All India Institute of Medical Sciences, New Delhi is India’s original AIIMS and one of the country’s most important public teaching and referral hospitals. The Ansari Nagar campus combines undergraduate and postgraduate medical education, research and high-volume patient care across general specialties and complex super-specialties. Patients are referred to AIIMS from Delhi and across India for difficult medical, surgical, neurological, cardiac, renal, gastrointestinal, cancer and other conditions. Its OPD system is therefore different from a typical private hospital: registration windows, referrals and clinic schedules matter as much as the name of the specialist.
General OPD registration is listed from 8:30 AM to 10:30 AM, with consultation generally from 8:30 AM to 1:00 PM. Speciality clinics have separate afternoon windows, and many super-speciality services require referral. Patients should use the appointment system and reach early. This guide focuses on AIIMS New Delhi, its OPD process, department locations, services and contacts.

Major Specialities and Clinical Services
AIIMS provides a very broad range of general and super-speciality services. The RAK OPD Block itself houses multiple departments over several floors, while dedicated centres manage additional advanced care.
| Clinical Area | Key Services |
| Medicine & Allied | General medicine, nephrology, gastroenterology, endocrinology and related services |

Facilities and Diagnostic Services
AIIMS is a referral institution with extensive laboratory, imaging, procedural, operating-theatre and critical-care infrastructure. The exact facility location depends on the department or centre managing the patient.
| Facility | Purpose / Availability |
| Diagnostics | Laboratory, radiology and speciality diagnostic services across campus |
| Operating Theatres | Major surgical and super-speciality operation facilities |
| Critical Care | ICU and high-dependency services linked to clinical departments |
| Blood Centre | Transfusion-medicine and blood-support services |
| Pharmacy / Medicines | Institutional medicine-dispensing arrangements for eligible patients |
| Emergency Services | Round-the-clock emergency care through designated emergency areas |
| Rehabilitation | PMR, physiotherapy and allied rehabilitation services |
| Teaching & Research | Specialist care integrated with a major medical teaching and research institution |
Emergency and Urgent Care
Emergency services operate separately from routine OPD. Patients with severe chest pain, stroke symptoms, major trauma, uncontrolled bleeding, loss of consciousness, severe breathing difficulty or another urgent condition should use the designated emergency area rather than waiting for an OPD appointment.
OPD Charges, Referrals and Patient Support
AIIMS is a public institution, so the patient pathway differs from private cashless insurance systems. Registration charges are nominal, while tests, procedures and medicines follow institutional rules. Some specialty clinics require referral and patients should keep all AIIMS documents together for subsequent visits.
| Patient Situation | What to Carry / Confirm |
| OPD card / registration | AIIMS Citizen Charter lists a nominal OPD card charge; verify current counter rules. |
| Referral | Carry referral letters where required for speciality or super-speciality clinics. |
| Government-scheme documents | Carry relevant beneficiary cards or authorisations if seeking treatment under a notified scheme. |
What to Carry for an OPD Visit
| Item | Why It Helps |
| Government photo ID | Useful for registration and identity verification |
| Appointment / registration details | Needed to locate the clinic and patient record |
| Referral letter | Essential where the speciality requires referral |
| Previous reports and imaging | Important for complex referral cases |
| Current medicine list | Helps clinicians review ongoing treatment |

Frequently Asked Questions
1. Can every patient directly book an AIIMS super-speciality clinic?
Not always. Many speciality and super-speciality clinics require a referral from AIIMS General OPD or another government institution. Check the clinic rule before travelling.
2. Should I arrive only at my consultation time?
No. Registration and verification take time. Reach early enough to complete the counter process within the published registration window.
3. Can a follow-up patient use the same registration route as a new patient?
Follow-up patients should use the instructions on their AIIMS documents or appointment record and keep the previous card and UHID details.
4. What if I am unsure which AIIMS building has my clinic?
Check the department and building on your appointment details. The RAK OPD Block houses many services, but some advanced centres are separate.
5. Can I rely on one OPD timing for every AIIMS department?
No. Published OPD windows do not apply identically to every department. Confirm the department-specific appointment information.
