What is AAC 31?

• A. currently in the process for retention evaluation
• B. assign to outpatient therapy
• C. awarded for flight duty
• D. mobility restrictions that lasts greater than 30 days are automatically placed; indicates that the condition + the restrictions are expected to last more than 31 days

Answer: (D)

In flight medicine, AAC codes are used to quickly communicate medical restriction details and their likely duration. AAC 31 specifically flags mobility restrictions that last more than 30 days. It is an automatic designation that indicates the condition and its restrictions are expected to persist for more than 31 days. This code serves as a communication tool to alert medical evaluators and command that the individual has a mobility limitation of extended duration, which can impact duty status and require longer-term medical management.

It isn’t about being awarded for flight duty, nor about being assigned to outpatient therapy or a retention evaluation by itself. Those are separate processes or actions; AAC 31 is a status indicator signaling an extended mobility restriction and its expected duration.
