EVSpc Version 5010

This version is valid on January 1, 2012.

Important Information

Once you download the new 5010 software, it will override your current 4010 software. This means that you will not be able to send any 4010 transactions to MassHealth. If you plan to download the software before January 1, 2012, MassHealth recommends that you do one of the following:

  • download the new software on a separate computer to ensure that your 4010 data is not erased; or
  • download the new software only when you are ready to submit 5010 inquiries to MassHealth.

Please reference the EVSpc user guide, installation instructions, and the release notes for further instructions.

TPL Billing Resources and Information

In the 5010 environment, certain authorized provider types may use a new data element, “total noncovered amount,” to report noncovered charges for specific third-party-liability (TPL) exception conditions. Providers who are authorized to use a “total noncovered amount” when reporting specific TPL exception conditions are listed below. The exception instructions are located in the supplemental instructions in the applicable appendix of the provider manual, as indicated below.

The above provider manual appendices contain specific MassHealth billing instructions for members who have Medicare or commercial insurance. The TPL appendices supplement the instructions contained in the HIPAA Implementation Guides, MassHealth companion guides and billing guides.

Providers who are not authorized to use  the new 5010 field, “total noncovered amount,” should report the HIPAA adjustment reason code provided by the other insurer on their MassHealth claim submission to indicate that the other insurer has not paid the claim.
