Humana Medicare Advantage: PPO vs. HMO Explained

8 min read

Most people don't pick between a Humana HMO and a Humana PPO because they compared the two. They pick because a commercial mentioned a $0 premium, or because their neighbor has one and likes it. That's a reasonable way to end up with decent coverage, but it skips the part that actually determines how the plan behaves once you're sick: whether you're locked into a network or not. I went through Humana's 2026 numbers, the national averages, and the actual CMS mechanics to lay out what genuinely differs.

The Basic Difference Between HMO and PPO

An HMO asks you to pick a primary care doctor from its network, and that doctor coordinates your care and refers you to specialists when needed. Step outside the network for anything non-emergency, and you're typically paying the full cost yourself. A PPO drops both requirements: no primary care gatekeeper, no referral, and out-of-network care is still covered, just at a higher share of the cost. That flexibility is the entire reason PPOs charge more. HMO-POS plans sit in between, using an HMO's network structure but allowing occasional out-of-network care at a higher price, without a referral.

What Medicare Advantage Costs, Nationally, in 2026

Across the country, 61% of Medicare Advantage enrollees with drug coverage are in HMOs and 38% are in local PPOs, according to KFF's 2026 analysis of CMS enrollment data. The gap in what they pay is real but smaller than you'd expect: HMO enrollees average $12 a month in supplemental premiums, PPO enrollees average $18. Three quarters of enrollees pay no premium at all beyond the standard Part B premium of $202.90.

Where the numbers diverge more sharply is the annual out-of-pocket ceiling. Every plan must cap in-network costs at $9,250 in 2026, but the actual average enrollees face is $4,636 for HMOs versus $6,592 for PPOs. PPO enrollees who also use out-of-network care face a combined ceiling that can run up to $13,900, with $9,825 as the national average.

Where Humana Lands

Humana's own numbers track the national pattern, with some notable gaps. Its HMO plans average $3 a month, with 83% carrying no premium at all, and an average out-of-pocket ceiling of $4,856, per MoneyGeek's 2026 analysis of CMS filings. Its PPO plans average $14 a month, only 15% at $0 premium, with a $7,200 ceiling, about $934 above the national PPO average.

On quality, the picture is more mixed than a single number suggests. Humana disclosed an enrollment-weighted average CMS star rating of 3.61 for 2026 in a regulatory filing, roughly flat from 2025. "We're not satisfied with those results, to be very clear," Humana CEO Jim Rechtin told investors on an October call. Broken out by plan type, MoneyGeek's analysis found Humana's PPO tier actually scores 3.86, ahead of the 3.63 national PPO average, while its HMO tier scores 3.73, slightly below the 3.86 national HMO average. The weakest spot is HMO-POS, at 3.57 against a 4.01 national average, a gap driven mostly by care coordination and health outcome measures. If you're managing a chronic condition and considering that specific plan type, it's worth checking your county's actual rating on Medicare's Plan Finder before enrolling, since county-level scores can differ from the statewide picture.

The States Where You Don't Get a Choice

In Connecticut, Delaware, Massachusetts, Minnesota, Vermont, Wyoming, and Washington, D.C., Humana only sells PPO plans. There's no HMO tier to compare against, so the "which one costs less" question doesn't apply there, you're looking at the PPO's $7,200 average ceiling either way. Texas and Florida sit at the other extreme, with dozens of Humana HMO and PPO plans each, giving residents there the most room to actually compare.

Do You Get Fewer Extras on an HMO?

This is where a lot of people assume they're trading benefits for a lower premium, and that's mostly not how it works. Nationally, 98% of Medicare Advantage enrollees are in plans with dental coverage, 95% with hearing, and more than 99% with vision, according to KFF, and that holds across HMO and PPO plans about equally. Humana's own plans follow the same pattern: most, including the Humana Gold Plus HMO series, cover preventive dental (cleanings, X-rays) plus restorative work like fillings and crowns, and every 2026 Humana plan includes routine vision. The dollar caps on those benefits vary by specific plan and county, not by whether it's an HMO or PPO, so don't assume a PPO buys you richer extras. It doesn't, it buys you network flexibility.

