Patients planning to visit the All India Institute of Medical Sciences (AIIMS) can book OPD appointments online for many departments through the government’s Online Registration System (ORS). Instead of depending only on hospital registration counters, patients can use ors.gov.in to select a participating hospital, choose an OPD department, check available appointment dates and complete registration using a mobile number or ABHA.
The same ORS system also provides access to services such as OPD appointment slips and lab reports where the selected hospital has enabled them. However, appointment availability is controlled by each hospital, so the departments, dates and number of online slots can differ from one AIIMS to another.
For a new patient, the most important things are the correct AIIMS hospital, the department you need to visit, an active mobile number and your patient details. Existing patients may also need their previous UHID, hospital registration details or ABHA-linked records, depending on the hospital and appointment type.
This AIIMS OPD appointment guide for 2026 covers online registration, new and follow-up appointments, appointment slips, documents, offline registration, AIIMS Delhi OPD timings, appointment fees, lab reports and common booking problems.
AIIMS OPD Appointment 2026: Important Details for Patients
AIIMS appointment rules are not identical at every institute. A common mistake is assuming that the OPD timing, fee or booking window shown for AIIMS Delhi automatically applies to AIIMS Patna, Bhopal, Rishikesh, Raipur or another branch.
The most useful 2026 information to understand before booking is summarized below.
| AIIMS OPD Booking Detail | Information |
|---|---|
| Main online booking system | Online Registration System (ORS) |
| ORS website | https://ors.gov.in/ |
| Main service | Government hospital OPD registration and appointment booking |
| Patient verification | Mobile number and/or ABHA, depending on the booking flow |
| New patient booking | Available for participating hospitals and departments |
| Follow-up booking | Availability depends on hospital and department |
| Appointment confirmation | Usually generated after successful OTP verification |
| OPD slip | Can be downloaded or printed when provided through ORS |
| Offline registration | Available through hospital appointment/registration counters |
| Lab reports | Online access is available for participating hospitals |
| Emergency treatment | Emergency patients should use the hospital emergency service rather than routine OPD booking |
| OPD fee | Depends on the AIIMS institute and service |
The key point is that ORS provides the booking framework, while the individual AIIMS hospital controls its departments, appointment quota and available dates. ORS itself confirms that hospitals determine the quota offered through the web and hospital counters.
What Is the AIIMS ORS Online Registration System?
The Online Registration System (ORS) is a government platform that connects participating hospitals with an online OPD registration and appointment system. It is hosted using National Informatics Centre infrastructure and integrates with hospital management systems to make registration easier for patients.
For AIIMS patients, ORS can be used to handle several important parts of an OPD visit without first travelling to the hospital.
Depending on the selected AIIMS and available services, patients may be able to:
- Book a new AIIMS OPD appointment
- Select a hospital and OPD department
- Choose an available appointment date or slot
- Complete mobile OTP verification
- Use or link an ABHA
- Receive an appointment confirmation
- Download or print an OPD appointment slip
- Access lab reports where enabled
- Book appointments for supported follow-up services
ORS is not limited to AIIMS hospitals. It is a broader government hospital registration platform, so patients first need to select the correct state, hospital and department during booking.
AIIMS New Patient and Follow-Up Appointment Difference
Choosing the correct patient type matters because first-time AIIMS registration and follow-up consultation are not always handled in exactly the same way.
A new patient usually needs a fresh registration or UHID for the selected hospital. A returning patient may already have a hospital ID, UHID or medical record that can be used to link the next appointment to previous treatment.
| Patient Type | How AIIMS OPD Registration Usually Works |
|---|---|
| New patient | Creates a new hospital registration/appointment for the selected department |
| Existing patient | Uses previous hospital details where supported |
| Follow-up patient | Returns to the department after an earlier consultation |
| Referred patient | May need referral papers depending on the specialty or clinic |
| Emergency patient | Goes directly to the emergency department rather than waiting for a routine OPD slot |
For first-time ORS registration, the official booking flow asks the patient to choose the hospital and department, select an appointment date, enter personal details and complete verification. ORS also states that a new patient requires a registered mobile number or ABHA for appointment booking.
