Implementing the International Classification of Diseases, 11th Revision (ICD-11) in West China is feasible but requires improved medical record quality and coder training. The transition presents challenges but offers more accurate clinical diagnosis expression.
Area of Science:
- Medical Informatics
- Health Information Management
- Public Health Surveillance
Background:
- The International Classification of Diseases, 10th Revision (ICD-10) has been the standard for morbidity and mortality coding.
- Transitioning to the International Classification of Diseases, 11th Revision (ICD-11) offers potential improvements in coding accuracy and clinical representation.
- Evaluating the feasibility of ICD-11 implementation is crucial for healthcare systems worldwide.
Purpose of the Study:
- To assess the feasibility of replacing ICD-10 with ICD-11 in West China for morbidity and mortality coding.
- To summarize practical experiences and provide insights for global ICD-11 transitions.
- To identify challenges and facilitators in the ICD-11 coding process.
Main Methods:
- Collected and compared ICD-10 and ICD-11 coding data from a pilot hospital over two months.
- Conducted a questionnaire survey and focused interviews with 20 medical coders.
- Analyzed changes in primary disease codes, postcoordination usage, and coder perceptions.
Main Results:
- 92.30% of primary disease codes maintained chapter allocation; 41.10% involved postcoordination.
- Topology Scale Value, Anatomy and topography, and Histopathology were common extension dimensions.
- Coders found ICD-11 more accurate but noted challenges with manual postcoordination and medical record quality.
Conclusions:
- ICD-11 implementation in West China is feasible with groundwork in medical record quality, training, and official resources.
- The transition is smoother than previous upgrades, but coding remains complex and time-consuming.
- Addressing coding obstacles and improving documentation are key for successful ICD-11 adoption.
