SAVIENT PHARMACEUTICALS RECEIVES J-CODE FOR KRYSTEXXA^(R)

KRYSTEXXA is the first and only FDA approved treatment for RCG

EAST BRUNSWICK, N.J. - November 3, 2011, - Savient Pharmaceuticals, Inc. (Nasdaq: SVNT) today announced that the Centers for Medicare and Medicaid Services (CMS) has assigned a product-specific billing code, or J-code, for KRYSTEXXA^(R) (pegloticase), which is used for the treatment of chronic gout in adult patients refractory to conventional therapy. The new J-code, J2507, becomes effective on January

“This is an important milestone for Savient, and we are very pleased that CMS has issued a J-code for KRYSTEXXA,” said John H. Johnson, Chief Executive Officer and President of Savient Pharmaceuticals. “While it may take three to six months from its effective date for the J-code to be loaded into the entire payer system, the J-code should enable more rapid reimbursement for providers. The J-code should facilitate reimbursement for providers who treat patients suffering from the severe and debilitating disease of refractory chronic gout and who rely on Medicare and Medicaid.”
