Hi everyone! I recently moved here from Oregon so that my husband could attend grad school at OU. I recently started working at OUHSC and am trying to decide between the Aetna HMO or PPO. I am planning on getting knee surgery sometime this year, and trying to conceive sometime next year, so those two events are heavily influencing my decision. I am also trying to figure out if the higher costs associated with the PPO are worth the convenience. If anyone could let me know what their experiences were with either plan, I would really appreciate it!
