Just got a denial from UHC on outpatient therapies i.e occupational and speech, The reason code stated that it is not billed according to the Medicare guidelines. The codes in question are 92526 and 97535 both of em had GN and GO modifiers appended to em respectively but the 92526 also had KX modifier. Adding to that I had the same bill for the same patient for the same procedures but different dates and that one got paid and the only difference was it didn't have any KX modifier with 92526.
