Each agency may at its own discretion, adopt an appeals process to handle situations where the finance officer or other designated officer disapproves a claim, or where the claimant is not satisfied with the amount approved on the claim. In the event a disapproved claim is subsequently approved after an appeals proceeding, the steps set forth in section 19.3 of this Part for an approved claim shall be followed.
