I would like to alert readers regarding Aetna PPO denial of claims and reimbursement decrease practices. In 2010, Aetna PPO Health Insurance tried the following to eliminate/ reduce claims from my husband's providers:- 1) Arbitrarily decided that he had other primary insurance and denied all claims after a date chosen by them. 2) Arbitrarily applied a 75% discount to bills previously paid in full. It seems that a discount program was erroneously applied to the provider. The reduction came to light when the provider billed us for the difference. Both of these were eventually resolved but only after hours and weeks of phone calls. read full review »
