How Do I Read a Medicare Advantage Summary of Benefits?
It is the one document every plan has to hand you before you join, and it is built for side-by-side reading. Here is the order we read it in, what each line means, and the two things it never tells you.
The bottom line
- It is a summary, by law. Federal rules require a short, clear table of the most-used benefits, given to you with the enrollment form.
- Read three lines first: the out-of-pocket maximum, the drug deductible and the tiers it applies to, and the copays for care you actually use.
- It never names your doctors or your drugs. Check the provider directory and the drug list separately, before anything else.
- The lines really do differ. Across Albuquerque's 19 general plans with drug coverage for 2027, maximums run $3,800 to $8,000 and drug deductibles $200 to $700.
- When in doubt, the Evidence of Coverage wins. It is the full rulebook; the summary is the short version.
Read a Medicare Advantage Summary of Benefits from the bottom of your risk up, not from the top of the page down. Start with the maximum out-of-pocket amount, then the drug deductible and which drug tiers it applies to, then the copays for the care you use most. Leave the monthly premium for last. Before any of it, confirm your doctors are in the plan's network and your prescriptions are on its drug list, because the summary does not show either. Federal rules define the document as "a summary of highly utilized coverage that include benefits and cost sharing" (42 CFR 422.2267(e)(5)). It is a tool for comparing plans, and it works well once you know which lines carry the weight. Reading the summary is one of the eight steps in our complete guide to comparing 2027 Medicare Advantage plans.
What is a Summary of Benefits?
It is the short document a Medicare Advantage plan is required to give you before you join. The federal marketing rules say plans "must disseminate a summary of highly utilized coverage that include benefits and cost sharing to prospective enrollees, known as the SB," and that it "must be in a clear and accurate form." It has to arrive with the enrollment form: "in hard copy with a paper enrollment form," or, for online enrollment, "made available electronically (for example, via a link) prior to the completion and submission of enrollment" (42 CFR 422.2267(e)(5)).
Two things follow from that. First, you should never be asked to sign up for a plan without a chance to see its summary. Second, the rule calls it a "model" document. CMS supplies a model, but each company lays out its own, so the order and wording differ from plan to plan. The lines below are the ones you will find on nearly all of them, under slightly different headings.
Summary, Evidence of Coverage, ANOC, EOB: which is which?
Plans send four documents with similar names. Each answers a different question:
| Document | When you get it | What it contains | Use it for |
|---|---|---|---|
| Summary of Benefits (SB) | Before you enroll; it must come with the enrollment form | A short table of the most-used benefits and what you pay for each | Comparing plans side by side |
| Evidence of Coverage (EOC) | Current members by October 15; new members after enrolling | The full rulebook: every covered service, every cost, every rule and how to appeal | Settling exactly what is covered |
| Annual Notice of Change (ANOC) | Current members each fall | What is different about your own plan next year | Deciding whether to stay or look |
| Explanation of Benefits (EOB) | After you get care, monthly or quarterly | What was billed, what the plan paid, what you owe, and your progress toward the maximum | Checking bills during the year |
Source: 42 CFR 422.2267(e) (Summary of Benefits; Evidence of Coverage due to current members by October 15; Part C EOB "monthly or per claim with a quarterly summary"); CMS, marketing models and standard documents.
The Evidence of Coverage is long. CMS's 2027 model version has twelve chapters, including "Medical Benefits Chart (what's covered and what you pay)," two chapters on drug coverage and drug costs, and one on coverage decisions and appeals (CMS CY2027 model materials). The summary pulls the most-used rows out of that chart. If you already have a plan, your Annual Notice of Change shows what moved for next year; our ANOC checklist walks through it.
Where do I find a plan's 2027 Summary of Benefits?
- The plan's website. Look for "plan documents" or "plan materials" and pick plan year 2027. Most companies post a summary for each plan.
- Medicare.gov's Plan Compare. Enter your ZIP code and the plan's details page lays out many of the same cost lines (Plan Compare).
- The enrollment packet, because the rule requires the summary to come with the enrollment form.
- The plan's member services line, which can mail one.
Check the year in the corner. A 2026 summary is easy to find in October and describes coverage that ends December 31. For coverage starting January 1, 2027, you want the 2027 document, chosen during Annual Enrollment, October 15 – December 7, 2026.
What do I check before I open it?
Your doctors and your drugs. The summary prices a "specialist visit" or a "Tier 3 drug" but does not tell you whether your cardiologist is in the network or which tier your inhaler is on. A plan with lovely numbers is no use if your doctors do not take it. So, before reading a single line:
- Doctors and hospital: check each one in the plan's 2027 provider directory, then call the office to confirm. The method is in how to check if your doctor takes a Medicare Advantage plan.
