Here is what the guidelines state:
Genetic susceptibility status
Genetic susceptibility indicates that a person has a gene that increases the risk of that person developing the disease.
Codes from category V84, Genetic susceptibility to disease, should not be used as principal or first- listed codes. If the patient has the condition to which he/she is susceptible, and that condition is the reason for the encounter, the code for the current condition should be sequenced first. If the patient is being seen for follow-up after completed treatment for this condition, and the condition no longer exists, a follow-up code should be sequenced first, followed by the appropriate personal history and genetic susceptibility codes. If the purpose of the encounter is genetic counseling associated with procreative management, a code from subcategory V26.3, Genetic counseling and testing, should be assigned as the first-listed code, followed by a code from category V84. Additional codes should be assigned for any applicable family or personal history.
