Is Billable?

Code Classification

  • Factors influencing health status and contact with health services
    (Z00–Z99)
    • Persons encountering health services for examinations
      (Z00-Z13)
      • Encounter for screening for other diseases and disorders
        (Z13)

Z13.7 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of encounter for screening for genetic and chromosomal anomalies. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Encntr screen for genetic and chromosomal anomalies

Non-specific codes like Z13.7 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for encntr screen for genetic and chromosomal anomalies:

  • Use Z13.71 for Encounter for nonprocreative screening for genetic disease carrier status - BILLABLE CODE

  • Use Z13.79 for Encounter for other screening for genetic and chromosomal anomalies - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Genetic Testing

What is genetic testing?

Genetic testing is a type of medical test that looks for changes in your DNA. DNA is short for deoxyribonucleic acid. It contains the genetic instructions in all living things. Genetic tests analyze your cells or tissue to look for any changes in:

  • Genes, which are parts of DNA that carry the information needed to make a protein
  • Chromosomes, which are thread-like structures in your cells. They contain DNA and proteins.
  • Proteins, which do most of the work in your cells. Testing can look for changes in the amount and activity level of proteins. If it finds changes, it might be due to changes in your DNA.

Why is genetic testing done?

Genetic testing may be done for many different reasons, including to:

  • Find genetic diseases in unborn babies. This is one type of prenatal testing.
  • Screen newborn babies for certain treatable conditions
  • Lower the risk of genetic diseases in embryos that were created using assisted reproductive technology
  • Find out if you carry a gene for a certain disease that could be passed on to your children. This is called carrier testing.
  • See whether you are at increased risk of developing a specific disease. This may be done for a disease that runs in your family.
  • Diagnose certain diseases
  • Identify genetic changes that may be causing or contributing to a disease that you were already diagnosed with
  • Figure out how severe a disease is
  • Help guide your doctor in deciding the best medicine and dosage for you. This is called pharmacogenomic testing.

How is genetic testing done?

Genetic tests are often done on a blood or cheek swab sample. But they may also be done on samples of hair, saliva, skin, amniotic fluid (the fluid that surrounds a fetus during pregnancy), or other tissue. The sample is sent to a laboratory. There, a lab technician will use one of several different techniques to look for genetic changes.

What are the benefits of genetic testing?

The benefits of genetic testing include:

  • Helping doctors make recommendations for treatment or monitoring
  • Giving you more information for making decisions about your health and your family's health:
    • If you find out that you are at risk for a certain disease, you might take steps to lower that risk. For example, you may find out that you should be screened for a disease earlier and more often. Or you might decide to make healthy lifestyle changes.
    • If you find out that you are not at risk for a certain disease, then you can skip unnecessary checkups or screenings
    • A test could give you information that helps you make decisions about having children
  • Identifying genetic disorders early in life so treatment can be started as soon as possible

What are the drawbacks of genetic testing?

The physical risks of the different types of genetic testing are small. But there can be emotional, social, or financial drawbacks:

  • Depending on the results, you may feel angry, depressed, anxious, or guilty. This can be especially true if you are diagnosed with a disease that does not have effective treatments.
  • You may be worried about genetic discrimination in employment or insurance
  • Genetic testing may give you limited information about a genetic disease. For example, it cannot tell you whether you will have symptoms, how severe a disease might be, or whether a disease will get worse over time.
  • Some genetic tests are expensive, and health insurance might only cover part of the cost. Or they may not cover it at all.

How do I decide whether to be tested?

The decision about whether to have genetic testing is complex. In addition to discussing the test with your health care provider, you can meet with a genetic counselor. Genetic counselors have specialized degrees and experience in genetics and counseling. They can help you understand the tests and weigh the risks and benefits. If you do get a test, they can explain the results and make sure that you have the support that you need.

Health Screening

Screenings are tests that look for diseases before you have symptoms. Screening tests can find diseases early, when they're easier to treat. You can get some screenings in your doctor's office. Others need special equipment, so you may need to go to a different office or clinic.

Some conditions that doctors commonly screen for include:

  • Breast cancer and cervical cancer in women
  • Colorectal cancer
  • Diabetes
  • High blood pressure
  • High cholesterol
  • Osteoporosis
  • Overweight and obesity
  • Prostate cancer in men

Which tests you need depends on your age, your sex, your family history, and whether you have risk factors for certain diseases. After a screening test, ask when you will get the results and whom to talk to about them.
