Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the Q52 range.

Arachnodactyly

An abnormal bone development that is characterized by extra long and slender hands and fingers, such that the clenched thumb extends beyond the ulnar side of the hand. Arachnodactyly can include feet and toes. Arachnodactyly has been associated with several gene mutations and syndromes.

Bicornuate Uterus

A congenital uterine anomaly in which the UTERUS is divided into two uterine horns with a significant cleft at the uterine fundus due to partial fusion of the MULLERIAN DUCTS. Bicornuate uterus is sometimes associated with a longitudinal vaginal septum and abnormal development of renal tracts.

Rectovaginal Fistula

An abnormal anatomical passage between the RECTUM and the VAGINA.

WAGR Syndrome

A contiguous gene syndrome associated with hemizygous deletions of chromosome region 11p13. The condition is marked by the combination of WILMS TUMOR; ANIRIDIA; GENITOURINARY ABNORMALITIES; and INTELLECTUAL DISABILITY.

About the Q52 Code Range

The ICD-10 code section Q52 covers various other congenital malformations of female genitalia, including rare structural differences present from birth. These codes are specifically used to identify and classify anomalies such as absence or duplication of the vagina, septal abnormalities, and malformations of the vulva and clitoris.

For example, Q52.0 refers to the congenital absence of vagina, also known as Mayer-Rokitansky-Küster-Hauser syndrome, a condition where the vagina and sometimes uterus are missing. Code Q52.1 relates to vaginal doubling, which includes septate vagina variants such as transverse (Q52.11) or longitudinal vaginal septum (Q52.12). Additionally, Q52.2 is used for congenital rectovaginal fistula, an abnormal fistulous connection between the rectum and vagina. Other malformations in this series address conditions like imperforate hymen (Q52.3), labial fusion (Q52.5), and various vulvar abnormalities (Q52.7 codes). The section aids in precise medical coding for congenital female genital tract anomalies to support accurate diagnosis and care documentation.
