Medicare Supplement Plan L Costs

Medicare Supplement Plan L (also called Medigap Plan L) is the “I want a safety net, but I’m not trying to pay for the deluxe velvet rope” option in the Medigap family. It can lower your monthly premium compared with more comprehensive planswhile still giving you something Original Medicare famously doesn’t: a cap on certain out-of-pocket costs.

But “Plan L costs” aren’t just one number. They’re a mix of (1) what you pay every month no matter what, and (2) what you pay when you actually use care. This guide breaks both down with real math, plain-English examples, and the gotchas that trip people up when they’re comparing plans.

Quick refresher: what Plan L is (and what it isn’t)

Medigap plans work only with Original Medicare (Part A and Part B). They help pay some of the deductibles, coinsurance, and copayments that Original Medicare leaves for you. Medigap plans are standardized by letter in most states, meaning Plan L benefits are the same no matter which company sells it (price is what changes).

Important: In Massachusetts, Minnesota, and Wisconsin, Medigap plans are standardized differently, so “Plan L” may not exist in the same way there.

What Plan L covers (the “75% plan” with a stop-loss)

Plan L is best understood as a plan that covers 100% of some big-ticket hospital coinsurance and 75% of several common cost-sharing items, with you paying the remaining 25%until you hit the plan’s annual out-of-pocket limit.

Plan L also includes an annual out-of-pocket limitand that’s the headline feature we’ll unpack next.

The two buckets of Plan L costs

1) Your monthly premium (the “membership fee”)

This is what you pay the insurance company every month to keep Plan L active. Premiums vary a lot by:

• Where you live (ZIP code/state rating rules)
• Age and how the company prices policies (community-rated, issue-age, or attained-age)
• Tobacco status
• Household discounts (some carriers discount for spouses/household members)
• Medical underwriting (if you apply outside protected enrollment windows)
• Company pricing strategy (two Plan L policies can be identical in benefits but very different in price)

Plan L is often marketed as “lower premium than the big hitters,” and that can be trueespecially compared with Plan Gbut there is no universal “average premium” that’s accurate nationwide. The only honest answer is: premium depends on your specific profile and where you live.

2) Your cost-sharing when you use care (the “per-visit math”)

With Plan L, you generally pay some share of many Medicare cost-sharing amounts until you hit the plan’s annual limit. This is where people either save money… or get annoyed at the register.

The Plan L out-of-pocket limit: the feature that changes the whole value equation

Original Medicare (Part A and Part B) doesn’t include a single annual out-of-pocket maximum like many employer plans do. That’s why Plans K and L stand out: they add a yearly “stop-loss” for certain Medicare-covered costs.

What is the Plan L out-of-pocket limit in 2026?

For calendar year 2026, the annual out-of-pocket limit for Medigap Plan L is $4,000.

What happens after you hit it?

After you meet:

• your Plan L out-of-pocket yearly limit, and
• your Part B annual deductible (since Plan L doesn’t pay it),

then Plan L pays 100% of covered services for the rest of the calendar year.

What the out-of-pocket limit does NOT include

This is where expectations go to die (politely, with paperwork):

• Premiums don’t count. Not your Medigap premium, not your Part B premium.
• Prescription drugs aren’t covered by Medigap at allPart D is separate.
• Services Medicare doesn’t cover (many dental/vision/hearing items, most long-term custodial care) won’t count because Medigap is built around Medicare-approved services.
• Part B excess charges can be a wildcard: Plan L doesn’t cover them, and if you see providers who don’t accept assignment, you can be billed above the Medicare-approved amount (up to legal limits). That’s one reason Plan L shoppers often prioritize providers who accept assignment.

Plan L cost-sharing examples with real 2026 numbers

Let’s make this concrete using 2026 Medicare cost-sharing amounts and simple scenarios.

Example 1: A $200 Part B office visit

Assume you’ve already met your Part B deductible for the year. Under Part B, Medicare generally pays 80% of the approved amount and you owe 20% coinsurance.

• Medicare pays 80% of $200 = $160
• Coinsurance is 20% of $200 = $40
• Plan L pays 75% of that $40 = $30
• You pay the remaining 25% of $40 = $10

Translation: With Plan L, many Part B services effectively leave you paying about 5% of the Medicare-approved amount (after the deductible), because you’re paying 25% of the 20% coinsurance.

Example 2: One inpatient hospital admission (Part A deductible)

In 2026, the Part A inpatient hospital deductible is $1,736 per benefit period. Plan L covers 75% of the Part A deductible.

