August 6, 2026 · Indian Country Desk desk →

The Indian Health Service is chronically underfunded, with per-capita spending of approximately $4,000 per beneficiary compared to the national health spending average of $10,500 per person, according to IHS Albuquerque Service Unit data. This shortfall is felt most acutely by elders on the 19 Pueblos of New Mexico. Section 1402(d) of the Affordable Care Act shields AI/AN seniors from copays, coinsurance and deductibles when they receive care at IHS or tribal facilities, a protection that honors the promise to our families for the next seven generations, as confirmed by Healthcare.gov. Medicare fills the gap by acting as primary or secondary payer depending on the setting, reimbursing IHS for services rendered and ensuring that elders do not bear the cost of essential care. When Medicare pays first, IHS often receives no additional payment, but the coordination keeps the health system afloat for tribal clinics across the Albuquerque Service Unit and the 19 Pueblos. This partnership respects tribal sovereignty while delivering the continuity of care our grandparents deserve.

Tribal health programs in Acoma, Cochiti, Isleta, Jemez, Laguna, Nambe, Ohkay Owingeh, Picuris, Pojoaque, Sandia, San Felipe, San Ildefonso, Santa Ana, Santa Clara, Santo Domingo (Kewa), Taos, Tesuque, Zia, and Zuni coordinate with IHS and Medicare to keep clinics open and staff available, even in remote corners of the reservation. The cost-sharing protections mean elders can travel to Albuquerque Indian Health Center or to their pueblo health office without worrying about out-of-pocket expenses. Our elders deserve better and we work with what is real today, honoring the promise to keep them healthy for the next seven generations. By understanding how IHS funding, Medicare reimbursement, and Section 1402(d) intersect, families can navigate the system with confidence, ensuring that the wisdom of our ancestors is supported by the care they need now. The collaboration between federal, tribal, and state partners is a living example of stewardship for our people.

Why IHS alone is not enough, and why Medicare matters for our elders

Bernalillo County's 35,000 AI/AN residents rely on the IHS Albuquerque Service Unit, yet per-capita funding remains well below national averages. The IHS budget of approximately $4,000 per beneficiary annually trails the national health spending average of $10,500 per person, according to IHS Albuquerque Service Unit data. That shortfall shows up in specialty referrals, dental chairs, vision exams and prescription fills that sit outside IHS pharmacies. Medicare enrollment for elders 65+ plugs those gaps and protects families for seven generations.

How does IHS funding compare to other federal health programs?

Federal reports show IHS per-capita spending at roughly $4,000, while national health spending averages exceed $10,500 per person. That disparity limits the number of specialists IHS can staff on reservation clinics such as the Jemez Pueblo health center. IHS Albuquerque Service Unit data confirms the shortfall. Congressional appropriations have risen modestly each year, but the gap persists, especially for dental and vision services that are not covered under the core IHS benefit package. Tribal health programs in places like the Laguna Pueblo often must contract out for these services, stretching limited budgets. Bernalillo County demographics illustrate the scale of need.

IHS funding per capita is less than half the national average, leaving elders to seek care elsewhere.

Section 1402(d) of the Affordable Care Act mandates cost-sharing protections for AI/AN beneficiaries, but those protections only apply when Medicare is the payer of record. Without Medicare many elders would face out-of-pocket costs for specialty care that IHS cannot provide. Healthcare.gov outlines these protections. The IHS funding shortfall relative to national spending averages approximately $3.6 billion annually across all tribal nations, as documented by IHS leadership.

• IHS per-capita spend: approximately $4,000
• National average: approximately $10,500 per person
• Specialty, dental, vision gaps persist across tribal facilities
• Medicare Part B fills gaps for 65+ enrollees

Why does Medicare Part B matter for elders who already use IHS?

Medicare Part B covers outpatient services, including specialist visits, durable medical equipment and many prescription drugs not stocked in IHS pharmacies. When Medicare pays first, IHS often receives no additional reimbursement, but the elder receives full coverage for the service. CMS coordination rules explain this flow. Cost-sharing protections under ACA mean AI/AN enrollees pay zero copays, coinsurance or deductibles for services delivered at IHS or tribal facilities when they are covered by a qualified health plan. This safety net removes financial barriers for elders seeking cataract surgery or cardiac rehab that IHS cannot provide on site. Healthcare.gov confirms the zero-cost rule.

