Analisis Perbedaan Tarif Rumah Sakit, Tarif INA-CBG’s, dan Tarif IDRG pada Pasien Diabetes Melitus Tipe 2 Rawat Inap di RS X

Hospital tariffs refer to healthcare service costs determined based on all services provided to patients. Under the National Health Insurance (Jaminan Kesehatan Nasional/JKN) program, claim payments utilize the Indonesia Case Base Groups (INA-CBGs) system. The government has also begun piloting the Indonesian Diagnosis Related Groups (iDRG) as an improvement to the INA-CBGs system. This study aimed to analyze the differences between hospital tariffs, INA-CBGs tariffs, and iDRG tariffs for hospitalized patients with Type 2 Diabetes Mellitus at Hospital X. A quantitative method with a cross-sectional design was employed, involving a sample of 60 patients selected through total sampling. Data were obtained from patient claims and analyzed using the Friedman test to examine the simultaneous differences among the three tariffs. The results indicated that the mean hospital tariff was IDR 11,017,297.55, the mean INA-CBGs tariff was IDR 5,420,666.67, and the mean iDRG tariff was IDR 6,625,216.32. The Friedman test revealed a significant difference among the three tariffs (p < 0.001). The mean difference between the hospital tariff and INA-CBGs tariff was IDR 5,596,630.88, between the hospital tariff and iDRG tariff was IDR 4,392,081.23, and between the INA-CBGs tariff and iDRG tariff was IDR 1,204,549.65. These findings indicate that the fee-for-service hospital tariff is higher than the bundled INA-CBGs and iDRG tariffs.