Returning patients need to avoid creating unnecessary duplicate registrations where their existing hospital record can be used.
How to Book AIIMS OPD Appointment Online in 2026
The AIIMS online appointment booking process starts from the ORS patient portal. The exact options displayed after hospital selection can change according to the department and slots released by that institute.
Step 1: Open the ORS Patient Portal
Visit https://ors.gov.in/ and choose the option to book an appointment.
Use the government ORS portal rather than relying on unrelated websites that ask for patient information or payment.
Step 2: Select the State and AIIMS Hospital
Choose the state where the AIIMS hospital is located and select the required institute.
For example, a patient looking for treatment at AIIMS Bhopal must select AIIMS Bhopal rather than another government hospital appearing in the same state.
Step 3: Choose the AIIMS OPD Department
Select the department related to the consultation you need.
Departments available for online booking may include specialties such as:
- General Medicine
- General Surgery
- Orthopaedics
- Dermatology
- ENT
- Ophthalmology
- Paediatrics
- Obstetrics and Gynaecology
- Cardiology
- Neurology
- Nephrology
The actual list depends on the hospital. A department being available at an AIIMS does not necessarily mean that every appointment for that department is released online.
Step 4: Select an Available Appointment Date
ORS displays the dates or appointment options released by the selected hospital.
If the date you want does not appear, it usually means that the date has not been released, the online quota is full, or appointments for that department are being managed differently.
Step 5: Choose New Patient or Existing Patient Details
Select the appropriate patient category when the option appears.
A first-time patient will normally need to provide details such as:
- Name
- Date of birth or age
- Gender
- Mobile number
- Address
- Other registration information requested by the hospital
An existing patient may be asked for previous hospital or patient-registration information.
Step 6: Complete Mobile or ABHA Verification
Follow the verification method shown on ORS.
An ABHA number is a 14-digit health identifier used within India’s digital health ecosystem. Linking ABHA can help maintain more consistent patient identification and reduce duplicate health IDs across connected systems.
Step 7: Confirm the AIIMS Appointment
Check the hospital name, department, patient details and selected appointment date before submitting.
After successful verification and booking, an appointment confirmation is generated and an SMS may be sent to the registered mobile number.
Step 8: Save the AIIMS OPD Appointment Slip
Download or print the appointment confirmation if the option is available.
Keep the registration or appointment number accessible because it can be useful at the hospital registration counter and when retrieving booking details later.
Documents Required for AIIMS OPD Registration
Patients do not usually need a large bundle of documents merely to make an online appointment, but carrying the right records can prevent delays once they reach the hospital.
For an AIIMS OPD visit, the following documents or information can be useful:
| Document or Detail | When It Is Useful |
|---|---|
| AIIMS appointment slip | Confirms online booking details |
| Mobile number used for booking | Useful for OTP and booking verification |
| Aadhaar or another valid ID | Patient identification where requested |
| ABHA details | Digital health identification where linked |
| Existing AIIMS UHID/registration card | Important for returning patients |
| Previous prescriptions | Helps the doctor understand earlier treatment |
| Investigation reports | Important for follow-up and specialist consultations |
| Referral letter | Needed where a clinic or department requires referral |
| Current medicine list | Helps avoid confusion about ongoing treatment |
For a follow-up consultation, previous AIIMS prescriptions, discharge papers, test results and patient-registration details can be more clinically useful than repeatedly creating new registrations.
Is Aadhaar Mandatory for AIIMS Online Appointment?
Aadhaar is not the only identity route presented in the current ORS appointment process.
The ORS FAQ states that a new patient needs a registered mobile number or ABHA, and its appointment process includes mobile/ABHA verification.
This distinction is useful for patients who assume they cannot make an AIIMS appointment unless Aadhaar authentication succeeds.
ABHA itself is voluntary. Patients who create an ABHA receive a unique 14-digit health identifier that can be used across participating healthcare systems.
How to Download AIIMS OPD Appointment Slip
After successfully booking an AIIMS OPD appointment, save the generated appointment details immediately.
