HB 333 Maryland House of Delegates · 2025 Regular Session

Healthcare Ecosystem Stakeholder Cybersecurity Workgroup

HB 333 requires Maryland's healthcare ecosystem entities - including hospitals, medical facilities, data exchanges, and other defined providers - to adopt cybersecurity standards, implement a "zero-trust" security approach, undergo third-party audits, and report incidents to the State Security Operations Center. It mandates the Maryland Health Care Commission to hire a cybersecurity expert to advise on oversight and collaborate with security offices. The bill also directs the Department of Emergency Management to convene a workgroup to study and improve healthcare cybersecurity practices. These requirements directly affect healthcare providers and data handlers but exclude insurers and pharmacy benefits managers.

MINOR

The bill was finalized and enrolled for the Governor's signature, changing its status from a draft to an enacted law. The substantive policy content regarding cybersecurity workgroups and definitions remained consistent, though the text was reorganized to correct a previous error where Insurance and State Finance articles were listed in the wrong order.

Scope change

The bill's scope and applicability remain unchanged; it continues to establish the Healthcare Ecosystem Stakeholder Cybersecurity Workgroup and define related terms within the Health General Article.

TECHNICAL

The bill's status changed from 'Third Reading' to 'Enrolled,' indicating it has passed all legislative stages and is ready for the Governor's approval.

The order of the bill's sections was corrected to properly list repeals and additions to the Insurance and State Finance articles in the correct sequence.

Formatting and layout were adjusted to align with the final enrolled bill format, including the addition of proofreader signature lines.
