Not Valid for Submission
Q04 is a "header" nonspecific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other congenital malformations of brain. 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.
Specific Coding for Other congenital malformations of brain
Header codes like Q04 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 other congenital malformations of brain:
- Q04.0 - Congenital malformations of corpus callosum
- Q04.1 - Arhinencephaly
- Q04.2 - Holoprosencephaly
- Q04.3 - Other reduction deformities of brain
- Q04.4 - Septo-optic dysplasia of brain
- Q04.5 - Megalencephaly
- Q04.6 - Congenital cerebral cysts
- Q04.8 - Other specified congenital malformations of brain
- Q04.9 - Congenital malformation of brain, unspecified
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code Q04:
Type 1 ExcludesType 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.
Information for Patients
Also called: Cephalic disorders
Most brain malformations begin long before a baby is born. Something damages the developing nervous system or causes it to develop abnormally. Sometimes it's a genetic problem. In other cases, exposure to certain medicines, infections, or radiation during pregnancy interferes with brain development. Parts of the brain may be missing, abnormally small or large, or not fully developed.
Treatment depends upon the problem. In many cases, treatment only helps with symptoms. It may include antiseizure medicines, shunts to drain fluid from the brain, and physical therapy.
There are head malformations that do not involve the brain. Craniofacial disorders are the result of abnormal growth of soft tissue and bones in the face and head. It's common for new babies to have slightly uneven heads, but parents should watch the shape of their baby's head for possible problems.
