# Two Medicare clinics. Only one says Medicare. https://getclinads.com/market-research/oak-street-vs-centerwell-senior-primary-care Can AI find a Medicare doctor that takes your plan? Oak Street answers almost everything. CenterWell never says the word.

A senior types medicare doctor near me that takes humana. Two senior primary care chains want that visit: Oak Street Health, with 231 clinic pages, and CenterWell, with 195.

Read the way an AI assistant reads them, Oak Street answers almost every question a patient has. CenterWell never once says the word the patient searched for: Medicare.

Search for a Medicare doctor that takes Humana: an Oak Street clinic page carries address, hours and a map pin in code and names Humana and Aetna; a CenterWell center page has address and phone in words, no plan named and no machine-readable data
Two Medicare clinics. Only one says Medicare.

Five questions: Oak Street answers five, CenterWell two

Oak Street hands a machine the address, the hours and the plans

Every Oak Street clinic page we sampled carries a full clinic listing written for machines. It even lists the insurers in code, next to a rating and a FAQ.

An Oak Street clinic page carries a MedicalClinic listing with street address, coordinates, opening hours and the insurers it accepts
The address, the hours and the plans, all in the data.

Then ask Oak Street’s finder for a clinic. It shows none.

The clinic list on the locations, state and city pages loads with JavaScript. In the raw page a crawler receives, there is a search box and a “Loading” placeholder, and no clinic.

The best clinic pages in this teardown sit behind a finder that hides them. An assistant browsing from the city page never reaches one.

Oak Street's locations, state and city pages show a search box and a loading placeholder but no link to any clinic before JavaScript runs
Great clinic pages, behind a door only JavaScript opens.

CenterWell prints the basics and links every center

Each center page says the address, the phone and the week’s hours in plain words, with a directions link. And one plain HTML page links all 195 centers, which Oak Street’s finder never does.

The easy part, done everywhere.

CenterWell says it in words, but never “Medicare”

Not once, on any of the 60 center pages, in the text a crawler reads. The plan list sits behind a “See accepted plans” button, packed inside 1.3 MB of script. And there is no page data at all: no clinic listing, no address, no coordinates, no hours, no plans.

0 / 60center pages that say “Medicare”, and 0 that name a single insurer, not even Humana, which owns CenterWell
1.4 MBof page to deliver about 2,400 characters a reader can see. Oak Street: 201 KB for 13,900

Every center page also ships without a meta description or link preview tags, so a center pasted into a chat arrives as a bare URL.

CenterWell center pages carry no structured data, never say Medicare, name no insurer and weigh 1.4 MB for about 2,400 visible characters
The word a senior searches for, missing from every page.

The scorecard: eight checks to three, and the ninth goes the other way

Nine checks, the same method, both chains.

Why this matters to a clinic

Oak Street did the hard part: a near-complete clinic page, then hid it behind a finder only JavaScript can open. CenterWell did the easy one: it links every center in plain HTML, then never says what a senior is searching for, Medicare and the plan they carry.

For a web team, each fix is a few days of work. For a single clinic, both fit in an afternoon: say which plans you take in words a crawler can read, and make sure a plain link leads to your page.
