    ICD-10-CM Code For Fistulae Involving Female Genital Tract: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N82 includes diagnoses for fistulae between the female genital tract and adjacent structures such as vesicovaginal, rectovaginal, and other specified or unspecified genital tract fistulae. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving abnormal communications that may involve infection, incontinence, or surgical complications, capturing organ involvement and clinical complexity. Accurate coding within the ICD-10-CM N82 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM N82: Fistulae Involving Female Genital Tract Overview

    This group represents diagnoses for abnormal connections, or fistulae, between the female genital tract and adjacent organs such as the bladder, rectum, or skin. These conditions affect the female reproductive and genitourinary systems and can cause significant morbidity, including infection, incontinence, and impaired quality of life. Accurate coding is important to reflect clinical complexity and support appropriate reimbursement for surgical and medical management.

    When to Use

    Use codes from this group when documenting a confirmed fistula between the female genital tract and another organ such as the bladder or rectum. Assign specific codes to reflect the anatomical site of the fistula and include any associated complications or postoperative status when documented.

    Typical Clinical Scenarios

    • A postpartum patient presents to the emergency department with new onset malodorous vaginal discharge, fecal matter noted in the vagina, and perineal pain three weeks after a complicated vaginal delivery with a 3rd-degree perineal tear. Examination and imaging confirm an abnormal epithelial-lined tract between the rectum and vagina causing passage of stool into the vagina; a diagnosis from this group is assigned to capture the rectovaginal communication resulting from obstetric trauma. Typical codes: N82.3
    • A woman with a history of pelvic radiation therapy for cervical cancer reports chronic urinary incontinence and recurrent urinary tract infections; cystoscopy and imaging identify a persistent epithelial-lined tract between the bladder and vagina. Because the fistulous connection is noninflammatory and related to prior pelvic intervention, a code from this group is used to document the vesicovaginal fistula as the source of symptoms. Typical codes: N82.0, N82.9
    • A patient with long-standing Crohn disease presents to outpatient gynecology with chronic vaginal drainage, intermittent perianal pain, and prior diagnosis of perianal fistulizing disease; evaluation reveals a fistula extending from the cervix or uterus to the vagina associated with the underlying gastrointestinal condition. This chronic comorbidity case is coded to describe the genital tract fistula complicating her systemic inflammatory bowel disease. Typical codes: N82.4, N82.8
