Its not a rail to rail OPAMP and the datasheet specs the common mode input range as min. +/-12V, typ. +/-13V with a +/-15V supply. That means that, worst case, it will malfunction if either input goes within 3V of the supply rail, and by the time you get to 2V from the rail, you've got 50% odds of it malfunctioning. It certainly isn't rated for operation with its inputs outside the rails.
However, you've also misunderstood its supply volttage ratings. Its specced for an abs. max. supply voltage of +/-22V, which means two rails with 44V between them. That would be pushing your luck for normal operation, but I'd certainty expect it to behave with +/-18V supplies, which is 36V between the rails. The only fly in the ointment is the differential input votage rating of +/-18V so if one input is up near the rail, (say 3V below Vcc), the other cant be more than 18V negative of that, which is far above the Vee rail voltage if you are running it from +/-18V rails. At supply voltages above +/-9V you risk destroying it if you ever take its inputs to opposite rails.
Its possible to work around these limitations by clever circuit design, and diode clamping to protect the inputs, but that requires multiple matched precision resistors, so its probably better to use a different OPAMP.
You'd better provide a block diagram showing exactly where you want to put the current sense resistor, and what supply rails are available, so we can advise you what the options are.
