This plan doesn’t cover Part A and Part B deductibles so you’ll need to cover those costs. Your average cost can be 110 to 180$ dollars per month. Those costs are variable and some factors like age, gender, living area, enrollment period, etc. can impact your supplement rates.
This plan can be good if you are looking for lower monthly premiums and don’t travel abroad. However, notice that your out-of-pocket hospital costs will be much higher.
