Senior Medicare Advisors and it's website is not connected with or endorsed by any government entity or the federal Medicare program. SMA represents Medicare Supplement, Medicare Advantage HMO, PPO, and PFFS organizations and stand alone prescription drug plans that have a Medicare contract. Enrollment depends on the plan’s contract renewal. While we have a database of every Medicare plan nationwide and help you to search among all plans, we have contracts with many but not all plans. As a result, we do not offer every plan available in your area. Currently we represent 9 organizations which offer 75 products in Oklahoma. That said, we search and recommend all plans, even those we don’t directly offer, and the number of carriers and plans we offer in your specific zip code may be different. Please contact Medicare.gov, 1-800-Medicare, or your local State Health Insurance Program (SHIP) to get information on all of your options.
