Changing status on a non-embedded HSA plan in the middle of the plan year

[Guest AHayhow]

We have a member on a non-embedded HSA plan and has family coverage. The spouse has met the entire $4000 deductible. The spouse is coming off the plan to go onto his employers plan. The employee will have a change in status and will move to a single plan with a $2000 deductible. Would this employee need to still satisfy her $2000 deductible since it was the spouse that met the entire family deductible and he will no longer be on the policy?
