HIRA data
DISEASE
HIRA receives medical claims data from all hospitals in South Korea, evaluates the appropriateness of the claims, and approves reimbursements from the National Health Insurance. All healthcare services rendered under national health insurance are claimed for reimbursement on a weekly or monthly basis, and are reported to HIRA and stored in HIRA’s in-house data warehouse. We collected information regarding age, sex, medications, comorbid conditions [classified using the International Classification of Disease, Tenth Revision (ICD-10) codes], and exacerbations.
