First, congratulations on the receipt of military disability retirement orders with a DoD PDRL disposition! To assist with a smooth transition in the processing of your DoVA entitlements upon becoming a military disabled veteran, ensure that your DD Form 214 is uploaded now to the DoVA D-RAS in one of two ways: via eBenefits by yourself and/or via submission by your MSC.
Second, at this particular point in time since you are still on military active duty, I would highly suggest that you immediately contact your assigned MSC when accepted into the DoD IDES process to review your previous selections on the completed VA Form 21-0819 submitted to the DoVA D-RAS by the MSC. As such, you were given an opportunity to chose via the statement "No I do not want VA compensation in lieu of military retired pay" by either checking or not checking the corresponding box in item 13.
In retrospect, upon completing VA Form 21-0819 "VA/DOD JOINT DISABILITY EVALUATION BOARD CLAIM" under Section IV "MILITARY RETIRED PAY" which states "IMPORTANT - Unless you check the box in Item 13 below, you are telling us that you are choosing to receive VA compensation instead of military retired pay, if it is determined you are entitled to both benefits. If you are awarded military retired pay prior to compensation, we will reduce your retired pay by the amount of any compensation that you are awarded. VA will notify the Military Retired Pay Center of all benefit changes. If you receive both military retired pay and VA compensation, some of the amount you get may be recouped by VA, or in the case of Voluntary Separation Incentive (VSI), by the Department of Defense." you are given an opportunity to accept or decline VA compensation in lieu of military retired pay if it's determined to be applicable to your specific military pay situation. Take care and enjoy!
Thus, I quite often comment that "possessing well-informed knowledge is truly a powerful equalizer!"
Best Wishes!
