Oscar Health, built specifically for the ACA marketplace in 2012, posts one of Florida's lowest 2026 increases at 26.4% but sells only in select metro counties. UnitedHealthcare is the nation's largest health insurer, but its Florida individual-marketplace footprint for 2026 is selective rather than statewide. Both compete on Florida's 2026 ACA marketplace, where 16 insurers now participate and the statewide weighted-average rate rose roughly 31.5% before subsidies — but the two carriers take very different approaches to networks, plan types, and price.
This comparison breaks down how Oscar and UnitedHealthcare differ on county availability, provider networks, plan types, 2026 premiums, and member experience — and which type of Florida enrollee each one fits best.
Comparing ACA plans in Florida
$0 telehealth and a leading app: Oscar offers $0 virtual visits 24/7 through its app for many common conditions — a standout for Bronze and high-deductible enrollees who would otherwise pay full price for office visits before meeting the deductible. Its app is consistently among the highest-rated in health insurance.
Dedicated Care Teams: Instead of a rotating call center, Oscar assigns each member a small Care Team of guides and a nurse who handle every interaction, creating continuity that traditional carriers rarely match.
Competitive metro pricing: In the counties where Oscar competes — primarily South Florida, Central Florida, and the Tampa Bay region — its Silver HMO plans are often among the lowest-cost, and its 26.4% approved increase for 2026 is one of the gentlest among Florida carriers.
National scale and brand: UnitedHealthcare is the largest health insurer in the country, and its size brings deep resources, a polished member app, and integration with Optum's pharmacy and care-management services.
Digital tools and virtual care: UnitedHealthcare's app and virtual-visit options make routine care and prescription management convenient, and its provider-finder tools are mature and well-maintained.
Optum integration: Members benefit from UnitedHealthcare's tie-in with Optum for pharmacy, behavioral health, and care coordination — a vertically integrated model few Florida competitors can match.

|---|---|---|
| Founded / status | 2012 (ACA-native) | National carrier; selective FL individual footprint |
| Plan types | HMO only | HMO / EPO |
| Florida county availability | Select metro counties | Select FL counties |
| Telehealth | $0 telehealth via Oscar app (24/7) | Virtual visits included |
| Provider network | Narrower; curated metro networks | Large nationally; narrower for FL individual plans |
| Out-of-network coverage | Emergency only | Emergency only |
| Signature feature | Dedicated Care Team; top-rated app | National brand; UnitedHealthcare app + Optum |
| 2026 approved rate change | +26.4% (one of the lowest in FL) | +29.9% |
Oscar's Florida networks are curated rather than comprehensive — selected hospitals and physician groups in the metros it serves, HMO-only, with no out-of-network coverage except emergencies. Because Oscar is not statewide, your first check is simply whether it is sold in your county at all.
UnitedHealthcare's national employer network is enormous, but its Florida individual-marketplace network for 2026 is narrower and offered in select counties only as HMO/EPO plans — with out-of-network care covered for emergencies only. Do not assume the broad UnitedHealthcare employer network you may know carries over to its individual plans.
The network gap between these two carriers is the single most important thing to check before you enroll, because an ACA plan only pays in full when you stay in its network.
Sticker premiums rose across the board for 2026 — Florida's statewide weighted average climbed about 31.5% before subsidies. The illustrative Silver-plan figures below show how Oscar and UnitedHealthcare compare in counties where both compete.
| County (35-yr-old, non-smoker, Silver) | Oscar | UnitedHealthcare |
|---|---|---|
| Miami-Dade County | ~$480/mo | ~$510/mo |
| Orange (Orlando) County | ~$450/mo | ~$485/mo |
| Hillsborough (Tampa) County | ~$440/mo | ~$475/mo |
Approximate 2026 unsubsidized premiums for a 35-year-old non-smoker, before APTC subsidies. What you actually pay is set by the benchmark Silver plan in your rating area; more than 95% of Florida enrollees qualify for a subsidy. As a reference point, regulators cited a 28-year-old in Duval County on a Silver plan moving from about $149 to roughly $281 per month for 2026.
