Kidney Patient Access to Technologically Innovative and Essential Nephrology Treatments Act of 2023 or the Kidney PATIENT Act of 2023 This bill delays a change to the payment methodology under Medicare for oral drugs that are used to treat end-stage renal disease (ESRD). Under current regulations, beginning January 1, 2025, the Centers for Medicare & Medicaid Services will incorporate payments for oral-only ESRD drugs into the ESRD prospective payment system rather than issuing separate payments to ESRD facilities. The bill delays implementation of this policy until January 1, 2033, or until an approved intravenous drug is available, whichever is earlier.
