CMS-1844-F provides the final CY 2027 home health payment update, including rate changes and recalibration that affect Medicare home health spending. For a cost topic, the rule matters because it sets the payment structure for a major post-acute benefit and can influence both provider revenue and federal outlays. It is materially different from already published titles because it addresses home health payment policy rather than hospital, physician, Medicaid managed care, or laboratory payments.
