(1) Where the veteran returns to active duty status, the award will be discontinued effective the day preceding reentrance into active duty status. If the exact date is not known, payments will be discontinued effective date of last payment and as of the correct date when the date of reentrance has been ascertained from the service department.

(2) Payments, if otherwise in order, will be resumed effective the day following release from active duty if claim for recommencement of payments is received within 1 year from the date of such release: otherwise payments will be resumed effective 1 year prior to the date of receipt of a new claim. Prior determinations of service connection will not be disturbed except as provided in § 3.105. Compensation will be authorized based on the degree of disability found to exist at the time the award is resumed. Disability will be evaluated on the basis of all facts, including records from the service department relating to the most recent period of active service. If a disability is incurred or aggravated in the second period of service, compensation for that disability cannot be paid unless a claim therefor is filed.
