On March 22, 2024, Senator Mark Warner introduced the Health Care Cybersecurity Improvement Act of 2024. It proposed making certain advance or accelerated Medicare payments after a cyber incident available to providers that meet minimum cybersecurity standards set by the Department of Health and Human Services (HHS). This was a proposed payment-linked condition—not a universal cybersecurity mandate for the healthcare sector.

What Warner’s March 2024 bill proposed

The bill focused on financial support after a cyber incident. Under the proposal, an affected healthcare provider could qualify for advance or accelerated Medicare payments if it met minimum cybersecurity standards established by the HHS secretary. If the provider’s intermediary had been targeted, the intermediary would also have to meet minimum standards for the provider to qualify. The bill’s provisions were set to take effect two years after enactment.

Warner’s office presented the measure as a response to the ransomware attack on Change Healthcare, which disrupted billing services and placed financial pressure on providers. The proposal paired a potential source of post-incident cash flow with a baseline-security condition. It did not, as described in the March announcement, impose the same requirements on every healthcare organization regardless of whether it sought the specified Medicare payments.

How the September 2024 proposal differed

A separate bill introduced later that year proposed a broader regulatory approach. The Health Infrastructure Security and Accountability Act, introduced by Senators Ron Wyden and Mark Warner on September 26, 2024, would direct HHS to develop and enforce minimum cybersecurity standards across a wider range of healthcare organizations.

Feature Health Care Cybersecurity Improvement Act of 2024 Health Infrastructure Security and Accountability Act
Introduced March 22, 2024, by Senator Mark Warner September 26, 2024, by Senators Ron Wyden and Mark Warner
Main mechanism Eligibility for certain advance or accelerated Medicare payments after a cyber incident, subject to minimum standards HHS-developed and enforced minimum cybersecurity standards
Organizations described Affected providers and, when applicable, the targeted intermediary Providers, health plans, clearinghouses, and business associates
Additional provisions described Two-year delay after enactment before provisions take effect Stronger standards for systemically important entities and those important to national security; changes to HIPAA fines and hospital cybersecurity funding, including attention to low-resource rural and urban hospitals

The September proposal’s additional provisions and scope are summarized in the Senate Finance Committee’s September 26, 2024 announcement. It should not be conflated with Warner’s March bill: one tied specified Medicare-payment eligibility to standards, while the other proposed a broader HHS standards-and-enforcement framework.

Why multifactor authentication entered the debate

Warner cited the Change Healthcare incident as an example of how a basic security weakness can matter. In a July 12, 2024 statement, he pointed to the lack of multifactor authentication (MFA) and wrote: “Due to some entities failing to implement basic cybersecurity best practices, such as the lack of multi-factor authentication resulting in the successful attack on Change Healthcare, the capability required of a threat actor to carry out an operation in the sector can be quite low.”

That July statement provides context for Warner’s concerns; it is not language from the March bill. The cited bill summary does not establish that the March proposal specifically required MFA. Warner’s July 12, 2024 statement

Other congressional and HHS activity

Warner’s bills were part of a wider policy discussion, but other activity should be kept distinct from their provisions.

  • House hearing: The House Energy and Commerce Committee held “Examining Health Sector Cybersecurity in the Wake of the Change Healthcare Attack” on April 16, 2024. Its repository includes witness materials and the hearing record, with materials updated through June 25, 2024. House Energy and Commerce Committee hearing materials
  • Proposed HIPAA Security Rule changes: In December 2024, HHS published a fact sheet describing separate proposed changes that included ongoing technology-asset inventories and network maps, reviewed at least every 12 months and after relevant changes to an entity’s environment or operations. These were agency rulemaking proposals, not provisions of either Warner bill. HHS fact sheet on proposed HIPAA Security Rule changes

What is established about the bills’ status

The cited materials establish the bills’ introductions and described provisions, but do not establish their later legislative disposition. They should therefore be described as proposals; these sources alone do not show whether either became law or its current status. A present-day status claim requires confirmation in an authoritative, current legislative record.
