One thing to think about, a big thing, I think, is to know the pricing type that you're buying into. This doesn't make much difference if you stay healthy and can bail out of the sick duck pool if the prices go up too much, but if you become a sick duck, you're stuck, so it might be wise to pick a big pool with lots of people that aren't fleeing.
There are 3 pricing models. There are variations, but the pricing generally goes like this:
In community rating, the same monthly premium is charged to everyone who has
the Medigap plan, regardless of age. Premiums may rise due to inflation, but not
due to the beneficiary aging. Issue‐age rated premiums depend on the age of the
beneficiary when purchased, but again, they do not rise due to aging. Attained‐
age rated premiums, conversely, rise as the beneficiary ages.
AARP is a hybrid, where it's community rated, but has a built-in 3% increase every year, plus whatever amount they need to in order to keep the books in balance. Unless mentioned, everybody below is using "attained age pricing".
I called 6 companies today and got a wide variety of responses. My goal was to get a price for a female in my county turning 65 in March 2022, no tobacco. That's all they need to know to give me a price.
AARP UnitedHealthcare: Real person reached, but seemed more interested in getting specifics on the individual (name, address, DOB, etc) than giving me prices. I said I just wanted to understand what they were offering and the prices, but they wouldn't provide the information. I asked basic question about "Standard" and "Level 2" options (listed on the medicare site), and they wouldn't even explain the difference. And they wouldn't explain what "Household" meant. They did give me a web site address and I looked-up the prices myself. I noticed that if you want to continue the nightmare, you can choose a "Select" plan, which puts you into a limited network (shudder). With Non-"Select" with "Household" G$87, N$68, K$45, increasing at least 3% as far as the eye can see.
TransAmerica: Real person that listened to my questions and responded to me. Didn't seem to have an alternate agenda. Described pricing of "issue age pricing" and indicated that this pricing was enforced by the state and that everybody in the state with that letter paid the same thing. G$147, N$111, K$64.
Physicians Life: Recording "emergency situation, call back in an hour". Tried that, same message. This company also has issue age pricing, which is why it made it to my list. Most companies don't offer this pricing model. According to the Medicare web site, this company offers both "issue age" and "attained age" and also has "innovative" priced of both of those. I thought the pricing here might be interesting. They have high deductible G as well. Too bad they didn't pick up the phone.
BlueCross BlueShield NC: Got a guy who seemed annoyed that he couldn't just take my order for a medigap policy. He said the pricing was on the web site, and I obliged him by taking that and ending the call. The web site had a feature of their letter plans called "Blue to Blue", which says that at certain times of the year, you're allowed to switch to a different letter or into a traditional medicare from an advantage plan without underwriting. They didn't say what the pricing would be in such cases, but that seems like it might be a negative; if people can shift around, then they can go cheap until they get sick, then go full service later, and that would have lots of high utilizers clumped together, driving high prices. But I'm not sure how they're doing the pricing with this scheme. Needs more research. G$100, N$90, K$67, Ghd$38.
Mutual of Omaha: I don't remember what happened on the phone, but ended up on the web site, which seemed to be pushing pretty hard for people to go through an agent. So we have agents like BoomerBenefits pushing MoO and we have MoO pushing for agents to be involved. Hmmmm. Call me skeptical. I don't like to have things sold to me...I'd much rather buy them. G$94, N$71, Ghd$31.
Colonial Penn: This company had G, N, K, Ghd on the Medicare site, so decided to give them a shot. The number from the Medicare site led to a really nice guy who admitted he didn't have pricing and could not sell me a policy. Seemed very knowledgeable and in fact led me through the basics (that I already knew, but he talked, I listened). He gave me two phone numbers to call if I wanted to get pricing. The first led to an overseas call center. Demanded personal information before they'd give me pricing. I excused myself from that call and called the next number. Same script, same refusal to give prices.
