I am quite bitter about Aetna. We were getting "reasonable" reimbursement rates while belonging to an IPA group that contracted with Aetna. Aetna decided that they would no longer negotiate with the group but only with the individual practices. They approached me with the offer of paying at a rate of 50-60% Medicare reimbursement rates. Now this rate barely covers my overhead. We told them to go take a F... hike and never looked back. Aetna comprised 20% of my patient population when this happened. We did survive but can't understand how some of the local practices accepted their deal.
