Klinefelter syndrome, unspecified

This code identifies Klinefelter syndrome, a genetic condition affecting males characterized by the presence of an extra X chromosome (XXY karyotype). Individuals typically present with hypogonadism, infertility, and often exhibit tall stature, learning difficulties, and other developmental variations.

Use this code when the medical record documents a diagnosis of Klinefelter syndrome without further specification of any associated complications or phenotypic features. This is appropriate when the provider has confirmed the diagnosis but has not detailed specific manifestations or variants.

• Only use this code when the documentation explicitly states "Klinefelter syndrome, unspecified" or simply "Klinefelter syndrome" without additional details.
• If specific manifestations or complications of Klinefelter syndrome are documented (e.g., intellectual disability, gynecomastia), consider coding those conditions in addition to or instead of this unspecified code, if a more specific code for Klinefelter syndrome is not available.
• Review the medical record for any genetic testing results (e.g., karyotype) that confirm the XXY genotype, which supports this diagnosis.
