We are having issues with our urinalysis code 81003 bundling to the e&m code. We bill out the 81003 with a QW and we've even tried adding a 25 modifier on the e&m code and they still bundle it. I've tried contacting the insurance carriers and they won't tell me anything. I ran it though a claim check system on one of the carrier's websites and the only modifier it would go through with was a 59 which I've been told is a incorrect modifier to use. Does anyone have any suggestions?
