Supplement Plans F, G, and N Similarities
In terms of coverage, all of these plans cover the Part A coinsurance and hospital costs up to an additional 365 days after Medicare benefits are used up, the Part B coinsurance or copayment, the first 3 pints of blood, the Part A hospice care coinsurance or copayment, Skilled nursing facility care coinsurance, the Part A deductible, and foreign travel exchange (up to plan limits).
As for your out-of-pocket costs, a similarity across these plans is that the insurance company charges a monthly premium for the policy. The types of price structures (i.e. community-rated, issue-age rated, and attained-age rated) can vary.
Supplement Plans F, G, and N Differences
While these plans do have their similarities, they also have their differences. For example, eligibility for Plan F is not an option for people who were newly eligible for Medicare on or after January 1, 2020. But as long as you have Original Medicare and apply during Medigap Open Enrollment, you should be able to get Plan G or Plan N. Another difference is that Plans F and G also provide high deductible options, which can be useful if you have considerable retirement savings.
In regards to coverage, Plan F also covers Medicare Part B deductibles and Plans F and G cover the Part B excess charges. Plan N also has a slight difference in coverage, like how it covers Part B coinsurance or copayment. Under Plan N, participants have to pay a copayment of up to $20 for some office visits and up to a $50 copayment for emergency room visits with no inpatient admission — before Plan N pays for Part B coinsurance.
Then there are the out-of-pocket costs. Even though the plans may have similar pricing structures, there could be price differences among the three plans. Typically, the more coverage there is, the higher the premiums will be.
