Medical Office Answering Service: 6 Options (2026)
The phones open at 8, and by 8:05 every line is lit. At 6pm the office closes and the calls keep coming: a refill, a fever, a patient who needs Thursday moved. A medical office answering service takes those calls so nobody hears voicemail.
The quick answer: You have three kinds of option. A live medical answering service (PatientCalls, AnswerFirst) has trained operators take messages and page your on-call provider. Healthcare AI vendors (Hello Patient, Assort Health, Weave) answer and schedule inside larger systems after a demo and an implementation. Or an AI receptionist like Carly answers your number the same day, books patients on your providers’ schedules during the call, sends urgent calls to a person and texts the on-call provider a summary. Carly signs a Business Associate Agreement on Enterprise plans.
What a medical office answering service has to do
- Sort every call into urgent (to the on-call provider now), emergency (tell the caller to hang up and dial 911), routine (book, reschedule, refill request) and message for the morning.
- Reach the on-call provider with the patient’s name, callback number and the reason for the call, then confirm it was received.
- Book the routine calls instead of leaving a stack of callbacks for 8am.
- Protect patient information. Under HIPAA, a vendor that handles patient information for your practice is a business associate and needs a signed business associate agreement.
- Never give medical advice. The service follows your clinical routing rules and leaves the medicine to your clinicians.

1. Carly
Carly runs your practice’s calls, texts and email in one place. It’s reliable and endlessly customizable: write the rules in plain English (“refill requests go to the nurse line, chest pain is told to call 911, new Medicare patients see Dr. Thompson, never give medical advice”) and it follows them on every call.
Setup takes minutes. Paste Carly’s setup prompt into ChatGPT or Claude and it builds the receptionist, phone number included. Keep your practice number and forward the calls you miss, or forward everything after hours.
- Answers every line at once, whether that’s the Monday rush, lunch or 2am.
- Books during the call through your scheduling system’s API where it has one, or on your providers’ Google or Outlook calendars, so patients hang up with a time.
- Reaches the on-call provider. Urgent calls get put through, and a workflow texts the on-call provider the patient’s name, number and reason the moment the call ends.
- Handles the routine. Reschedules, cancellations, directions, which insurance you take and “is my form ready?”
- Texts from your practice number: confirmations, reminders the day before and a text back on every missed call (automated appointment reminders).
- Speaks English and Spanish, picked from how the patient talks (bilingual answering).
- Hands the morning team one inbox. Every call, recording, transcript and text in one place and in Carly’s CRM.
- Connects to everything. Carly connects to thousands of apps, so a booked call can alert a provider in Slack or Teams and create a follow-up task.
HIPAA: Carly signs a Business Associate Agreement on Enterprise plans. Book a call to set one up.
Best for: independent practices and growing groups that want calls answered and booked without a months-long rollout. Get started.
2. PatientCalls
PatientCalls is a HIPAA-compliant medical answering service that triages patient calls to your on-call staff 24 hours a day, for doctors, home care and hospitals. Its PatientNote app for secure messages is included, and it says it connects to most EMR systems through an API.
- Watch for: demo-led, and operators take messages more than they book.
- Best for: practices that want a person on every after-hours call.
3. AnswerFirst
AnswerFirst runs a HIPAA-compliant medical answering service with US-based operators, 24/7 coverage and appointment setting.
- Watch for: pricing is by quote, and script changes go through the vendor.
- Best for: practices that want trained people answering.
4. Hello Patient
Hello Patient runs AI agents on calls, texts and chat for “high-volume healthcare,” with 24/7 scheduling, insurance checks up front, no-show follow-up and recall outreach.
- Watch for: pitched at large groups (its featured customer is a 96-location urgent care chain).
- Best for: multi-location groups drowning in calls. More in our AI medical receptionist ranking.
5. Assort Health
Assort builds healthcare voice agents for scheduling, routing and triage, intake and referrals, and says it has handled more than 300 million patient interactions.
- Watch for: a demo and an implementation first; a small practice is a lot of product for the job.
- Best for: large specialty groups with complex scheduling rules.
6. Weave AI Receptionist
Weave sells phones, texting, forms and payments to practices, and its AI receptionist answers calls and texts around the clock.
- Watch for: Weave’s page says direct booking works on “qualified Dental PMS only,” so a medical office gets a request its team schedules later.
- Best for: offices already on Weave that mostly want messages taken.
How to pick a medical office answering service
- Will it sign a BAA? Ask before any patient call goes through it. Carly signs one on Enterprise plans.
- Does the call end with a booking or a message? A message is a callback your staff still makes. If you want patients booked on the call, go with Carly.
- How does it reach the on-call provider, and how fast? Have the vendor walk you through a 2am call.
- Can you change the routing yourself? With Carly you type the change; with live services you rewrite a script.
- How long until it answers a real call? Enterprise AI starts with an implementation. Carly answers the same day.
Set it up in minutes
Carly business setup prompt
Paste this into ChatGPT, Claude or any AI. It walks you through the rest.
Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.
# Connect Carly Teams to an AI app
> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.
MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)
## Setup
Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.
1. Add Carly Teams:
- ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
- Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
- Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
- Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
- Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
- Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
Sign in with the Carly account that belongs to the organization.
2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.
3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.
4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.
## Email, calendars and workflows
Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.Then tell it when to answer (overflow, lunch, after hours or every call), how to book each visit type and who’s on call, and ring it from your cell to test it (build-and-test tutorial). For the rest of the front office, see AI tools for medical practices and our after-hours answering service guide.
FAQ
What is a physician answering service?
A service that answers a practice’s calls when staff can’t, usually after hours, and routes urgent calls to the on-call physician. Live services take messages and page the provider; an AI receptionist like Carly also books routine visits during the call.
Does a medical answering service need to be HIPAA compliant?
Yes, if it handles patient information for your practice. It counts as a business associate under HIPAA and should sign a business associate agreement. Carly signs a BAA on Enterprise plans.
How does an answering service reach the doctor on call?
It depends on the service: a page, a text, a transferred call or a secure app message. Carly puts urgent calls through and texts the on-call provider a summary as soon as the call ends, following the rules you write.
Can an AI answering service handle a medical emergency?
It follows your rules. A common setup tells callers with emergency symptoms to hang up and call 911, then texts the on-call provider. Tell Carly never to give medical advice, and it follows that on every call.
Can I keep my practice phone number?
Yes. Forward the calls you miss, or everything after hours, to Carly. Live services also work by forwarding your number.
Ready to automate your busywork?
Carly schedules, researches, and briefs you—so you can focus on what matters.
See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
