    Confirm You Are Eligible for the Indian Special Enrollment Period

    ~51s
    To use the special protections, you need to prove that you are an American Indian or Alaska Native who is eligible for IHS services. Acceptable proof includes a tribal enrollment card from a federally recognized tribe, a Certificate of Degree of Indian Blood (CDIB), or a letter from your tribe or IHS confirming eligibility. Make a clear photo of the front and back of your enrollment card with your phone, save it to a folder on your computer, and email a copy to yourself so you always have it. When you call an insurance company, mention up front that you are eligible for IHS and want to use the Indian Special Enrollment Period. This signals to the agent that they need to follow specific rules rather than the regular Medicare process.

    Quick Tip

    Ask your tribe's enrollment office for an official eligibility letter on tribal letterhead. Insurance companies sometimes ask for this when an enrollment card is older than ten years.

    2

    Open the Medicare Plan Finder and Enter Your Information

    ~43s
    Visit medicare.gov in a web browser. Click Find Plans on the home page. Enter your zip code and check the box that asks whether you receive financial help. Add the prescriptions you take regularly, including the dosage and how often you fill them. Adding accurate prescription information is important because the tool calculates the yearly cost of each plan based on those drugs. The site shows a list of Medicare Advantage plans available in your county. Each card lists the monthly premium, the maximum out-of-pocket limit, the star rating, and a Total Yearly Cost estimate that combines premiums, copays, and drug costs.

    Warning

    If you live in a rural area, the plan list may be short. Do not pick the cheapest plan without checking IHS coverage. The cheapest plan often has the most narrow network.

    3

    Call Each Top Plan and Ask About IHS Coverage

    ~50s
    Pick three plans from the Plan Finder that look promising and call the customer service number listed on the plan card. Ask three questions and write down the answers word for word. First, is the Indian Health Service clinic at this address considered in-network or out-of-network? Second, will I be billed any copays, coinsurance, or deductibles when I see an IHS provider? Third, how does the plan handle billing for an emergency room visit at a non-IHS hospital when I am referred by IHS? Federal law requires plans to waive cost-sharing for IHS-eligible members, but not every front-line agent knows this. If the agent is unsure, ask to be transferred to a supervisor or to the Medicare compliance team. Save the call reference number that the agent provides.

    Quick Tip

    Record the date and the name of every person you speak with. If a billing problem comes up later, having this log makes appeals much faster.

    Verify the Plan's Pharmacy Network Includes IHS Pharmacies

    ~50s
    Most IHS and tribal clinics include a pharmacy that fills prescriptions at no cost to eligible members. To keep using that pharmacy under a Medicare Advantage plan, the IHS pharmacy must be in the plan's network. Ask the plan to confirm in writing that the IHS pharmacy at your home clinic is a network pharmacy. Many plans now include 340B pharmacies, which is the federal program IHS uses, but not all of them. If the IHS pharmacy is not in the network, ask whether the plan offers a mail-order pharmacy that is covered. Compare the cost of refilling through IHS at no charge with the cost of refilling through a non-IHS network pharmacy. For many elders, sticking with IHS for routine medicines is the simplest and least expensive path.

    Warning

    If you switch plans mid-year, your IHS pharmacy may need to rebill prescriptions filled before the switch. Tell the IHS pharmacist about the change on your next visit.

    5

    Enroll Using the Indian Special Enrollment Period

    ~45s
    Once you pick a plan, you can enroll any month of the year as a Native beneficiary. Go back to medicare.gov, click Enroll on the plan you chose, and follow the prompts. When the site asks why you are enrolling outside the regular open enrollment window, choose I am an American Indian or Alaska Native. The system asks for a date and the system marks your enrollment as a Special Enrollment Period for Indians. The plan starts the first day of the next month. You can also enroll by calling 1-800-MEDICARE (1-800-633-4227) and asking the agent to apply the Indian SEP. Keep the confirmation letter that arrives in the mail within ten days.

    Quick Tip

    Use the same special enrollment period to switch back to Original Medicare if the plan is not working out. You are never locked in for the year.

    6

    Handle Bills and Appeal Wrongful Denials

    ~53s
    If you ever receive a bill from your Medicare Advantage plan for a copay at an IHS clinic, do not pay it. Instead, call the plan and tell them that as an IHS-eligible member, you are protected from cost-sharing under 42 U.S.C. 1395eee. Most agents will reverse the charge once they review the rule. If the plan refuses, file an appeal in writing within 60 days of the bill date. The appeal form is in the plan handbook or available by calling customer service. Send your appeal certified mail and keep a copy. You can also contact the State Health Insurance Help Program (SHIP) by calling 1-877-839-2675 for free one-on-one help with appeals. SHIP counselors handle Medicare cases at no charge and many have specific training for tribal communities.

    Warning

    Bills that go unpaid for 90 days can be sent to collections. Even if the bill is wrong, write a letter that says you are disputing the charge and send it to the plan within 30 days to protect your credit.

    Medicare Advantage is a way to receive your Medicare benefits through a private insurance company instead of the original Medicare program run by the federal government. Plans usually bundle hospital coverage, doctor visits, prescription drugs, and sometimes dental, vision, and hearing into a single package with a low monthly premium. For Native American elders, Medicare Advantage can work very well when the plan plays nicely with the Indian Health Service (IHS) and tribal clinics. When it does not, the result is denied claims, surprise bills, and unnecessary stress.

    Federal law gives Native Medicare beneficiaries some special protections. If you are eligible for IHS, you cannot be charged plan cost-sharing such as copays, coinsurance, or deductibles when you see an IHS or tribal health provider. You can also enroll in or change Medicare Advantage plans every month, while the rest of the country only gets to change once a year during open enrollment. This is called the Special Enrollment Period for Indians and is one of the most useful tools available to Native elders.

    Not every Medicare Advantage plan understands these rules well. Some plans automatically pay IHS claims, while others reject them at first and require an appeal. Some plans include all IHS clinics as in-network, while others classify them as out-of-network and pay less. The best plans for Native elders treat IHS as a fully covered provider, waive cost-sharing without paperwork, and refund any copays paid in error.

    This guide explains how to compare plans using medicare.gov, what questions to ask the insurance company before enrolling, how to use the monthly special enrollment period, and what to do if a plan denies a claim that should have been paid. Take your time with the choice because switching plans is free but each switch creates paperwork for the IHS clinic. Working with a tribal benefits coordinator or a State Health Insurance Help Program (SHIP) counselor is a smart move.
