Idaho actually already launched their 2025 Open Enrollment Period on October 15th, and it only runs through December 16th.*
...*Idaho has continued to doing this even though Nov. 1st has almost always been the official start date and the Biden Admin extended the end date out to Jan. 15th several years ago. The Centers for Medicare & Medicaid Services (CMS) issued new rules last year which I had thought were supposed to crack down on this & bring Idaho in line with other states, but apparently the Gem State was grandfathered in.
