Medicare and Medicaid may provide coverage for bed rails in certain circumstances, but coverage policies can vary depending on the state and the specific situation. 

In general, Medicare Part B may provide coverage for durable medical equipment (DME), including bed rails, if they are deemed medically necessary by a healthcare provider and if the patient meets certain eligibility requirements. Medicare Part B typically covers 80% of the cost of approved DME, and the patient is responsible for paying the remaining 20%. 

Medicaid is a joint federal and state program that provides healthcare coverage to eligible individuals with low income and limited resources. Medicaid coverage for bed rails may vary by state, but in general, Medicaid may cover DME, including bed rails, if they are deemed medically necessary by a healthcare provider and if the patient meets certain eligibility requirements. 

It is important to note that coverage policies can vary by state and by individual circumstances, and it is important to consult with the patient’s healthcare provider and insurance plan to determine the specific coverage policies and eligibility requirements for bed rails. In some cases, prior authorization may be required before coverage will be approved.
