Regulation
When the new rule could take effect.
The rewrite is still a proposal. Its projected date has already moved once, and the proposed compliance period starts only when a final rule is published.
What it is
HHS's Office for Civil Rights (OCR), which enforces HIPAA, published the proposed rule on January 6, 2025, and comments closed on March 7, 2025. It would apply to covered entities (health plans, health care clearinghouses and health care providers that conduct certain transactions electronically) and to business associates, the vendors and service providers that create, receive, maintain or transmit electronic protected health information (ePHI) on their behalf. The federal regulatory calendar published in July 2026, the Unified Agenda, moved it to "long-term action" with final action projected for July 2027; the previous calendar, from September 2025, said May 2026. Those dates are HHS planning estimates and can move again. As proposed, a final rule would take effect 60 days after publication, and compliance would be due 180 days after that, 240 days after publication in total. Existing business associate agreements could get extra time. An agreement in place before a final rule is published, compliant with the current rule and not renewed or changed between the effective date and the compliance date could stay in use until the earlier of its next renewal or one year after the effective date. The extra time would cover updating the contract terms only. The safeguards themselves would still be due on the general compliance date. If a final rule were published in mid-July 2027, the general compliance date would fall in March 2028. OCR Director Paula Stannard told TechTarget in 2026 that OCR has not decided which proposals, if any, will be finalized.
What's the risk
The final text may differ from the proposal. In February 2025, seven health care groups, among them CHIME, MGMA, the Association of American Medical Colleges and the Federation of American Hospitals, wrote to the President and the HHS Secretary that the proposal "should be rescinded immediately," and called HHS's own cost estimate of about $9 billion in the first year "a woefully inadequate estimate." The American Hospital Association asked HHS to withdraw it in February 2026 and called the 72 hour recovery requirement arbitrary. Waiting for the final text carries its own risk, because the current Security Rule stays in force and OCR is enforcing it now (part two). The attacks the proposal is written for keep growing: in the 12 months to September 2026, hacking and IT incidents were behind 84 percent of the large breaches reported to HHS and 98.5 percent of the people affected, and January to September 2026 has the highest hacking share on record, 85.7 percent (our analysis of the HHS breach portal). These figures use the fields every report has. OCR writes its description of a breach only when it closes the case, so about two thirds of 2026 reports have none yet, and the attack method behind most recent hacking reports is not public. HHS's own preamble says that regulated entities "should already have" encrypted ePHI "in most circumstances" under the current rule. The practical risk is spending the next year on proposal-only details while the current-rule basics, the ones OCR investigates after a breach, stay unfinished.
What's the impact
- Treat July 2027 as a planning date. The calendar date has moved once already. Plan the work so it holds up if the date moves again, and adjust when a final rule is published.
- Fund the current rule's requirements first. A complete risk analysis, a working risk management plan and contingency plans for backup and recovery are required today, so that spending is sound whatever the final rule says.
- Expect customer contracts to move before the rule does. Nothing stops a buyer from writing the proposal's vendor terms into a contract today. Part five covers what those terms look like.
- Show the board what is required now and what is only proposed. Keeping the two lists apart helps the board fund current duties without committing to details that may change.
Questions to ask your team
- Which of our current security projects would we need anyway under today's Security Rule, and which depend on the proposal?
- When was our HIPAA risk analysis last updated, and does it cover every system that stores, processes or touches ePHI?
- Who is tracking the rulemaking, and what will we change in our plan when a final rule is published?
