Medicare Supplement policies are standardized by plan letter.
Medicare Supplement plans are identical by federal law, so that price comparisons can easily be made between all companies offering identical coverage.
"Medigap must follow federal and state laws designed to protect you,
and they must be clearly identified as “Medicare Supplement Insurance”. Insurance companies can sell you only “Standardized” plans, identified... (by plan letter)".
It's Apples to Apples.
The coverage is exactly the same with every company, as determined by plan letter.
Every company that offers a "Plan F" has the exact same benefits as every other company with a "Plan F". The same applies for "Plan G" and "Plan N", and so on.
