Listed in these plans' directories
- MCS Advantage updated Aug 10, 2026 · Primario · under San Juan
That is what each plan published, not a confirmation that they will take you. Before you go, call and ask whether they take your plan and whether they are accepting new patients.
Why "listed in the directory" is not "they take your plan"?
These blocks say what each plan printed in its directory, not whether they will take you. And a plan missing here does NOT mean the provider is out of that network: the federal-number cross-check identifies 33% of Plan Vital directory rows, 51% of Triple-S Advantage's and 52% of MMM's, so it almost always means that row could not be matched. Note the dates too: these directories are not published on the same day, so one may be more current than another. Before switching plans, confirm with the office.
What 2 sources independent of the plan say
Treated Medicare patients: 84 Part D prescriptions in 2024, per CMS. A sign of an active practice, not of quality or that they will take you.

Did you call? Help the next person
Tap the plans they told you they accept. 5 seconds. This is how the whole town fills the answer nobody else has.
Did they tell you if they are taking new patients?
Is this for your mom or dad?
Send it ready to go: name, specialty, phone, and the reminder to confirm the plan. One tap.
Before you call, have this ready
Two minutes of prep save you weeks of back and forth.
- ✓Have your plan card and ID at hand. The first thing they ask. If it is for a relative, also their date of birth and plan number.
- ✓Ask your primary doctor for the referral first. Many médico generalistas will not book you without one. Request it by phone, do not wait for your next visit.
- ✓Ask these two questions first. "Do you accept my plan?" and "Are you taking new patients?" That saves you the whole trip.
- ✓Ask how long the wait is, and to be put on the cancellation list. Someone cancels almost every week. Whoever is on the list gets that slot.
- ✓Write down who you spoke with and the date. If anything gets tangled later, that note untangles it.
