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?

Go to your local DAV, American Ljegion ,VFW and asked to speak to the centers VA claims Agent. He or she will want any records medical records service records even award letters don't forget to take your DD 214.
These claims agents will be working for you they will instruct you on how to fit in all the paperwork to put in a claim for your service related injuries do not go to your States claims agent stay away from State the only person that you are interested in is in local VFW, DAV, American Legion
Brother I was 90% for 9 1/2 years once a president Trump got in the office they put a ruling in that said all claims must be answered between 4 to 6 months if they are not answered you get the claim automatically if they denied a clean and you put in a a cream yourself and you win the claim on appeal the person who denied your claim is fired and I know that happened to me I'm 100% from disabled unfortunately mine is PTSD, I HOPE this can put you on the correct Path.
REMEMBER, The More Records you provide the better chance you have for success.

I used my Congressman in Calif. and got a response in 4 days.

Missed this until recent replies popped it up on my feed.
My recommendation, if your troubles have not already been resolved, would be to change your Primary to Baltimore VAMC or Loch Raven VAMC instead of beating your head against the same rock in DC over and over again.

Yes they can if it's too complex just keep fighting!!!

You have Veterans Choice now.... They can't refuse unless it's out of state!! Then you will have a copay... Find a local Doctor that agrees with the Diag and it's related to your disability....then it should be be covered... Good luck!!

As far as the medicines from community care providers, most of their offices don't read the consult they get with instructions on how to submit a prescription. The consult has a form for the doctor to fill out and fax to the VA pharmacy.

I have a very complicated case as well but only because I stay on top of my care, things are getting done. The community care office at our local hospital is quite frankly awful. Hang in there and stay on top of it. I would also recommend DAV.

My 2 cents as a Patient Advocate. Everything always leads to the Patient Advocates office. File a White House Hotline complaint, it will find its way to the PA office. Call the directors office, you’ll be referred to the PA office. File with your local Congressional rep, it’ll come to the PA. So call your local PA office. If they aren’t doing anything a sl to speak to the their Director. Request a FOIA on your case to see what if anything is being done and act accordingly if not. Best of luck.

Senator isn't the right answer, Congressional Representative is. Senators pass laws, Congress represents you. I had to get my Congress woman involved in my care, Shaheen D NH
Made appt, saw a 23 year old staffer she was the VA liaison and by the time I finished my long sad story SHE was in tears..... By the time I got home from that meeting I had a message on my home phone from the head of my VA hospital.....Long story short, I got the care I needed and they went out of their way to provide it

I learned there are SIGNIFICANT differences between VA hospitals in different regions. n 2008 I moved from Southern California, to the Puget Sound area. The difference in medical care in the Long Beach VA and and Seattle was literally POLAR OPPOSITES. In Long Beach, most of the clerical staff had VERY bad attitudes and the care was very poor. Seattle has been outstanding

I'm 70% disabled. Two years ago I was having major problems with my neck... which is NOT service connected (YET). After getting the results from an MRI and other diagnostic tests, it was determined that ALL of the discs in my neck were gon, and the vertebrae were bone-on-bone, and the vertebrae were starting to disintegrate. The Chief Neurologist at the Seattle VA said "You need surgery, NOW! If you get even the slightest case of whiplash, you will be quadriplegic... IF you survive." He went on to say "I do NOT have the skill set to do this surgery, nor does any VA doctor in this region"

He said that he was referring me to University of Washington Harborview Medical center, the ONLY Trauma Center in WA State.

When I asked about the UW Medical Center that was near my home, he said "I would NOT feel comfortable sending you to that hospital. You need a TOP Cervical Neurosurgeon. Harborview is the only hospital in the region that has doctors with the skills you need." My Primary care doctor agreed.

They pushed the referral through, and two months later I was undergoing a 12+ hour surgery to stabilize my neck (with $83,000 of titanium hardware). Ten days in the hospital, and a SECOND surgery one month later, the total costs were over $350,000. Paid by the VA (after a few 'bumps').

Sometimes you have to raise a fuss. I STRONGLY SUGGEST CONTACTING YOUR ELECTED REPRESENTATIVE, NOW!
