Pallister-Killian Syndrome, also known as Tetrasomy 12p, is a rare genetic disorder caused by the presence of extra genetic material on chromosome 12. The ICD-10 code for this condition is Q93.89, which falls under the category of "Other specified chromosome abnormalities." Unfortunately, there is no specific ICD-9 code for Pallister-Killian Syndrome as it is an outdated coding system.
Pallister-Killian Syndrome, also known as Tetrasomy 12p, is a rare genetic disorder characterized by the presence of four copies of the short arm of chromosome 12 in some cells of the body. This condition typically results from a random error during early embryonic development and is not inherited.
In terms of medical coding, Pallister-Killian Syndrome is classified under the International Classification of Diseases, Tenth Revision (ICD-10). The specific ICD-10 code for this syndrome is Q93.89. This code falls under the category of "Other specified chromosome abnormalities," which includes various rare genetic disorders caused by specific chromosomal abnormalities.
However, it's important to note that the ICD-9 code system is no longer in use as of October 1, 2015. It has been replaced by the more comprehensive ICD-10 coding system. Therefore, there is no specific ICD-9 code for Pallister-Killian Syndrome or Tetrasomy 12p. In the previous coding system, such genetic disorders were typically classified under broader categories, such as "Other specified congenital anomalies" or "Chromosome abnormalities."
It's crucial to consult with a healthcare professional or medical coder for accurate and up-to-date coding information. They can provide the most appropriate and specific codes based on the patient's individual diagnosis and medical history.
