Yeah, the original determination was a denial. I'm not a big believer in DRO reviews, so my experience with them is limited. The denial letter was useless as far as trying to figure out reasons and bases, it just made declarative statements without explaining any reasoning behind them.
Well, if no determination has been made i guess they can't make a statement on anything. If the NOD specifically requested a DRO review, that sounds about right.
When I submitted my NOD and requested in-person DRO review, all I got was the monthly "we're still working on your claim... lots of other claims.. blah blah..." type of letter from the VARO.
Just to clarify the above, I am not insinuating that an unscrupulous doctor might write you a letter in support of a claim. A dishonest doctor would do a veteran a disservice by doing so. When any doctor backs you up with a statement, he/she is placing their reputation on the line in support of a veteran and that professional should be commended for doing so.
I don't see a IME, an IMO or the required nexus letter, it will be required. A really good DBQ might suffice if the writer can make a connection to your already scd conditions but they will not just take it for granted. Go ahead and file the intent to file a FDC claim for the new conditions, that will mark your EED. Then get the IME/IMO, hopefully both together and then file the FDC.
