【摘要】 中枢神经系统肿瘤是起源于中枢神经系统的不同细胞或源于转移至中枢神经系统的恶性肿瘤。中枢神经系统肿瘤会导致较高的并发症发生率、致残率和病死率。中枢神经系统肿瘤的诊断非常复杂，包括综合诊断、组织病理学分类、CNSWHO分级以及分子信息等，这些诊断信息与治疗方案及预后密切相关。以脑(脊)膜瘤、胶质瘤、垂体腺瘤及转移性肿瘤编码为例，编码员需要根据临床诊断信息严格按照肿瘤性疾病的ICD-10编码步骤进行编码，如果肿瘤有神经内分泌活性，还需要进行功能活性编码。编码员必需主动学习最新诊疗规范和临床指南，不断积累临床医学知识，增强对疾病诊断的判断能力。病案管理部门应建立提高ICD编码正确率的长效机制，提高ICD编码质量。更多还原

【Abstract】 Central nervous system tumors are malignant tumors that originate from different cells of the central nervous system or originate from metastases to the central nervous system. Central nervous system tumors lead to high complication rates, disability rates, and mortality rates. The diagnosis of central nervous system tumors is very complex, including comprehensive diagnosis, histopathological classification, CNS WHO classification, molecular information, etc. This diagnostic information is closely related to treatment options and prognosis. Taking the coding of meningioma, glioma, pituitary adenoma, and metastatic tumor as an example, coders need to code according to the clinical diagnosis information in strict accordance with the ICD-10 coding steps of tumor diseases. If the tumor has neuroendocrine activity, functional activity encoding is also required. Coders must take the initiative to learn the latest diagnosis and treatment norms and clinical guidelines, continuously accumulate clinical medical knowledge,and enhance their ability to judge diseases. The medical record management department should establish a long-term mechanism to improve the correct rate of ICD coding and improve the quality of ICD coding.更多还原