• Part A deductible: $1,736
• Plan L pays 75%: $1,302
• You pay 25%: $434

Notice something funny? Your share ($434) is the same number as the 2026 daily hospital coinsurance for days 61–90. Medicare doesn’t coordinate its numbers to amuse us, but we’ll take the small joys.

Example 3: A long hospital stay (coinsurance days 61–90)

In 2026, the daily hospital coinsurance for days 61–90 is $434 per day. Plan L covers 100% of Part A coinsurance (that’s one of the “full coverage” pieces).

If you stayed 10 days in that 61–90 window, your Part A coinsurance would be 10 × $434 = $4,340. Under Plan L, that coinsurance portion would be $0 out of your pocket (you may still owe your portion of the deductible as shown above).

Example 4: Skilled Nursing Facility (SNF) coinsurance days 21–100

In 2026, SNF coinsurance for days 21–100 is $217 per day. Plan L pays 75%, you pay 25%.

• Your daily share: 25% × $217 = $54.25 per day
• If you had 30 coinurance days: 30 × $54.25 = $1,627.50

This is the kind of scenario where the Plan L out-of-pocket limit can matterbecause rehab stays can stack up quickly.

Why Plan L premiums vary so much (and why “my neighbor pays…” is not helpful)

Medicare itself standardizes benefits by letter, but it does not standardize prices. Insurers can price the same standardized plan differently. A few big drivers:

Pricing method: community-rated vs. issue-age vs. attained-age

• Community-rated: generally the same premium regardless of age (can still rise due to inflation/other factors).
• Issue-age-rated: premium is based on your age when you buy; it won’t rise just because you got older (but can rise for other reasons).
• Attained-age-rated: premium is based on your current age and tends to increase as you age.

If attained-age pricing were a birthday card, it would say: “Congrats! You’re older! Here’s your new premium.”

Underwriting (when you buy matters)

Your best shot at straightforward pricing is usually during your one-time Medigap Open Enrollment Period (the six months after you’re 65 or older and enrolled in Part B). During that window, companies generally can’t use medical underwriting to deny you or charge more due to health conditions. Outside that window, underwriting rules and guaranteed-issue protections become a much bigger deal.

Discounts and plan variants

Some companies offer household discounts, electronic payment discounts, or Medicare SELECT versions (network-based) that may lower premiums. Always confirm what’s required to keep the discount.

How to estimate your “real” annual Plan L cost

If you want a comparison that doesn’t fall apart in April, use a simple two-part estimate:

Estimated annual cost = (monthly premium × 12) + expected out-of-pocket spending (up to the Plan L limit)

Then stress-test your estimate with two “what if” years:

• Low-use year: mostly preventive care and a few office visits (your out-of-pocket might stay small; the premium is the main cost).
• High-use year: hospital stay + rehab + frequent outpatient care (out-of-pocket could rise toward the $4,000 limit, and then Plan L becomes more protective).

This is also the fair way to compare Plan L against something like Plan G or Plan N: higher premium vs. lower cost-sharing. Plan L often appeals to people who want a lower premium while still having a defined worst-case ceiling for certain Medicare-covered costs.

Shopping tips that actually help (instead of just adding tabs to your browser)

Compare apples to apples

Only compare Plan L to Plan L when comparing insurers. Benefits are standardized; price is the differentiator.

Ask questions that predict your future premium, not just today’s

• How is this policy priced (community, issue-age, attained-age)?
• How often have you raised rates on this plan in my state?
• Are there discounts, and what do I have to do to keep them?
• Is this a Medicare SELECT policy (network-based)?

Check provider habits

Because Plan L doesn’t cover Part B excess charges, many people prefer doctors who accept assignment. It reduces the chance of surprise “above-approved” bills.

Who Plan L tends to fit best (and who should think twice)

Plan L can be a strong fit if you:

• Want a lower premium than more comprehensive Medigap plans.
• Prefer the comfort of an annual out-of-pocket limit for many Medicare cost-sharing items.
• Are okay paying some costs as you go (especially Part B coinsurance and part of the Part A deductible).
• Like the predictability of “I’ll never pay more than X for covered cost-sharing this year” (after meeting Part B deductible and the Plan L limit).

Think twice if you:

• Strongly prefer “nearly everything covered” simplicity (Plan G is often chosen for that mindset).
• Regularly see providers who bill excess charges (Plan L won’t help with those).
• Want foreign travel emergency coverage included (Plan L doesn’t include it).

FAQ: fast answers on Plan L costs

Does Plan L cover the Part B deductible?

