目的规范垂体瘤的疾病分类编码。方法依据垂体瘤的临床特点和编码原则探讨垂体瘤的正确编码。结果遵循编码原则是垂体瘤正确编码的基础,搞清垂体腺瘤是否有功能活性是垂体瘤正确编码关键。结论编码员不但要熟知疾病编码原则,还要掌握与疾病编码有关的医学知识,才能使疾病分类更准确、信息利用更有价值。 Objective To standardize the pituitary tumor disease classification code. Methods Based on the clinical features and coding principles of pituitary adenomas, we discussed the correct coding of pituitary tumors. The results follow the coding principle is the basis of the correct coding of pituitary tumors, to find out whether pituitary adenoma is a functional activity of pituitary tumors is the key to the correct coding. Conclusion The coder not only needs to be familiar with the principle of disease coding, but also master the medical knowledge related to disease coding in order to make the classification of diseases more accurate and make more use of information.
