ABSTRACT
The main purpose of diagnosis-related groups (DRGs) is to determine the type of case that is expected to obtain a similar output or service from certain hospitals. DRGs contain important data with input in the form of diagnosis, surgery, age, other complications, length of stay, and particular costs. The rationale for DRG implementation in Indonesia (INA-DRG) is that it provides tariff and transparent standardization, more objective tariff calculation on the basis of the actual cost, hospital payments that are based on the actual work load, and the ability to increase hospital service quality and efficiency. The main diagnostic categories of INA-DRG include: Disease and nervous system disorders, eye disorders, ear, nasal, oral, and larynx disorders. The basic part of the funding is the main diagnosis. The main diagnosis is the final diagnosis selected by a doctor on the patient's last bed day with the most criteria related to using resources, or what causes the longest bed day.
