A claim should be asserted when the Air Force has furnished or will furnish medical care in military health care facilities or when the Air Force is responsible for reimbursement to a private care provider and either of the following conditions are met: A claim should only be asserted if the base SJA determines it merits assertion. Claims for $150 or less need not be asserted; they should be asserted only if the base SJA or designee determines the collection will not exceed the cost to collect, the third party offers payment and demands a release from the United States before paying damages to the injured party, or the United States asserts a property damage claim under subpart L arising out of the same incident.
