Narrative:

We were cleared to FL200. Upon clearance, I inadvertently set FL220 on altitude alert. Copilot was flying. I was looking at GPS. Center called and asked altitude. At that point I realized I had set FL220 on alerter. Altitude was FL205 when called by center. Went back to FL200. Center told me to call, which I did approximately 2 hours later after flight. Incident happened at busy segment of flight.
