ICD-10-CM Code Z15.8

Genetic susceptibility to other disease

Version 2020 Non-Billable Code

Not Valid for Submission

Z15.8 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of genetic susceptibility to other disease. The code is NOT valid for the year 2020 for the submission of HIPAA-covered transactions.

ICD-10:Z15.8
Short Description:Genetic susceptibility to other disease
Long Description:Genetic susceptibility to other disease

Consider the following ICD-10 codes with a higher level of specificity:

  • Z15.81 - Genetic susceptibility to multiple endocrine neoplasia [MEN]
  • Z15.89 - Genetic susceptibility to other disease

Code Classification

  • Factors influencing health status and contact with health services (Z00–Z99)
    • Genetic carrier and genetic susceptibility to disease (Z14-Z15)
      • Genetic susceptibility to disease (Z15)

  • FY 2016 - New Code, effective from 10/1/2015 through 9/30/2016
    (First year ICD-10-CM implemented into the HIPAA code set)

Information for Patients


Genetic Disorders

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs.

Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder.

You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

There are three types of genetic disorders:

  • Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.
  • Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed. Chromosomes are the structures that hold our genes. Down syndrome is a chromosomal disorder.
  • Complex disorders, where there are mutations in two or more genes. Often your lifestyle and environment also play a role. Colon cancer is an example.

Genetic tests on blood and other tissue can identify genetic disorders.
