Frequently asked questions
Where do these answers come from?
Each answer is based on Medicare.gov, CMS rules and data, Social Security, the Oklahoma Health Care Authority, the Oklahoma Insurance Department, OKDHS, OMES, OTRS, IHS, TRICARE and Oklahoma law, and lists its sources at the bottom of the page. Medicare's rules are federal, so most answers apply nationwide; each page explains where Oklahoma programs or geography change the picture.
Who can answer a question about my own situation?
1-800-MEDICARE (1-800-633-4227) and Medicare.gov answer questions about Medicare itself, Social Security handles sign-up and Part B premiums, and the Oklahoma Health Care Authority handles SoonerCare. For help comparing plans from the companies they work with, you can request a call from a licensed insurance agent, at no cost to you.
Are 2027 amounts on these pages?
Where CMS has published them. CMS publishes the 2027 Part A, Part B and IRMAA amounts in the fall; until then the pages give the 2026 amounts and say so. The 2027 Part D limits are already published.
How often are the answers reviewed?
Every page shows the date it was last reviewed by the Benefits Life Editorial Team. Pages are reviewed each fall when CMS publishes the next year's figures and plans, and whenever a federal or Oklahoma rule changes.
