Yes they are compatible. The D7200 is a DX camera and that lens is a DX lens. You can also use FX lenses on the D7200, but when you do that the focal length ends up bing about 1.5x what it says on the lens due to the fact the D7200 is a crop sensor and the FX lenses are for full frame. You buy a 10-24 on and FX lens that would be like a 15-36 in a DX lens. I personally have this lens and use it for wide angle shots with my D500.
