TL;DR — The Short Answer
- Use IHS (Northern Navajo Medical Center, Shiprock) for primary and preventive care — it's a treaty right, free at the point of service, and enrolling in Medicare does NOT cancel it.
- Use Medicare to pay IHS back — and to access San Juan Regional Medical Center in Farmington (2-star CMS rating) for acute and specialty care IHS can't fully provide.
- 27.1% of San Juan County seniors aged 65+ have lost all their teeth (CDC PLACES 2022) — a gap neither IHS nor Original Medicare covers well. A Medicare Advantage plan with dental benefits may be your only real option, but check the network distance first.
What is IHS, and why do I still have it at 65 — isn't that only for people who can't afford insurance?
Let's put this to rest right now: the Indian Health Service is not a welfare program. It is not charity. It is not a benefit the government chose to give Native people out of kindness. It is a treaty obligation — the United States government promised healthcare to Native peoples in exchange for hundreds of millions of acres of land. If you are an enrolled member of a federally recognized tribe and live in a service area, you are entitled to IHS care. Full stop. At 35. At 55. At 65. At 85.
What changes when you turn 65 is that Medicare becomes available to you. And here's the thing most people — including many IHS staff — don't explain clearly: enrolling in Medicare makes IHS stronger, not weaker. When you are a Medicare beneficiary and IHS provides your care, IHS can bill Medicare and collect reimbursement. That money goes back into the facility budget. It stretches the chronically underfunded IHS appropriation further. Enrolling in Medicare Part A and Part B is one of the most tribe-supportive financial decisions you can make when you turn 65.

That 39.4% disability rate matters. Many Navajo elders turning 65 have been on Medicare longer than they realize — some qualify for Medicare at 65 automatically if they were on Social Security disability for 24 months prior. If that describes you or your family member, the coordination questions are different. Talk to your tribal benefits coordinator.
The two hospitals in San Juan County — which one serves me under IHS and which one takes Medicare?
San Juan County has exactly two hospitals. Two. For a population of 120,675. Here they are, and they are not the same kind of facility:
Northern Navajo Medical Center
IHS Facility📍 US Hwy 491 North, Shiprock, NM 87420
📞 (505) 368-6001
CMS Star Rating: Not Available (IHS facilities operate under a separate federal framework, not CMS hospital ratings)
Primary system: IHS. For enrolled tribal members, services are provided at no cost-sharing. When you enroll in Medicare, IHS bills Medicare on your behalf — you still pay nothing.
San Juan Regional Medical Center
Medicare-Rated📍 801 West Maple Street, Farmington, NM 87401
📞 (505) 609-2000
CMS Star Rating: 2 out of 5 stars (CMS Hospital Compare)
Primary system: Acute care. Accepts Medicare assignment. Has emergency services. If IHS refers you here — or if you arrive in emergency — Medicare Part A covers inpatient, Part B covers outpatient.
That 2-star rating at San Juan Regional is worth noting. It's not a failing grade, but it's below the national average. When our elders are referred out of IHS to Farmington for specialty care, they are going to a facility rated below the national median. That context matters when you're comparing "just use Medicare" against the reality of what Medicare buys you here.

Here's the honest answer: it depends on what you need and what IHS can actually provide on any given day. The Purchased/Referred Care (PRC) program exists specifically for the gap — when IHS can't provide the service, PRC is supposed to fund a referral out to a Medicare or private provider. "Supposed to" is doing a lot of work in that sentence. PRC funds run out. Referrals get denied. That's the reality.
But here's the practical decision table for the most common health needs of San Juan County seniors, based on the CDC PLACES data for this county:
| Health Need | Use IHS First? | Medicare Role | San Juan County Data |
|---|---|---|---|
| Blood pressure medication | ✓ Yes | Part D covers most antihypertensives; IHS pharmacy is free for enrolled members | 73.5% of adults with high BP are taking medication (CDC PLACES 2023) — strong. Keep the chain unbroken. |
| Arthritis / joint pain | ✓ Yes | Part B covers rheumatology specialist visit if referred; orthopedic surgery via SJRMC | 24.6% of adults report arthritis (CDC PLACES 2023) — nearly 1 in 4 |
| Colorectal cancer screening | ✓ Yes | Part B covers colonoscopy with $0 cost-sharing for preventive screening | Only 49.1% screened (CDC PLACES 2022) — just under half. The other half is unprotected. |
| Dental care / tooth loss | ✓ Try IHS first | Original Medicare: no dental coverage. Medicare Advantage: check plan dental benefits and network distance | 27.1% of seniors aged 65+ have lost ALL teeth (CDC PLACES 2022) — highest-stakes gap in this county |
| Hearing aids / hearing care | ✓ Try IHS first | Original Medicare: limited. Some MA plans cover hearing aids. Verify in-network audiologist location. | 9.4% report hearing disability (CDC PLACES 2023) |
| Emergency / acute hospitalization | Use SJRMC or NNMC ER | Part A covers inpatient at SJRMC; IHS ER covered at NNMC with Medicare billing | SJRMC: 2-star; NNMC: nearest IHS emergency services |
| Mental health / loneliness | ✓ Yes | Part B covers outpatient mental health at 80% after deductible | 37.1% of adults report loneliness (CDC PLACES 2023) — this is a health crisis, not a feelings question |
What does the health data actually show for San Juan County seniors in 2026?
