    ICD-10-CM Code For Other Noninflammatory Disorders Of Uterus Except Cervix: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N85 includes noninflammatory uterine conditions such as leiomyoma of uterus, adenomyosis, and other specified and unspecified noninflammatory disorders of the uterine body that affect structure and function. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving symptomatic or asymptomatic uterine masses, abnormal uterine bleeding, pelvic pain, or fertility-related findings capturing disease type and uterine involvement. Accurate coding within the ICD-10-CM N85 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM N85: Other noninflammatory disorders of uterus, except cervix Overview

    This group of diagnoses represents structural and functional disorders of the uterine body that are not caused by inflammation, such as uterine fibroids, adenomyosis, and other noninflammatory uterine lesions. These conditions affect the female reproductive system and can cause symptoms like abnormal uterine bleeding, pelvic pain, or fertility issues. Accurate coding matters for reimbursement because it links documented clinical findings to appropriate claims processing and ensures the clinical record supports the level of care provided.

    When to Use

    Use a code from this group when clinical documentation identifies a noninflammatory uterine condition affecting the uterine body, for example leiomyoma causing heavy menstrual bleeding or adenomyosis confirmed by imaging or histology. Select the most specific code available to reflect the documented diagnosis, location, and any complications described in the medical record.

    Typical Clinical Scenarios

    • A 32-year-old woman presents to the gynecology clinic with several months of heavy, irregular menstrual bleeding and pelvic pressure. Pelvic exam and transvaginal ultrasound reveal a localized outpouching of the uterine wall consistent with a uterine diverticulum or adenomyomatous lesion without signs of infection; biopsy rules out malignancy. A noninflammatory structural uterine disorder from this group is assigned to explain the bleeding and structural abnormality. Typical codes: N85.2, N85.3
    • A 45-year-old perimenopausal patient is evaluated for chronic intermenstrual spotting and an incidental finding on imaging of multiple small benign uterine polyps. Hysteroscopic polypectomy is performed and pathology confirms benign endometrial polyps or hyperplastic nodules without inflammation. A diagnosis from this group is used to code benign noninflammatory uterine growths causing abnormal uterine bleeding. Typical codes: N85.0, N85.01, N85.02
    • A 58-year-old postmenopausal woman presents with persistent pelvic pain and increased uterine size; imaging shows a fibroid-like mass and focal myometrial degeneration suspicious for leiomyoma with degenerative change but no infection. This is managed as a chronic noninflammatory uterine disorder and may be recorded as a comorbid structural uterine condition when planning surgical management. Typical codes: N85.4, N85.5
