Can someone help me to understand how to code diabetes with other documented diagnosis codes and/or complications? For other diagnosis codes that are not listed in the index or tabular, but are documented in the note, such as diabetes and anemia. Is this coded as "other complication" or is this coded as diabetes (E11.9 and D64.9). Are diabetic complication codes only coded for what is listed in the book, such as diabetes and kidney complications? Also, with new 2017 ICD10CM guidelines, I am understanding there is an assumed link between two conditions if both conditions are documented without the provider specifically documenting "due to" diabetes" etc.
