Abstract

Objective. To discuss the problems in coding of percutaneous coronary intervention. Methods. Collecting 216 medical records of percutaneous coronary intervention, analyzing the mistakes of major surgery completed, and coding by ICD-9-CM-3 coding principles. Results. Of the records analyzed, 69 records had errors, the total error rate was found to be 31.9%. The main mistake committed by the coders was the omission of the code for the coronary artery, accounting for 53.2%. Conclusion. We should strengthen special training on knowledge of the ICD-9-CM3 principles of coding for coronary artery stenting surgery for cardiologists, and improve the level of business and coding ability of coders. The joint efforts of both parties will reduce the error rate in the coding of percutaneous coronary intervention.
