Does Medicare cover podiatry? The diabetic foot care exception Sioux Falls should know in 2026

Medicare will not pay to trim your toenails. It will pay for a diabetic foot exam every six months — if you know the rule exists before you need it.

Medicare will not pay a podiatrist to trim your toenails or shave down a callus — that's true whether you're 66 or 96, and it doesn't change based on how uncomfortable it's gotten. But if you have diabetes and it's damaged the nerves in your feet enough that you can't reliably feel a cut or a sore forming, Medicare has built a specific, narrow exception that covers a real foot exam twice a year. Almost nobody hears about this rule until a bill arrives that seems wrong, or until a podiatrist's office mentions it in passing. This guide walks through exactly what's covered, what isn't, the six-month rule and how it actually works, the separate shoe benefit, what it costs in 2026, and how Sioux Falls's own diabetes numbers make this more than an abstract question for a real share of Minnehaha County.

Every figure below comes from a primary source fetched this week: Medicare.gov's own foot care coverage page, CMS's National Coverage Determination on diabetic neuropathy with LOPS, Noridian (South Dakota's Medicare Part B contractor), CMS's therapeutic shoes policy article, KFF's 2026 Medicare Advantage benefit analysis, and CDC PLACES county health data. No numbers from memory.

Does Medicare cover podiatry?

Sometimes. Medicare Part B — the part of Medicare that pays for outpatient medical care — covers a podiatrist's (foot doctor's) treatment when it's for a foot injury or disease, the same way it covers any other medically necessary specialist visit, per Medicare.gov's own foot care page. Hammer toe correction, heel spur treatment, an infected ingrown toenail, a fracture — all treated the same as a visit to any other doctor, with the standard 20% coinsurance after your Part B deductible.

What Medicare almost never covers is routine foot care — the everyday maintenance most people picture when they think "podiatrist appointment." That means clipping or trimming toenails, removing corns and calluses, and other hygienic foot care, per Medicare.gov's own language. It doesn't matter if your feet genuinely need it, if you can no longer reach them, or if a podiatrist is the one doing it. Routine is routine, and Medicare draws that line by the type of service, not by how much you need it or who performs it.

Why Medicare draws the line where it does

The routine-care exclusion isn't an oversight or a cost-cutting afterthought — it's written into how Medicare has classified foot care since the earliest coverage manuals, and it comes down to one distinction: is this a medical service, or a maintenance one? Medicare was built to pay for treating disease and injury, not for personal upkeep, and routine foot care — the kind you'd otherwise pay a salon or do yourself — falls on the maintenance side of that line even when a licensed podiatrist is the one holding the clippers.

Medicare does carve out real exceptions, and they hinge on a second concept: systemic disease. If a documented condition elsewhere in your body makes ordinary foot care genuinely risky to skip — because it could trigger an infection, an ulcer, or worse — Medicare will pay for that same nail trim or callus removal as a medically necessary service instead of a routine one. CMS's own Local Coverage Determination on routine foot care lists the qualifying systemic conditions, and diabetes with complications sits at the top of a list that also includes peripheral vascular disease, ALS, chronic venous insufficiency, lymphedema tied to a specific underlying disease, arteritis of the feet, Raynaud's disease, and intractable edema from a documented cause.

Even under a systemic-condition exception, Medicare caps how often it will pay: no more than once every 60 days for most of the qualifying conditions on that list, per CMS's own Billing and Coding: Foot Care article. A claim submitted more often than that "will be denied as not reasonable and necessary," in CMS's own words. Billing staff use specific modifiers — Q7, Q8, and Q9 — tied to a clinical checklist of physical findings (documented pulses, hair growth, skin color, nail condition, and similar signs) that CMS calls Class A, B, and C findings, all defined in the Medicare Benefit Policy Manual. None of that paperwork is yours to manage — a podiatrist's billing staff handles it — but knowing it exists explains why a claim sometimes gets denied even when the visit felt obviously necessary: the specific documentation, not just the diagnosis, has to be on file.

The diabetic exception: LOPS and the six-month rule

Diabetes gets its own, more specific rule on top of the general systemic-condition exception above, and it's the one most likely to apply to a Sioux Falls reader. It centers on a condition called Loss of Protective Sensation, or LOPS — nerve damage severe enough that a person can no longer reliably feel a cut, blister, pebble in a shoe, or sore forming on their own foot. That's dangerous specifically because someone with diabetes heals slowly and fights infection less effectively, so an unnoticed wound can progress a long way before it's caught.

CMS diagnoses LOPS with a specific, standardized test: the 5.07 Semmes-Weinstein monofilament, a thin nylon filament pressed against five points on the sole of each foot. If sensation is absent at two or more of those five points on either foot, LOPS is present, per CMS's National Coverage Determination 70.2.1 decision memo. Once that diagnosis is documented, and once your doctor has ruled out other causes of the neuropathy, Medicare's rule is direct: an examination of the feet is covered no more than once every six months, as long as you haven't already seen a foot care specialist for some other reason during that stretch.

