The “Reschedule” Reality: Important Notice
Many patients look for a single “Reschedule” button on the portal. It does not exist. To change your date, you must follow the “Cancel & Rebook” protocol. Because AIIMS Delhi slots are the most competitive in India, you must be strategic: Always check for new slot availability before you cancel your current one. Once you click cancel, that slot is instantly released to the public and cannot be reclaimed.
Step-by-Step: How to Change Your AIIMS Appointment
Step 1: Check New Slot Availability First
-
Visit the official ORS Patient Portal at ors.gov.in.
-
Click “Book Appointment” → Select Delhi → AIIMS, New Delhi.
-
Choose your specific Department (e.g., Cardiology, Neurology).
-
The Calendar Check: * Green Dates: Slots available. Proceed to Step 2.
-
Red/Grey Dates: No slots. Do not cancel your current appointment unless you are okay with not seeing a doctor at all this month.
-
Step 2: Cancel Your Existing Appointment
If you found an available date:
-
Go to the “Manage Appointment” section on the ORS portal or e-Hospital app.
-
Login using your Aadhaar-linked Mobile Number or ABHA ID.
-
Select your active AIIMS Delhi booking and click “Cancel.”
-
Verify the cancellation via the OTP sent to your phone. You will receive an SMS confirmation.
Step 3: Book the Fresh Appointment Immediately
-
Immediately return to the booking page.
-
Select your new date and confirm.
-
Note: Your UHID (Unique Health ID) stays the same, but you will get a brand new Appointment ID.
3 Pro-Tips for 2026 SEO & Patient Success
-
The “8:30 AM Rule”: If you need to reschedule for a very popular department (like Gastroenterology), log in at 8:25 AM. Refresh the page exactly at 8:30 AM when the system releases the new day’s quota.
-
The ABHA Advantage: Ensure your ABHA ID is linked. In 2026, AIIMS uses this to auto-verify your follow-up status, making the re-booking process 3x faster than manual entry.
-
Teleconsultation (The “Stay Home” Alternative): If you can’t travel to Ansari Nagar but need a report reviewed, check if your department offers eSanjeevani Teleconsultation. You can often convert a physical visit to a video call without losing your spot.
Important Warning
If your appointment date has already passed, the system will mark it as a “No-Show.” You cannot reschedule or cancel a past date. You will have to start the booking process from scratch as a “returning patient.”
