AI Receptionist vs Medical Answering Service: Cost Comparison
How AI receptionists and traditional medical answering services compare on cost, what each one actually does, and how to work out the right choice for your practice.

Introduction
For years, the only way to cover calls after hours was a medical answering service: a team of operators who take a message and pass it on. AI receptionists now do the same job and more, often for less.
This guide compares the two honestly, including the cases where an answering service is still the better choice.
Key takeaways
- Answering services usually take messages; AI receptionists can answer questions and book the appointment.
- Answering services often charge per minute or per call on top of a monthly base.
- Clinic24 costs from $29 a month for 150 minutes, about 19 cents a minute.
- Practices with clinical triage needs may still want a nurse line alongside AI.
1. What each option actually does
Medical answering service: a live operator answers, takes the caller's details and a message, and sends it to your team or on-call provider. Someone at the practice still has to call back and book.
AI receptionist: answers instantly, answers common questions from your FAQ, checks your calendar and books the appointment. Your team gets a summary and recording of each call.
2. How the pricing works
Answering services use different models: a monthly base with included minutes, per-minute billing, or per-call billing, often with extra fees for holidays, patching calls or setup. Ask for a full quote based on your real call volume.
Clinic24 uses simple plans:
- Standard: $29/month for 150 minutes (about 60 calls), roughly $0.19 a minute
- Pro: $79/month for 300 minutes (about 120 calls), roughly $0.26 a minute, with 5 concurrent calls
- Top-up: $10 for 50 extra minutes, no contract
3. Work out your own numbers
Take last month's missed and after-hours calls from your phone system. Multiply by your average call length to get minutes. Then compare what each option would cost for those minutes, and how many of those calls would become booked visits instead of messages.

4. When an answering service still makes sense
If your practice needs a person to make clinical judgements after hours, such as nurse triage or paging an on-call physician, keep that service for those calls. Many practices use AI for booking and routine questions and route clinical calls to their existing on-call process.
5. The bottom line
For most independent practices, the biggest cost is not the service fee but the new patients lost to voicemail. An AI receptionist for US practices books those callers while they are still on the phone.
