What Is X-Mods and More?

X-Mods and More enables a timely and seamless exchange of data by using standard internet protocols, providing 24/7 access with no human interaction and limiting the risk of errors. Participating users connect with X-Mods and More by sending a WCIRB-assigned bureau number (BN) or a policyholder’s Federal Employer Identification Number (FEIN), and, if a single match is found, X-Mods and More returns the requested information.

The primary uses include:

  • Machine-to-machine access: Users can automate a scheduled connection that sends web service requests for all of their policies in need of updated data. Application programming interface access makes possible the automated retrieval of the following:
    • X-Mods, thereby removing a key obstacle of automated renewals
    • Key classification data, including the WCIRB-assigned classes and the classification that developed the most payroll in the most recent experience period
    • Policyholder name and address data previously reported to the WCIRB 
  • Replaces person-to-machine access: Rather than logging onto WCIRB Connect® to manually search for this information, users can develop their own user interface to request this information using the WCIRB BN or the policyholder’s FEIN, and the information for the selected risk is returned in seconds.

What Are the Benefits?

  • Provides data in real time, 24/7
  • Decreases the cost and effort to access and load data
  • Allows seamless integration of requested data into requester’s system
  • Uses only the data you need if you only need the X-Mod, capture only the X-Mod
  • Improves data accuracy and completeness in underwriting and reports
  • Is available at no additional charge

What Data Is Available?

X-Mods and More is built in conformance with WCUNDERWRITING an emerging national standard developed by the Workers Compensation Insurance Organizations. X-Mods and More returns the following:

  • 10 years of X-Mods by experience rating effective year (YYYY)
    • Insurer of record only receives the full experience rating effective date (MM/DD/YYYY)
  • Current reported policyholder names and FEINs 
  • Current reported policyholder addresses 
  • Count of in-force policies for the risk 
  • Standard classifications for the risk that are:
    • Assigned by the WCIRB along with date of assignment