The usual process is:
- Open the ORS patient portal.
- Access the appointment-related service.
- Verify the patient using the requested mobile or booking information.
- Open the confirmed appointment.
- Select the option to download, print or view the appointment slip.
- Save the document on your phone or print a copy.
The appointment slip may contain information such as the hospital, department, patient details, appointment date and booking or registration number.
A printed copy is convenient, but keeping a digital copy on the phone provides a backup if the paper slip is lost.
AIIMS Appointment Booked but Slip Not Downloading
A successful appointment and a failed PDF download are two separate problems. If the booking confirmation or SMS has already been received, do not immediately create another appointment simply because the slip did not download.
First check:
- Whether the appointment appears in your ORS booking record
- Whether the confirmation SMS contains the appointment number
- Whether pop-ups or downloads are blocked in the browser
- Whether the PDF opened in another browser tab
- Whether your mobile browser has permission to save files
- Whether the portal session has expired
If the appointment itself does not appear after payment or OTP confirmation, avoid repeatedly submitting registrations because this can create confusion between multiple attempts.
AIIMS OPD Appointment Not Showing or No Slots Available
One of the most common patient searches is “AIIMS appointment slot not available.”
Online availability does not represent the entire capacity of the hospital. ORS explains that appointment quotas are determined by the respective hospitals.
This means a “no slot available” message can occur because:
- The online quota for that date is full
- The department has not released future slots
- The selected clinic is not accepting new online registrations
- The department operates only on certain days
- The booking window has not opened
- The hospital is using a separate process for that specialty
- The date is a holiday or non-OPD day
Changing randomly between departments just to obtain an appointment is not useful. The department selected during registration needs to match the medical service required.
Can You Get an AIIMS Appointment Offline?
Yes. ORS itself recognizes both online appointment booking and hospital appointment-cum-registration counters.
For offline registration, patients generally need to:
- Reach the relevant AIIMS OPD registration area.
- Go to the new-patient or appointment counter.
- Provide the requested patient details.
- Select or confirm the required department.
- Obtain the registration, token or appointment details.
- Proceed according to the department’s patient queue.
Offline availability still depends on the hospital’s daily patient capacity and department rules.
Patients travelling from another district or state benefit from checking the department schedule beforehand because some specialist clinics do not operate every day.
AIIMS Delhi OPD Registration Timings and Appointment Fee
AIIMS New Delhi has its own OPD schedule, so its timings should not be treated as a universal schedule for every AIIMS hospital.
AIIMS Delhi publishes general OPD registration from 8:30 AM to 10:30 AM, with general OPD consultation from 8:30 AM to 1:00 PM. Specialty clinic registration is listed from 1:00 PM to 2:00 PM, with consultations extending from 1:00 PM to 6:00 PM.
Some individual departments can use slightly different registration windows. For example, AIIMS Delhi’s Medicine OPD lists registration from 8:30 AM to 11:00 AM.
This is why patients searching for AIIMS OPD timings need to check the timing of the actual department rather than relying on one general timing for the entire hospital.
For AIIMS Delhi, the published outpatient registration charge is ₹10 for a new OPD registration.
The ₹10 amount should not automatically be applied to every AIIMS institute because charges and registration policies can differ by hospital.
AIIMS Delhi OPD Appointment Booking by Phone
Patients trying to obtain an appointment at AIIMS New Delhi also have an official telephone appointment-booking facility.
The current AIIMS Delhi OPD appointment numbers are:
- 011-26589142
- 011-26589143
- 011-26589144
- 011-26589145
Telephone OPD booking operates from 8:30 AM to 4:30 PM Monday to Friday on working days, and 8:30 AM to 1:00 PM on working Saturdays. AIIMS Delhi states that new-case appointments through this service can be available up to one month ahead and follow-up appointments up to three months ahead, depending on slot availability.
This option is specifically useful for AIIMS Delhi patients and should not be confused with a central telephone-booking number for every AIIMS hospital.
