Yes, you can switch from Medicare Advantage back to Original Medicare during the Annual Enrollment Period (October 15 – December 7) or during the Medicare Advantage Open Enrollment Period (January 1 – March 31). However, if you want to add a Medigap supplement policy when switching back to Original Medicare, be aware that insurers in South Dakota can use medical underwriting outside your initial open enrollment period, potentially denying coverage or charging higher premiums based on health conditions. Plan your transition carefully.
Prior authorization means your Medicare Advantage plan must approve certain services (hospitalizations, surgeries, specialty referrals, durable medical equipment) before you receive them. This is required by many South Dakota Medicare Advantage plans and can cause delays in care. In 2024, CMS implemented new rules requiring MA plans to respond to prior authorization requests within 72 hours for urgent cases and 7 calendar days for standard requests. If denied, you have appeal rights. If prior authorization requirements concern you, consider whether Original Medicare with Medigap, which has no prior authorization requirements, may better suit your healthcare needs.
