Medical Data Call

As indicated in Circular Letter 662, as of January 1, 2023 the Wisconsin Compensation Rating Bureau (“WCRB”) will collect Wisconsin medical data directly from its member insurers and will no longer utilize the National Council on Compensation Insurance, Inc. (“NCCI”) as its medical data collection vendor. All members insurers participating in the Wisconsin Medical Data Call are required to report their Wisconsin State medical data (i.e. transactions with jurisdiction state code 48) directly to WCRB instead of reporting it to NCCI.

The following documents contain reporting guidelines and other helpful information for reporting medical data information to WCRB. For questions regarding the WI Medical Data Call process, please email
