CMS Establishes Unique J-Code for Eagle Pharmaceuticals' PEMFEXYtm (Pemetrexed for Injection)

Eagle Pharmaceuticals, Inc. ("Eagle" or the "Company") (NASDAQ: EGRX) today announced that the Centers for Medicare & Medicaid Services (CMS) has established a unique, product-specific billing code for PEMFEXYtm (pemetrexed for injection). This new Healthcare Common Procedure Coding System (HCPCS) code, or J-code, is J9304 (Injection, pemetrexed (PEMFEXY), 10 mg). The J-code will become effective on October 1, 2020.

The new HCPCS code provides coding clarity to outpatient facilities and physicians who will administer PEMFEXY, facilitating access for patients and reimbursement from Medicare, Medicaid and commercial insurance.

In February 2020, Eagle received final approval of its New Drug Application (NDA) from FDA for PEMFEXYtm, a branded alternative to ALIMTA^®, following settlement of patent litigation with Eli Lilly and Company. The Company is entitled to initial market entry (equivalent to approximately a three-week supply of current ALIMTA^® utilization) on February 1, 2022, and a subsequent uncapped entry on April 1, 2022.

The Company also received a supplement approval from FDA for a 500mg multiple-dose vial of PEMFEXY on June 18, 2020.
