Central Kentucky Ear, Nose and Throat will drop its Aetna-insured patients when the practice becomes associated with Lexington Clinic later this year.
Lexington Clinic dropped its Aetna patients in 2010.
Aetna spokesman Scot Roskelley said that Aetna had not been negotiating with Central Kentucky ENT and had not heard of the organization affiliating with Lexington Clinic.
Aetna has 93,000 members in Kentucky.
Asked whether dropping Aetna patients is a reimbursement issue, Lexington Clinic spokeswoman Michelle Sjogren said the practice's mission "is to provide the highest-quality medical services at a reasonable price to the patient, so we balance all aspects of contractual agreements, as would any responsible business. At times, we must make difficult decisions such as this in order to meet this mission."
Sjogren said Lexington Clinic had worked to find agreement with Aetna and "is always open to discussion with Aetna that will facilitate an agreement that allows Lexington Clinic to provide the highest-quality medical services at a reasonable price to the patient."
More than 400 letters were sent to Aetna-affiliated patients of the Central Kentucky ENT practice. That represents about 2 percent of the practice's patients, Sjogren said.
Central Kentucky ENT has offices at Central Baptist Hospital, in Hamburg in Lexington, and in Richmond and Frankfort.
