Balanced autosomal translocation in normal individual

This code signifies a chromosomal abnormality where segments of chromosomes have been exchanged, but there is no net gain or loss of genetic material, resulting in a phenotypically normal individual. It represents a carrier state for a balanced translocation, often identified during genetic testing for reproductive counseling or investigation of recurrent miscarriages.

Apply this code when documentation confirms a balanced autosomal translocation in an individual who exhibits no clinical symptoms or developmental abnormalities related to the chromosomal rearrangement. This is typically used for individuals identified through karyotyping during fertility workups, prenatal screening of a partner, or family studies following the diagnosis of an unbalanced translocation in an offspring.

• Do not use this code if the individual presents with phenotypic abnormalities or developmental delays; those cases would likely indicate an unbalanced translocation or other chromosomal disorder.
• This code is for the carrier state in a normal individual; if the translocation causes a specific syndrome or condition, code that condition instead.
• Ensure the documentation explicitly states "balanced" and "autosomal translocation" to support this specific diagnosis.
