    ICD-10-CM Code For Congenital Malformations Of Ovaries Fallopian Tubes And Broad Ligaments: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q50 includes congenital malformations of the ovaries, fallopian tubes, and broad ligaments, such as ovarian agenesis, ectopic ovarian tissue, and other developmental anomalies affecting these structures. These ICD-10-CM diagnosis codes are used to document congenital reproductive tract anomalies, capturing anatomic site, laterality when specified, and associated clinical complexity relevant to this group. Accurate coding within the ICD-10-CM Q50 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM Q50: Congenital Malformations Of Ovaries, Fallopian Tubes And Broad Ligaments Overview

    The ICD-10-CM Q50 group includes congenital structural anomalies of the ovaries, fallopian tubes, and broad ligaments that affect the female reproductive system. These diagnoses represent developmental abnormalities present from birth that can impact fertility, menstrual function, or pelvic anatomy. Accurate coding matters for complete clinical documentation and appropriate reimbursement by reflecting the specific anatomic site and nature of the malformation.

    When to Use

    Use a code from this group when a congenital malformation of the ovary, fallopian tube, or broad ligament is diagnosed and documented, including cases identified at birth, during imaging, or during surgical exploration. Select the most specific code available to reflect the exact anatomic site and any laterality or associated findings documented in the medical record.

    Typical Clinical Scenarios

    • A neonate is evaluated by a pediatrician and pediatric gynecology after prenatal ultrasound and postnatal physical exam reveal an absent or underdeveloped ovary on one side. The infant is otherwise stable but requires imaging (ultrasound) to confirm agenesis or hypoplasia and parental counseling about potential future fertility implications; a congenital malformation code is assigned to document the anatomic abnormality. Typical codes: Q50.1, Q50.2
    • An adolescent presents to a gynecology clinic with primary amenorrhea and pelvic MRI demonstrates ovarian dysgenesis with streak gonads and associated Müllerian structural anomalies; endocrine evaluation and long-term surveillance are initiated for hormone replacement planning and malignancy risk. A congenital ovary malformation code is used to capture the developmental disorder as the reason for specialist care. Typical codes: Q50.31, Q50.32
    • An adult woman undergoing investigation for chronic pelvic pain is found at laparoscopy to have a congenital malformation of the fallopian tube (such as absence or duplication) that complicates fertility and may contribute to ectopic pregnancy risk; the operative and fertility management notes document the anatomic anomaly as a comorbidity. Typical codes: Q50.4, Q50.5, Q50.6