Prescription Drug Coverage Works the Same Way

Most Humana Medicare Advantage plans, HMO and PPO alike, bundle Part D drug coverage, and many offer $0 copays on Tier 1 and Tier 2 medications (most generics) at preferred pharmacies. Humana offers both basic plans, which meet Medicare's minimum drug coverage requirement, and enhanced plans, which add coverage for brand-name and specialty drugs the basic tier excludes. If you take an ongoing prescription, checking that specific drug against a plan's formulary matters more than checking whether the plan is an HMO or a PPO.

Referrals, Emergency Care, and the Network Question

The referral requirement is where most people feel the HMO-versus-PPO difference in daily life. Need to see a cardiologist under an HMO, and you typically go through your primary care doctor first. Under a PPO, you call the cardiologist directly. That difference matters more for people who see multiple specialists regularly than for people who mostly need annual checkups.

One thing doesn't change regardless of which you pick: every Medicare Advantage plan is required to cover emergency and urgently needed care anywhere in the country, in-network or not. An HMO won't leave you stranded if you have a heart attack while traveling. What it will do is apply normal network rules to everything that isn't an emergency, including follow-up care after you're stable.

Which One Actually Fits You

If your doctors are already in a Humana HMO network and you're comfortable with referrals, the HMO tier gets you the lowest premium and the lowest annual ceiling, hard to beat on cost. If you split time between two states, travel often, or want to see specialists without asking permission first, the PPO's flexibility is worth its higher price to a lot of people. Neither answer is generically correct, and the specific plan available in your county, not just the plan type, is what actually determines your costs and network. Medicare's Plan Finder at medicare.gov lets you compare real plans by ZIP code, and a free SHIP counselor (State Health Insurance Assistance Program) can walk through the comparison with you at no cost if the options feel overwhelming.

Frequently Asked Questions

Is Humana HMO or PPO cheaper?

HMO, on both counts that matter: Humana's HMO plans average $3 a month versus $14 for PPO, and the annual out-of-pocket ceiling is about $2,344 lower on average for HMO. The trade-off is network flexibility, not just price.

Do I need a referral for a Humana PPO?

No. PPO and PFFS members can see any Medicare-approved provider who accepts the plan's terms without a referral. HMO members generally need one from their primary care doctor to see a specialist.

Does Humana HMO cover out-of-network care at all?

Generally no, except for emergency and urgently needed care, which every Medicare Advantage plan must cover nationwide regardless of plan type. Non-emergency out-of-network care under an HMO is typically your full responsibility.

Why is Humana's star rating different for HMO versus PPO?

CMS rates each plan type separately based on care coordination, outcomes, and member satisfaction. Humana's PPO tier scores above the national PPO average (3.86 vs. 3.63) while its HMO and HMO-POS tiers score below their respective national averages, so the "Humana" brand name alone doesn't tell you the quality of a specific plan.

Can I switch from a Humana HMO to a Humana PPO later?

Only during specific enrollment windows, generally the annual Medicare Advantage Open Enrollment Period or your state's enrollment periods. You can't switch plan types whenever you want mid-year outside of a qualifying event.

Can I switch into a 5-star Humana plan outside of open enrollment?

Yes, if one is available in your area. CMS allows a one-time 5-star Special Enrollment Period between December 8 and the following November 30 to switch into any plan rated 5 stars, regardless of your current plan type. Use Medicare's Plan Finder to check what's available by ZIP code.

Conclusion

The HMO-versus-PPO decision comes down to one trade: pay less and stay in-network, or pay more for the freedom to go outside it. Humana's own 2026 numbers make that trade unusually clear, a $3 HMO premium against a $14 PPO premium, a $4,856 ceiling against a $7,200 one. What the marketing won't tell you is that Humana's PPO actually out-scores its HMO on CMS quality ratings this year, so the "flexibility costs you quality" assumption doesn't hold here. Check the actual plan in your county before assuming either direction, the averages are a starting point, not your answer.
