CardioNet Inc. (BEAT) said a regional administrator of Medicare services confirmed it will cut its reimbursement rate for mobile cardiovascular technology Sept. 1.

The rate - $754 per service - is 33% less than the rate HMS published in May.

CardioNet's shares sank 15% to $6.12 in after-hours trading as the pioneer in remote monitoring of heart patients said it would not provide guidance because of the impact that the lower rate would have on its business. The stock is down about 70% this year.

Last month, CardioNet's shares fell sharply after it disclosed that Highmark Medicare Services had proposed the lower reimbursement rate for a monitoring program using CardioNet's technology.

A Highmark spokesman said then that the company establishes such rates after careful evaluation of Medicare requirements.

CardioNet Chief Executive Randy Thurman has estimated that similar monitoring in hospitals costs $26,000.

The company said Monday that it intends to comply with Highmark's offer for it to provide additional information that Highmark would review it in a reasonable time and adjust the rate if appropriate.

"We will be persistent in pursuing every appropriate means to remedy this situation," Thurman said.