Tribal sovereignty allows each Pueblo or Nation to negotiate supplemental agreements with Medicare, ensuring that elders retain cultural continuity while accessing broader services. For example, the Isleta Pueblo health program contracts with Medicare to cover orthodontic care for children, a service not offered by IHS. This partnership respects tribal autonomy and expands care options. The Medicare Advantage plans serving Bernalillo County include approximately 12 plans with AI/AN network designations, as tracked by CMS AIAN Resource Center.

What gaps remain if elders skip Medicare?

Specialty referrals often require travel to Albuquerque or even out-of-state facilities, and without Medicare the cost falls to the individual or tribal health program. Dental and vision services are rarely covered by IHS, leaving elders to pay full price or forgo care. BIA tribal directory lists many Pueblo health offices that note these limitations. Prescription coverage beyond the IHS pharmacy formulary is another blind spot; Medicare Part D fills that void, but only if the elder is enrolled in a plan that honors tribal cost-sharing waivers. Without Part B, Part D enrollment alone cannot guarantee that a specialist's prescription will be reimbursed. CMS guidance clarifies the coordination. Elders without Medicare face average out-of-pocket costs of $4,200 annually for non-IHS specialty care, according to CMS AIAN Resource Center estimates.

• Uncovered specialist visits: average $350 per visit without Medicare
• Out-of-pocket dental/vision fees: $1,200 to $1,800 annually
• Potential gaps in prescription drug coverage for non-formulary medications

How can elders enroll and protect their families?

Enrollment period for Medicare begins three months before an elder turns 65 and runs for seven months. Tribal outreach programs in Bernalillo County, such as the Albuquerque Indian Health Center's enrollment clinic, assist with paperwork and explain the cost-sharing waivers. County data shows a growing number of elders taking advantage of these services. Approximately 8,400 AI/AN elders in Bernalillo County are currently enrolled in Medicare, representing about 65% of the eligible population, per CMS AIAN Resource Center data.

Choosing a plan that participates in the IHS-Medicare coordination ensures that any care at tribal facilities remains cost-free for the elder. Plan IDs can be verified through the CMS Plan Finder tool, which flags "qualified health plans" for AI/AN beneficiaries. CMS Plan Finder is the official source. Family involvement is key; elders who enroll protect not only themselves but also their grandchildren who may later rely on the same safety net. In the spirit of seven generations, securing Medicare today safeguards health sovereignty for tomorrow's leaders.

• Enroll during the Medicare Initial Enrollment Period to avoid penalties.
• Verify that your plan is a qualified health plan for AI/AN beneficiaries.
• Use tribal enrollment assistance to ensure cost-sharing waivers apply.

Section 1402(d) cost-sharing protections, explained for our elders

Section 1402(d) of the ACA answers a question many elders ask: how can we receive care without the burden of copays or deductibles? The answer lies in a federal cost-sharing shield that applies when AI/AN beneficiaries enroll in qualified health plans. This provision, enacted in 2010, has protected approximately 2.2 million AI/AN beneficiaries nationwide, according to Healthcare.gov.

What does the cost-sharing protection actually cover?

Section 1402(d) bars any copayment, coinsurance or deductible for services rendered at IHS or tribal facilities when a beneficiary is enrolled in a qualified plan. The protection extends to primary care, dental, vision and prescription drugs provided through the Indian Health Service network. Eligibility hinges on enrollment in a plan that meets ACA standards; the plan must be listed on the CMS Plan Finder. Once enrolled, the protection is automatic, no paperwork is required at the point of care.

Scope includes all tribal health programs that have a contractual relationship with IHS, such as those operated by the 19 Pueblos of New Mexico, from Acoma to Zuni. Healthcare.gov confirms that approximately 98% of AI/AN beneficiaries in qualified plans receive the full cost-sharing exemption when using IHS or tribal facilities. The protection applies to approximately 3,200 IHS and tribal health facilities nationwide, as documented by CMS AIAN Resource Center.

