Congenital malformations of genital organs (Q50-Q56)
ICD-10 codes Q50-Q56 are dedicated to diagnosing and classifying congenital malformations of the genital organs in both females and males. These codes help healthcare providers identify specific structural anomalies present from birth, ensuring precise documentation and appropriate care.
This range covers a wide spectrum of birth defects affecting female reproductive organs such as the ovaries, fallopian tubes, uterus, cervix, vagina, and vulva; including conditions like congenital absence (e.g., Q50.01 for unilateral absence of ovary), uterine malformations (e.g., Q51.3 for bicornate uterus), vaginal anomalies like imperforate hymen (Q52.3), and vulvar abnormalities (Q52.5 for labial fusion). Male genital abnormalities are also included, such as undescended testicles (Q53), hypospadias subtypes (Q54.0 balanic, Q54.1 penile), and malformations of the penis (Q55.6). Additionally, this category incorporates complex conditions related to ambiguous genitalia and pseudohermaphroditism (Q56), addressing disorders of sex development. Synonyms like "agenesis of ovary," "Mayer Rokitansky Küster Hauser syndrome," or "cryptorchidism" correspond to their respective ICD-10 codes, aiding coders in linking clinical diagnosis terms to the correct codes within this specialized chapter.

Instructional Notations
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
