About the Q50 Code Range
The Q50 section covers congenital malformations of the ovaries, fallopian tubes, and broad ligaments, detailing various structural anomalies present from birth in these female reproductive organs. These ICD-10 codes are used to identify and classify specific congenital conditions affecting these organs.
These codes include unilateral and bilateral congenital absence of an ovary (Q50.01 and Q50.02), also known as agenesis of the ovary or PAGOD syndrome, which describe missing ovaries from birth. Developmental ovarian cysts (Q50.1) and congenital torsion of the ovary (Q50.2) represent cystic formations or twisting of the ovary present at birth. Other malformations include accessory ovaries (Q50.31) and ovarian streaks (Q50.32), also called streak gonads, indicating underdeveloped ovarian tissue. Additional codes cover embryonic cysts of the fallopian tube (Q50.4) and broad ligament (Q50.5), as well as other anomalies of fallopian tubes and broad ligaments (Q50.6), such as congenital absence or abnormal shapes. Using the ICD-10 code for these specific conditions ensures precise documentation for congenital abnormalities affecting female reproductive anatomy.
