Analysis of National Health Insurance Reimbursement Patterns for Inpatient Services at Surakarta General Government Hospital

The National Health Insurance (JKN) program, administered by BPJS Kesehatan, has significantly expanded public access to healthcare services, particularly inpatient care. This study aims to analyze inpatient JKN reimbursement patterns at Surakarta General Government Hospital during the period of 2020 to 2024. The analysis focuses on five main variables: INA-CBGs grouping codes, class of care, severity level, INA-CBGs tariff, and actual hospital costs. A descriptive-analytic method with a quantitative approach was employed, utilizing secondary data extracted from the INA-CBGs system. The results indicate that inpatient reimbursements were predominantly concentrated in Class 3 services (64%–70%) and severity level 1 (45%–59%). From 2020 to 2022, respiratory-related cases dominated, likely due to the COVID-19 pandemic, while in 2023–2024 a shift occurred toward non-communicable diseases such as cardiovascular and metabolic conditions. A consistent negative tariff gap was identified, particularly in Class 3 and severity level 1, where INA-CBGs reimbursements were insufficient to cover actual service costs. These findings underscore the importance of periodic review of INA-CBGs tariff structures, reinforcement of Quality and Cost Control (KMKB), and optimization of reimbursement management information systems to enhance service efficiency and ensure the financial sustainability of JKN, especially in Type C hospitals that serve as the primary level of healthcare delivery.
