Medicare Help Across Greater Sacramento

Communities We Serve

We provide free, independent Medicare guidance to residents across
Sacramento County, Placer County, and El Dorado County.

Summit Independent Insurance Services provides independent Medicare guidance to residents across Sacramento County, Placer County, and El Dorado County. Whether you are turning 65, leaving employer coverage, or reviewing your current plan during Annual Enrollment, our licensed agents compare Medicare Supplement (Medigap), Medicare Advantage, and Part D prescription drug plans at no cost to you. We meet clients by phone or in person at our Gold River office near the Sunrise Boulevard exit off Highway 50.

Residents in the following communities are within our primary service area, but Summit Independent Insurance Services serves all of California and is licensed in multiple states across the nation.
Each section below describes the local Medicare landscape, county-level plan options, and considerations specific to that community.

Sacramento County has one of the most competitive Medicare markets in California, with a broad selection of Medicare Advantage plans available for 2026 — including both network-based plans and Special Needs Plans — and all 11 Medicare Supplement plan letter types available through multiple carriers. A substantial majority of Medicare beneficiaries in Sacramento County are enrolled in Medicare Advantage, reflecting the plan variety and carrier competition this market supports.

For beneficiaries who prefer the flexibility of Original Medicare, Medicare Supplement premiums in California vary based on plan letter, age, sex, and tobacco use. The most widely enrolled Medigap plan letters in Sacramento County are Plan G and Plan N. Plan F, while still available from many carriers, is only accessible to Medicare beneficiaries who became eligible for Medicare before January 1, 2020. Anyone who turned 65 on or after that date is not eligible to enroll in Plan F, regardless of carrier availability.

California's Birthday Rule is a unique consumer protection worth understanding. It allows any Medicare Supplement policyholder in California to switch to an equal or lesser plan during a 60-day window beginning on their birthday each year, without medical underwriting. This applies to residents in every community in our service area and can represent a meaningful financial advantage for policyholders whose current Medigap premium has increased over time.[^8]

Key carriers active throughout Sacramento County include Kaiser Permanente (integrated HMO), UnitedHealthcare/AARP, SCAN Health Plan, Blue Shield of California, Aetna, Alignment Health, Wellcare, and Anthem Blue Cross. PACE programs — which provide comprehensive medical, dental, vision, prescription, transportation, and social services for seniors 55 and older — are available in Sacramento County through Sutter Senior Care PACE, InnovAge, and WelbeHealth.

Carmichael, CA

Sacramento County | ZIP: 95608, 95609, 95610, 95821, 95825, 95841

Carmichael is a large unincorporated community in northern Sacramento County with a 2026 population of approximately 81,833. The community has a median age of 40.1 years and approximately 15,946 seniors 65 and older. Medicare beneficiaries in Carmichael have access to the full Sacramento County plan portfolio, including both Medicare Advantage plans (HMO, HMO-POS, and PPO options) and all 11 Medigap plan letters for 2026.

The Sacramento County Medicare Advantage market includes plans at a range of premium levels — some with no monthly premium and others reflecting more comprehensive or specialized benefit structures. Medicare Supplement premiums in Carmichael vary by plan letter, carrier, age, and tobacco use; Plan G and Plan N are the most widely chosen options for beneficiaries newly enrolling in Medicare. Plan F remains available through multiple carriers in Carmichael but is only accessible to those who became Medicare-eligible before January 1, 2020. Carmichael residents also have access to stand-alone Medicare Part D prescription drug plans.

Carmichael borders Fair Oaks to the east and is well-served by the Sacramento County Medicare network. The community's proximity to Mercy San Juan Medical Center and Sutter Roseville makes both hospital systems accessible to Medicare beneficiaries choosing network-dependent plans.

Citrus Heights, CA

Sacramento County | ZIP: 95610, 95611, 95621

Citrus Heights is an incorporated city in the northeastern Sacramento metro area with a 2026 population of approximately 87,000. About 18.2% of residents are 65 or older — slightly above the national average — representing approximately 16,036 seniors. Medicare beneficiaries in Citrus Heights are covered under the Sacramento County plan offerings, giving them access to the full portfolio of Medicare Advantage plans and all 11 Medigap plan types available for 2026.

The city is bordered to the south by Carmichael and to the west by Fair Oaks, making it central within the northeastern Sacramento Medicare service corridor. Beneficiaries in Citrus Heights considering network-based Medicare Advantage plans should review provider directories to confirm access to Mercy San Juan, Sutter hospitals, and the UC Davis Health system, all of which serve this area.

