Palatin Technologies Announces Issuance Of A Medicare Reimbursement Code For NeutroSpec(TM)

CRANBURY, N.J., Jan. 24 /PRNewswire-FirstCall/ -- Palatin Technologies, Inc. announced today that the Committee for Medicare and Medicaid Services (CMS) has established a temporary HCPCS (Healthcare Common Procedure Coding System) reimbursement code for the payment of NeutroSpec. This reimbursement code for NeutroSpec allows Medicare reimbursement for infection imaging in an outpatient setting. NeutroSpec is Palatin's proprietary radiolabeled monoclonal antibody product for imaging and diagnosing infections.

"This is a significant milestone in the commercial development of NeutroSpec," said Carl Spana, Ph.D., President and CEO of Palatin Technologies. "The issuance of this reimbursement code is an important, initial step in ensuring broad reimbursement coverage for NeutroSpec as we continue to work in conjunction with Mallinckrodt Imaging, our strategic collaboration partner, to maximize NeutroSpec's commercial value."

CMS issues temporary HCPCS codes while permanent HCPCS codes are being established, a process that usually takes six to twelve months. CMS issues permanent HCPCS codes for medical technologies that may be reimbursed by Medicare and Medicaid. Private health insurance companies use these codes as a reference point in establishing their position on reimbursement coverage of new medical technologies like NeutroSpec.

About NeutroSpec(TM)

NeutroSpec(TM) is Palatin's proprietary radiolabeled monoclonal antibody product for imaging and diagnosing infections. NeutroSpec is marketed and distributed by Palatin's strategic collaboration partner, Mallinckrodt Imaging, a business unit of Tyco Healthcare. NeutroSpec has been approved by the FDA as an imaging agent for the diagnosis of equivocal appendicitis. The Company is also conducting additional clinical trials with NeutroSpec to evaluate its market potential as an imaging agent for other indications.

NeutroSpec includes a technetium-labeled anti-CD 15 monoclonal antibody which selectively binds to a type of white blood cell, neutrophils, involved in the immune response. When injected into the blood stream, NeutroSpec binds to neutrophils present at the infection site, labeling these cells with a radioactive tracer. As a result, physicians can rapidly image and detect an infection using a gamma camera, a common piece of hospital equipment that records radioactivity. NeutroSpec offers the advantage of direct injection and in-vivo labeling of white blood cells, leading to a rapid and highly specific functional image of an infection in less than an hour, whereas the current standard of care, ex-vivo labeled white blood cells, requires a blood sample to be taken from the patient, processed by a nuclear pharmacy and then re-injected into the patient, with diagnostic images usually not available until 12-24 hours later.
