companies, managed care companies, claims review companies, state and federal agencies—they all need to generate clean, compliant and accurate claims for a broad variety of patient types.

    Industry-wide payment reform means the number of state and commercial payment programs continues to grow. Each patient type and payer brings a unique set of grouping and compliance rules and reimbursement rates. These rules and rates can change often to reflect a continual need to control health care costs.

    When you tally all the different patient types and payers, it’s nearly impossible to get the claims processing tools you need to address them all and always stay on top of the latest changes.

  • A single tool to meet all your processing needs

    3M Core Grouping Software is a computerized application that sets a new standard for efficiently and effectively processing claims data. With 3M’s proven grouping, editing and reimbursement calculation at its core, the software classifies patients, evaluates the accuracy and completeness of the clinical data, identifies potential errors and calculates the expected reimbursement. The software includes a number of continually-updated grouping methodologies, editing components and reimbursement formulas delivered in a single, comprehensive tool that can help you:

    • Evaluate the accuracy and completeness of clinical data
    • Review coding accuracy
    • Monitor and control costs
    • Understand your expected reimbursement
    • Manage claims denials
    • Estimate profitability
    • Project expected reimbursement for budgetary and management purposes

Features and benefits

  • Output and processing options

    The 3M Core Grouping Software is written as a transaction processor, with no database storage or reporting facility. Output includes a series of individual:

    • Patient-level reports that can be directed to a printer individually or from an appended file
    • Output files in a fixed length or delimited text file that can then be uploaded to another system for reporting and analysis
  • Ability to customize

    By customizing the 3M Core Grouping Software, you can also:

    • Use code-mapping that allows ICD-9 or ICD-10 codes from one year to be used with a grouper from another year
    • Evaluate all secondary diagnoses as principal, generating a potential DRG for each secondary diagnosis
    • Identify which grouper, statistics and reimbursement formula should be used for each patient type, so data does not need to be sorted before processing
    • Select the birth weight sources (either through direct data entry or coding)
    • Customize grouper-effective dates
    • Select only non-regulatory edits that you want to see
  • Interactive or batch

    The 3M Core Grouping Software supports a traditional batch process—input of a fixed length, delimited, or 837i file and output of a fixed length or delimited file—or an interactive interface mode.


    Batch processing handles volumes of records efficiently, while interactive interface mode lets you enter, modify and process individual claims and review the output from the grouping and reimbursement calculation.


    The software is adaptable and scalable and can operate standalone or networked (file server and client workstation) on a Microsoft Windows-based PC. Refer to the 3M Core Grouping Software Configuration Sheet for specific information on hardware and software requirements.
