Can anyone assist me? I have been having difficulty getting MCR to pay for sleep studies 95810, 95811 if less than 6 hours. According to their LCD it states 6 hours of recording with no mention about what to do for less than 6 hours. But according to CPT AMA if less than 6 hours you need to append modifier 52. When we do this they deny for inaccurate billing and say the claim isn't appealable. What are others doing when getting less than 6 hours recording time. I find it unfair that we should not get reimbursed because the patient didn't sleep therefore not getting sufficient data. Some patient even refuse to stay hooked up for the 6 hours if they cannot sleep. The only option I have thought of was having patients sign an ABN to cover us and state reason would be not being able to sleep as a reason for denial? If anyone can offer assistance on this, that would be very much appreciated. Thanks!!
