Background: The Indonesian Case Base Group (INA-CBGs) financing system within the National Health Insurance (NHI) program requires cost effectiveness analysis. This stu­dy aimed to investigate cost difference between INA-CBGs tariff and hospital real cost in the treatment of type 2 diabetes mellitus within the national health insurance pro­gram.

Subjects and Method: This was a cross-sectional study conducted at Yogyakarta City Hospital, Yogyakarta, Indonesia. A total sample of 9 type 2 DM patients were selected for this study. The DM patients under study were those using anti­di­u­retic combination therapy within the NHI during 2017 to 2018 period. The data of DM patients were col­lec­ted from the medical record.

Results: Seven patients (36.84%) used antidiuretic combination of insulin aspart and in­­sulin detemir. The highest effectiveness therapy was insulin combination therapy, long acting insulin, and α glycosidase, also combination therapy of fast acting insulin group, biguanid, and sulfonylureas, the effectiveness percentage of the two combi­na­tion therapies were 100%. The average direct medical cost of patients with type 2 DM hos­pitalized in Yogyakarta City Hospital was Rp 3,539,118. Based on ACER, the most cost-effective therapy in class I was combination therapy for fast acting insulin and bi­gu­anid. In class II was combination therapy for fast acting insulin and long acting insu­lin. In class III was combination therapy for biguanid and sulfonylurea. Difference in real costs with INA-CBG’s was Rp 37,715,931. There was no significant difference bet­ween the real costs and INA-CBG’s (p= 0.285).

Conclusion: There is no significant difference between the real cost and INA-CBGs.
