Product-Specific J-Code for Omeros’ OMIDRIA® is Now in Effect

SEATTLE--(BUSINESS WIRE)-- Omeros Corporation (Nasdaq: OMER) today announced that the product-specific J-code for OMIDRIA^® (phenylephrine and ketorolac intraocular solution) 1% / 0.3% is now effective. OMIDRIA is Omeros’ commercial drug marketed for use during cataract surgery to prevent miosis and reduce postoperative pain.

The new permanent J-code for OMIDRIA, J1097, replaces the previous temporary C-code C9447. J-codes are reimbursement codes used by commercial insurance plans, Medicare, Medicare Advantage, and other government payers for Medicare Part B drugs like OMIDRIA that are administered by a physician. Availability of the new J-code is expected to expand reimbursement and enhance patient access to the clinical benefits of OMIDRIA, which, in a growing body of real-world evidence, has been shown to prevent intraoperative floppy iris syndrome, to decrease the incidence of sight-threatening cystoid macular edema and to reduce both the use of opioids and steroids.

Benefits of the new J-code include having one consistent billing code that can be used across all government and commercial payer plans as well as expanding coverage in state Medicaid and commercial plans that recognize J-codes, but not C-codes, for reimbursement.

CMS announced the new J-code for OMIDRIA in July, allowing time for Medicare Administrative Contractors as well as Medicare Advantage plans and commercial payers to program the new code into their systems in advance of the October 1 effective date. Omeros has confirmed that the new OMIDRIA J-code has been broadly uploaded to Medicare and commercial payer systems nationwide.

About Omeros Corporation

Omeros is a commercial-stage biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, complement-mediated diseases, disorders of the central nervous system and immune-related diseases, including cancers. The company’s drug product OMIDRIA (phenylephrine and ketorolac intraocular solution) 1% / 0.3% is marketed in the U.S. for use during cataract surgery or intraocular lens (IOL) replacement to maintain pupil size by preventing intraoperative miosis (pupil constriction) and to reduce postoperative ocular pain. In the European Union, the European Commission has approved OMIDRIA for use in cataract surgery and other IOL replacement procedures to maintain mydriasis (pupil dilation), prevent miosis (pupil constriction), and to reduce postoperative eye pain. Omeros has multiple Phase 3 and Phase 2 clinical-stage development programs focused on: complement-associated thrombotic microangiopathies; complement-mediated glomerulonephropathies; cognitive impairment; and addictive and compulsive disorders. In addition, Omeros has a diverse group of preclinical programs and a proprietary G protein-coupled receptor (GPCR) platform through which it controls 54 new GPCR drug targets and corresponding compounds, a number of which are in preclinical development. The company also exclusively possesses a novel antibody-generating platform.

About OMIDRIA^®

Omeros’ OMIDRIA^® (phenylephrine and ketorolac intraocular solution) 1% / 0.3% is the first and only FDA-approved product of its kind and is marketed in the U.S. for use during cataract surgery or intraocular lens replacement to maintain pupil size by preventing intraoperative miosis (pupil constriction) and to reduce postoperative ocular pain. OMIDRIA also is the only NSAID-containing product FDA-approved for intraocular use. In post-launch studies across conventional and femtosecond laser-assisted cataract surgery, OMIDRIA has been shown (1) to be effective in patients with intraoperative floppy iris syndrome (IFIS), pseudoexfoliation and other ophthalmic conditions, (2) to significantly reduce complication rates, use of pupil-expanding devices, and surgical times, and (3) to significantly improve uncorrected visual acuity on the first day following cataract surgery. While OMIDRIA is broadly indicated for use in cataract surgery, the above outcomes are not in its currently approved labeling. Surgical time was not an endpoint in the OMIDRIA Phase 3 clinical trials and did not reach statistical significance in post hoc analysis of the Phase 3 data.

Important Safety Information for OMIDRIA^®

Systemic exposure of phenylephrine may cause elevations in blood pressure. In clinical trials, the most common reported ocular adverse reactions at two percent or greater are eye irritation, posterior capsule opacification, increased intraocular pressure, and anterior chamber inflammation; incidence of adverse events was similar between placebo-treated and OMIDRIA-treated patients. OMIDRIA must be added to irrigation solution prior to intraocular use.
