Reporting Electronic Health Care Transactions

Background

Maryland law (Chapter 791 and Chapter 790, Public Health – State Designated Exchange – Clinical Information, 2021) requires electronic health networks (EHNs) to provide electronic health care transactions to the State-Designated Health Information Exchange (CRISP) for certain purposes. More recently, legislation passed in 2025 (Chapter 615) clarifies that transaction information may also be used to support Maryland’s participation in the AHEAD Model, administered by the Centers for Medicare & Medicaid Services.

The law requires CRISP to develop policies and procedures to support implementation, consistent with regulations adopted by the Maryland Health Care Commission (MHCC). Final regulations, COMAR 10.25.07, Certification of Electronic Health Networks and Medical Care Electronic Claims Clearinghouses became effective on November 10, 2025.

Technical Submission Guidance

CRISP convened stakeholders, including EHNs to inform the development of Electronic Health Care Transactions Technical Submission Guidance to support implementation of the law. The technical submission guidance details requirements for submitting electronic health care transaction information to CRISP.

CRISP is currently requesting comments on the draft submission guidance, available in the documents or using the link below. Comments may be submitted to MDCommunications@crisphealth.org by January 19^th, 2026, at 5:00 pm EST. CRISP anticipates finalizing the technical guidance in early 2026.
