What are the four levels of severity considered in APR-DRGs?

The four levels of severity in APR-DRGs (All Patient Refined Diagnosis Related Groups) are classified as minor, moderate, major, and severe. This classification system is utilized in healthcare to categorize patients based on the complexity and severity of their conditions, thereby impacting the resource use, cost, and reimbursement associated with different diagnoses and treatments.

The "minor" severity level is assigned to cases that require minimal intervention, while "moderate" indicates a higher level of complexity that necessitates more resources. The "major" category reflects cases that are more complicated and require significant medical intervention, and the "severe" level denotes the highest degree of severity and complexity, implying a substantial impact on patient care and resource utilization.

This structured approach allows healthcare providers to better assess and manage healthcare costs and patient outcomes based on the severity of the conditions being treated. Other options do not accurately reflect the standardized terms used in the APR-DRG classification.
