With the changes in ICD 10 codes in 2017, there are many diagnosis codes have been deleted or added in this year. It is very important to remain updated with new ICD 10 codes. Also, we should remember not to code any deleted ICD 10 code for any updated code. Hence, do check updated codebook or coding software like 3M, Trucode, Encoder etc. before coding the ICD 10 codes. Let use learn today the intestinal infectious diseases codes updated this year. Hope, you will learn some new ICD 10 codes after reading this article.
