Altitude and heading was assigned at the same time. Heading assigned 160 degrees was mistook for altitude 16000 ft. Passing through 14000 ft, called center to confirm 16000 ft. Center reply altitude was 13000 ft and heading 160 degrees -- no conflict. Immediately cleared to FL230 direct NAVAID and frequency change.
