2021 ICD-10-CM Code Q93
Monosomies and deletions from the autosomes, not elsewhere classified
Not Valid for Submission
Q93 is a "header" nonspecific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of monosomies and deletions from the autosomes, not elsewhere classified. The code is NOT valid for the year 2021 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.
| ICD-10: | Q93 |
| Short Description: | Monosomies and deletions from the autosomes, NEC |
| Long Description: | Monosomies and deletions from the autosomes, not elsewhere classified |
Code Classification
Specific Coding for Monosomies and deletions from the autosomes, NEC
Header codes like Q93 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 monosomies and deletions from the autosomes, nec:
- Q93.0 - Whole chromosome monosomy, nonmosaicism (meiotic nondisjunction)
- Q93.1 - Whole chromosome monosomy, mosaicism (mitotic nondisjunction)
- Q93.2 - Chromosome replaced with ring, dicentric or isochromosome
- Q93.3 - Deletion of short arm of chromosome 4
- Q93.4 - Deletion of short arm of chromosome 5
- Q93.5 - Other deletions of part of a chromosome
- Q93.51 - Angelman syndrome
- Q93.59 - Other deletions of part of a chromosome
- Q93.7 - Deletions with other complex rearrangements
- Q93.8 - Other deletions from the autosomes
- Q93.81 - Velo-cardio-facial syndrome
- Q93.82 - Williams syndrome
- Q93.88 - Other microdeletions
- Q93.89 - Other deletions from the autosomes
- Q93.9 - Deletion from autosomes, unspecified
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.
