When you visit a hospital for medical care, your journey is typically categorized into one of two main departments based on the nature of your visit. This categorization determines the type of care you receive and the way your visit is registered in the hospital’s system. You will often hear the terms ‘OPD’ and ‘IPD’ and be assigned a specific number for your visit. For any patient or their family members, it is helpful to understand the difference between an IPD number vs an OPD number in hospitals. These numbers are temporary identifiers for a specific episode of care and are different from your permanent hospital ID.
What is an OPD Number?
OPD stands for Out-Patient Department. An OPD number is a unique identification number that is assigned to you when you visit a hospital for a consultation with a doctor, a diagnostic test, or a minor procedure that does not require you to be admitted to the hospital. You are considered an ‘out-patient’ because you walk in for treatment and walk out on the same day. The OPD is the first point of contact for most patients with the hospital. Your visit to the OPD generates a record that includes the doctor’s consultation notes, the tests prescribed, and the diagnosis. Each time you visit the OPD for a new consultation, a new OPD number or visit ID may be generated, which is then linked to your permanent hospital ID.
What is an IPD Number?
IPD stands for In-Patient Department. An IPD number is a unique identification number that is assigned to you when you are formally admitted to the hospital for treatment, a surgery, or observation for a period of 24 hours or more. You are considered an ‘in-patient’ because you occupy a hospital bed. The IPD number is the primary reference for your entire hospital stay. All the services you receive during your admission—including doctor’s visits, nursing care, medications, surgeries, and meals—are recorded and billed against this IPD number. This number is also known as an admission number or an in-patient registration number.
IPD Number vs an OPD Number: A Detailed Comparison
The key difference between an OPD and an IPD number lies in the nature of the patient’s stay at the hospital. Here is a clear comparison:
| Parameter | OPD (Out-Patient Department) Number | IPD (In-Patient Department) Number |
|---|---|---|
| Meaning | A number for patients who receive care without being admitted to the hospital. | A number for patients who are formally admitted to the hospital for an overnight stay or longer. |
| Duration of Stay | Short, typically a few hours on the same day. | Long, involving at least one overnight stay (more than 24 hours). |
| Type of Care | Consultations, routine check-ups, diagnostic tests, minor procedures. | Surgeries, intensive care, continuous monitoring, and management of serious illnesses. |
| Requirement of a Bed | No hospital bed is required. | A hospital bed is assigned. |
| Example Scenario | Visiting a dermatologist for a skin rash and getting a prescription. | Being admitted for an appendicitis surgery and staying in the hospital for three days. |
| Health Insurance | Most basic health insurance policies do not cover OPD expenses. | IPD expenses are the primary coverage offered by all standard health insurance policies. |
The Link with the UHID Number
While OPD and IPD numbers are generated for specific visits or admissions, they are all linked together under one master identifier. This permanent number is the Unique Health Identification Number (UHID). The UHID is your permanent patient ID with that hospital. So, over the years, your single UHID will have a record of all your OPD visit numbers and IPD admission numbers, creating a comprehensive medical history within that hospital’s system.
This entire hospital record can also be linked to your national health ID, the ABHA Number, with your consent, making your health history portable across different healthcare providers.
Importance in Health Insurance
The distinction between IPD and OPD is extremely important when it comes to health insurance claims. Most health insurance policies in India are ‘indemnity policies’ that primarily cover expenses related to hospitalization (in-patient care). When you are admitted to a hospital and generate an IPD number, you can claim your expenses using your cashless TPA ID card or through reimbursement. OPD expenses, on the other hand, are generally not covered, unless you have a specific policy with an OPD benefit rider. Knowing whether your treatment will be classified as IPD or OPD is key to understanding your insurance coverage.
Frequently Asked Questions (FAQs)
1. What is a ‘Day Care Procedure’ and is it considered IPD or OPD?
A Day Care Procedure is a medical treatment or surgery (like chemotherapy or cataract surgery) that requires hospitalization for a few hours but not an overnight stay. Due to technological advancements, many such procedures are now completed within a day. For health insurance purposes, most Day Care Procedures are considered equivalent to in-patient hospitalization (IPD) and are covered by your policy, even if the stay is less than 24 hours.
2. Will I get a new IPD number every time I am admitted to the hospital?
Yes, typically, a new and unique IPD or admission number is generated for each separate instance of hospitalization. This helps the hospital to manage the billing and medical records for that specific admission episode accurately. All these IPD numbers will, however, be linked to your permanent UHID.
3. The doctor saw me in the Emergency Room. Is that OPD or IPD?
An initial visit to the Emergency Room (ER) is usually treated as an out-patient visit. If the doctor decides after the initial assessment that you need to be admitted for further treatment or observation, you will then be formally admitted, and an IPD number will be generated for you.
4. Why do I need to keep my IPD number safe?
The IPD number is the main reference for your entire hospitalization. You will need this number to track your bills, for any queries with the hospital’s billing department, and, most importantly, for your health insurance claim process. It is a key identifier on all your hospital records and the final discharge summary.
5. Can I get my medical records using my OPD number?
Yes, you can use your OPD number to get the records for that specific consultation. However, it is always better to use your permanent UHID number, as that will allow the hospital staff to access your entire history, including all past OPD and IPD visits.
