Most houses run 12 gauge wire for outlets and that will be enough for a 20 amp circuit. First is to check the existing wire gauge for the circuit in question. Then, note the type of 12 gauge wire used as different types are capable of carrying more amperage. The lowest amperage wire, NM-B or UF-B, will handle 20 amps. THW, THWN, can handle 25 amps.
In short, you may not need to change the wiring if you have a 12 gauge circuit already.
