Patient self-service on WhatsApp gives a patient five things from the hospital's WhatsApp number without an app, a login or a phone call: book an appointment, see which token each doctor is currently serving and how many people are waiting, check their own queue number and estimated wait, manage their follow-up appointments, and reach the hospital's phone numbers for anything else. It starts with a QR code at reception, works in English and Hindi, and deliberately does not answer medical questions.
This guide explains the patient's side of Healthixio's WhatsApp bot — what each option does, the limits that keep it safe and free, and what it changes in the waiting room.
Getting started: the QR at reception
The HMS prints a poster with a WhatsApp QR code that opens a chat with the hospital's number and a pre-filled first message containing the hospital's code. The patient scans it once — at reception, on the website, on the appointment card — and from that first message their number is linked to the hospital. Returning patients are recognised; a stranger who messages without the code gets no reply, which is what keeps the number from being spammed.
The five things a patient can do
1. Book an appointment
The patient picks a doctor from the list, then gives their name, age, gender and address. The appointment is booked on the OPD register and the reply carries the token number, the time and the doctor, with a note to pay at the hospital. Self-booking is capped at two appointments per number per hospital per day — front-desk bookings for that number count too — and beyond that the bot hands over the hospital's phone numbers rather than let one phone fill the register.
2. Current token
Which token each doctor is serving right now and how many patients are waiting — read from the same data as the waiting-room display board. The patient currently in the consulting room is deliberately not named.
3. My queue number
The patient's own token, doctor and time, how many patients are ahead of them, and an estimated wait at roughly ten minutes per patient. When nobody is ahead the message says "You are next". This is the option that lets a patient wait in the car, the canteen or at home instead of on a bench.
4. My appointments
Upcoming follow-ups, each with Confirm, Reschedule and Cancel buttons — the same buttons that arrive on the 7 PM reminder the evening before. Reschedule accepts a typed date such as "25-08-2026", "20 Aug" or just a day of the month. Cancel marks the appointment cancelled so the front desk sees it and the slot is reused.
5. Other query
The hospital's phone numbers. That is the whole hand-off, on purpose: a patient with a medical question, a billing dispute or an emergency should reach a person, not a chatbot.
What it deliberately does not do
- It does not answer medical questions or give advice.
- It does not show bills or take payments.
- It does not free-text chat. Unrecognised input re-prompts a few times and then goes quiet.
- It does not reply to numbers that have not been linked to the hospital.
Those limits are why the bot is safe to put on a poster in a public reception area, and why it costs the hospital nothing to run.
What it costs
Every one of the five options is a reply to a message the patient sent, which under Meta's rules is a free service message inside the 24-hour window the patient opened. From 1 October 2026 Meta allows 1,000 such messages per business number per month before charging at the utility rate — about ₹0.115 — which still leaves a busy OPD's bill in the tens of rupees. The only paid message in the patient's journey is the evening-before reminder. See WhatsApp cost for hospitals.
What changes in the waiting room
- Fewer bodies on benches. Patients who can see they are number 22 of 30 wait elsewhere and come when they are three away.
- Fewer calls to reception asking "is the doctor in" and "what number are you on".
- Fewer no-shows, because confirm and cancel are one tap. See WhatsApp appointment booking and reminders.
- A booking channel that never closes, without a call-centre or a website form.
- A WhatsApp contact on Google Maps that does something. A patient who taps the number from your profile can book, not just ask. See how patients find hospitals in 2026.
Privacy
The bot shows a patient only their own appointments and queue position; the live token view names no one. Numbers are linked to a hospital by the patient's own first message and can be unlinked on request. The hospital is the data fiduciary under the DPDP Act, and consent for WhatsApp communication is captured at registration. See our DPDP timeline for hospitals.
Frequently Asked Questions
Can patients book hospital appointments on WhatsApp?
Yes. After scanning the hospital's QR once, a patient picks a doctor, gives their details and receives a token on the OPD register — no app or login. Healthixio caps self-booking at two appointments per number per day.
Can a patient check the OPD queue on WhatsApp?
Yes. Current Token shows which number each doctor is serving and how many are waiting; My Queue Number shows the patient's own position and an estimated wait. Both read the same data as the waiting-room display.
Does the WhatsApp bot answer medical questions?
No. Anything outside booking, queue and appointment management returns the hospital's phone numbers so a person answers. This is deliberate for patient safety.
Does the bot work in Hindi?
Yes. Every patient-facing message is written in English and Hindi together. Button labels stay in English because of WhatsApp's character limits.
