    • Fiscal Intermediary Shared System Attending and Rendering

    Metadata Updated: December 13, 2025

    The Fiscal Intermediary Shared System (FISS) Attending and Rendering dataset provides a list of those attending and rendering physicians for the FISS. FISS edits require that the Line Item Rendering Physician information be transmitted when providers submit a combined claim. Claims that include both facility and professional components, need to report the rendering physician or other practitioner at the line level if it differs from the rendering physician/practitioner reported at the claim level.

    Note: This full dataset contains more records than most spreadsheet programs can handle, which will result in an incomplete load of data. Use of a database or statistical software is required.
