Highly Specialized Treatments
Karolinska is famous for treating conditions that other hospitals cannot handle. They focus on “highly specialized care.” This means they take the toughest cases from all over Europe and the world.
Advanced Cancer Therapy (CAR-T)
The hospital is a leader in Immunotherapy and CAR T-cell therapy. This is a revolutionary treatment where doctors reprogram your own immune system to fight cancer. It is often used for aggressive blood cancers like lymphoma and leukemia when standard chemotherapy stops working.
Pediatric Care
The Astrid Lindgren Children’s Hospital is part of Karolinska. It provides world-class care for children with rare diseases, heart defects, and neurological disorders.
Guide for International Patients
You do not have to be Swedish to get treated here. The International Patient Office (IPO) handles requests from all over the world. However, the process is strict because the hospital is public and funded by Swedish taxes.
Who Can Get Treated?
You can apply for care if you meet these criteria:
- Specialized Need: You have a condition that requires expertise not available in your home country.
- Referral: You have a medical report and referral from your local doctor.
- Funding: You have secured funding via private payment, insurance, or an EU S2 form.
Note: Emergency care is always available to anyone in Sweden, but planned specialized care requires approval from the IPO first.
How to Apply for a Second Opinion
If you are unsure about a diagnosis you received at home, you can pay for a “Medical Second Opinion” at Karolinska.
- Register on the Karolinska IPO website.
- Upload your medical records (in English).
- Pay the fee for the review.
- Receive a detailed report from a multidisciplinary team of experts.
Paying for Your Care: Insurance and Costs
Medical tourism to Sweden can be expensive if you do not have the right coverage. The costs include the medical procedures, travel, and accommodation in Stockholm.
Accepted Payment Methods
- Private Health Insurance: Many global insurance plans (like Cigna Global, Bupa, or Allianz) may cover treatments here if they are deemed medically necessary. Always check your policy for “Medical Evacuation” or “Out-of-Area Care” clauses.
- S2 Form (EU Citizens): If you live in the EU/EEA, your home country’s health system might pay for your treatment in Sweden if the care is not available at home.
- Embassy Guarantees: Some governments pay for their citizens to receive specialized surgery abroad.
- Upfront Payment: If you are paying cash, you must pay an estimated cost before treatment begins.
Estimated Costs for Common Procedures
- Medical Second Opinion: €500 – €1,500
- Specialized Surgery: €20,000 – €50,000+
- CAR-T Therapy: Varies significantly (often €300,000+)
