Can the VA refuse to treat a 100% service-connected veteran citing their case as "too complex," and also refuse to outsource them for care?

I would recommend that you consult with a VSO (veteran service officer) if you haven’t already done so. These officers can be found through your local VA office, local VFW, American Legion, AmVets and DAV. These organizations are usually very good about trying to get the resources you need.
If none of these organizations are helpful, you can always direct your situation to the Va IG office.
I have had the same luck as you had concerning a Senator. However, this is an election year and It might ignite a flame under the ass of your congressman and Senator.
Since you are rated at 100% you should not be turned away for any illness or conditions that you may have. Service connected or not.
The Choice Program, Mission Act, Community Care or whatever that program is called now were designed for Veterans to get local care, especially if your VA doesn’t have the facilities to treat you. You could also be sent to a VA facility that might have the proper medical personnel and equipment to diagnose and treat you. At no expense to you. This also applies to all Veterans that are registered with the VA regardless of disability rating.
I’m sorry that I couldn’t provide you with much advice but I hope that this helps you.
God bless and good luck

Someone needs to listen to her. I don't have any answers. I wish you well.

It troubles me deeply that Veterans must FIGHT for fair treatment, butt, if you WANT a sex change ... JUST ASK !

I can't comment on your case because everyone's case is unique to each individual. What I can do is to advise you to write the Office/Department of Veterans Affairs office in Washington D.C..

Have you spoken with the onsite VA advocate's office? The DAV may also be able to help. The DAV does not require membership to assist you.

In the case of your payment for meds prescribed by an outside doctor, have the doctor route the prescription through your Personal Care Phisician and then he can send it to the Pharmacy in the VA to be filled. Then you get your meds and all you pay is the co-pay which used to be $8 per month. Do you have a Care in the Community office at your local VA. If you do contact them and see if they can help you.

I had a back problem and the VA sent me from Rapid City, SD to Omaha, NE to the VA hospital there for a Laminectomy on my L4 vertebra about 8 years ago. I still had problems with pain that they could only address with pills. After a while they decided they couldn't do anything more, so they turned me over to Monument Health the local medical affiliate here that is now owned by Mayo Clinic. I went thru their pain management program and finally ended up with an Orthopedic Surgeon in September of last year, he looked at my CT scan (I can't do an MRI anymore because of a spinal cord stimulator that is surgically implanted) he said it made him want to sit in the corner and cry. He sent in the paperwork to the VA and he scheduled me for a laminectomy on the L2, L3, and the L4, vertebras. Evidently they didn't get enough of the L4 when they were in there the first time. This did wonders for my back pain but didn't get it all. I have developed a condition known as Arachnoiditis. That is not a fear of spiders, the Arachnoid is the sheath around nerve fibers and also the spinal column. Arachnoiditis is when the nerve fibers in the sheath get fused together with scar tissue. They when you move these fibers can no longer slip and slide over one another they pull and stretch. There is no cure for it and it can't get better, it can only get worse, and it is. Through a healthy dose of drugs and the stimulator I can usual mask the pain, today isn't one of those days. The most prevalent cause of Arachnoiditis is an errant stick with a cortisone shot that penetrates the arachnoid sheath, I think that accounts for about 95% of the cases. I have had so much cortisone and other crap shot into my back I slosh when I walk. First there was the Pro Low treatments where the injected a saline solution into the ligaments in the back to make them inflamed and grow stronger. Which did no good. Then came the cortisone shots. Those never ever gave me even a moments relief, but every time I saw my PC he would ask how was my back I would say it was a mess and off I would go for more cortisone shots. Finally refused more shots and the Ortho guy at the VA said I don't blame you. So back I went to my PC and he sent me outside to a Sports Medicine Group who wanted to give me more cortisone shots. I said no way then they sent me off for some hot wire treatments where a needle is inserted under x-ray into the nerve and then a wire is run thru the needle which is heated with radio waves and it burns the nerve and kills it. I went thru that for a while and it didn't work so they implanted the spinal cord stimulator. Vola, success, pain was mask for a while. As time went on I had to turn the stimulator up higher and higher to get the same amount of relief. I used to run it on 2% to 3% at night and 4% to 5% during the day now I run it at 20% to 25% night and day. Anyway that is my tale of woe, I think the VA caused my arachnoiditis but they won't admit it, they said it is scar tissue from the first laminectomy. How the hell that scar tissue grew about 4 inches and then got inside the Arachnoid Sheath beats the hell out of me. The same old VA that let me walk around on a broken leg for 4 months two years ago, but that's a story for another day,

Something is really wrong here…….my suggestion is to consult an attorney who specializes in VA issues. Being 100% I don’t see how they can deny you the care you deserve either thru the VA or via Tri West Community Care.

Apparently by what your saying they can and are doing what you quote

CAN They?
Uh.... "NO"!

Contact Your Congressmen, State Senators & The US President.
The VA May TELL You That, But It's Pure Bull Shit.
I'm Going After The VA Also....
