ICD-10-CM Code Z14.8

Genetic carrier of other disease

Version 2020 Billable Code Unacceptable Principal Diagnosis POA Exempt

Valid for Submission

Z14.8 is a billable code used to specify a medical diagnosis of genetic carrier of other disease. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code Z14.8 might also be used to specify conditions or terms like asymptomatic carrier of hereditary factor viii deficiency disease, carrier of alpha thalassemia, carrier of beta thalassemia, carrier of canavan disease, carrier of charcot-marie-tooth disease, carrier of chromosome disorder, etc The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

The code Z14.8 describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:

  • Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual’s health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.


The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Asymptomatic carrier of hereditary factor VIII deficiency disease
  • Carrier of alpha thalassemia
  • Carrier of beta thalassemia
  • Carrier of Canavan disease
  • Carrier of Charcot-Marie-Tooth disease
  • Carrier of chromosome disorder

Present on Admission (POA)

Z14.8 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here .

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.
