The Short Answer: Medigap Covers What Medicare Approves
Medigap doesn’t decide whether your speech therapy or occupational therapy is covered. Medicare does. Your Medigap plan then steps in and pays its share of whatever Medicare approves. That’s the whole relationship, and once you understand it, everything else makes sense.
Here’s the thing. A lot of people buy a Medigap plan thinking it works like a second insurance policy that has its own coverage rules. It doesn’t. Medigap is a cost-sharing tool built on top of Original Medicare. If Medicare Part B says yes to your speech therapy, your Medigap plan picks up costs. If Medicare says no, Medigap sits on the sidelines no matter what plan you have.
So the real question isn’t whether Medigap covers therapy. It’s whether Medicare covers your specific therapy situation, and then what Medigap leaves you paying out of pocket. Both of those questions have real dollar implications, and I’ll walk you through both.
How Medicare Part B Handles Speech and Occupational Therapy
Medicare Part B covers outpatient speech therapy and occupational therapy when a doctor orders them and when the services are considered medically necessary. That phrase “medically necessary” is doing a lot of heavy lifting, and I want to be direct with you about what it means in practice.
Medicare won’t pay for speech therapy just because your voice has gotten softer with age, or occupational therapy just because your balance isn’t what it used to be. There has to be a specific medical reason, usually tied to a diagnosis. Stroke recovery, Parkinson’s disease, a traumatic brain injury, dysphagia (trouble swallowing), or a surgery that affected your function, those are the kinds of conditions that typically qualify.
There’s also the question of “maintenance therapy” versus “active improvement.” For years, Medicare had an unofficial rule that once you stopped showing measurable progress, your therapy would get cut off. That changed after a 2013 court settlement called the Jimmo v. Sebelius case. Today, Medicare is supposed to cover therapy that helps you maintain your current level of function, not just therapy that improves it. In my experience, though, a lot of providers and even some Medicare contractors still act like that old rule is in force. If your therapy gets denied for lack of progress, it’s worth pushing back.
When Part B does approve your therapy, you’re responsible for 20% of the Medicare-approved amount after you’ve met the annual Part B deductible. The 2026 Part B deductible is $257. Once you’ve hit that, you owe 20% of each approved service with no cap on how high that 20% can climb if you’re getting intensive therapy over many months.
What Medigap Actually Pays (Plan by Plan)
Once Medicare approves your therapy and processes the claim, your Medigap plan pays its portion. The amount depends on which plan you have. Not all Medigap plans cover the same costs.
The table below shows how the most common Medigap plans handle the costs you’d owe for outpatient speech or occupational therapy under Part B.
| Medigap Plan | Part B Deductible ($257 in 2026) | Part B Coinsurance (20%) | Your Out-of-Pocket for Approved Therapy |
|---|---|---|---|
| Plan G | You pay | Medigap pays | $257/year, then $0 |
| Plan N | You pay | Medigap pays (with copays up to $20 per visit) | $257/year, then up to $20 per therapy visit |
| Plan F (pre-2020 enrollees only) | Medigap pays | Medigap pays | $0 |
| Plan K | You pay 50% | You pay 50% | Significant costs until out-of-pocket limit |
| Plan L | You pay 25% | You pay 25% | Moderate costs until out-of-pocket limit |
If you’re on Plan G, which I think is the right choice for most people who became Medicare-eligible after January 1, 2020, your exposure for approved outpatient therapy is just that $257 Part B deductible each year. After that, you pay nothing for the 20% coinsurance. If you’re getting three therapy sessions a week for stroke recovery, that protection is genuinely significant. A full year of regular occupational therapy can easily run $10,000 or more in total charges. Your 20% would be $2,000 or more. Plan G absorbs all of it after the deductible.
Plan N is cheaper monthly, typically $30 to $60 less per month than Plan G at age 65 depending on your state and insurer, but those per-visit copays add up quickly if you’re going to therapy regularly.
The Mistake I See People Make All the Time
People assume that because they have Medigap, their therapy is covered, and then they’re blindsided when Medicare denies the claim.
