Could someone please help me? My surgeon done a bilateral partial mastectomy with axillary lymphadenopathy for a woman with bilateral breast cancer. I have tried to code it multiple ways, and I have denials from only 1 of these is allowed per day, to incorrect modifier. I have tried to code it on 2 lined with a left and right modifier, tried 1 line wit 1 and a 50. The last time I used 78, 50 and 59. The 78 because she had the breast biopsy a few weeks earlier. I have never had so much difficulty. If someone could help me I would greatly appreciate it. Thank you in advance
