I agree with iowa boy. I'm pretty sure that UPS switched part-time medical insurance from Aetna to Blue Cross / Blue Shield effective January 1, 2010. Only certain states made the switch, some remained unchanged. Perhaps you work in one of the states that changed. Call Human Resources to verify this, then have the medical provider who billed Aetna resubmit the bill to your new insurance plan. Good Luck. Let us know how it all turns out.
