Balanced rearrangements and structural markers, not elsewhere classified (Q95)

The ICD-10 code Q95 series is used to identify various types of balanced chromosomal rearrangements and structural markers that are not classified elsewhere. These codes cover conditions where genetic material is rearranged but no genetic material is gained or lost, which can occur in both normal and abnormal individuals.

Codes such as Q95.0 describe a balanced translocation and insertion in a normal individual, also known as a balanced autosomal translocation. Q95.1 covers chromosome inversions in normal individuals, while Q95.2 and Q95.3 refer to balanced autosomal and sex/autosomal rearrangements in abnormal individuals. The code Q95.5 identifies individuals with autosomal fragile sites. Others like Q95.8 and Q95.9 capture other or unspecified balanced rearrangements. Understanding the ICD-10 code for balanced rearrangements helps healthcare professionals document chromosomal abnormalities precisely, supporting genetic counseling and diagnostic clarity when dealing with structural chromosomal variations such as balanced translocations, inversions, and fragility sites.