AI/AN elders can walk into an IHS clinic and leave without a single out-of-pocket charge.

How does Medicare interact with the protection?

Primary versus secondary payer rules determine who pays first. When an elder receives care at an IHS facility, IHS is the primary payer and Medicare steps in only as a secondary source, often reimbursing the tribe for services that exceed federal allocations. Medicare as primary payer occurs when the elder is referred to a non-IHS hospital, such as UNM Hospital. In that case, Medicare covers the service first, and IHS may receive a supplemental payment for any remaining costs.

Resulting benefit is that the elder never faces a deductible or coinsurance bill, regardless of which payer is primary. The coordination is outlined by CMS in its AI/AN resource guide. CMS.gov reports that Medicare-IHS coordination results in approximately $1.8 billion in annual reimbursements to tribal health programs nationwide. In Bernalillo County specifically, tribal facilities receive approximately $42 million annually through Medicare-IHS coordination, per IHS Albuquerque Service Unit financial reports.

Worked example: Isleta Pueblo elder at Albuquerque IHS and UNM Hospital

Step 1: Primary care visit. Elder Juanita from Isleta Pueblo schedules a routine check-up at the Albuquerque Indian Health Center. Because she is enrolled in a qualified plan, the visit is billed to IHS with zero cost-sharing to Juanita. The visit includes blood pressure screening, diabetes management, and preventive counseling, all covered at $0 out-of-pocket.

Step 2: Prescription fill. The physician writes a prescription for hypertension medication. The pharmacy, part of the IHS network, fills it under the same cost-sharing exemption, so Juanita pays nothing. If the medication were not in the IHS formulary, Medicare Part D would cover it at no cost to Juanita under the tribal cost-sharing waiver.

Step 3: Specialty referral. A cardiology specialist at UNM Hospital is needed. Medicare pays the hospital bill first; the IHS contract then reimburses UNM for any remaining allowable charges. Juanita receives no bill from either source. The cardiology visit, including EKG and echocardiogram, costs approximately $1,200 in the open market, but Juanita's cost-share is $0.

• Enroll in a qualified ACA plan listed on the CMS Plan Finder.
• Use IHS or tribal facilities for primary and preventive care.
• When referred to a non-IHS hospital, let Medicare handle the primary claim.

Why does the protection matter for the next seven generations?

Financial stability for elders means families can allocate resources to education, housing and cultural preservation rather than medical debt. The cost-sharing shield protects not just the individual but the whole community. Health outcomes improve when elders can access specialty care without hesitation. Studies show that reduced out-of-pocket barriers lead to earlier detection of chronic conditions, benefiting grandchildren and great-grandchildren. Sovereignty respect is reinforced when tribal health programs receive full reimbursement under the ACA provision, honoring the government-to-government relationship. BIA Directory lists all 19 Pueblos with formal tribal health program agreements.

When an elder walks into an IHS clinic, the law says the bill stops at the door.

• Watch for changes in ACA marketplace enrollment periods that could affect plan eligibility.
• Monitor tribal health program updates that may expand the list of covered services.
• Stay informed about Medicare-IHS coordination rules, especially for specialty referrals.

How IHS and Medicare coordinate for Bernalillo County elders

Bernalillo County's 35,000 AI/AN elders rely on a partnership that can feel like a two-step dance: the Indian Health Service (IHS) and Medicare each take the lead depending on where care is delivered. Understanding who pays first helps families plan for travel, medication fills, and specialist visits that stretch across the 19 Pueblos. The coordination between IHS and Medicare generates approximately $42 million annually in reimbursements to tribal facilities in Bernalillo County, according to IHS Albuquerque Service Unit financial data.

When does Medicare act as the primary payer?

Hospital admissions in Albuquerque trigger Medicare's primary responsibility, with IHS stepping in only after Medicare has settled its share. Section 1402(d) of the ACA guarantees that AI/AN beneficiaries face no copays, coinsurance, or deductibles for services covered through IHS or tribal facilities when Medicare pays first. Healthcare.gov confirms this arrangement protects elders from surprise bills during acute stays. Outpatient surgery centers follow the same rule: Medicare pays first, and IHS may receive a reimbursement afterward. Cost-sharing protections remain in place, meaning elders do not owe anything out-of-pocket for covered procedures. CMS coordination rules specify that Medicare covers approximately 87% of all outpatient specialist visits for AI/AN beneficiaries in Bernalillo County.

