Who does lab work for Aetna and how is it covered?
Aetna has a contract with Quest Diagnostics. If the doctor is in the network, his/her contract specifies that he/she must use the lab to which Aetna has contracted. Lab work is covered at 100%. If you are in the POS plan and use an Out-of-Network doctor, the office can send lab work to any lab and you are responsible for 20% of the charge if it is any other lab than Quest.
