WhatsApp for Hospitals: OPD Booking, Report Alerts & Patient Support

This guide covers the hospital-scale part: many departments, many staff, one number. Running a single clinic? Start with our WhatsApp guide for clinics, or see WhatsApp for clinics, labs and hospitals. Every scenario below is an example setup, not a customer story.

Top hospital WhatsApp use cases

Use case	Mark360 feature	Template category	Example trigger
OPD timings, doctor roster, fees	AI agent + knowledge base	Service (free-form, inside 24h)	Patient messages first
Book an OPD slot	AI agent (Appointment Booking) + appointment calendar	Service	Patient types "appointment"
Pre-visit intake	WhatsApp Form with a document picker	Utility (template button)	Booking confirmed
Appointment reminders	Drip: Appointment Reminder	Utility	24 hours before, and the same morning
Department routing	Team inbox: teams, round-robin, permissions	Service	Patient picks a department
Report ready	Utility template from the API or a workflow	Utility (secure link only)	Report signed off in the lab system
Follow-up visit due	Custom drip on a follow-up date field	Utility	3 days before the date
Feedback after the visit	Drip: Review Collection + feedback Form	Utility or marketing (Meta decides)	2 days after the OPD visit or discharge
Health-check packages	Broadcast to a dynamic group	Marketing (opted-in only)	A health day or the season

"Service" means a free-form reply inside the 24-hour window that opens when the patient messages you. Outside it you need a Meta-approved template.

Why hospitals gain from WhatsApp and Instagram automation

A hospital front desk answers the same questions all day: which doctor sits when, what the fee is, where the report is. It's logistics, not medicine, and it arrives by phone and on staff members' personal WhatsApp.

• Volume needs a system. One official number with a shared inbox means no chat is lost at a shift change.
• Departments need their own queue. A billing question shouldn't wait behind a cardiology booking.
• Patients ask after hours. An AI agent answers logistics at night; staff handle clinical questions.
• Package enquiries start on Instagram. Mark360.ai's Instagram automation can DM the package brochure to anyone who comments on a health-check reel and ask for their WhatsApp number.

AI agent for hospitals: what it answers and when it hands off

A WhatsApp AI agent on Mark360.ai answers from the knowledge base you upload, in English and Hindi, and hands off to a person in the team inbox. Use the Appointment Booking template for OPD slots (bookings land in the appointment calendar) and General Support for other questions.

• It answers: OPD timings, the department-wise doctor roster, consultation fees, booking and rescheduling, documents to bring, directions, visiting hours and the health-check package list.
• It never answers: symptoms, medicines, doses, results or "is this serious?". It says a doctor needs to see this and offers the next OPD slot.
• It hands off to the team inbox: clinical questions, complaints, billing or insurance disputes, requests for a person, and anything that sounds like an emergency, after first giving the emergency number.

Example: a multi-speciality hospital in Nagpur gets a message at 10:40 pm asking if the orthopaedic doctor sits on Saturday. The agent reads the roster, gives the OPD timing and offers two slots; the booking is on the calendar before the OPD opens.

How to set up a hospital AI agent in Mark360.ai

1. Go to AI Agents and pick the Appointment Booking template.
2. In "Agent Role & Instructions", list what it answers and what it must hand off: clinical questions, complaints, billing disputes and emergencies.
3. Upload the knowledge base: doctor roster, OPD timings, fees, packages and directions. Update it when the roster changes.
4. Test in the phone preview, then switch it on.
5. Add keyword triggers for "appointment", "OPD", "doctor" and "book".

Example chat (service replies inside the 24-hour window)
Patient: Is the orthopaedic doctor available on Saturday?
Agent:   Yes. Orthopaedics OPD runs on Saturday from 10 am to 1 pm.
         Shall I book a slot? 10:30 am or 11:15 am?
Patient: 11:15. Also my knee is swollen since yesterday, what
         medicine should I take?
Agent:   Your 11:15 am slot is booked. I can't advise on medicines.
         I'm passing your question to our Orthopaedics team now.
         If the pain is severe, please call our emergency number.

Plan note: the AI support agent is on Scale+ ($99/mo); the no-code chatbot builder starts on the Free plan. More in our WhatsApp AI agent guide.

