Berkeley Heights, NJ – June 6, 2024 – CorMedix Inc. (Nasdaq: CRMD), a biopharmaceutical company focused on developing and commercializing therapeutic products for life-threatening diseases and conditions, today announced that the Center for Medicare & Medicaid Services (CMS) has determined that DefenCath qualifies for pass-through status under the hospital Out-Patient Prospective Payment System (OPPS). Pass-through status provides for separate payment under Medicare Part B for the utilization of DefenCath in the out-patient ambulatory setting for a period of at least two years, and up to a maximum of three years.

While vascular access for hemodialysis can be initiated in an inpatient setting, ambulatory surgical centers or vascular access centers offer a less-invasive, outpatient-based alternative for patients. The company estimates that up to 100,000 HD-CVC placements occur each year, and pass-through status ensures that providers are reimbursed separately for administration of DefenCath in this setting of care. Given that approximately 50% of catheter-related bloodstream infections, or CRBSIs, can occur within the first 90 days that a catheter is inserted, it is critical to protect the line beginning at the time of placement.
