Wheelchair coverage/benefits

Hi,

If there’s already a thread for this, please move my post to the right one. I couldn't find it.

So, I'm looking for some insight into how things work when getting medical equipment through Medicare. Specifically, I'm looking at mobility aids—wheelchairs, basically. I see electric ones listed too, so I'm wondering if anyone knows how often those actually get approved and what the wait time is for the board to make a decision. Also, do you have to wait for the green light first, or can you buy the gear upfront and then file for reimbursement once Medicare decides the need is legitimate?
My questions apply to all types of medical aids.
From what I’ve read, recent changes to the rules have made it a bit easier to get certain things, like inhalers or commode chairs.

I’m asking because of a neuromuscular condition. I'd love to hear from anyone dealing with MS; I know there are people here with that. I'm stuck deciding between a standard electric chair or a specialized one that can tilt all the way back into a flat, horizontal position.

Best,

From what I understand, Medicare approves wheelchairs based on a specialist's recommendation, but the models they greenlight rarely actually fit the patient's specific needs, so people end up paying out of pocket just to get a decent one.
I have a feeling someone here will chime in soon with some firsthand experience, especially since I've seen plenty of threads discussing similar headaches.

Thanks for getting back to me. It looks like the discussion on Multipla is picking up steam, so maybe someone from their team will chime in soon. His biggest hurdle right now is pinning down the actual indications for use; that regulatory manual they use basically limits everything to dental supplies. I’m planning to dive deep into this over the next few days and will post updates here as I find them.