That interim catch trips up more people than the six-month window itself. Say your LOPS exam happens in January. If you twist an ankle in May and a podiatrist treats it, that visit — for a reason unrelated to the LOPS exam — becomes the new anchor point. Your next covered routine-style foot exam isn't available until six months after May, not six months after January. It's a reasonable rule once you know it (Medicare doesn't want to pay for the same category of visit twice in a stretch), but it's the kind of detail that only ever gets explained after someone's claim gets denied.

What it costs when nobody explains this

There are two separate ways this rule costs people money, and they pull in opposite directions. The first is straightforward: paying full price, out of pocket, for a routine nail trim or callus removal that felt obviously necessary but doesn't meet a coverage exception. Medicare pays $0 toward that, full stop, and the whole bill lands on you.

The second is the one worth taking seriously: skipping foot checks altogether because nobody explained that a real, no-extra-hoops Medicare benefit exists for exactly this situation. Untreated LOPS is genuinely dangerous. Per the federal government's own Healthy People 2030 tracking (HHS Office of Disease Prevention and Health Promotion), the national lower-extremity amputation rate among adults with diagnosed diabetes ran 6.2 amputations per 1,000 adults in 2019 and remained at 6.2 per 1,000 as of 2021, the most recent year tracked — against a national target of 5.5, meaning the country hasn't moved the needle in years.

A twice-a-year exam that catches a small sore before it becomes an ulcer is a genuinely different outcome than the one that ends in a hospital admission or an amputation. That's the real stake behind a benefit that sounds almost too small to matter — a foot exam — until you look at what it's designed to catch early.

On the dollar side: for a covered visit, you're on the hook for the standard Part B math — your $283 annual deductible for 2026 if you haven't met it yet from other care, then 20% coinsurance on whatever Medicare approves for that visit, per CMS's 2026 Parts A & B Premiums and Deductibles fact sheet, published November 14, 2025. If your LOPS exam is the first Part B service you use all year, the full deductible applies to it first. If you've already met the deductible from other visits — a wellness exam, a specialist appointment, a lab test — the exam is billed at just the 20% coinsurance. Either way, a Medigap Plan G supplement (covered in the next section) would bring your share of that coinsurance down to $0 once the deductible is met.

The other benefit: therapeutic shoes and inserts

Separate from the exam itself, Medicare Part B covers therapeutic shoes or inserts for people with diabetes and severe diabetes-related foot disease — a real benefit, but one with its own eligibility test and a strict once-a-year limit. Per Medicare.gov's own Therapeutic Shoes & Inserts page, you qualify if the doctor treating your diabetes certifies that you have diabetes, at least one qualifying foot condition (a history of partial or complete foot amputation, past foot ulcers, calluses that could become ulcers, nerve damage with signs of callus problems, poor circulation, or a foot deformity), and that you're under a comprehensive diabetes care plan that needs the shoes or inserts because of your diabetes.

The annual limit runs one of two ways, never both in the same calendar year, per CMS's own Policy Article A52501:

• One pair of custom-molded shoes (inserts included) plus 2 additional pairs of inserts, or
• One pair of extra-depth shoes plus 3 pairs of inserts.

The timing rules are specific enough that missing them can cost you the whole year's benefit. The physician certifying your need — and it has to be an M.D. or D.O., not a nurse practitioner or physician assistant alone — must have an in-person visit addressing your diabetes management within 6 months before the shoes are delivered, and must sign the certification statement itself within 3 months before delivery. CMS is explicit that "the certification statement is not sufficient to meet the requirement for documentation in the medical record" — the actual visit notes have to back it up, not just a signed form. Cost-sharing follows the standard Part B rule: your deductible if unmet, then 20% coinsurance on the Medicare-approved amount, per Medicare.gov.

Original Medicare vs. Medigap vs. Medicare Advantage: what actually changes

The coverage rules above — what counts as medically necessary, the every-6-month LOPS exam, the annual shoe limit — come from federal Medicare rule and apply the same way whether you're on Original Medicare or a Medicare Advantage plan. What changes between them is what you personally owe once a claim is approved.

Source: CMS — Choosing a Medigap Policy (Publication 02110) and CMS — 2026 Medicare Parts A & B Premiums and Deductibles (Fact Sheet), 2026.

Notice what a Medigap Plan G supplement does here: it doesn't create new coverage for anything Medicare already excludes — routine nail trimming is still $0 covered, Plan G or not — but for a service Medicare has already approved, like the LOPS exam, it closes the 20% coinsurance gap almost entirely. That's the whole design of Medigap in one example: it fills gaps in what Original Medicare already covers, it never expands what counts as covered in the first place.

What your Medicare Advantage plan might add, and why it's not tracked

Medicare Advantage plans are allowed to offer supplemental benefits beyond what Original Medicare covers, and some plans include a modest routine foot-care allowance as one of them. The honest answer for whether yours does: nobody can tell you without looking at your specific plan's Summary of Benefits, because — unlike vision, dental, and hearing — podiatry isn't a benefit category KFF's independent, plan-by-plan analysis tracks separately.

