The term Gangrene in the index has moist and dry mentioned in the parenthesis (Non essential modifiers) so unless there is a sub entry that specifies something to the contrary wet vs dry is not important. Follow the index sub entries


Parentheses are used in both the Alphabetic Index and Tabular List to
enclose supplementary words that may be present or absent in the
statement of a disease or procedure without affecting the code number to
which it is assigned. The terms within the parentheses are referred to as
nonessential modifiers. The nonessential modifiers in the Alphabetic
Index to Diseases apply to subterms following a main term except when a
nonessential modifier and a subentry are mutually exclusive, the subentry
takes precedence. For example, in the ICD-10-CM Alphabetic Index
under the main term Enteritis, “acute” is a nonessential modifier and
“chronic” is a subentry. In this case, the nonessential modifier “acute”
does not apply to the subentry “chronic”.
If it says the gangrene is related to diabetes go to Diabetes > Gangrene. If its not go to Lower Extremity which leads to I96. Once you get to I96 you will see the excludes 1 so if any of those apply you are at the wrong code.

If you went to "Diabetes > With", it will lead you to diabetes mellitus with diabetic peripheral angiopathy with gangrene. It doesnt matter if wet or dry since its not further specified under the Diabetes w/ complication dx

Gangrene dx code selection is not driven by the term wet/moist, dry etc which are listed with parenthesis in the index. These non esssential modifiers can be ignored unless further specified in sub entries.
