Heads up if you have MMM: this provider appeared in the December 2025 directory and no longer appears in the June 2026.
They may have left the network. Confirm with MMM before booking, or you could end up paying out of pocket.
Not the only one: 254 providers left the MMM directory in the last 6 measured months, and all 511 who left are still active in the federal registry. The network clock →

Triple-S Advantage lists this provider in its provider directory 2026 · Medicos Primarios · under Fajardo.
The plan last updated that directory on September 9, 2025. It is what they published, not a confirmation that they will take you.
Plan Vital (First Medical) lists this provider in its July 2026 · Grupo Médico Primario y Red Preferida de Proveedores · under Fajardo · page 108 of the PDF.
That is what the plan published, not a confirmation that they will take you.
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.

📞 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 internista (medicina interna)s 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.
