-Contains '''19 primary medical conditions''' of comorbidity some of which contain subcategories of diseases related to the primary category.  For a list of all diagnosis applicable that we use go to: [[:Category: Charlson Comorbid Diagnosis | Charlson Comorbid Diagnosis]] (or [[Charlson Comorbid coding (pre ICD10)#Comorbid_List]] as former may not include all sub-diagnoses).
+*The CCI takes account of 17 chronic medical conditions
+*Each of the 17 items has a certain number of points, and the total score is the sum of all of them.
+**There is one tricky thing about the scoring though:
+***Of the 17 there are two are mutually exclusive pairs: (a) Diabetes Mellitis with and without chronic complications, and (b) Liver disease as mild vs. moderate/severe. If you should qualify for both members of a pair, then only count the points for the more severe (higher scoring).  Example:  if you have diagnoses that qualify you for both mild liver disease and moderate/severe liver disease, only include the points from the latter.
