    ICD-10-CM Code For Malignant Neoplasm Of Uterus Part Unspecified: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group C55 includes malignant neoplasms of the uterus when the documentation does not specify the exact part of the uterus involved, covering unspecified uterine cancer cases. These ICD-10-CM diagnosis codes are used to document cancer diagnoses where laterality or precise uterine subsite is not recorded, capturing the presence and general location of malignancy. Accurate coding within the ICD-10-CM C55 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    The ICD-10-CM C55 group represents malignant neoplasms located in the uterus where the specific part of the organ is not specified in documentation. These diagnoses target gynecologic oncology and the female reproductive system. Accurate coding supports correct clinical records and is important for appropriate reimbursement and claim processing.

    When to Use

    Use a code from this group when clinical documentation confirms a uterine malignancy but does not specify the exact part of the uterus involved. Select a more specific uterine neoplasm code only if the medical record identifies the precise uterine subsite.

    Typical Clinical Scenarios

    • An older postmenopausal woman presents to gynecologic oncology with abnormal uterine bleeding and pelvic pain; imaging shows an endometrial mass that cannot be definitively localized to the corpus uteri or cervix on biopsy, and histopathology confirms malignant epithelial neoplasm of uterine origin. The uncertainty about the exact uterine site leads to assignment of a code from this group when documentation does not specify a more precise uterine location. Typical codes: C55
    • A patient with a history of treated endometrial carcinoma presents to clinic for surveillance after surgery and adjuvant therapy; follow-up imaging demonstrates a recurrent pelvic mass involving the uterus but operative and pathology reports cannot determine the specific uterine subsite involved. Because the malignancy is identified as originating in the uterus without a specified part, a code from this group is used for ongoing care and recurrence coding. Typical codes: C55
    • An emergency department visit for acute pelvic pain with heavy vaginal bleeding in a patient with known gynecologic malignancy; charting and preliminary pathology indicate a uterine primary tumor but the exact anatomic sublocation within the uterus is not documented due to limited evaluation in the ED. For the acute presentation where only uterine malignancy is documented without specified part, a code from this group is assigned for the ED encounter and initial management. Typical codes: C55
