CDiddy,
Welcome! Medical Processing takes precedence. See AR 600-8-24:
"1–24. Referral for physical disability evaluation
If a commissioned or warrant officer is being processed for REFRAD, separation, or retirement or has been referred for elimination action, when it is determined that the officer has a medical impairment that does not meet medical retention standards, the officer will be processed as set forth in paragraphs a, through d, below.
a. A commissioned or warrant officer under investigation for an offense chargeable under the Uniform Code of Military Justice (UCMJ) that could result in dismissal or punitive discharge may not be referred for or continue
disability processing unless—
(1) The investigation ends without charges.
(2) The commander exercising proper court-martial jurisdiction dismisses the charges.
(3) The commander exercising proper court-martial jurisdiction refers the charge for trial to a court-martial that
cannot adjudge such a sentence.
b. When a commissioned or warrant officer, as applicable, is being processed for one of the actions listed in (1) through (5), below, the officer will be processed in accordance with the provisions of this regulation and through the MEB/PEB system. If the result of the physical disability evaluation is a finding of physical fitness, the Army Physical Disability Agency will approve the findings for the Secretary of the Army and forward the proceedings to CDR,
HRC–Alexandria (AHRC–OPD–A), to be processed with the other action. If a physical disability evaluation results in a finding of physical unfitness, both actions will be forwarded by CG, HRC–Alexandria (AHRC–OPD–A), to the
Secretary of the Army or his designee for determination of appropriate disposition.
(1) Referral to the DAADB except when the DAADB is convened as a result of an imposed reduction in force.
(2) Involuntary REFRAD due to civil conviction or moral turpitude.
(3) Resignation for the good of the service.
(4) Referral for elimination under chapter 4.
(5) Request for separation, resignation, or retirement in lieu of elimination.
c. When a physical disability evaluation of an officer processed for separation or retirement for the reasons indicated above results in a finding of unfitness and a recommendation that the officer be placed on the Temporary Disability
Retirement List (TDRL), the Secretary of the Army or his designee may direct that the officer be placed on the TDRL with the provision that if the officer is later removed in due course from the TDRL for disability separation or
retirement, the officer is to be retired, but if the officer is later removed in due course from the TDRL because he is found fit, the officer is to be separated from the service, effective on the date of the officer’s removal from the TDRL with a specified characterization of discharge. As in the case of an officer processed for separation or retirement for the reasons indicated above whose physical disability evaluation results in a finding of unfitness and a recommendation that the officer be separated or permanently retired, the Secretary of the Army or his designee may direct that either the separation or retirement action under this regulation or the disability action take precedence.
d. When an officer is processed for separation or retirement for reasons other than those indicated above, physical disability takes precedence if the officer is retained with consent. The procedures in paragraph 1–22 will be followed.
e. Officers previously determined physically unfit and continued on active duty under AR 635–40 must be referred for disability evaluations at final retirement or separation