- Prescriptions: enter every drug, dose and pharmacy in Plan Compare, or check the plan's 2027 drug list. Steps are in how to find out what your prescriptions will cost.
Only the plans that pass both checks are worth reading closely. That usually shortens the stack a great deal.
Which lines matter, and what do they mean?
These are the rows you will find on nearly every summary, what each one says, and what to watch for. The last column shows how each line varies across Bernalillo County's 2027 plans, where the CMS plan file reports it.
| Line | What it says | What to watch for | Albuquerque area, 2027 |
|---|---|---|---|
| Monthly plan premium | What the plan charges each month, on top of the Part B premium | The smallest number on the page for most people. Read it last, not first. | $0 on 15 of 19; $20 to $60 on the other 4 |
| Maximum out-of-pocket (MOOP) | The most you pay in a year for covered medical care | On a PPO there are usually two: in-network and combined. Drugs do not count toward it. | $3,800 to $8,000 in-network; middle plan $5,900 |
| Medical deductible | What you pay before the plan shares costs on some services | Often $0 in network. Check whether it applies only out of network. | Not in the CMS file; read each plan's summary |
| Doctor and specialist copays | A flat dollar amount per visit | Look for the word 'referral' and for different amounts in and out of network. | Not in the CMS file; read each plan's summary |
| Hospital stay | Usually a daily copay for a set number of days | Multiply it out. Five days at a daily copay adds up quickly. | Not in the CMS file; read each plan's summary |
| Part D drug deductible | What you pay for drugs before the plan starts sharing costs | Find the line that says which tiers it applies to. Cheap generics are often exempt. | $200 to $700; 12 different amounts |
| Drug tiers | Copay or coinsurance for each tier, by pharmacy type | Tells you the price of a tier, not which tier your drug is on. | Every plan's drug costs stop at $2,400 in 2027 |
Source: CMS CY2027 Landscape file (September 2026 release; linked from CMS, Prescription drug coverage), Bernalillo County, Medicare Advantage plans open to anyone with Medicare that include drug coverage; Special Needs Plans excluded. The file reports premium, in-network maximum and drug deductible; visit and hospital copays are only in each plan's own documents.
The maximum out-of-pocket is the line that protects you in a bad year, which is why we read it first. It caps what you pay for covered medical care, in network, for the calendar year. Two cautions. On a PPO there are often two figures, one for in-network care and a higher "combined" one that includes out-of-network care. Medicare.gov notes that in a PPO you "can generally go to out-of-network providers for covered services, but you'll usually pay more" (Medicare.gov, PPOs). And Part D drug costs do not count toward it; drugs have their own cap.
Copays versus coinsurance: a copay is a flat amount, such as a set fee for a specialist visit. Coinsurance is a percentage, such as 20% of the cost of a piece of equipment. A percentage is harder to predict, so note where the summary uses one. For a hospital stay, plans usually charge a daily copay for a set number of days. Multiply it out to see what a five-day stay would cost.
The premium comes last because it is usually the smallest number. For 2027 in Bernalillo County, 15 of the 19 plans charge no monthly plan premium; you still pay the Part B premium. Why a $0 plan is not the same as a plan with no costs is covered in what's the catch with $0 premium plans?
How do I read the drug section?
Look for three things.
- The deductible amount. For 2027, "no Medicare drug plan may have a deductible more than $700," and some have none (Medicare.gov, Part D costs). In Bernalillo County the 19 plans use 12 different amounts.
- Which tiers the deductible applies to. This is the line people skip. All 19 plans report at least one drug tier with no deductible (CMS CY2027 Landscape file). If your medicines are all low-tier generics, the deductible may never apply to you. If you take a brand-name drug on a higher tier, it probably will.
- The cost for each tier, by pharmacy. Summaries often show a lower price at a "preferred" pharmacy and for a 90-day supply by mail. Check that your pharmacy is the kind the lower price assumes.
One number is the same on every plan: in 2027, once your out-of-pocket spending on covered Part D drugs reaches $2,400, you pay nothing more for covered drugs for the rest of the year (Medicare.gov, Part D costs). That limit is set by Medicare, not by the plan.

How much do these lines differ in Albuquerque for 2027?
