I apologize for the concern with your activities. To earn rewards for your annual wellness exam, your doctor will have to bill it as an annual wellness exam. If it is billed as an office visit or other exam, it will not qualify.
Yes, you need to make a specific appointment for the wellness visit. Humana Medicare Advantage plans also will pay for an annual physical, at least mine does. You can also get that at the same time.
But the wellness visit needs to be at least a year from your last one or your Welcome to Medicare visit.
