Health Information Technology   Electronic Health Networks  


An electronic health network (EHN) or medical care electronic claims clearinghouses (also referred to as a clearinghouse or network) exchanges electronic health care transactions between payors and providers. EHN services include verifying the accuracy of claims submitted, reporting on errors identified during the data cleaning process, and formatting transactions to align with national standards established under the Health Insurance Portability and Accountability Act of 1996 (HIPAA).1 Two key benefits of using EHNs are increased efficiency in operations and reduced administrative costs.2

EHN Certification and Recertification

COMAR 10.25.07, Certification of Electronic Health Networks and Medical Care Electronic Claims Clearinghouses, requires government and private payors that accept electronic health care transactions originating in Maryland to accept transactions only from MHCC certified EHNs. To receive MHCC certification or recertification, a network must be accredited or certified by a nationally recognized organization where standards related to privacy and confidentiality, business practices, physical and human resources, technical performance, and security are evaluated.3   For information on how to certify, recertify, and a list of certified EHNs, click here.

During the 2023 legislative session, the Maryland General Assembly passed Chapter 249 (House Bill 812), Health  Reproductive Health Services Protected Information and Insurance Requirements (law).  The law prohibits the disclosure of legally protected health information by health information exchanges (HIEs) and EHNs operating in the State.  Legally protected health information includes mifepristone data, the diagnosis, procedure, medication, and related codes for abortion care, and other sensitive health services as determined by the Secretary of Health. 

The MHCC prepared guidance documents based on discussions with HIEs and EHNs during Town Halls convened in December 2023.  A listing of HIE Town Hall Participants is available here.  A listing EHN Town Hall participants is available here.  The following guidance is intended to support HIEs and EHNs with implementation of the regulations.

Implementation Guidance:  Health Information Exchanges (March 2024)

Implementation Guidance:  Electronic Health Networks (April 2024)  


Chapters 790 (House Bill 1022) and Chapter 791 (Senate Bill 748) of the 2021 Laws of Maryland, Public Health - State Designated Exchange - Clinical Information, require EHNs operating in Maryland to provide electronic health care transactions to the State-Designated health information exchange (CRISP) for public health and clinical purposes, including a State health improvement program, mitigation of public health emergency, and improvement of patient safety.4  The MHCC is required to report to the Governor and General Assembly by January 1, 2022 on the availability of funding and the sustainability of the technical infrastructure required to implement the provisions in the law.

The MHCC convened an EHN Workgroup consisting of representatives from CRISP and EHNs that transmit majority of transactions in the State to inform an iterative implementation strategy for the exchange of data required by the law.  Through workgroup deliberations, MHCC aims to establish a draft framework for data sharing that addresses data privacy and security.