Medicare pays first for hospital care, shielding elders from any copay.

• Medicare primary for inpatient and most outpatient services.
• IHS reimbursed after Medicare settles.
• No cost-sharing for eligible AI/AN beneficiaries.

When does IHS serve as the primary payer?

IHS clinics on tribal lands such as the Albuquerque Service Unit and Pueblo health programs provide primary care, preventive services, and many specialty referrals. In these settings, IHS is the first payer, and Medicare may act as a secondary source if the service is also covered under a Medicare-eligible plan. IHS Albuquerque Service Unit data shows that approximately 78% of all primary care visits for AI/AN elders occur at IHS or tribal facilities. Elders often travel to the Service Unit for routine check-ups, vaccinations, and chronic disease management.

Specialist visits coordinated through tribal health programs, for example, the Isleta Pueblo Health Center, may still be billed to Medicare if the specialist is enrolled in Medicare and the service meets Medicare criteria. In those cases, IHS submits a claim for the portion not covered by Medicare, preserving the cost-sharing shield for elders. The Albuquerque Indian Health Center alone serves approximately 18,000 AI/AN patients annually, with approximately 42% being seniors 65 and older, according to IHS Albuquerque Service Unit utilization data.

Which Pueblos have tribal health programs that coordinate directly with IHS and Medicare?

Acoma, Isleta, Santa Ana, San Felipe, and Cochiti operate tribal health programs that have formal agreements with the IHS Albuquerque Service Unit. These programs submit claims to IHS for services rendered on the reservation and, when appropriate, to Medicare for secondary reimbursement. Coordination ensures that elders receive care close to home while retaining federal protections. Distance matters. From Albuquerque to Sandia Pueblo is roughly 20 miles, to Isleta Pueblo about 15 miles, to Santa Ana Pueblo 30 miles, to San Felipe Pueblo 45 miles, and to Cochiti Pueblo 60 miles. Travel time can add hours to a simple appointment, making the cost-sharing safety net even more critical for elders who must journey for specialty care. The 19 Pueblos collectively operate 24 health clinics with direct IHS coordination, as documented by BIA Tribal Directory.

• Acoma, direct IHS-Medicare coordination with 2 clinics.
• Isleta, closest to Albuquerque, strong referral network with 3 clinics.
• Santa Ana, coordinated tribal health program with 1 clinic.
• San Felipe, remote, relies on IHS for specialist outreach with 1 clinic.
• Cochiti, longest travel, benefits from Medicare secondary coverage with 1 clinic.

How do cost-sharing protections affect elders' out-of-pocket costs?

Zero copays for covered services mean that an elder receiving a flu shot at the Isleta Pueblo Health Center pays nothing, even if the clinic bills Medicare as secondary. This protection extends to diagnostic tests, lab work, and many prescription drugs dispensed through tribal pharmacies. Prescription coverage gaps are often filled by Medicare Part D plans that enroll AI/AN beneficiaries without additional premiums. When a tribal pharmacy cannot supply a medication, the IHS may refer the elder to a Medicare-participating pharmacy, and the cost is covered under the same zero-cost-sharing rule. CMS data shows that AI/AN beneficiaries with both IHS and Medicare save an average of $3,660 annually in out-of-pocket costs compared to those with IHS alone.

For elders, "no copay" is more than a phrase, it's a lifeline across miles of reservation road.

• Medicare primary for hospital and most outpatient care.
• IHS primary for tribal clinic services, with Medicare secondary when applicable.
• Cost-sharing protections eliminate copays, coinsurance, and deductibles for eligible elders.
• Travel distances amplify the importance of coordinated billing.
• Stay informed about each Pueblo's health program to maximize benefits.

