Guidelines tips
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
If the type of diabetes is not documented, the default is E11.-. Use of insulin, oral hypoglycemics or injectable non-insulin drugs adds a Z79 code, except when insulin is given temporarily.
Diabetes codes combine the type, the body system and the complication, and as many codes as needed are assigned to describe all complications.
