Narrative:

ATC facility: ZKC. Location: about 50 mi southwest of mci. After attempting 2 approachs to mci during heavy snow, we were diverting to ict. Both the captain and I were very busy communicating with dispatch, ATC, reprogramming FMC, and flying the airplane. During this time we missed resetting the altimeter to 29.92, which went unnoticed until ATC mentioned that he showed our altitude to be 400 ft high. We corrected our altitude and no conflict occurred. The solution to this problem, as always, is to fly the airplane first and take care of the other priorities when there is time. Supplemental information from acn 350759: I believe factors that contributed to this error were: crew fatigue -- a minimum of 8 hours rest the previous night, the added stress of 2 minimum approachs to misses in turbulence, and the removal of first officer from cockpit duties to communicate via ACARS with dispatch.
