📞 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.
💚 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 alergista / inmunólogos 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.
