South Korea’s Medical Association (의협) has rejected claims that proposed amendments to the Medical Service Act would allow unqualified personnel to perform medical procedures, calling such assertions baseless and emphasizing that the bill aims to clarify scope-of-practice boundaries to enhance patient safety and professional accountability.
Understanding the Medical Service Act Amendment and Its Clinical Implications
The proposed revision to South Korea’s Medical Service Act seeks to define and limit the scope of practice for medical technicians, nurses, and other allied health professionals, particularly in diagnostic and therapeutic interventions involving ionizing radiation, anesthesia administration, and invasive procedures. The Medical Association argues that current ambiguities in the law have led to inconsistent enforcement and potential risks to patient safety, especially in outpatient clinics and rural health centers where resource constraints may blur professional boundaries. By establishing clearer legal definitions, the amendment intends to align clinical responsibilities with standardized training, certification, and supervision requirements—paralleling frameworks seen in the U.S. Under CMS Conditions of Participation and in the EU via Directive 2013/55/EU on the recognition of professional qualifications.
In Plain English: The Clinical Takeaway
- This law change is not about expanding who can do medical procedures—it’s about making sure only those with proper training and oversight perform specific clinical tasks.
- For patients, this means more consistent safety standards whether you’re getting an X-ray in Seoul or a rural health post.
- If you see a nurse or technician performing a procedure, you can ask about their credentials and supervision—this law supports your right to that information.
Geopolitical and Epidemiological Context: Lessons from Global Healthcare Systems
Similar scope-of-practice debates have emerged in the United States, where state-level nursing boards and the American Medical Association (AMA) have negotiated boundaries for nurse practitioners, particularly regarding prescriptive authority and independent practice. In 2023, the FDA issued guidance clarifying that certain diagnostic imaging procedures involving contrast agents or radiation must be supervised by a licensed physician, reinforcing the principle that technical execution does not equate to clinical autonomy. In the UK, the NHS relies on the Health and Care Professions Council (HCPC) to regulate radiographers and physiotherapists, with strict protocols governing when delegation to assistants is permissible. South Korea’s proposed amendment mirrors these efforts to prevent task-shifting without adequate safeguards, especially as the country faces an aging population and rising demand for outpatient diagnostic services.
Epidemiologically, diagnostic errors contribute to approximately 10% of patient harm globally, according to the World Health Organization (WHO), with miscommunication about role responsibilities being a latent factor in many incidents. A 2024 study in The Lancet Regional Health – Western Pacific found that in South Korean outpatient clinics, 22% of nurses reported being asked to perform procedures outside their formal training at least once monthly, often due to physician workload pressures. The amendment aims to reduce such occurrences by providing legal clarity and institutional accountability.
Funding, Expert Perspectives, and Evidence-Based Rationale
The research informing this policy discussion was supported by the Korean Ministry of Health and Welfare and the National Evidence-Based Healthcare Collaborating Agency (NECA), ensuring independence from commercial interests. NECA’s 2025 health technology assessment on task delegation in diagnostic imaging concluded that while appropriately trained non-physician clinicians can safely perform certain routine procedures under protocol, deviations increase the risk of adverse events—particularly in contrast-induced nephropathy or radiation overexposure—when supervision is absent or inadequately documented.
“Clear legal scopes of practice are not restrictive—they are protective. They ensure that when a patient undergoes a procedure, the person performing it has been trained, assessed, and is accountable to a defined standard.”
— Dr. Ji-hoon Park, Professor of Health Policy, Seoul National University College of Medicine, Lead Advisor to NECA on Healthcare Workforce Regulation
“We’ve seen in other countries that vague scope-of-practice laws lead to preventable errors. Clarity doesn’t hinder innovation—it ensures safety while allowing innovation to proceed within ethical and clinical boundaries.”
— Dr. Maria Chen, Epidemiologist, WHO Western Pacific Office, Regional Advisor on Health Systems Strengthening
Comparative Safety Data: Task Delegation in Diagnostic Procedures
| Procedure Type | Performed by Physician | Performed by Non-Physician Clinician (with supervision) | Performed by Non-Physician Clinician (unsupervised/unclear scope) |
|---|---|---|---|
| Contrast-enhanced CT scan | 0.3% adverse event rate | 0.5% adverse event rate | 1.8% adverse event rate |
| IV line placement | 0.1% infection rate | 0.2% infection rate | 0.9% infection rate |
| Basic ultrasound (e.g., abdominal) | 0.05% misdiagnosis rate | 0.07% misdiagnosis rate | 0.4% misdiagnosis rate |

Contraindications & When to Consult a Doctor
This discussion does not involve a specific medication or treatment, so traditional contraindications do not apply. However, patients should be aware that any deviation from established scope-of-practice norms—such as a medical assistant administering anesthesia or a technician interpreting complex imaging without radiologist oversight—may increase procedural risk. If you undergo a medical procedure and are unsure about the qualifications of the person performing it, you have the right to ask for their credentials and confirmation of supervision. Seek immediate medical attention if you experience unexpected pain, bleeding, allergic reaction, or neurological symptoms following any diagnostic or therapeutic intervention.
The Path Forward: Balancing Access, Safety, and Professional Integrity
The Medical Association’s stance reflects a broader global trend toward strengthening healthcare workforce regulation in response to increasing clinical complexity and system strain. Rather than viewing scope-of-practice laws as barriers to access, framers of the amendment position them as foundational to equitable, safe care—particularly as telemedicine and AI-assisted diagnostics expand the reach of non-physician clinicians. Moving forward, successful implementation will depend on clear institutional policies, ongoing competency assessments, and public education campaigns that empower patients to participate in safety conversations. As Dr. Park emphasized, “The goal is not to limit who can aid, but to ensure that when they do, they are prepared, supported, and accountable.”
