Shutdown Imperils Telehealth Access for Medicare Patients

Law360 Expert Analysis

The article discusses how the expiration of COVID-era telehealth flexibilities that had preserved expansive access to telehealth services for Medicare beneficiaries has created significant legal and financial uncertainty on health care providers and patients. Without a legislative solution, providers and patients are left in limbo on how to proceed. “Healthcare providers must decide whether to honor existing telehealth appointments for Medicare beneficiaries and must weigh the benefits of preserving access for a vulnerable patient population against the various financial and legal risks associated with the continued provision of telehealth services,” Conor and Danielle write. “The longer the shutdown persists, the greater the potential risk.”