Enough to matter. Across the 19 general plans with drug coverage that CMS lists for Bernalillo County in 2027 (Sandoval County's list is the same plans), the in-network maximum runs from $3,800 to $8,000, with the middle plan at $5,900. That is a $4,200 difference in your worst-case year between the lowest and the highest. The drug deductible runs from $200 to $700, and four plans sit at the 2027 maximum. Premiums are the narrowest spread: $0 on 15 plans, and $20, $20, $34 and $60 on the rest (CMS CY2027 Landscape file).
The lesson is that two plans with the same $0 premium can sit thousands of dollars apart on the line that decides a bad year. You only see that by reading past the first row. The full list of plans for the Albuquerque area is in Medicare Advantage plans in Albuquerque for 2027, and how HMO and PPO plans differ on networks and maximums is in HMO vs. PPO in New Mexico.
What does the summary leave out?
By design, quite a lot. It is a summary of the most-used benefits. Things to look for in the Evidence of Coverage or ask the plan about directly:
- Which services need approval first. Many summaries flag that prior authorization may apply. The full rules are in the Evidence of Coverage.
- Referral rules. Whether you need your primary care doctor's referral to see a specialist. This varies by plan type (Medicare.gov, health plan options).
- The fine print on extras. A summary may show "dental" or "hearing aids." Look for whether it is an allowance with a dollar limit, whether it only works with certain providers, and whether it covers the service you actually need.
- Out-of-network costs in detail, beyond the headline percentage.
- Your doctors and your drugs, as above.
If a service you rely on is not on the summary at all, do not assume either way. Look it up in the Medical Benefits Chart in the Evidence of Coverage, or call the plan and ask.
How we use it when we compare
When we compare plans with someone, the summary is the working document, but it is not where we start. We check doctors first, then drugs, then the out-of-pocket maximum, then total yearly cost, and the extras only after that. That is the order on our plan comparison page, and it is the order this article follows. Each autumn we do it again in the annual coverage review, because premiums, drug lists and networks reset every January. There is no charge to you; carriers pay our fee.
We do not offer every plan available in your area, so the summaries we go through with you are for the plans we offer. Every plan in your ZIP code is on Medicare.gov's Plan Compare and through 1-800-MEDICARE, and New Mexico's SHIP program offers free counseling not tied to any insurance company (NM Aging & Long-Term Services Department). Reading the summaries yourself is a good idea whichever route you take. If your 2027 plan is ending, start with your options when Presbyterian Medicare Advantage ends. This page is education, not a recommendation; the choice is yours.

Questions people are asking
What is a Summary of Benefits in Medicare?
It is a short document every Medicare Advantage plan must give people before they enroll, summarizing the most-used benefits and what you pay for each. Federal rules (42 CFR 422.2267) call it "a summary of highly utilized coverage that include benefits and cost sharing," require it to be clear and accurate, and require it to come with the enrollment form, on paper or as a link before you finish an online enrollment. It is a summary, so it is the place to compare plans, not the place to settle exactly what is covered.
What is the difference between a Summary of Benefits and an Evidence of Coverage?
The Summary of Benefits is the short version you read before you enroll. The Evidence of Coverage is the full rulebook. CMS's 2027 model Evidence of Coverage runs to twelve chapters, including a Medical Benefits Chart, two chapters on drug coverage and costs, and a chapter on appeals. If the two ever seem to disagree, or the summary does not mention a service, the Evidence of Coverage is the one to check. Plans must get it to current members by October 15 each year.
Where do I find a plan's Summary of Benefits?
On the plan's website, usually under plan documents for the plan year; in the enrollment packet, since the rules require it to come with the enrollment form; and from the plan's member services line. Medicare.gov's Plan Compare also links to plan details for each plan in your ZIP code. Make sure the document says 2027 if you are choosing coverage that starts January 1, 2027.
Is the Summary of Benefits the same as an Explanation of Benefits?
No. The Summary of Benefits describes a plan before you join it. An Explanation of Benefits (EOB) arrives after you get care and shows what a provider billed, what the plan paid, what you may owe, and how close you are to your out-of-pocket maximum. Plans send EOBs monthly, or per claim with a quarterly summary.
What should I look at first on a Summary of Benefits?
We start with the out-of-pocket maximum, the drug deductible and which drug tiers it applies to, and the copays for the care you use most, such as specialist visits or a hospital stay. The monthly premium comes last. Before any of that, though, check the two things the summary cannot tell you: whether your doctors are in the plan's network and whether your prescriptions are on its drug list.
Does the Summary of Benefits list my doctors and drugs?
No. It shows what a plan charges for a type of visit or a drug tier, not which doctors are in network or which tier your medicine is on. For those you need the plan's provider directory and its formulary (drug list), or Medicare.gov's Plan Compare with your drugs entered. The summary usually tells you where to find both.
