Asymptomatic hemophilia A carrier

This code identifies an individual who carries the genetic mutation for hemophilia A but does not exhibit any signs or symptoms of the bleeding disorder themselves. These individuals are typically female and are at risk of passing the gene to their offspring.

This code is used when a patient, often identified through family history or genetic testing, is confirmed to be a carrier of hemophilia A without experiencing any bleeding episodes or other clinical manifestations of the disease. It is frequently applied in reproductive counseling or genetic screening scenarios.

• Always confirm genetic testing results or a clear family history indicating carrier status.
• Do not use this code if the patient has any symptoms of hemophilia A; a more specific hemophilia code would be appropriate.
• Consider co-reporting with codes for genetic counseling (e.g., Z31.5) if applicable.
