Frequently Asked Questions

An AI-powered doctor answering service takes patient calls on behalf of a medical practice, using artificial intelligence to listen, understand, and respond in real time. Instead of a traditional call center or voicemail box, the AI can handle routine scheduling, rescheduling, and basic questions automatically.

For patients, that means they don’t have to wait on hold or call back during office hours — they get an immediate response any time of day. For practices, it means fewer missed calls, reduced administrative burden for staff, and a smoother flow of appointments into the calendar.

Using natural language technology, Zo listens to what the patient says — whether it’s “I need to book a new appointment,” “Can I reschedule?” or “What’s the address?” — and interprets the request in plain English (or other supported languages). And because Zo is connected directly to the practice’s Zocdoc calendar, it can offer real-time appointment options, confirm bookings, move or cancel visits, and send confirmation messages automatically. For questions outside of scheduling (like prescription refills or urgent clinical issues), Zo can route the call to the right staff or provide instructions.

Absolutely. Whether you’re a cardiologist, pediatrician, or have a multi-location practice, the system can be tailored to match your provider schedule, patient types, and care offerings.

It can manage appointment scheduling, cancellations, general inquiries (e.g., address, insurance, referral requirements), prescription refill requests, emergency screening, and message routing to the appropriate staff.

Absolutely. The service provides round-the-clock support—handling overflow during busy hours and covering nights, weekends, and holidays, so no patient call goes unheard.

Yes. All calls are logged, and transcripts or summaries can be reviewed to ensure quality, compliance, and continuity of care. You’ll always have visibility into patient interactions, even when handled by the AI.

The system is trained to recognize context clues and specific phrases that indicate urgency or complex needs. When that happens, it routes the call based on your custom escalation settings—whether that means forwarding to a specific line, paging an on-call provider, or leaving a flagged message for follow-up.
