Billing for COVID-19

Modifier CS was designated by the Centers for Medicare & Medicaid Services to be used to identify applicable services subject to the cost-sharing waiver during the federal COVID-19 Public Health Emergency (PHE). As the PHE ended on May 11, 2023 and CarePartners of Connecticut returned to many pre-pandemic operations and policies, modifier CS should no longer be used. Claims submitted with modifier CS appended may result in a claim denial.