No. You pay the Part B deductible yourself. In 2026, the Part B deductible is $283.

Do my premiums count toward the $4,000 out-of-pocket limit?

No. The out-of-pocket limit is about certain Medicare cost-sharing amounts, not premiums.

Can Plan L premiums increase every year?

Yes. Even if your plan isn’t “attained-age” rated, premiums can rise due to inflation, medical trend, and company rate adjustments. Pricing method mainly determines whether age itself drives increases.

Do I still need Part D?

If you want prescription coverage, yesMedigap plans don’t include Part D drug coverage.

Conclusion: the real meaning of “Plan L costs”

Plan L costs make the most sense when you view them as a trade: lower monthly premium plus shared cost-paying (75/25), balanced by a built-in annual out-of-pocket limit for many Medicare-covered cost-sharing items. If you like the idea of paying a bit more when you use carebut not getting stuck with unlimited exposure in a bad yearPlan L can be a very rational middle path.

The smartest next step is simple: compare multiple Plan L premiums in your ZIP code, confirm the pricing method, and estimate your annual cost under both a low-use and high-use year. That gives you a decision you can feel good aboutwithout needing a PhD in acronyms.

Experiences related to Medicare Supplement Plan L Costs (common real-world scenarios)

Below are typical experiences Medicare beneficiaries report when living with Plan Lwritten as scenario-style snapshots. They’re not promises (healthcare never makes promises), but they show how Plan L costs can feel month to month.

Experience 1: “I picked Plan L because I hated the idea of no ceiling.”

A lot of people come to Plan L after realizing Original Medicare doesn’t have a single annual out-of-pocket maximum for Part A and Part B. In an average year, they might only have a few office visits and labs. They notice that after meeting the Part B deductible, many bills are small but frequentlike paying roughly $10 on a $200 office visit because Plan L picks up most of the Part B coinsurance. The emotional win is the sense that, even if something big happens later, there’s an annual cap on many cost-sharing items. The practical trade-off they feel is that Plan L isn’t a “set it and forget it” plan: you still pay your share along the way, so budgeting matters.

Experience 2: “My premium was lower than Plan G, but I had more little bills.”

This is probably the most common Plan L vibe. Beneficiaries compare Plan L to more comprehensive options and like the lower premium. Then real life happens: a specialist visit here, imaging there, a few therapy sessions. None of the bills are catastrophic, but they’re not zero either. The person who loves Plan L says, “My premium savings more than covered these small out-of-pocket costs.” The person who dislikes Plan L says, “I thought ‘supplement’ meant I wouldn’t see so many bills.” Same plan, different expectations. The difference is whether the premium savings are truly worth the extra cost-sharing in your usage pattern.

Experience 3: “The hospital deductible share surprised meuntil I did the math.”

Hospitalizations are where Plan L’s numbers get very real, very fast. In 2026, the Part A deductible is $1,736 per benefit period, and Plan L pays 75% of it. That means the beneficiary’s share is $434 for that deductible. Many people initially react with, “Wait, why am I paying anything for a hospital stay?” Then they compare it to paying the full Part A deductible without Medigap, and they realize Plan L still saved them $1,302 on that single item. If the stay extends into days 61–90, Plan L covering 100% of the Part A daily coinsurance can feel like a major reliefespecially when the math starts multiplying by days.

Experience 4: “Rehab was the year I finally understood the out-of-pocket limit.”

Skilled nursing facility coinsurance can be a turning point for Plan L users. In 2026, SNF coinsurance is $217 per day for days 21–100, and Plan L leaves you paying 25% ($54.25/day). Someone doing rehab after surgery might face several weeks of coinsurance days. At first, it feels like a slow leak$54 here, $54 thereuntil the total becomes meaningful. That’s when the Plan L out-of-pocket limit starts to feel less like a brochure bullet point and more like a real financial guardrail. People who hit the limit (plus their Part B deductible) often describe the rest of the year as noticeably calmer, because Plan L then pays 100% of covered services for the remainder of the calendar year.

Experience 5: “I learned to ask if my doctor accepts assignment.”

Plan L doesn’t cover Part B excess charges, so some beneficiaries become more intentional shoppers of healthcare, not just insurance. They ask office staff whether a provider accepts Medicare assignment, and they choose providers who doespecially for specialists. It’s not about being difficult; it’s about avoiding the kind of bill that isn’t softened by Plan L and might not help you reach your out-of-pocket limit anyway. People who build this habit early tend to feel more satisfied with Plan L, because fewer costs come as surprises.
