Medicaid is a joint federal and state program that provides healthcare coverage to eligible individuals with limited income and resources. The specific coverage of medical equipment and services, including bedside commodes, can vary by state. 

In the case of Washington, D.C., Medicaid does cover bedside commodes if they are medically necessary and prescribed by a healthcare provider. However, coverage may be subject to certain limitations, such as the type of commode, the frequency of use, and the length of coverage. 

To determine the specific coverage of a bedside commode under DC Medicaid, patients or their caregivers should consult with their healthcare provider and insurance plan or contact the D.C. Department of Health Care Finance for more information.
