If the surfaces do not touch on a multiple surface restoration would it be appropriate to bill two single restoration codes indicating the surface? (i.e. distal and mesial surface that are not touching) or would it be appropriate to bill 1 two surface code?
No, the code clearly states it is by tooth surface. Whether or not the decay touches has no bearing on the code.
