Setoff for cost of unauthorized medical treatment. In any tort claim administratively settled or compromised where the claimant owes the Department of Veterans Affairs for unauthorized medical treatment, there will be included in the tort claim award the amount of the claimant's indebtedness to the Government. The amount of the indebtedness is for credit to the appropriation account from which the services were provided. The voucher prepared for settlement of the claim will specify the amount to be deposited to the credit of the designated account and that the balance of the award be paid to the claimant.
