Code the following scenario according to ICD-10 coding conventions and guidelines:

Mary and Jack take a family vacation every year. However, due to Jack’s fear of flying, they typically drive and therefore have never vacationed out of the country. This year Mary wanted to do something different, but it would require them to fly instead of drive. Jack reluctantly agreed, as this trip would require him to face many of his fears. In addition to a fear of flying, Jack also had a fear of hospitals. And due to the area where they were traveling, it was essential that they get certain vaccines at the hospital.

On the morning of the flight, it was raining and thunderstorming. All Jack could think about were the tight quarters he would have to deal with for such a long flight. Jack hates thunderstorms and tight spaces. Before the flight took off, Jack had a panic attack in the airport. Mary always believed Jack was a hypochondriac, but she finally realized that his fears were real.
