NOS codes in ICD10

ICD10 allows assigning diagnoses that are not on the list to more general "NOS" codes. Diagnoses for which we don't have a specific code should be coded as the next more general NOS code. This includes diagnoses that would be included in the standard ICD10 codes but that were not included in our subset (see here for more info).