Types of AIIMS OPD Appointments Patients May Need
Not every visit to AIIMS is a standard first-time OPD consultation. The correct booking route depends on why the patient is returning to the hospital.
New Patient OPD Appointment
This is for a patient consulting the selected AIIMS department for the first time or creating a new registration where required.
The patient selects the hospital, department and available appointment date before entering personal details.
Follow-Up AIIMS Appointment
A follow-up appointment is used when a patient has already been assessed and needs to return for:
- Review of treatment
- Medicine adjustment
- Investigation results
- Post-procedure review
- Continued specialist management
Existing patient information is important because the follow-up needs to remain connected to the correct medical record.
Specialty or Super-Specialty Appointment
AIIMS institutes provide specialist and super-specialist services, but access rules vary considerably by department.
Some clinics accept direct registrations, while others may require an internal referral, previous consultation or department-specific appointment.
Emergency Treatment
A medical emergency is not handled like an ordinary scheduled OPD consultation.
Patients with a serious or time-sensitive medical problem need the hospital’s emergency service, where clinical priority is based on the patient’s condition rather than a routine future OPD booking.
Which AIIMS Hospitals Are Operational in 2026?
The AIIMS network has expanded significantly, but all announced institutes are not at the same stage of development.
As of the latest 2026 PMSSY status, six PMSSY AIIMS are categorized as fully functional:
- AIIMS Bhopal
- AIIMS Bhubaneswar
- AIIMS Jodhpur
- AIIMS Patna
- AIIMS Raipur
- AIIMS Rishikesh
Another group has MBBS classes along with OPD/IPD services operational, including:
- AIIMS Raebareli
- AIIMS Gorakhpur
- AIIMS Mangalagiri
- AIIMS Nagpur
- AIIMS Bathinda
- AIIMS Bibinagar
- AIIMS Kalyani
- AIIMS Deoghar
- AIIMS Bilaspur
- AIIMS Rajkot
- AIIMS Guwahati
- AIIMS Vijaypur, Jammu
PMSSY reports 22 AIIMS approved/announced under the scheme, with different operational stages across the institutes. AIIMS New Delhi predates PMSSY and is therefore not part of that “22 AIIMS under PMSSY” count.
For online OPD booking, the practical question is not simply whether an AIIMS exists, but whether the required hospital and department currently provide an appointment through ORS or their hospital booking system.
How to Download AIIMS Lab Reports Online
ORS includes a Lab Reports service for participating government hospitals.
Where the selected AIIMS has connected its laboratory results to the system, a patient can generally retrieve reports using the hospital and patient-identification details requested on the portal.
The typical process involves:
Step 1: Open the ORS Lab Report Service
Go to the ORS patient portal and select Lab Reports rather than appointment booking.
Step 2: Select the Relevant Hospital
Choose the hospital where the investigation was performed.
Reports from one AIIMS cannot be retrieved simply by selecting another AIIMS.
Step 3: Enter Patient Registration Details
Provide the hospital registration number, UHID or other requested patient information.
Use the same patient details associated with the test.
Step 4: Complete Verification
Complete OTP or the verification requested by the system.
Step 5: Open and Save the Available Report
If the result has been uploaded and made available online, open the report and save or print it for the next consultation.
A missing report does not necessarily mean the test has been lost. Some investigations take longer to process, and online report availability depends on the hospital and laboratory system.
What to Carry on the Day of Your AIIMS OPD Visit
An online appointment reduces registration work, but it does not replace the medical records needed for a useful consultation.
For the hospital visit, keep together:
- Appointment slip or appointment number
- Valid patient identification
- Existing AIIMS registration/UHID details
- Previous prescriptions
- Recent blood test reports
- X-rays, CT scans or MRI reports where relevant
- Discharge summary if previously admitted
- Referral papers where applicable
- List or strips of medicines currently being taken
For a returning patient, previous AIIMS records are particularly valuable because the doctor can compare earlier findings with the current condition.