Fair Oaks, CA

Sacramento County | ZIP: 95628

Fair Oaks is an unincorporated community in Sacramento County bounded by Carmichael to the west, Citrus Heights to the north, Orangevale to the east, and the American River to the south. It has a 2026 population of approximately 32,288 and a median age of 45.9 years. Approximately 8,236 seniors live in Fair Oaks. The community's median household income reflects a predominantly professional and retired residential base.

Fair Oaks residents are served by the full Sacramento County Medicare plan inventory, including all Medicare Advantage plan options and 11 Medigap plan types for 2026. The American River Parkway, which borders the southern edge of the community, is a feature frequently cited by residents as one of the reasons they prefer to age in place here — making Medicare plan stability and provider continuity particularly important considerations.

Folsom, CA

Sacramento County | ZIP: 95630, 95762 (eastern edge shares El Dorado County)

Folsom is a growing city in eastern Sacramento County with a 2026 population of approximately 86,388 and a median age of 41 years. About 12,422 residents are 65 or older. Folsom's median household income of $139,804 reflects its affluent, highly educated population, which tends toward comprehensive coverage preferences.

Medicare beneficiaries in the core 95630 ZIP code fall under Sacramento County's full Medicare Advantage plan portfolio and all 11 Medigap plan letters. Residents in the easternmost parts of Folsom near El Dorado Hills (ZIP 95762) may fall under El Dorado County's more limited Medicare Advantage plan selection. This geographic boundary is an important distinction — beneficiaries just east of the county line have meaningfully different plan availability, which is one reason a review with a local independent agent matters for Folsom residents near the county border.

Folsom is home to Mercy Folsom hospital, which is an important network consideration for Medicare Advantage HMO plan selection. The city's proximity to both Sacramento and El Dorado Hills gives residents practical access to multiple hospital systems.

Gold River, CA

Sacramento County | ZIP: 95670

Gold River is a small, affluent planned community in Sacramento County, situated between Rancho Cordova, Folsom, and the American River. It has a population of approximately 7,603, making it one of the smallest communities in our service area — but also one of the most senior-heavy, with approximately 34% of its adult residents being 65 and older. Gold River has the highest median family income of any community in Sacramento County.

Gold River is the home of the Summit Independent Insurance Services office, located near the Sunrise Boulevard exit off Highway 50. Residents here access the full Sacramento County Medicare plan portfolio, including all Medicare Advantage plan options and 11 Medigap plan types for 2026. Given Gold River's high concentration of seniors relative to its total population, the community has significant demand for both Medigap and Medicare Advantage guidance. Many Gold River residents are evaluating plan changes as their circumstances evolve post-retirement, and California's Birthday Rule gives them an annual opportunity to switch Medigap plans without underwriting.

Mather, CA

Sacramento County | ZIP: 95655

Mather is a small community in eastern Sacramento County, near Rancho Cordova, formerly the site of Mather Air Force Base. It has a 2026 population of approximately 4,793 and a median age of 34.1 years — the youngest community in this service area. About 495 seniors live in Mather. Its median household income reflects its character as a mixed residential and commercial area serving former military and government-adjacent families.

Mather residents are covered under Sacramento County's Medicare plan portfolio, including all Medicare Advantage plans and 11 Medigap plan types for 2026. While Mather's senior population is smaller than neighboring communities, many military retirees in the area have questions about how TRICARE For Life interacts with Medicare — a coordination-of-benefits topic that independent Medicare agents are well-positioned to address.

Orangevale, CA

Sacramento County | ZIP: 95662

Orangevale is an unincorporated community in northeastern Sacramento County, east of Citrus Heights and north of Folsom. It has a population of approximately 35,000 and a median age slightly above the California average. The community is primarily residential with a strong suburban character.

Orangevale residents are served under the Sacramento County Medicare plan portfolio, including all Medicare Advantage plans and 11 Medigap plan types for 2026. As a community adjacent to both Citrus Heights and Fair Oaks, Orangevale beneficiaries have practical access to the same hospital systems serving northeastern Sacramento County, including Mercy San Juan and Sutter facilities. Plan selection should factor in which medical groups are contracted with the chosen Medicare Advantage carrier for this ZIP code, as network boundaries can shift between neighboring communities.