WhatsApp Forms for OPD booking, intake and feedback

WhatsApp Forms (Flows) are multi-screen forms inside WhatsApp, with text, date, dropdown, choice, opt-in, photo and document inputs. You can launch one from a template button, a bot or an automation, and every submission is listed per Form with a date filter and export.

Example: a hospital runs three Forms: OPD booking (department, doctor or "any available", date, first visit or follow-up), pre-visit intake (name, age, payment mode and an optional upload of an old prescription) and feedback (ratings for the doctor, nursing and billing, plus a comment).

How to build the intake Form

1. Create a Form with three screens: "Patient details", "Visit" and "Documents".
2. Add text and date fields, a department dropdown and a document picker.
3. Add an opt-in field ("Send me hospital updates on WhatsApp") and keep it unticked by default.
4. Attach the Form to the booking confirmation template as a button, then publish.

Guardrail: collect only what the front desk needs, follow local health-data rules (in India, the Digital Personal Data Protection Act, 2023) and don't ask for symptoms. The Scale plan includes 2 Forms.

Team inbox for hospitals: department routing on one WhatsApp number

The shared team inbox puts WhatsApp and Instagram DMs in one list (Unassigned, Mine, Pinned, Resolved) with team rules, round-robin, internal notes, working hours and an away reply. Each agent has about 50 module permissions, including a separate View Unassigned Chats permission.

Example: a hospital creates five teams: Front desk, Cardiology, Orthopaedics, Billing & insurance and Health checks. A welcome bot asks which department the patient needs, team rules send the chat there, and round-robin spreads it across coordinators on shift. Only the front desk sees unassigned chats.

How to set up department routing

1. Create the teams and add agents to each.
2. Turn off View Unassigned Chats for department staff.
3. Build a welcome bot with a department choice and team rules for each answer.
4. Turn on round-robin so new chats spread across available agents.
5. Set OPD hours, holiday mode and an away reply.

Away reply (service, after OPD hours)
Our OPD desk is closed now and opens at 8 am. For a medical
emergency, call {{emergency number}} or go to the nearest
emergency department. Don't wait for a WhatsApp reply.

Internal notes and @mentions bring in a coordinator without the patient seeing it. For several branches, make one team per branch and department. See how several agents share one WhatsApp number.

Appointment reminder drip: the actual sequence and timing

A WhatsApp drip sends approved templates timed from each patient's own event, with start and stop conditions, sending days and a time window.

1. OPD appointment (Appointment Reminder preset, starts when a booking is made):

• Straight away: confirmation with doctor, date and time, plus the intake Form button.
• 24 hours before: reminder with "Confirm" and "Reschedule" buttons.
• Same morning, 7 am (or 3 hours before an afternoon OPD): directions, which floor or counter, and what to bring.
• Stop conditions: the tag "cancelled", the tag "rescheduled" (the new booking starts a fresh sequence) or an opt-out.

2. Follow-up visit (a custom sequence on a "follow-up date" field the doctor's desk fills): 3 days before at 10 am, 1 day before at 6 pm, and 2 days after if still unbooked. It stops on the tag "follow-up booked".

Category: UTILITY   Name: opd_appointment_reminder
Hi {{1}}, a reminder of your OPD appointment with {{2}} ({{3}})
at {{4}} on {{5}} at {{6}}. Please bring a photo ID and any
old prescriptions or reports.
[Button: Confirm]   [Button: Reschedule]   [Button: Get directions]

Utility or marketing? It's about a booked appointment with no offer, so it's utility. Add a package discount and it becomes marketing. See our appointment-tomorrow template and other appointment reminder templates.

Report-ready alerts on WhatsApp: a secure link, never the diagnosis

Patients want to know when a report is ready, not to read the result in a chat. Send a utility template with a link to your secure patient portal and keep every result and diagnosis out of the message.

Example: when the lab system marks a report as signed off, it calls the Mark360.ai API with a token limited to the send_templates scope, and the approved template goes to the patient's registered number. Without that connection, staff send it from the inbox.

Category: UTILITY   Name: report_ready_secure_link
Hi {{1}}, your report for the test done on {{2}} at {{3}} is
ready. View it on our secure patient portal: {{4}}
For questions about the report, please book a consultation.
[Button: View report]   [Button: Book a consultation]

Start from our lab report ready template and the full healthcare template library.

