Medicaid Office Contact Numbers

The Centers for Medicare and Medicaid Services (CMS) offer many helpful options to resolve any Medicaid questions or issues.

Additional information and assistance can be found at the website and the individual state Medicaid websites (see our “Medicaid by State” page). Rona Daniels recently joined our Louisiana team after serving in New Orleans for several years as a maritime lawyer for a noted local legal practice. Her mission was to advocate on behalf of local workers injured on the job in the port or on ships and rigs. She is familiar with the specific state requirement and her legal expertise is a welcome addition to her overall knowledge of Medicaid.

Generally, the best place to start is the Medicaid office of your particular state — most of the numbers listed here are for program issues and general questions and information. The last time I visited a local Medicaid office one afternoon, I had spent that morning looking at an e-commerce drapery store trying to select some designer Roman Shades for the windows in my mother’s nursing home room. Actually “designer” makes this online store sound pretty high end. But it was really an online custom drapery store that allows its customers to select beautiful window coverings, in my case Roman shades, and then have them sewn to the specifications you select. The end results are pretty spectacular and will correctly fit the measurements of the windows. Anyway, when I walked into the Medicare offices, I can tell you, their window coverings were the “basic basics” purchased at some low end wholesaler, I would guess. Their curtains / shades were functional is all I can say. However, I was able to get the help I needed and was on my way only 2 1/2 hours later. Calling might be a better option, unless you live nearby.