Source: KFF — Medicare Advantage in 2026: Premiums, Out-of-Pocket Limits, Supplemental Benefits, and Prior Authorization, 2026 plan year. Routine podiatry/foot care is not a category this analysis tracks separately — it isn't listed among the benefit types above.

That gap in the data isn't an oversight on KFF's part — it reflects how inconsistently plans structure a foot-care allowance, if they offer one at all. Minnehaha County's five standard Medicare Advantage PPOs, open to anyone with Medicare in the county for 2026, each publish their own Summary of Benefits with their own answer:

Source: CMS Medicare Advantage / Part D Landscape (PY2026) & CMS Medicare Advantage & Part D Star Ratings (2026), Minnehaha County, 2026. These are the plans open to anyone with Medicare in the county; the county also has Dual-Eligible and Institutional Special Needs Plans and Medica Cost plans with their own benefit designs — see our all-plans guide.

None of this means one of these plans is "better" for foot care than another — we don't rank plans that way, and a plan's star rating above reflects its overall CMS quality measure, not a podiatry-specific score. It means the only reliable answer is your own plan's Summary of Benefits or a phone call to member services, checked before you assume either way.

How to check your own coverage, step by step

You can work through this yourself, and most of it takes one or two phone calls:

1. Ask your primary care doctor directly whether you have documented diabetic peripheral neuropathy, and whether a monofilament test has ever been done. If it hasn't, ask for one at your next visit.
2. Get the LOPS diagnosis formally documented in your chart if the test confirms it — this is what a podiatrist's office needs on file before billing your first covered exam.
3. Track the date of your last foot exam, covered or not, so you know when the next six-month window opens — and remember that any podiatrist visit for something else resets that clock.
4. If you think you need therapeutic shoes, start the conversation with your diabetes doctor early. The 6-month prior visit and 3-month certification window mean this isn't a same-week benefit to activate.
5. Confirm your podiatrist accepts Medicare assignment before the visit — assignment is what caps your bill at the Medicare-approved amount plus your normal coinsurance, rather than a higher, unrestricted charge.
6. Pull your plan's actual Summary of Benefits (Original Medicare + Medigap, or your Medicare Advantage plan) and search it for "podiatry" or "routine foot care" — don't assume either way based on a commercial or a neighbor's plan.

How a local advisor helps

We're not a substitute for your doctor's clinical judgment about LOPS or your podiatrist's billing office — those calls belong with them. Where a local Medicare advisor is genuinely useful is the piece that's easy to lose track of: making sure your plan comparison and annual coverage review actually check whether a plan's supplemental benefits include a foot-care allowance before you re-enroll, and helping you read a Summary of Benefits that, frankly, wasn't written for easy skimming. If a claim for a covered exam gets denied anyway, that's exactly the kind of situation our claims support and appeals service exists for — someone local who has seen this specific denial before, on your side of the phone call.

What you get out of that conversation is concrete: clarity on whether your current plan adds anything beyond the federal minimum for foot care, a second pair of eyes on your Summary of Benefits before Annual Enrollment, and someone to call if a covered claim gets denied on a technicality you didn't know existed.

The Sioux Falls and Minnehaha County picture

This isn't an abstract federal rule for Minnehaha County. Per CDC PLACES 2023 county health data, 10% of Minnehaha County adults have diagnosed diabetes — a real share of the county's population sitting inside the exact coverage question this article walks through. The county carries 39,532 Medicare beneficiaries for 2026, per CMS's own county enrollment data, served by both of Sioux Falls's major health systems — Sanford Health and Avera Health — each running podiatry and diabetes-care clinics across the metro and into Brandon, Harrisburg, and Tea along the Big Sioux River.

The practical takeaway isn't that Sioux Falls has it worse than anywhere else — it's that this is a common-enough local situation that "ask about the six-month rule" belongs on the same short list as checking your drug formulary or your doctor's network before Annual Enrollment each fall. For the broader picture of how diabetes intersects with the rest of Medicare coverage locally — glucose monitors, insulin, the $2,100 Part D cap — see our Medicare and diabetes guide. For how Medicare handles equipment more broadly, including where the 20% DME coinsurance shows up elsewhere, see our durable medical equipment guide. And if Medigap is new territory, our Medicare Supplement guide walks through Plan G, Plan N, and the rest of the standardized letters in full.

What to watch in 2026 and 2027

1. Your Summary of Benefits at each Annual Enrollment (October 15–December 7, 2026) — a plan's routine foot-care allowance, where one exists, can change year to year like any other supplemental benefit.
2. Whether your LOPS diagnosis is actually documented, not just clinically obvious — undocumented conditions are the most common reason a foot-care claim gets denied on a technicality.
3. The 2027 Part B deductible and coinsurance figures, released each November — confirm the current-year number before assuming this year's $283 still applies.
4. Whether KFF or CMS begins tracking podiatry as its own Medicare Advantage benefit category — as of the 2026 analysis, it still doesn't, which keeps this a check-your-own-plan question rather than a national statistic.
5. Any interim podiatrist visit for an unrelated issue — it's the single most common way the six-month exam clock resets without anyone realizing it happened.
