Someone wrongly removed must be put back at once
What the document says“the State shall immediately re-enroll such individual under the State plan (or waiver of such plan), retroactive to the date of such disenrollment.”
The section requires the State, where it finds someone was wrongly identified as dead and removed on that basis, to re-enroll that person at once, backdated to the day of removal. Nothing in the subsection stops a State using other electronic data sources to spot potentially deceased people, so long as it also meets these requirements and the rest of the eligibility rules.
What the document actually says“the State shall immediately re-enroll such individual under the State plan (or waiver of such plan), retroactive to the date of such disenrollment.”
The state must put the person back on the rolls. It must do so at once. Cover runs back to the day they were taken off.
So no gap is left in the person's cover. The state may still use other data sources. It must meet these rules as well.
No action is recorded against this proposal. That is not evidence that none has been taken, and nobody has yet read it against the record. See what the tracker does not yet cover.
