Congenital anomalies have a variety of causes, such as pregnancy or delivery complications, genetic malformations and infections experienced in utero. Some congenital anomalies have no known cause.
Chapter 17 of ICD-10-CM contains codes for congenital malformation, deformations and chromosomal abnormalities. Specifically, this chapter contains the following categories:
Q00 – Q07 Congenital malformations of the nervous system
Q10 – Q18 Congenital malformations of eye, ear, face and neck
Q20 – Q28 Congenital malformations of the circulatory system
Q30 – Q34 Congenital malformations of the respiratory system
Q35 – Q37 Cleft lip and cleft palate
Q38 – Q45 Other congenital malformations of genital organs
Q50 – Q56 Congenital malformations of genital organs
Q60 – Q64 Congenital malformations of the urinary system
Q65 – Q79 Congenital malformations and deformations of the musculoskeletal system
Q80 – Q89 Other congenital malformations
Q90 – Q99 Chromosomal abnormalities, not elsewhere classified
Although there are numerous types of congenital anomalies, some of them can be classified into one of the following categories:
- Absence – missing organs or structures
- Atresia – closure of a normal body opening or tubular structure
- Double/doubling – duplication of an organ or structure
- Fusion – merging or coherence of adjacent organs or structures
- Macro – excessively large or big
- Micro – very small or microscopic
- Stenosis – narrowing of an organ or structure
Exercise:
In order to prepare you for ICD-10-CM coding of congenital anomalies, the following exercise has been prepared as an educational tool.
A 2012 ICD-10-CM code book or an electronic file of the code book contents will be needed in order to use this coding manual. To access the 2012 ICD-10-CM code book electronic files, please go online to http://www.cms.gov/ICD10/11b14_2012_ICD10CM_and_GEMs.asp#TopOfPage .
Under the “Downloads” subheading, scroll down and download the folder titled “2012 Code Tables and Index [ZIP, 16.7MB].” Once the folder is open, you will find several files, and you will need the following files when completing these exercises:
“ICD10CM_2012_Full_Tabular.pdf” – this is the 2012 ICD-10-CM Tabular List of Diseases and Injuries.
“ICD10CM_2012_Full_DIndex.pdf” – this is the 2012 ICD-10-CM Index to Diseases and Injuries.
Exercise: Use the ICD-10-CM tabular list to write the code descriptions and identify the type of anomaly for these ICD-10-CM codes. The first row has been completed as an example. Do not code from this chart, as it is to be used for educational purposes only.
