If you live in Delta, Cedaredge, Paonia, Hotchkiss, or anywhere in Delta County, the single most avoidable Medicare mistake is signing up for Part B (medical insurance) too late. Do it without a valid reason and Medicare adds a permanent surcharge to your premium: 10% for every full 12-month period you could have had Part B but didn't. The good news — most people who kept working past 65 with real job-based insurance can avoid it entirely. This is education, not advice, but here is exactly how the penalty works in 2026, with every figure linked to its federal source.

How is the Part B late enrollment penalty calculated?

Your penalty is a percentage added to the standard Part B premium: 10% for each full 12-month period you were eligible for Part B but didn't sign up (and didn't have qualifying coverage). It's added to your monthly premium and, in most cases, stays there for as long as you have Part B.

Here's what that looks like against the 2026 standard Part B premium of $202.90. The percentage is permanent, but the dollar amount is figured on the current year's premium, so it climbs as premiums rise:

A 20% penalty is about $487 in extra premium over a single year — and you'd keep paying a version of that every year you have Part B. That's why the penalty is worth an hour of planning to avoid.

Who actually has to pay the penalty?

Not everyone who delays Part B owes a penalty. You owe it if you went without Part B and without other qualifying coverage during a period when you could have enrolled. You generally don't owe it if, during that time, you were covered by an employer group health plan based on current employment — yours or your spouse's — and you enroll within your Special Enrollment Period.

The distinction that trips people up in Delta County: the coverage has to be tied to a job someone is actively working. Two very common types of coverage do not protect you:

• COBRA — continuation coverage after you leave a job is not "current employment" coverage.
• Retiree health coverage — a former employer's retiree plan doesn't count either.

How do I avoid the penalty if I'm turning 65?

If you're not covered by active employer insurance, enroll during your Initial Enrollment Period (IEP) — the 7-month window that starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after. Signing up in that window means no penalty and no gap in coverage.

How do I avoid the penalty if I worked past 65?

Many people in and around Delta County keep working — on the farm, in local business, at the school district — well past 65 and stay on a job-based plan. If that plan is based on current employment, you have a Special Enrollment Period to add Part B:

1. While you're still covered by the active employer plan, you can sign up any month with no penalty.
2. For 8 months after that coverage or the employment ends — whichever comes first — you can still enroll penalty-free.

The trap: if you're on COBRA after leaving the job, your 8 months clock started when the employment ended, not when COBRA runs out. Wait for COBRA to end and you can blow past the window — landing both a coverage gap and a lifetime penalty.

Why does getting Part B right matter so much in Delta County?

Because Part B is what pays for doctor visits, outpatient care, and the ongoing treatment that manages chronic conditions — and those conditions are common among older adults here. A coverage gap isn't just a penalty; it can mean paying full price for care you'll likely need. Here's how common key conditions are among Delta County adults, per the CDC's PLACES county dataset (2023, model-based prevalence, age-adjusted):

With more than a quarter of Delta County adults managing high blood pressure and nearly one in four living with arthritis, Part B is coverage most residents will lean on. Signing up on time — and skipping the penalty — keeps that care affordable.
