The Plan column says what the plan printed in its own provider directory (MMM, June 2026 · MCS Advantage, August 2026 · Triple-S Advantage, September 2025 · Plan Vital / First Medical, August 2026), not whether they will take you. A dash 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 a dash almost always means that row could not be matched.

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 oncólogo / hematólogos 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.
