ICD10 code of Swyer Syndrome / 46 XY Complete Gonadal Dysgenesis and ICD9 code

Swyer syndrome, also known as 46 XY complete gonadal dysgenesis, is a rare genetic disorder that affects sexual development. In this condition, individuals with XY chromosomes have gonads that do not develop into testes but instead remain as streak gonads or undifferentiated tissues. As a result, affected individuals typically have female external genitalia but lack functional ovaries or uterus.

In the International Classification of Diseases, 10th Revision (ICD-10), Swyer syndrome is assigned the code Q99.1. This code falls under the category of "Other congenital malformations of genital organs," specifically describing disorders of gonads and genitalia. The ICD-10 code Q99.1 is used to classify cases of 46 XY complete gonadal dysgenesis, including Swyer syndrome.

Regarding the ICD-9 code, it is important to note that the ICD-9 system has been replaced by ICD-10. However, in the previous classification, Swyer syndrome would have been classified under the code 752.7. This code was used for "other and unspecified anomalies of ovary, fallopian tube, and broad ligament," which encompassed various congenital abnormalities of the female reproductive system.

It is crucial to consult with a healthcare professional or medical coding specialist for accurate and up-to-date coding information, as coding practices may vary and be subject to revisions.