I’ve seen this happen a lot with occupational therapy in particular. Someone slows down, has trouble managing daily tasks, and their family pushes them to get OT. They get a referral, start sessions, and months later a bill arrives because Medicare denied the claim. The provider may not have documented medical necessity clearly enough. The orders may have been vague. Or the therapy genuinely didn’t meet Medicare’s criteria.
When Medicare denies, Medigap won’t pay. You can end up owing the full cost of every session. That can be hundreds or even thousands of dollars depending on how long you received care before the denial.
There are two things you can do to protect yourself. First, make sure your doctor documents the specific medical reason for your therapy clearly in writing before you start. “Patient has difficulty with daily tasks” isn’t enough. “Patient presents with significant upper extremity weakness following right hemispheric stroke affecting ability to dress, prepare meals, and manage medications” is the kind of language that gets claims approved. Second, ask the provider upfront whether they participate in Medicare and whether they believe your situation meets medical necessity. A good provider will tell you honestly.
Also, if Medicare does deny a claim, appeal it. The appeals process has multiple levels, and beneficiaries win a meaningful number of them. Don’t just pay the bill because the initial answer was no.
Inpatient Therapy Is Different: Part A Kicks In Instead
If you’re receiving speech or occupational therapy as a hospital inpatient or in a skilled nursing facility, Part B isn’t involved. Part A is. And the cost structure is completely different.
The 2026 Part A deductible is $1,676 per benefit period. That covers your first 60 days of inpatient care including any therapy you receive during that stay. If you’re in a skilled nursing facility after a qualifying hospital stay, Part A covers the first 20 days in full, then you owe a daily coinsurance of $209.50 per day in 2026 for days 21 through 100.
A good Medigap plan covers those costs too. Plan G covers the Part A deductible and the skilled nursing facility daily coinsurance. So if a 67-year-old in Ohio has a stroke, spends time in a rehab facility doing speech therapy and occupational therapy for 45 days, their Plan G covers the Part A deductible and the daily coinsurance for days 21 through 45. That’s significant protection.
The distinction between inpatient and outpatient therapy isn’t always obvious to patients. Whether you’re admitted as an inpatient or treated as an outpatient observation patient affects which part of Medicare pays. Observation status, where you’re in the hospital but technically outpatient, is a separate mess that deserves its own article.
Bottom Line
If you have Plan G and Medicare approves your speech or occupational therapy, you’re well protected. You pay the $257 Part B deductible in 2026, and after that your costs are zero. The bigger risk isn’t your Medigap plan, it’s whether Medicare approves the claim in the first place, and that depends entirely on how well your medical team documents necessity. Make sure the paperwork is solid before you start treatment, and don’t accept a denial without appealing.
Frequently Asked Questions
Does Medigap cover speech therapy after a stroke?
Yes, if Medicare Part B approves it, which it almost certainly will for stroke-related speech therapy given that a clear medical diagnosis and need exist. Stroke is exactly the kind of diagnosis Medicare is designed to cover. With Plan G, you’d pay the annual Part B deductible and nothing else for approved outpatient sessions.
What if my doctor says I need occupational therapy but Medicare denies it?
You have the right to appeal. Start with a Redetermination request within 120 days of the denial. If that fails, you can escalate through four additional levels including an Administrative Law Judge hearing and federal court. Many denials at the initial level get overturned on appeal, especially when a physician provides stronger documentation of medical necessity.
Does Medigap cover therapy from a private therapist who doesn’t accept Medicare?
No. Medigap only covers services that go through Medicare’s billing system. If your therapist doesn’t accept Medicare assignment and doesn’t bill Medicare at all, there’s no Medicare claim for Medigap to pay against. You’d be paying fully out of pocket. This is a case where it genuinely matters whether your provider participates in Medicare.
Is there a limit on how many therapy sessions Medicare covers per year?
There’s no hard cap on the number of sessions, but there is a therapy threshold. In 2026, once your outpatient therapy costs reach $2,330 for physical therapy and speech-language pathology combined, or $2,330 for occupational therapy, Medicare requires a targeted medical review to confirm continued medical necessity. This doesn’t mean coverage stops, it just means additional scrutiny. If your care is well documented, it shouldn’t be a problem.