Rancho Cordova, CA

Sacramento County | ZIP: 95670, 95741, 95742, 95827

Rancho Cordova is an incorporated city in eastern Sacramento County, sharing its western border with Gold River and its northern border with Folsom. It has a 2026 population of approximately 86,354 and a median age of 36 years — the youngest city in this service area. About 10,134 seniors 65 and older live in Rancho Cordova. The city is one of the most diverse communities in the area, with significant Asian, Black or African American, Hispanic, and multiracial populations alongside its White majority.

Rancho Cordova residents are covered under the full Sacramento County Medicare plan portfolio, including all Medicare Advantage plans and 11 Medigap plan types for 2026. The city's diverse population includes communities where Spanish-language Medicare guidance and culturally appropriate outreach are relevant. Summit Independent Insurance Services serves all Rancho Cordova ZIP codes and can meet clients at local venues or by phone and video call for those who prefer not to travel to our Gold River office.

El Dorado County residents face a noticeably different Medicare landscape than their neighbors in Sacramento County. The Medicare Advantage market in El Dorado County is significantly more limited — both in the number of available plans and the range of carrier options — and out-of-pocket cost structures tend to run higher than in Sacramento County. For many El Dorado County residents, particularly those who travel frequently or want the freedom to see any Medicare-accepting provider without network restrictions, a Medicare Supplement plan paired with a stand-alone Part D prescription drug plan often provides more practical flexibility than an HMO-based Medicare Advantage plan. This county-line distinction is one of the most important planning factors for residents near the Sacramento–El Dorado border.

El Dorado Hills, CA

El Dorado County | ZIP: 95762

El Dorado Hills is a master-planned community in western El Dorado County, approximately 25 miles east of Sacramento. It has a 2026 population of approximately 51,000 and a median age of 45.7 years — one of the highest in the region. About 10,635 seniors 65 and older live in El Dorado Hills, representing roughly 21% of the population.

For 2026, El Dorado County offers a more limited selection of Medicare Advantage plans than neighboring Sacramento County, and a smaller share of those plans carry no monthly premium. The reduced plan competition in El Dorado County means that out-of-pocket maximums and premium levels tend to be less favorable than what Sacramento County beneficiaries have access to. Kaiser Permanente is the most widely enrolled carrier in El Dorado County's Medicare Advantage market and operates an integrated HMO model in this area.

For Medicare Supplements, El Dorado Hills residents have access to all 11 plan types available throughout California — with premiums varying by plan letter, age, sex, and tobacco use. Plan G and Plan N are the most widely chosen options for beneficiaries newly enrolling in Medicare. Plan F remains available through multiple carriers but is only accessible to those who became Medicare-eligible before January 1, 2020. Given the more limited Medicare Advantage network in El Dorado County, many El Dorado Hills residents find that a Medicare Supplement paired with a stand-alone Part D plan offers broader access to providers across the region.

The Summit Independent Insurance Services office is located in Gold River, located just off Highway 50 near the Sunrise Boulevard exit, is among the closest independent Medicare agencies to El Dorado Hills. We meet clients in person at our office, at their home, or at a location in the El Dorado Hills area that is convenient for them.

Placerville, CA

El Dorado County | ZIP: 95667

Placerville is the county seat of El Dorado County, located approximately 45 miles east of Sacramento in the Sierra Nevada foothills. It has a population of approximately 10,730 and one of the highest senior concentrations of any community in this service area — 22.4% of residents are 65 or older, compared to 16.8% nationally. The median age is 46.2 years, and the largest single age cohort is 60 to 64 years, signaling a large wave of near-Medicare-eligible residents in the community.

Placerville residents are covered under El Dorado County's Medicare plan portfolio, which offers significantly fewer Medicare Advantage plan choices than Sacramento County for 2026. Given Placerville's rural character and limited Medicare Advantage network, many residents find that Medicare Supplement Plan G — which provides comprehensive coverage and allows access to any provider who accepts Medicare nationwide — is better suited to their needs than an HMO-based Advantage plan. All 11 Medicare Supplement plan types are available in Placerville through multiple carriers. Plan F is available to beneficiaries who became Medicare-eligible before January 1, 2020; those who became eligible after that date are not eligible for Plan F. Marshall Medical Center in Placerville is the primary hospital serving the community and is an important factor in evaluating network-based plan options.

Placer County offers a notably competitive Medicare Advantage market compared to El Dorado County, with a broad selection of plans for 2026 — including Special Needs Plans (SNPs) for those with dual Medicare-Medicaid eligibility or specific chronic conditions. The majority of Placer County Medicare Advantage plans have earned strong quality ratings from CMS, and plan types include HMO, HMO-POS, and PPO options. For beneficiaries who prefer Medicare Supplement coverage, all 11 plan letter types are available through carriers active in the Placer County market.

