When I was ready to pull out what little is left of my hair in dealing with maddening insurance panels, I put out an urgent call to colleagues. I asked them to recommend someone who could help me with the panel bureaucracies, with whom I might also contract for billing if the work went well. I received several recommendations for Ceci Martinez at Advantedge Billing. I made an appointment with Ceci and she was so helpful, so no-nonsense, so knowledgeable, and made the process so simple, that I have never looked back. She has been an enormous amount of help in joining and maintaining my membership with insurance panels, in renegotiating my reimbursement rates whenever possible, and in keeping abreast of critical updates. She has made the billing process smooth and minimally stressful for me. Her rates are reasonable and worth every penny. I honestly don't know what I'd do without her. I am deeply grateful for all her work with me, and recommend her highly.
