Healthcare providers aren’t allowed to tell law enforcement about a patient’s abortion if they received the procedure in a state where it is legal, it is protected by federal law, or it is permitted by state law, the Biden administration said Monday. The rule will take effect in 30 days, and it represents a meaningful shift.

But it’s unclear whether it will protect medical data for people who self-manage their abortions by receiving medication in the mail, often from a prescribing physician in a state with laws protecting reproductive rights.
