At the extreme, without the necessary funds no health workers would be employed, no medicines would be available and no health promotion or prevention would take place. 1 Hospital medical billing is the process of submitting and following up on claims to insurance companies in order to receive payment for services rendered by hospitals. The hospital billing process begins when a patient arrives to the hospital for diagnosis and treatment of an injury, illness, disease, or condition. Until the patient‟s departure, all of the services and items provided are recorded to patient‟s account. In the next step, all infor mation and charges are processed for billing based on the requirements of insurance companies, which generally have reimbursement rules. During the billing process, if a hospital does not meet the requirements of an insurance company, stoppages to hospital payments and fines to the hospitals are generally charged. 2 Accurate billing is crucial for the financial health of medical institutions. Billing and coding are based on what services are documented by the provider and selection of the appropriate code is most commonly done by the provider or a coding specialist. 3 Medical coding is the transformation of healthcare diagnosis, procedures, medical services, and equipment into universal medical alphanumeric codes. It can be subsequently used for ABSTRACT Background: The accuracy of clinical coding is very important in the proper financing of health care centers. During January to February 2019, only 35 out of 60 obstetrical cases that were well coded (58%) in Naili DBS Hospital and this miscoding would led to a big financial loss. The aim of this study is to determine the effect of training on coding accuracy. Methods: This study was conducted during April 2019 in Naili DBS Hospital using quasi experimental method, with one group pretest and post-test design. All 11 participants were given a pretest consisted of 10 long cases (maximum score=38) and the training was conducted based on the identified needs from the preliminary audit. They were then given a post-test to see the effect of the training. Results: The mean score of pretest was 10.7 and the mean score of post-test was 19.7. The individual scores were normalized and then analyzed using SPSS with paired sample T-test. Based on statistical analysis, p<0.005 meaning the traning is statistically significant on improving the coding accuracy in obstetrical diagnosis. Conclusions: The training has significantly improved the score of well coded obstetrical diagnosis, even though the participants have not reached the maximum score. Furthermore, our study suggests that it is important to analyze the coders‟ performance months after the training by conducting a coding audit.