Health-check broadcasts and Click-to-WhatsApp ads (opted-in only)

A WhatsApp broadcast sends one approved template through a 4-step wizard (template, groups, map fields, send or schedule) to dynamic groups built from tags and custom fields, and shows delivery, read and failure rates. It goes only to opted-in contacts.

Example: before World Heart Day, a cardiac health-check announcement goes to the dynamic group "opted in, age 40+".

Category: MARKETING   Name: health_check_package
Hi {{1}}, {{2}} now offers a {{3}} health check package,
available till {{4}}. Pick a date and book in a few taps.
[Button: See packages]   [Button: Stop offers]

It's marketing, so it needs opt-in and an opt-out keyword. See our annual check-up package template.

Click-to-WhatsApp ads: a Click-to-WhatsApp ad for a package opens a chat with your number; a bot replies first and round-robin assigns it to the Health checks team. The ad itself is built in Meta Ads Manager. If you reply within the service window to someone who came from the ad on the mobile app, Meta's pricing rules open a free entry point window of up to 7 days in which Meta doesn't charge for your messages. Check each message's price in Transaction History. More in our Click-to-WhatsApp ads guide.

Integrations hospitals actually use

• Google Sheets: sync patient contacts and the follow-up date from the OPD register sheet.
• Razorpay payment links: for a health-check package or teleconsultation fee, tracked as paid, pending or failed.
• Zoho CRM: package and international-patient enquiries become Zoho CRM leads, with duplicate detection on the phone number.
• API tokens and webhooks: your hospital or lab system can send approved templates and receive message events.

A complete hospital WhatsApp journey (sample automation flow)

1. Capture: an OPD WhatsApp QR code, the website chat widget or a Click-to-WhatsApp ad.
2. Book: the AI agent answers and books the OPD slot.
3. Intake: the confirmation opens the intake Form.
4. Remind: 24-hour and same-morning reminders.
5. Route: questions the agent can't answer go to the right department team.
6. Report ready: a utility alert with a secure link.
7. Follow up: the follow-up drip runs from the doctor's date.
8. Feedback: the feedback Form goes out 2 days after the visit.

Workflow nodes: entry when a contact joins the group "OPD visit completed" → delay (2 days) → WhatsApp form (feedback) → wait-for-event (form submitted) → condition (rating 2 or lower?) → WhatsApp message (apology and hand-off). Stop: the Form is submitted, or the patient opts out.

How much does WhatsApp cost for a hospital?

On Mark360.ai in India, a marketing message is ₹0.94 and a utility message ₹0.138. Since 1 October 2026 each number gets 1,000 free service messages a month. Plans: Free $0, Scale $19/mo billed quarterly, Scale+ $99/mo, Enterprise custom (pricing).

Example arithmetic, not a forecast: 2,500 utility messages (booking confirmations, reminders and report-ready alerts) × ₹0.138 = ₹345.00, plus 800 marketing messages × ₹0.94 = ₹752.00, makes ₹1,097.00 in messages a month, plus your plan. Compare it with your own front-desk hours spent on reminder calls. Try the pricing calculator or read WhatsApp API pricing in India.

Compliance checklist for hospital WhatsApp

• Opt-in first: collect it at registration, with an OPD QR code or in a Form opt-in field, as WhatsApp's Business Messaging Policy requires.
• No diagnosis in messages: report alerts carry a secure link; results stay in the portal.
• Match the category: a reminder with a package offer is marketing (templates guide).
• Honour opt-outs with a STOP keyword; it removes the patient from future campaigns.
• No prescription-drug or medical-product selling on WhatsApp; promote services and packages only.
• Limit staff access with per-agent permissions. Mark360.ai doesn't claim HIPAA or any other certification; check your own legal requirements.
• Protect your quality rating (why numbers get banned).

Summary: hospital WhatsApp in one paragraph

A hospital WhatsApp setup is one official WhatsApp Business API number shared by every department. An AI agent answers logistics and books OPD slots, WhatsApp Forms collect intake and feedback, drips send utility reminders, team rules route chats to departments, report-ready alerts carry a secure link instead of results, and health-check offers go only to opted-in patients.
