On August 10, Governor Maura Healey signed H.5595, and Massachusetts stopped being a state that lists the reasons an abortion may be performed after 24 weeks. The law takes effect 90 days after signing, which lands in the first half of November, five days after voters go to the polls on November 3.
Almost nobody is talking about the timing. It is the most consequential change to Massachusetts reproductive law since the ROE Act, and it arrives in the same week as a statewide election.
What the old law required
Before H.5595, Massachusetts allowed an abortion at or after 24 weeks only in defined circumstances. The statute set out a four-part framework, and a physician had to fit the patient into one of its categories. In practice that meant a documented threat to the patient’s life or physical health, a severe fetal anomaly, or a mental health emergency, with the categories doing the deciding.
There was a second requirement layered on top. A post-24-week abortion had to be performed in a hospital.
Both of those are gone.
What replaces it
The new standard is the professional judgment of the physician. The four-part framework is eliminated, not expanded, and the decision moves from a list of qualifying conditions to the doctor treating the patient. The hospital-setting requirement for post-24-week procedures is also removed.
That is a structural change, not a numerical one. The old law asked whether a patient’s situation matched a category the Legislature had written down in advance. The new law asks what the physician concludes. Those questions produce different answers in the cases that are hard, which are the only cases where the statute ever mattered.
Why the effective date matters more than usual
Ninety days from August 10 puts the effective date in early to mid November. The state election is November 3. So the law will still be pending on Election Day and operative shortly after it.
That sequence has a practical consequence for anyone reading coverage this fall. Between now and the election, the law is real, signed, and not yet in force. A physician deciding a post-24-week case in October is still working under the four-part framework. The same case in late November is decided under the physician-judgment standard. Reporting that treats the two periods as interchangeable will get it wrong.
What this does not change
Two clarifications, because the coverage of this bill has been unusually loose.
First, this is a change to the standard governing post-24-week care, not the creation of a new right to abortion at any point in pregnancy for any reason. Massachusetts already permitted abortion before 24 weeks without cause. What changed is who decides after 24 weeks, and on what basis.
Second, the shift to physician judgment does not remove the physician. The statute continues to route the decision through a licensed doctor exercising professional judgment, which remains a standard that can be reviewed, and which carries the ordinary consequences of practicing outside it.
Where the litigation is likely to come from
A standard built on professional judgment is harder to challenge on its face than a list of categories, because there is less text to attack. It is also harder to apply consistently, which is where disputes tend to start.
The removal of the hospital requirement is the provision most likely to generate near-term practical fights, because it touches licensing, facility standards, and what individual institutions choose to permit on their own premises. Nothing in a state statute obliges a private hospital or clinic to offer a procedure it has decided not to offer.
The physician-judgment standard is the provision most likely to generate long-term ones. Every standard of that kind eventually gets tested by a case at its edge.
What to actually watch
Confirm the operative date before relying on it. Ninety days from an August 10 signature is arithmetic, but effective dates in Massachusetts can turn on how the act itself is worded, and the working figure circulating in coverage is approximately November 8. Anyone making a clinical or legal decision in that window should check the session law rather than a news summary, including this one.
After that, watch two things. Whether the Department of Public Health issues guidance interpreting professional judgment, which would tell providers a great deal about their exposure. And whether any hospital system publicly declines to expand what it offers, which would show how much of the old framework survives as institutional policy after being removed from the statute.
The Legislature changed the rule. It did not change who owns the buildings.
