Electronic Data Interchange Overview

The following HIPAA information is for Wisconsin Medicaid providers and Wisconsin Health Care Trading Partners.

The Administrative Simplification provisions of the Health Insurance Portability and Accountability Act of 1996 (HIPAA), commonly referred to as the "HIPAA standards," require the Secretary of the federal Department of Health and Human Services (HHS) to adopt national standards for:

  • The electronic transmission of administrative and financial health care information (e.g., claims) and code sets (e.g., diagnosis codes, procedure codes, procedure code modifiers).
  • Unique health care identification numbers for providers, health plans, employers, and individuals.
  • Privacy and security of individually identifiable health care information.
  • Electronic submission of claims attachments.
  • Enforcement of the components of HIPAA.

Although federal HIPAA legislation is targeted at standardizing electronic health care transactions, HIPAA will also affect many aspects of paper billing, such as coding structures and required data elements. Wisconsin Health Care Trading Partners and providers participating in health care programs administered by the Wisconsin Department of Health and Family Services (DHFS), Division of Health Care Financing, such as Wisconsin Medicaid, BadgerCare, SeniorCare, Wisconsin Chronic Disease Program (WCDP), Wisconsin Well Woman Program (WWWP) should check back to this site for additional materials as they become available. 

Trading Partners

The DHCF defines a trading partner as a covered entity that exchanges electronic health care transactions as mandated by HIPAA. (Refer to Section III of the Trading Partner Profile for a listing of electronic health care transactions.) Therefore, the DHCF considers the following covered entities to be its trading partners:

  • Billing providers who exchange electronic transactions directly with the DHCF.
  • Billing services and clearinghouses that exchange electronic transactions directly with the DHCF on behalf of a billing provider.
