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 A key benefit of using EHNs is 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 or recertify, click here.
