CardioNet (Nasdaq: BEAT), announced today that on Friday, July 10, 2009, it received a letter from Highmark Medicare Services stating effective September 1, 2009 Highmark was adjusting its reimbursement rate for MCOT™ services to $754 per service. This reimbursement change affects all providers covered under CPT Code 93229.

Randy Thurman, Chairman, President and CEO of CardioNet, Inc., said, “CardioNet strongly believes that this reduction is unjustified and will immediately pursue with Highmark and CMS a methodology that appropriately values MCOT™ technology and related services. This review with Highmark and CMS will reinforce for Medicare the demonstrated benefit of Mobile Cardiac Outpatient Telemetry™ in detecting cardiac arrhythmias and improving the health of Medicare beneficiaries.

“We are strong proponents and supporters of the very real need to manage the cost of healthcare. We believe that early diagnosis through innovation in technology is fundamental to the provision of high quality health care and a cost efficient US healthcare system. Nearly 250,000 patients have been enrolled in MCOT™ to date with physicians and patients greatly benefiting from the CardioNet MCOT™ technology and service. We have made it our mission at CardioNet to educate the medical community about the value of wireless medicine in the diagnosis and detection of disease and we will further increase our efforts to demonstrate its potential to substantially lower costs to both patients and payors.”

CardioNet has previously indicated that while it had been aware Highmark Medicare Services was conducting a normal review of the reimbursement rate for MCOT™, it had received no indication of any rate adjustment or the specific timing of a Highmark decision prior to being notified on July 9, 2009. During a July 9 communication, Highmark reported that CardioNet would receive a letter notifying it of a change in reimbursement including the exact amount of the change. That letter arrived July 10, 2009.

Based on the Company’s ongoing discussions with Highmark and CMS and the Company’s desire for a re-evaluation of reimbursement that it is pursuing, but cannot assure will be realized, the Company believes it is prudent to withdraw previously stated 2009 guidance at this time.
