Medicare Open Enrollment: Foot-Care Questions to Ask Before You Switch Plans

Every year between mid-October and early December, millions of people with Medicare sit down at the kitchen table with a stack of plan mailers and try to decide whether to stay put or switch. Most of the questions are about premiums, drug lists and doctor networks. Foot care rarely makes the list, yet for people living with diabetes, nerve changes, circulation concerns or limited mobility, the details of foot coverage can shape the next twelve months of appointments, shoes and out-of-pocket costs.

This guide is designed to help you walk into Open Enrollment with a better set of questions. It explains the key dates, what Original Medicare and Medicare Advantage generally do and do not say about foot care, and a practical checklist you can bring to a plan representative, a State Health Insurance Assistance Program counselor, or your own healthcare provider. We are a sock company, not an insurance advisor, so we stick to general information and point you to the official sources for the rules that apply to you.

Last updated: October 2026. Medicare rules, dollar amounts and plan benefits change from year to year, so confirm every figure with Medicare or your plan before making a decision.

Key Medicare Open Enrollment Dates

Medicare's own key dates fact sheet lays out the calendar. In plain terms, Open Enrollment runs from October 15 through December 7. During that window, people with Medicare can keep their current health and drug coverage or switch to a different plan for the following year, and the forms generally need to reach the plan by December 7. New coverage begins on January 1.

There is a second window many people forget. If you are enrolled in a Medicare Advantage plan, you can generally switch to a different Medicare Advantage plan or go back to Original Medicare between January 1 and March 31. Coverage from that change starts the first day of the month after the plan receives the request. Medicare also notes that people who return to Original Medicare in that window can join a separate drug plan. If you are unsure which period applies to you, the CMS Open Enrollment resources page is a good starting point, and you can call 1-800-MEDICARE for personal guidance.

If You Like Your Plan, You May Not Need to Do Anything

According to CMS, if your current plan still meets your needs and is still being offered, you do not have to act. That said, plans change their networks, formularies and benefits each year, so it is worth reading your Annual Notice of Change when it arrives. This is where foot-care changes often hide: a podiatrist who is no longer in network, a new prior authorization requirement or a reduced over-the-counter allowance can show up in the fine print.

Why Foot Care Deserves a Spot on Your Checklist

Feet carry you through nearly every part of daily life, and for some people they need more attention than average. Diabetes can affect sensation and circulation in the feet, which is why foot exams, properly fitting footwear and daily skin checks are standard parts of diabetes self-care. Arthritis, previous injuries, swelling and balance concerns can add to the picture. If any of these apply to you, the question is not only whether Medicare covers foot care but how, how often, with whom and at what cost.

Because the answers vary between Original Medicare and individual Medicare Advantage plans, and because plans can change from year to year, it pays to ask specific questions before you switch rather than after.

What Original Medicare Generally Says About Foot Care

Original Medicare is the traditional, government-run program made up of Part A (hospital) and Part B (medical). Here is a general overview, with the caveat that your individual situation, diagnosis and provider all affect what is covered.

Routine Foot Care Versus Medically Necessary Care

Original Medicare is typically understood to exclude routine foot care such as trimming nails or removing calluses when it is done for convenience or comfort, with exceptions in certain medical circumstances. Care considered medically necessary may be handled differently. The distinction is detailed and depends on documentation, so ask a podiatrist's office how they bill and what they need from you.

Therapeutic Shoes and Inserts for Diabetes

Medicare Part B includes a benefit for therapeutic shoes and inserts for people with diabetes who also meet certain foot-condition criteria. The official Medicare therapeutic shoes and inserts page describes who qualifies and what is included. In general, the doctor who manages your diabetes has to certify the need, and the shoes must come from an enrolled, qualified supplier. We walk through the details in our guide to the Medicare Therapeutic Shoe Program.

The Honest Answer on Diabetic Socks

This is the point that surprises many people: the official descriptions of the therapeutic shoe benefit focus on shoes, inserts and certain modifications. Socks are not listed. We are direct about this because we would rather you plan accurately than assume coverage that does not exist. Our article Does Medicare Cover Diabetic Socks? The Honest Answer goes into more detail. Please do not read anything on our site as saying our socks are covered by Medicare, because Original Medicare does not describe them that way.

What Medicare Advantage Plans May Add

Medicare Advantage (Part C) plans are offered by private insurers and must cover what Original Medicare covers, but they often include extra benefits that differ from plan to plan. Some of the extras that may matter to foot care include:

• Routine podiatry visits. Some plans list a number of covered visits per year. Others have none.
• Over-the-counter (OTC) allowances. A few plans give members a quarterly or yearly credit toward a catalog of health products. Whether socks are in the catalog depends entirely on the plan. We explain more in Does Medicare Advantage Cover Over-the-Counter Sock Purchases?
• Network rules. Many plans use HMO or PPO networks, so a podiatrist you already see may or may not be included.
• Referrals and prior authorization. Some plans require a referral from a primary care doctor before you can see a specialist.
• Supplier requirements. If you need therapeutic shoes, the plan may require you to use particular suppliers.

Because these extras are optional and vary widely, you should treat the plan's own documents, not a general article like this one, as the source of truth.

