The four main types of structural chromosomal aberrations are deletion, duplication, inversion, and translocation.
Examples of chromosomal abnormalities include Down syndrome, Trisomy 18, Trisomy 13, Klinefelter syndrome, XYY syndrome, Turner syndrome and triple X syndrome.
ICD-10 Code for Encounter for other screening for genetic and chromosomal anomalies- Z13. 79- Codify by AAPC.
Examples of chromosomal disorders Some of the most common chromosomal abnormalities include: Down's syndrome or trisomy 21. Edward's syndrome or trisomy 18. Patau syndrome or trisomy 13.
The most common type of chromosomal abnormality is known as aneuploidy, an abnormal chromosome number due to an extra or missing chromosome. Most people with aneuploidy have trisomy (three copies of a chromosome) instead of monosomy (single copy of a chromosome).
XYY syndrome is a rare chromosomal disorder that affects males. It is caused by the presence of an extra Y chromosome. Males normally have one X and one Y chromosome. However, individuals with this syndrome have one X and two Y chromosomes. Affected individuals are usually very tall.
Encounter for antenatal screening of mother Screening is the testing for disease or disease precursors in asymptomatic individuals so that early detection and treatment can be provided for those who test positive for the disease.
What are aneuploidy screening tests? Screening tests give information about your baby's risk of a chromosome disorder. This testing is optional, and not all pregnant women have it. Some of these tests also screen for problems with your baby's brain or spine.

The Current Procedural Terminology (CPT®) code 81420 as maintained by American Medical Association, is a medical procedural code under the range - Genomic Sequencing Procedures and Other Molecular Multianalyte Assays.
Chorionic Villus Sampling ( CVS ) and amniocentesis are both diagnostic tests that can confirm whether or not a baby has a chromosome abnormality. They involve sampling of the placenta ( CVS ) or amniotic fluid (amniocentesis) and carry a risk of pregnancy loss of between 0.5 and 1 per cent.
Each person has 23 pairs of chromosomes, or 46 in all. For each pair, you get one chromosome from your mother and one chromosome from your father. About 1 in 150 babies is born with a chromosomal condition. Down syndrome is an example of a chromosomal condition.
