We do coding and billing for a radiologist out of a California hospital, most of his services (x-rays, CT scans etc) are billed with a 26 modifier, we have had no problems with the 36558 without a modifier (insert tun cath) until recently, they (Medicare) are now all of a sudden getting denied for missing modifier, I am confused as to what modifier is needed here. Any insight?
