Nefrólogo (riñón) · Cabo Rojo · Oeste
MMM lists this provider in its provider directory of June 2026.
That is what the 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.
MMM publishes another number for this office: 787-832-2640. If the one above does not answer, try that one.
See the MMM directory (PDF) → · Where this cross-check comes from: the MMM audit
These 2 blocks say what the 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 the Plan Vital directory rows and 52% of MMM's, so it almost always means that row could not be matched. 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 nefrólogo (riñón)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.
