Q98 - Other sex chromosome abnormalities, male phenotype, not elsewhere classified
| ICD-10: | Q98 |
| Short Description: | Oth sex chromosome abnormalities, male phenotype, NEC |
| Long Description: | Other sex chromosome abnormalities, male phenotype, not elsewhere classified |
| Status: | Not Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
Q98 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of other sex chromosome abnormalities, male phenotype, not elsewhere classified. The code is not specific and is NOT valid for the year 2023 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 for Oth sex chromosome abnormalities, male phenotype, NEC
Non-specific codes like Q98 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for oth sex chromosome abnormalities, male phenotype, nec:
- BILLABLE CODE - Use Q98.0 for Klinefelter syndrome karyotype 47, XXY
- BILLABLE CODE - Use Q98.1 for Klinefelter syndrome, male with more than two X chromosomes
- BILLABLE CODE - Use Q98.3 for Other male with 46, XX karyotype
- BILLABLE CODE - Use Q98.4 for Klinefelter syndrome, unspecified
- BILLABLE CODE - Use Q98.5 for Karyotype 47, XYY
- BILLABLE CODE - Use Q98.6 for Male with structurally abnormal sex chromosome
- BILLABLE CODE - Use Q98.7 for Male with sex chromosome mosaicism
- BILLABLE CODE - Use Q98.8 for Other specified sex chromosome abnormalities, male phenotype
- BILLABLE CODE - Use Q98.9 for Sex chromosome abnormality, male phenotype, unspecified
Patient Education
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.
