I have an appointment in Milw. audiology. For impacted wax removal, I must cancel, because of lack of transportation, may I go to a ENT Doctor and have the bill sent to the VA ?

No

You have to be assigned to the Choice Program first or the Dr's bill will be comming out of your pocket.

There is transportation

You go to your primary care doctor, or contact him, her,to go outside of V.A. you must be approve for veterans choice programs and va has transportation for all veterans!

You would have to contact your primary care physician first.

I suspect not, and there is transport services for veterans
