ICD-10 CM excludes - what the heck?

I spoke about ICD10-CM 'excludes' lists in a previous post.  This post is intended to point out how absurd these lists are.

If you look at E87.2 (acidosis), and look at all the excluded diagnoses of it and its parent elements, you will see a list that looks like:

•     Diabetic acidoses (reasonable; what's not reasonable is that it doesn't actually list the codes, but requires a human to interpret them; very luddite of them)
•     Diabetes insipidus
•     Familial periodic paralysis
•     Ehlers-Danlos syndrome
•     Marfan's syndrome
•     etc

 Just to emphasize how ridiculous this 'excludes1' list is, note that it is saying that someone with DI cannot have a diagnosis of acidosis coded.  Same with someone with Marfan's syndrome or Ehlers-Danlos syndrome.  As if these diagnoses were mutually exclusive. 

I guess (in these cases) we are supposed to treat 'excludes1' like 'excludes2'. (See this post).  It would make more sense for them to just make these items 'excludes2'.
