Looks like the only difference with Plan G is a very small co pay and no excess charge coverage (8 states don’t permit excess charges) looks like the premium is about 2/3 of what G is.
And it seems the premiums don’t increase as much as the others.
I have been comparing them too Plan N makes a lot of sense if you want strong coverage but with lower premiums, and the copays haven’t been a deal-breaker for me so far Good choice for many people as long as you are okay with potential excess charges and the occasional office visit copay.
