Part B Premium in 2026: What New Mexicans Should Know
The 2026 Part B premium of $202.90/month is a $17.90 increase from 2025's $185.00. For most New Mexicans, this premium is deducted directly from your Social Security check. If you have limited income, you may qualify for a Medicare Savings Program that pays part or all of your Part B premium.
