@relentlesslyawesome F always was and still is more expensive than G. And the premium surcharge is PARTLY to cover the Part B premium but that is not the only reason.
Until 2020 the F plan was over-promoted by carriers and agents because it was an easy sale. All approved claims are covered at 100%. How easy is that?
Shoppers who bought direct from carriers were pushed into F plans with nary a word about the competitively priced G plan. Consumers trusted the carrier to do right by them, so they bought into the plan like sheep.
To be fair, even though the G plan has been around for over 20 years many of the big name carriers did not have the G plan in their portfolio until a 3 or 4 years ago.
They can't offer you something they don't have, so . . .
But the F plan was priced higher than the Part B deductible for the simple reason the F plan took the brunt of heavy claim users. Applicants with certain SEP's were able to get an F plan without medical underwriting. Even if the carrier offered a lower premium G plan if the applicant was not in an "open enrollment" period and could not pass underwriting the default was plan F.
Short translation - sick people went into the F plan, healthy folks into G.
Every once in a while I run into folks with an F plan and are paying outrageous premiums. If they are healthy enough to pass underwriting, some won't give up their F plan because they foolishly believe they can never get it back.
In general, the F plan block is getting older and sicker. Healthy folks leave and the sick ones stay. Plan F blocks will go into a death spiral within a few years.
Bark less. Wag more.