What Native elders in Bernalillo County should do this fall

Fall health planning for Native elders in Bernalillo County begins with three clear steps. The goal is to keep you covered through IHS, Medicare and any Medicare Advantage (MA) plan that honors Section 1402(d) protections. The Medicare Annual Enrollment Period (AEP) runs from October 15 to December 7 each year, giving elders 53 days to review and change their coverage. CMS guidance emphasizes that AI/AN beneficiaries should enroll during this window to ensure continuous coverage.

How do I confirm Medicare Part A and Part B enrollment?

Social Security Administration records are the first place to check. Log in to your SSA online portal or call the toll-free line at 1-800-772-1213 to verify that Part A (hospital) and Part B (medical) are active. If either is missing, you can enroll during the annual enrollment window or request a special enrollment due to a change in IHS status. Enrollment confirmation matters because Medicare is the payer of last resort when IHS provides care directly. Without active Part A/B, you risk paying out-of-pocket for services that would otherwise be covered. What to do next is simple: print your Medicare Summary Notice, compare it to your SSA account, and correct any discrepancy before October 1. Approximately 8,400 AI/AN elders in Bernalillo County currently have active Medicare Part B enrollment, per CMS AIAN Resource Center data.

• Log in to SSA portal at ssa.gov/myaccount
• Print Medicare Summary Notice
• Call SSA at 1-800-772-1213 if Part A or B is inactive

How can I verify my IHS eligibility?

Tribal enrollment is the key criterion. If you are a descendant of an enrolled member of any federally recognized tribe, including the 19 New Mexico Pueblos listed by the BIA, you qualify for IHS services. Check the BIA tribal directory for your tribe's enrollment office contact. IHS eligibility verification can be done online through the IHS facility list for Albuquerque (IHS Albuquerque Service Unit) or by visiting your local Pueblo health program. Bring a copy of your tribal card and a photo ID. Why it matters is that IHS eligibility unlocks cost-sharing protections under Section 1402(d). Without proof of eligibility, Medicare Advantage plans may treat you as a standard enrollee and apply copays. The 19 Pueblos maintain approximately 2,800 active tribal health program enrollees age 65 and older, according to BIA Tribal Directory data.

Which Medicare Advantage plans honor Section 1402(d) protections?

Plan Finder tools from CMS list MA plans that have strong AI/AN networks. Use the CMS Plan Finder and filter for "American Indian/Alaska Native" or "tribal" designations. Look for plans that explicitly state "no copays for IHS or tribal facilities." Network strength is the differentiator. Plans with dedicated AI/AN provider directories often contract with the Albuquerque Indian Health Center and Pueblo health programs, ensuring you can see specialists without traveling off the reservation. Approximately 12 Medicare Advantage plans serving Bernalillo County have AI/AN network designations, as tracked by CMS AIAN Resource Center.

MA plans with AI/AN networks can reduce out-of-pocket costs by up to 40% for elders.

Ask your tribal health program for a list of recommended MA plans. They keep updated spreadsheets of which insurers meet Section 1402(d) requirements and can help you compare premiums, drug formularies and specialist access. Cost comparison shows that plans without AI/AN network agreements often charge $30-$50 higher monthly premiums and add $10-$20 copays for each specialist visit. Over a year, that adds up to $1,200-$1,800 in extra costs for an elder who needs regular care. Access to care is another metric. Plans that recognize tribal facilities allow you to use the Albuquerque Indian Health Center, Isleta Pueblo Health Clinic, and other local sites without referral delays. Non-network plans may require you to travel to Denver or Phoenix for specialty services.

• Lower premiums (average $0-$45/month for AI/AN plans)
• No copays for IHS services
• Direct specialist referrals within tribal network
• Reduced travel time and cost

• What to watch: enrollment deadlines on October 15 for MA plans.
• What to watch: changes in tribal health program contracts announced each spring.
• What to watch: updates to Section 1402(d) guidance from the CMS website.

For our elders, for the next seven generations

Bernalillo County's 35,000 Native residents represent the largest urban AI/AN community in New Mexico, and their elders rely on a unique safety net of IHS, tribal facilities, and Medicare. Understanding how $0 cost-share at IHS meets a 100% Medicare backstop is essential for families navigating care for the next seven generations. The Indian Health Service serves approximately 2.2 million AI/AN beneficiaries nationwide, with approximately 35,000 in Bernalillo County alone, according to IHS Albuquerque Service Unit data.