Let's look at the numbers that should be driving care decisions — and enrollment decisions — for every newly eligible 65-year-old in this county right now.
That loneliness number — 37.1% — is not a soft metric. Chronic loneliness is associated with higher rates of dementia, cardiovascular disease, and mortality. It's as predictive of early death as smoking 15 cigarettes a day. In a county where IHS facilities are the social hub of many rural communities, and where the nearest specialist may be in Albuquerque or Durango, isolation is a healthcare issue. Medicare's Annual Wellness Visit (covered at $0 under Part B) includes a depression screening. That's one small tool. Use it.
The other 50.9% are unscreened. Medicare Part B covers this at $0 for preventive purposes. IHS can order the test. There is no excuse for this gap except the system not doing its job.
What does the 7-month enrollment window mean, and what happens if I miss it?
When you turn 65, the Social Security Administration gives you a 7-month Initial Enrollment Period (IEP): three months before your birthday month, your birthday month itself, and three months after. If you were already receiving Social Security benefits, you're enrolled in Part A automatically. Part B is a choice — and a monthly premium.
The 2026 standard Part B premium is $185.00/month. If you miss your IEP and don't have a qualifying Special Enrollment Period (SEP), you face a 10% lifetime penalty for every 12-month period you delayed. Wait two years, that's a 20% penalty added to every premium you'll ever pay. Forever.
American Indian and Alaska Native Medicare beneficiaries have a Special Enrollment Period that allows them to join, switch, or drop Medicare Advantage plans once per calendar quarter (January–March, April–June, July–September, October–December). This is a CMS rule specifically for our community. It does NOT waive the Part B late enrollment penalty, but it does give you more flexibility with Medicare Advantage plans than any other group of beneficiaries.
One more thing on premiums: if your income is limited, the New Mexico Human Services Department administers Medicare Savings Programs (MSPs) that can pay your Part B premium and eliminate your Part A deductible. In a county where 24.1% of adults receive food stamps (CDC PLACES 2023), a significant number of our elders likely qualify and are not enrolled. This is money sitting on the table.
Should I add a Medicare Advantage plan or stay with Original Medicare in San Juan County?
This is the question where I will not tell you which plan to pick — that's not what we do here, and anyone who tells you "definitely choose Plan X" without knowing your specific situation and your specific IHS service unit does not understand how this works. What I can tell you is what the terrain looks like.
San Juan County has Medicare Advantage plans available. You can find the complete current plan landscape at CMS Medicare Plan Finder (medicare.gov/plan-compare) — enter your zip code and browse all plans available to you. The count changes each year. Some plans offer $0 premiums but have network restrictions that matter enormously when your nearest in-network provider is 45 miles away in Farmington.
The specific calculus for IHS users is this: if you enroll in a Medicare Advantage plan (Part C), you are enrolled through a private insurer, not Original Medicare. IHS facilities can bill Original Medicare (Parts A and B) directly. Some IHS and Tribal facilities are not in-network for every Medicare Advantage plan. Before enrolling in any MA plan, call Northern Navajo Medical Center at (505) 368-6001 and ask: "Is my IHS facility in-network for [Plan Name]?" That one phone call can save you an enormous headache.
If you want to keep IHS as your primary care home and use Medicare as the billing backstop — which is the strategy most IHS benefit coordinators recommend — Original Medicare (Parts A and B plus a standalone Part D drug plan) may give you the cleanest coordination. Medicare Advantage adds benefits (dental, vision, hearing) that matter in a county with 27.1% total tooth loss, but the network geometry has to work first.
