This morning I inquired with Aetna about getting breast augmentation and this was their response:

Dear Angelina:

Your Plan
Under your plan, breast implants services from home host providers are
covered at 100% after copayment of $50.00 and participating providers
are covered at 80% of the network negotiated charges after you meet an
annual in-network deductible of $350.00. However, breast implants
services from non-participating providers are covered at 60% of the
reasonable charges after you meet an annual out-of-network deductible of
$2,000.00.

You would need to have your attending doctor call the pre-certification
number that is on your identification for inpatient.

Determining coverage
Coverage for services is based on your plan and certain clinical
criteria called a Clinical Policy Bulletin (CPB). Please be sure to
review and discuss the CPB with your doctor.
