MDM44,
I believe you are speaking about a UHC Medicare Advantage plan and yes, they do cover post-mastectomy breast (external) prosthesis and bras, under the same conditons as traditional Medicare. It is actually legislated by the Women's Health and Cancer Care Act. These are covered by your Part B Medicare which you are getting through your UHC MA plan.
It sounds like you might be having a difficult time locating a fitter. This is a certified prosthetic professional. Medicare specifies that this is the type of professional that has to do the fitting. I would think that your doctor should know of one in the area. They can be called "Mastectomy Fitters " or Mastectomy prosthetic fitters.
The way I understand it, you take your prescription to a certified fitter and they fix you up and bill your insurance company. See if this is described in your plan booklet.
Now you may need to find out from your UHC MA plan if they have these fitters in a network. They are more specialized than your regular DME provider but they may have a certified fitter within their fold.

Medicare ( including your Advantage plan) covers the prosthetic and the bra at specific intervals - your plan should be able to tell you the intervals but it should also be in your plan booklet.
Good Luck -