Twelve Foot-Care Questions to Ask Before You Switch

Print this list, write the answers beside each question and keep it with your plan comparison. If you are on the phone with a plan representative, ask them to point you to the page in the plan documents where each answer appears.

1. Is my podiatrist in network? Ask for the provider's name and confirm it on the plan's directory, and call the office to double-check.
2. How many routine foot-care visits are covered per year, and what is the copay? Some plans list this under supplemental benefits.
3. Do I need a referral or prior authorization to see a podiatrist?
4. How does the plan handle therapeutic shoes and inserts? Ask which suppliers are in network and whether there are limits beyond Original Medicare's.
5. Is there an OTC allowance, and what does the catalog include? Ask whether it lists diabetic or comfort socks, and whether the allowance resets monthly, quarterly or yearly.
6. Can I use the OTC allowance at a retailer or only through the plan's catalog?
7. What are my costs for diabetes supplies and services? Ask about coverage for glucose testing supplies and diabetes self-management training, since these often go hand in hand with foot care.
8. Which specialists do I need a referral for? This might include vascular, orthopedic or wound-care specialists if you ever need them.
9. What happens if I need care out of area or while traveling?
10. What is my maximum out-of-pocket cost for the year? A podiatry visit may seem small, but costs from several services can add up.
11. Are there any changes to foot-related benefits in the Annual Notice of Change? Compare this year's notice to the previous one.
12. Who can I call if a claim is denied? Knowing the appeals process in advance saves stress later.

Where Socks Fit Into the Picture

Whatever plan you choose, socks remain a day-to-day expense for most people. The good news is that the features that matter most are not especially expensive. For people managing diabetes or sensitive feet, healthcare professionals commonly recommend socks that are soft, free of bulky seams, moisture-managing and not tight around the leg. Those are the characteristics of what are often called non-binding or diabetic socks. If you want to understand the category, our overview What Are Non-Binding Diabetic Socks? explains the design in detail.

You can browse the full range in our diabetic socks collection. Examples include the Unisex Cotton Diabetic Crew Socks, the Bamboo Diabetic Crew Socks for Women, the Men's Lightweight Bamboo Diabetic Ankle Socks and the Women's Comfortable Diabetic Bamboo Ankle Socks for Swollen Legs. These are products you would buy yourself rather than expect your plan to pay for. If you have an HSA, FSA or an OTC card, check with the administrator about what is eligible, because we cannot tell you that our socks qualify under your specific plan.

Budgeting for Foot Care Outside of Coverage

Even a generous plan leaves some foot-related costs on your side. A little planning helps.

• Make a yearly foot-care list. Include podiatry visits, shoes, inserts and socks, then compare it to what each plan lists.
• Buy socks in multi-packs. Pairs wear at different rates, and rotating them extends their life.
• Replace socks when they stop doing their job. Thin heels, stretched-out tops or hardened fibers are signs it is time.
• Ask your provider what they recommend for your feet. A short appointment can save you from buying products you do not need.

Who Can Help You Compare Plans

You do not have to do this alone. Medicare's official line at 1-800-MEDICARE and the Medicare.gov plan finder are the primary tools. Your State Health Insurance Assistance Program (SHIP) offers free, unbiased counseling in every state. Pharmacists, social workers at your clinic and family members can also help you read plan documents. Be cautious of unsolicited calls or mailers that pressure you to switch quickly. If someone asks for your Medicare number out of the blue, hang up and call the official number yourself.

Bring These to Your Appointment or Call

• Your current plan card and Annual Notice of Change
• A list of your doctors, including your podiatrist, with phone numbers
• A list of your medications and diabetes supplies
• Your foot-care questions, written down
• A notebook or printout of the checklist above

How Foot Health Fits Into Everyday Routines

Insurance paperwork can feel far removed from the simple habit of looking at your feet each day. Still, the two are connected. If you live with diabetes or reduced sensation, examining your feet every day for cuts, blisters, color changes or swelling is a basic part of self-care, and a provider can show you how. Our guide to a daily diabetic foot check in 60 seconds offers a quick routine. Many people find that the better they understand their daily foot needs, the clearer their plan questions become.

A Simple Decision Framework

When the plan comparison starts to feel overwhelming, break it into three steps.

1. List your must-haves. These are the providers, services and supplies you cannot do without. A podiatrist you trust is often at the top of the list for people with foot concerns.
2. Compare total yearly cost, not just the premium. A lower monthly premium can be offset by higher copays and a lower allowance.
3. Check the details in writing. Anything a representative says on the phone should match the plan documents.

Remember that you can usually revisit your choice. If you are in a Medicare Advantage plan and it turns out to be a poor fit, the January 1 to March 31 window described above may give you a second chance, subject to the rules in effect for you.

Final Thoughts

Medicare Open Enrollment is a once-a-year opportunity to make sure your coverage fits your life. For people who count on regular foot care, a few well-chosen questions can reveal differences between plans that a brochure's headline benefits do not. Check podiatry access, ask how therapeutic shoes and inserts are handled, find out whether an OTC allowance exists and what it includes, and be realistic about what you will pay for yourself, socks included. When in doubt, call 1-800-MEDICARE, contact your local SHIP counselor and talk with your healthcare provider about what your feet need in the year ahead.
