About ICD-9-CM V26.33

The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as Z31.5 (Encounter for procreative genetic counseling) and Z71.83 (Encounter for nonprocreative genetic counseling). All of these are approximate matches, so review the record to pick the right one.
