It is clear, though, that separation or retirement for medical disability under Title 10 USC, Sec. 1201 et seq., will not require repayment.
I agree that the RE code would be the triggering mechanism for a recoupment action. But if this were an erroneous action, it will resolve in the Servicemember's favor either at the
BCMR or in Federal Court of Claims. I think you could petition for a change of code, or go to court under Military Pay Act.
"(e) Repayment of unearned portion of bonuses and other benefits when conditions of payment not met.
(1) A member of the uniformed services who receives a bonus or similar benefit and whose receipt of the bonus or similar benefit is subject to the condition that the member continue to satisfy certain eligibility requirements shall repay to the United States an amount equal to the unearned portion of the bonus or similar benefit if the member fails to satisfy the requirements, except in certain circumstances authorized by the Secretary concerned.
(2) The Secretary concerned may establish, by regulations, procedures for determining the amount of the repayment required under this subsection and the circumstances under which an exception to the required repayment may be granted. The Secretary concerned may specify in the regulations the conditions under which an installment payment of a bonus or similar benefit to be paid to a member of the uniformed services will not be made if the member no longer satisfies the eligibility requirements for the bonus or similar benefit. For the military departments, this subsection shall be administered under regulations prescribed by the Secretary of Defense."