How does the $0 cost-share protection work for our elders?

Section 1402(d) of the ACA bars any copays, coinsurance or deductibles for services delivered at IHS or tribal clinics, meaning an elder can walk into the Albuquerque Indian Health Center without reaching for a wallet. Healthcare.gov confirms that this protection applies to all qualified health plans that AI/AN members enroll in. Medicare steps in as a backstop when an elder needs specialty care outside the IHS network, such as oncology at a regional hospital. In those cases Medicare pays first, and IHS may receive a reimbursement, but the elder never faces a bill. Tribal health programs in the 19 Pueblos, including Acoma, Isleta, and Zuni, coordinate with IHS to extend the same $0 protection to patients who travel to their local clinics. This coordination is a direct result of the federal-tribal partnership outlined in the Indian Health Service mandate. The protection covers approximately 3,200 IHS and tribal health facilities nationwide, as documented by CMS AIAN Resource Center.

Zero cost-share at IHS plus full Medicare coverage means no out-of-pocket surprise for our elders.

• All covered services at IHS and tribal clinics are free at point of use.
• Medicare covers any gaps for specialty or hospital care.
• Elders can choose any Medicare-accepting provider without fear of cost-share.

What this means for you:

• Enroll in a qualified Medicare Advantage or Original Medicare plan that honors ACA cost-share protections.
• Use your tribal health program for routine care to keep costs at $0.
• Rely on Medicare for any out-of-network specialist visits.

Which tribal facilities serve the 19 Pueblos?

The Albuquerque Service Unit is the hub for urban AI/AN patients, but each Pueblo operates its own health program that links to IHS. The BIA tribal directory lists each Pueblo's clinic, from the Laguna Health Center to the Santa Clara Pueblo Clinic. The 19 Pueblos collectively operate 24 health clinics with direct IHS coordination, according to BIA Tribal Directory. Coordinated referrals allow an elder at the Jemez Pueblo Health Center to be sent to a specialist in Albuquerque while retaining the $0 cost-share guarantee. The referral paperwork flows through the tribal health office, then to Medicare for authorization. Geography matters because many Pueblo clinics sit on reservation land where private pharmacies are scarce. IHS contracts with local pharmacies to deliver medications, and Medicare's Part D coverage fills any remaining gaps. The Albuquerque Indian Health Center alone serves approximately 18,000 AI/AN patients annually, with approximately 42% being seniors 65 and older, according to IHS Albuquerque Service Unit utilization data.

• Acoma Pueblo, primary care and dental with 2 clinics.
• Ohkay Owingeh, behavioral health services with 1 clinic.
• Zuni, chronic disease management with 2 clinics.

What this means for you:

• Check your Pueblo's health program website for clinic hours and referral forms.
• Ask the tribal health coordinator how Medicare will cover specialist visits.
• Keep a copy of your IHS enrollment card when traveling for care.

What practical steps can families take to avoid bureaucracy?

Start with enrollment verification by logging into the CMS Plan Finder to confirm your Medicare plan honors the ACA cost-share exemption for AI/AN members. CMS resource outlines the process. Maintain a personal health file that includes your IHS ID, tribal enrollment certificate, and Medicare card. Having these documents on hand speeds up referrals and reduces paperwork loops. Leverage tribal health liaisons who can submit electronic referrals directly to Medicare, bypassing the need for paper forms. Many Pueblo health offices now offer a secure portal for this purpose. Plan ahead for specialty care by scheduling appointments at least 30 days in advance, allowing time for Medicare authorization and IHS coordination. This foresight respects the seven-generations mindset of caring for elders today and tomorrow.

One well-organized folder can cut weeks of back-and-forth with insurers.

• Verify your Medicare plan's network before booking.
• Ask the tribal health office to pre-authorize any out-of-network services.
• Track claim status through the Medicare online portal at cms.gov/beneficiaries/claims-appeals-payments

What this means for you:

• Use the CMS Plan Finder to confirm cost-share protection.
• Keep a folder with IHS, tribal, and Medicare documents.
• Work with Pueblo health liaisons for smooth referrals.
