Has anyone else had problems with molina denying claims for diagnosis on a placenta biopsy? I could use a little guidance here. I hope someone can help. We received a di/di placenta delivered by c-section for biopsy with a 88307 cpt code and a diagnosis of dystrophic microcalcifications. We billed it with a diagnosis of 656.71, 654.21, and v91.03. They have denied it for incorrect procedure code/diagnosis. Can someone help before i have no hair left. I would be grateful for any input.