Common AIIMS ORS Booking Problems and What They Mean
Several appointment problems occur repeatedly because patients confuse hospital availability with technical errors.
| AIIMS ORS Problem | What It Usually Means |
|---|---|
| No appointment dates visible | Slots may not have been released or the quota is full |
| Department missing | Online booking may not be enabled for that department |
| OTP not received | Mobile/network delay or incorrect number |
| Appointment booked but PDF missing | Booking may still exist; retrieve it again from appointment records |
| Existing patient record not found | Entered hospital ID/details may not match the stored record |
| Preferred doctor not visible | Booking may be department-based rather than doctor-based |
| Lab report unavailable | Report may not yet be uploaded or the hospital may use another report system |
| New registration created twice | Patient details may not have been matched with the earlier UHID |
The biggest distinction is between a technical failure and an unavailable appointment slot. Refreshing the website repeatedly cannot create a hospital slot that has already been filled.
FAQs about AIIMS OPD appointment online in 2026
Can I book an AIIMS OPD appointment online in 2026?
Yes. Many AIIMS OPD appointments can be booked through the government ORS Patient Portal at ors.gov.in, depending on the hospital, department and available appointment quota.
What is required to book an AIIMS appointment online?
A new patient generally needs an active mobile number or ABHA along with personal details and the correct hospital and department selection.
Is Aadhaar compulsory for AIIMS OPD registration?
Not for every ORS booking flow. ORS currently supports patient verification using a registered mobile number or ABHA. Aadhaar can be connected with ABHA and other digital-health services.
Is AIIMS OPD treatment completely free?
Charges vary by institute and service. For example, AIIMS Delhi publishes a ₹10 new OPD registration charge, but that fee should not be assumed for every AIIMS branch.
Why are no AIIMS appointment slots showing on ORS?
The department may have exhausted its online quota, not released future dates, or may not provide that particular service through ORS. Appointment quotas are controlled by individual hospitals.
Can I visit AIIMS without an online appointment?
Offline registration or appointment counters are available at hospitals, but daily availability and departmental rules vary. Having an online appointment can make registration more predictable.
Can an old AIIMS patient book another appointment online?
Follow-up and existing-patient appointments are available for supported hospitals and departments. Keep the previous UHID, registration details and treatment records available.
Can I download an AIIMS appointment slip again?
Where the appointment is stored in ORS, the booking can usually be retrieved and the appointment details or slip viewed again after patient verification.
Can AIIMS lab reports be downloaded online?
ORS provides an online lab-report service for participating hospitals. Availability depends on whether the hospital and laboratory have connected the report to the online system.
Are AIIMS emergency appointments booked through ORS?
Routine ORS appointment booking is intended for scheduled OPD care. Patients requiring emergency medical attention need to approach the hospital emergency department rather than wait for a regular OPD appointment.
What are AIIMS Delhi OPD timings?
AIIMS Delhi lists general OPD registration from 8:30 AM to 10:30 AM and general consultation from 8:30 AM to 1:00 PM. Individual departments and specialty clinics can have different schedules.
How far in advance can I book an AIIMS Delhi appointment?
For the AIIMS Delhi telephone appointment service, new-case appointments can be available up to one month ahead, while follow-up appointments can be available up to three months ahead, subject to available slots.
AIIMS OPD Registration in 2026: What Patients Need to Remember
The AIIMS OPD appointment process in 2026 is easier when the hospital, department and patient type are selected correctly from the beginning. ORS provides online registration for participating government hospitals and allows patients to book appointments without depending entirely on registration-counter queues.
For first-time patients, an active mobile number or ABHA, correct personal details and the right OPD department are the main requirements. Existing patients benefit from keeping their previous UHID, AIIMS registration details, prescriptions and investigation reports available so their next consultation remains connected with earlier treatment.
Most importantly, AIIMS OPD timings, fees, booking windows and online slot availability are hospital-specific. AIIMS Delhi’s ₹10 registration charge or its OPD hours should not be automatically applied to AIIMS Bhopal, Patna, Rishikesh, Bhubaneswar, Raipur or another institute.
Use ors.gov.in for the online appointment services made available by the selected hospital, save the appointment confirmation after booking, and carry previous medical records on the day of consultation.