Granite Bay, CA

Placer County | ZIP: 95746

Granite Bay is a census-designated place in western Placer County, bordered by Roseville to the north and Folsom Lake to the east. It has a 2026 population of approximately 21,603 and a median age of 47.2 years — the second-oldest median age in this service area. About 4,871 seniors live in Granite Bay, representing approximately 23% of the population. The community's median household income is among the highest in the greater Sacramento region.

Granite Bay residents are served under Placer County's Medicare plan portfolio, which includes a strong selection of Medicare Advantage plans for 2026 — including Dual Eligible SNPs (D-SNPs) and multiple Chronic Condition SNPs. A meaningful share of these plans carry no monthly premium, and the majority have earned strong quality ratings from CMS. For Medicare Supplements, Granite Bay residents access the same 11 plan types available across California. Given the community's high-income retiree population, Plan G — which provides comprehensive coverage with a predictable annual cost — is frequently well-suited to the coverage preferences common in this area.

Roseville, CA

Placer County | ZIP: 95661, 95678, 95747

Roseville is the largest city in Placer County and one of the fastest-growing cities in the Sacramento region. It has a 2026 population of approximately 156,000 and a median age of 40.2 years. About 27,180 seniors 65 and older live in Roseville, representing 17.1% of the population — in line with the national average.

Roseville residents access Placer County's Medicare plan portfolio, which includes a robust selection of Medicare Advantage plans for 2026 across HMO, HMO-POS, and PPO structures, with multiple options available at no monthly premium. A majority of Medicare beneficiaries in the Roseville area are enrolled in Medicare Advantage, reflecting the strong carrier competition this market supports. Roseville is home to Sutter Roseville Medical Center and Kaiser Permanente's Roseville campus, both of which are significant network considerations for beneficiaries choosing HMO-based Medicare Advantage plans. The city's large and growing senior population means robust competition among carriers, which typically benefits beneficiaries by keeping premiums competitive. For residents approaching age 65, the seven-month Initial Enrollment Period and the decision between Medicare Advantage and Medicare Supplement represent the most important near-term planning exercise.

Frequently Asked Questions

Do you serve clients outside of these specific communities?
Yes. We are licensed in multiple states and work with many families all across California. While the communities listed above represent Summit Independent Insurance Services’ primary service area, we also assist clients throughout the broader Sacramento metro region, including North Sacramento, Elk Grove, Antelope, Lincoln, Rocklin, Cameron Park, and surrounding unincorporated areas. If you are unsure whether we serve your location, contact our office.

Can I compare plans by phone or instead of meeting in person?
Yes. Most of Summit Independent Insurance Services' client consultations are conducted by phone. While in-person appointments are available at our Gold River office near Highway 50 and Sunrise Boulevard, or at a location convenient to you, many clients resolve their needs over their phone.

What does your service cost?
Summit Independent Insurance Services’ Medicare and health insurance guidance is available at no cost to clients. We are licensed independent agents compensated by insurance carriers when a client enrolls in a plan. As an independent agency, we are not captive to any single carrier and can compare plans from the major carriers available in your county.

When should I contact a Medicare agent?
The most important times are: within three months of turning 65, when leaving employer-sponsored health coverage at any age, during Medicare's Annual Enrollment Period (October 15–December 7 each year), and during your annual birthday window if you have a Medicare Supplement and want to explore switching plans under California's Birthday Rule.

What is the difference between Medicare Advantage and Medicare Supplement?
Medicare Advantage (Part C) replaces Original Medicare with a private plan — typically an HMO or PPO — that often includes drug coverage and additional benefits like dental and vision, usually at lower monthly premiums. Medicare Supplement (Medigap) works alongside Original Medicare to cover out-of-pocket costs like deductibles and coinsurance, offering broader provider access at higher monthly premiums. The right choice depends on your health, medications, preferred providers, travel patterns, and financial situation.

What is California's Birthday Rule?
California's Birthday Rule allows Medicare Supplement policyholders to switch to an equal or lesser Medigap plan during a 60-day window that begins on their birthday each year, without going through medical underwriting. This is a California-specific consumer protection that gives Medigap policyholders an annual opportunity to shop for lower premiums without risking coverage denial. It applies to all communities in the Summit Independent Insurance Services service area.
