I work for a midwifery group and keep getting denied for assist at C-section whether I code 59515 or 59514 with modifier AS and/or 80. I live in Florida and by what I have read Florida Medicaid, of which they see a lot of patients, only allows for modifier 80? No matter how I bill I am denied is there something I am missing that needs to be added to the 1500 form; I have read something about a U code? Please help as I cannot find any answers on this and am very frustrated.
