Pittsburgh Medigap in 2027: the plan letters, the Part B reset, and rate filings to watch

PITTSBURGH — As 2027 approaches, Medigap shoppers in Pittsburgh are looking at a familiar but moving picture: the same standardized plan letters, a Part B deductible that resets every January (and drives how Plans G and N pay), and a rate-filing season at the state level that can nudge premiums up or down before the new year begins.

Nothing about Medigap is decided at the city line. Pittsburgh sits in Allegheny County, and Medigap is regulated by the Pennsylvania Insurance Department, so what changes here is really what changes across the state. Here is what to keep an eye on.

The plan letters available in 2027 haven't changed

If you are turning 65 or otherwise becoming newly eligible for Medicare in 2027, the menu of standardized Medigap letters you can choose from is the same one you would have seen this year: A, B, D, G, G-HD, K, L, M, and N. Plans C and F are still on the shelf, but only for people whose Medicare eligibility date is before January 1, 2020. That rule comes from federal law and is not expected to change in 2027.

Every insurer that sells "Plan G" has to sell the same Plan G benefits — that is what "standardized" means. What differs between companies is the premium, the customer service, and any small extras (like a fitness perk) that ride alongside the core policy.

The Part B deductible reset — why it matters for Plans G and N

Plans G and N, the two most popular letters for new enrollees, are structured around the Medicare Part B deductible. With either plan, you pay that deductible out of pocket once a year, and after that the plan picks up most of what Part B doesn't cover (Plan N still leaves some office and ER copays and any Part B excess charges to you).

Every January, that deductible resets and CMS sets a new figure for the year. The 2027 number will be published by CMS in the fall of 2026. When it comes out, that becomes the amount Plan G and Plan N enrollees will pay before their Medigap benefits kick in for the year. Watch medicare.gov or your Medicare & You handbook for the announcement.

Rate-filing season: how 2027 premiums get set

Medigap premiums are not set by Medicare. In Pennsylvania, each insurer files proposed rates with the Pennsylvania Insurance Department, which reviews them before they can take effect. That review typically happens in the months leading up to the plan year, which means late 2026 is when most 2027 Pittsburgh-area rates are being locked in.

Two things are worth knowing:

• Rates can change on your existing policy, too. Even if you don't switch, your carrier can raise (or occasionally lower) your premium when your renewal comes around, subject to state review.
• Same letter, different price. Because benefits are standardized, comparing carriers on price for the same letter is straightforward — but you have to actually compare. The Medicare.gov Medigap policy search lets you enter a Pittsburgh ZIP code and see every carrier offering each plan letter in your area, along with premium ranges.

The Pennsylvania Insurance Department also publishes a Medigap rate guide that lists filed premiums by carrier and by age band. It is one of the clearest ways to see what has moved for 2027.

Insurers entering or leaving Pennsylvania

Unlike Medicare Advantage, where CMS publishes plan exits and entries every fall, Medigap carrier changes in Pennsylvania happen quietly through state filings. A company can decide to stop selling new Medigap policies in the state, or a new one can enter — and the way you find out is either a letter from your current carrier or a fresh listing (or missing listing) in the state rate guide and on Medicare.gov.

If you get a notice that your insurer is exiting the Pennsylvania Medigap market, your existing coverage generally continues under the terms of your policy, but you may want to shop. In most cases, once you are past your initial Medigap open enrollment window, switching plans in Pennsylvania can involve medical underwriting — so it is worth talking to APPRISE before you cancel anything.

What Pittsburgh shoppers should do before January

A short checklist for the weeks ahead:

1. Look up your ZIP code on the Medicare.gov Medigap policy search to see every carrier selling each plan letter in Allegheny County. 2. Pull the Pennsylvania Insurance Department's Medigap rate guide for 2027 premiums by carrier. 3. Watch for the 2027 Part B deductible announcement from CMS — that is the number Plan G and Plan N enrollees will pay first each year. 4. If you have a Medigap policy already, read any renewal notice carefully for a new premium. 5. Call APPRISE (Pennsylvania's SHIP) at 1-800-783-7067 for free one-on-one help.
