Does anyone know if code(s) 92235 and 92240 are bilateral or unilateral? My understanding is that the codes can not be billed with a 50 modifier, but can be billed with a 52 - LT or RT. This would lead me to believe they are bilateral. I am getting conflicting information from various sources and the coding books do not clarify if the codes are bilateral or unilateral. Any clarification is greatly appreciated! Thanks.
