Short answer

When inpatient treatment is needed, the relevant specialty department — such as Internal Medicine(내과), Surgery(외과), Orthopedics(정형외과), or Neurology(신경과) — is generally determined by the underlying condition that requires hospitalization. In most cases, a doctor at a primary clinic or emergency room first evaluates your condition and then issues a referral to the appropriate inpatient department at a hospital or tertiary medical center.

Which department

1Internal Medicine (내과)
Internal Medicine manages a wide range of non-surgical conditions affecting organs such as the heart, lungs, liver, kidneys, and digestive system that may require inpatient monitoring or treatment. Because many hospitalization needs arise from systemic or organ-related illnesses, Internal Medicine is often the first inpatient department involved. — First / second line: You may start at a primary clinic (의원) for initial evaluation, but if hospitalization is deemed necessary, a referral to a hospital-level Internal Medicine department is generally arranged. Subspecialties such as Cardiology(심장내과) or Pulmonology(호흡기내과) may take over depending on findings.
2Surgery (외과)
Surgery handles conditions that may require surgical intervention or post-operative inpatient recovery, including abdominal, digestive, and soft-tissue issues. Inpatient stays under Surgery are common when a condition cannot be managed with outpatient treatment alone. — First / second line: A primary physician or emergency room doctor typically identifies the surgical need and refers you to a hospital with a Surgery department. If a subspecialty such as Thoracic Surgery(흉부외과) or Vascular Surgery(혈관외과) is required, further referral within the same facility is common.
3Neurology (신경과) / Neurosurgery (신경외과)
Neurology manages inpatient care for conditions such as stroke, seizure disorders, or severe neurological deterioration that require close observation. Neurosurgery becomes relevant when a surgical approach to a brain or spinal condition is being considered. — First / second line: These departments are generally accessed via referral from an emergency room or primary physician rather than walking in directly, especially when symptoms are acute. Neurology and Neurosurgery work closely together, and the treating team typically determines which department leads the inpatient admission.
4Orthopedics (정형외과)
Orthopedics manages inpatient care related to fractures, joint conditions, or musculoskeletal injuries that cannot be treated on an outpatient basis. Hospitalization under Orthopedics often involves pre- and post-operative management of bone or joint procedures. — First / second line: Initial evaluation may occur at a primary clinic or emergency room, after which a referral to a hospital-level Orthopedics department is arranged if inpatient care is warranted. The necessity of hospitalization is determined by the severity of the injury or the nature of the planned intervention.

Go to the ER / call 119 if

If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).

Sudden loss of consciousness or inability to be roused — do not attempt to choose a department; call 119 or go to the nearest emergency room immediately.
Chest pain or pressure accompanied by difficulty breathing, sweating, or pain radiating to the arm or jaw.
Sudden one-sided weakness, facial drooping, slurred speech, or severe sudden headache unlike any experienced before.
Uncontrolled bleeding that does not stop with direct pressure, or signs of severe internal bleeding such as vomiting blood or blood in stool with dizziness.
High fever with altered mental status, stiff neck, or a rash that does not fade under pressure.

Before your visit

Write down a clear timeline of your current symptoms — when they started, how they have changed, and what makes them better or worse.
Bring a complete list of all medications you are currently taking, including dosages, so the admitting team can review them.
Gather any previous medical records, test results, imaging reports, or discharge summaries related to your current condition.
Note any chronic illnesses or prior surgeries you have had, as these are routinely required during hospital admission intake.
If you are visiting from abroad, confirm your health insurance coverage and carry your insurance card or travel insurance documents.
If you already have a referral letter (진료의뢰서) from a primary clinic, bring it — it is generally required to access inpatient care at a higher-level hospital under standard health insurance terms.

General principles

In Korea's general healthcare structure, inpatient treatment is typically provided at hospitals (병원) or tertiary medical centers (상급종합병원) rather than at primary clinics (의원). A referral letter from a primary clinic is generally required to receive full health insurance benefits when being admitted to a higher-level facility, so starting at a clinic or emergency room first is a common and practical path.

The department responsible for inpatient care is almost always determined by the nature of the underlying condition — not chosen in advance by the patient. Once a doctor evaluates you and determines that hospitalization is necessary, the appropriate department is identified and the admission process begins through that specialty team.

During an inpatient stay, multiple departments may be involved in a patient's care simultaneously, with a primary team leading and consulting teams providing additional expertise. This collaborative approach is standard in hospital-level care and does not mean the initial referral was incorrect.

Patients without a referral letter may still be admitted through the emergency room if the situation is urgent, and in such cases the emergency physician coordinates the appropriate inpatient department. Understanding this pathway can help foreign patients navigate the system more smoothly, especially outside regular clinic hours.

FAQ

Can I go directly to a hospital for inpatient care without visiting a clinic first?

In general, going to a primary clinic first and obtaining a referral letter is the standard path in Korea, and doing so typically allows you to receive full health insurance benefits during hospitalization. However, if your condition is urgent, the emergency room of a hospital is an appropriate first point of contact and does not require a prior referral. A doctor there will assess whether inpatient admission is necessary.

How do I know which specialty department I will be admitted under?

The admitting department is generally decided by the doctor who evaluates you — at a clinic, emergency room, or outpatient hospital appointment — based on your symptoms and initial findings. Patients do not typically select their inpatient department themselves. If you are unsure, explaining your symptoms clearly and providing previous medical records gives the evaluating doctor the best information to make that determination.

Is the process for inpatient admission different for children or elderly patients?

For children, Pediatrics(소아청소년과) often leads or co-manages inpatient care, even when the underlying issue involves another organ system, because pediatric patients require age-specific monitoring and dosing considerations. For elderly patients, Geriatrics(노인의학과) or Internal Medicine subspecialties are frequently involved in managing complex, multi-condition admissions. In both cases, the admitting team will coordinate with relevant specialists as needed — a doctor's evaluation remains the essential first step.

What general types of assessments are typically done during a hospital admission?

Upon admission, hospitals generally conduct an intake assessment that includes reviewing your medical history, current medications, and vital signs, along with basic laboratory work or imaging as directed by the admitting physician. The specific assessments depend entirely on your condition and are determined by the treating team, not selected in advance. Bringing previous records and a clear account of your symptoms helps the team proceed efficiently.
