    ICD-10-CM Code For Benign Neoplasm Of Breast: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group D24 includes benign neoplasms of the breast such as fibroadenoma and other nonmalignant mammary tumors affecting breast tissue. These ICD-10-CM diagnosis codes are used to document encounters for evaluation, monitoring, or treatment of noncancerous breast masses, capturing lesion laterality and clinical complexity when applicable. Accurate coding within the ICD-10-CM D24 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM D24: Benign Neoplasm Of Breast Overview

    The ICD-10-CM D24 group represents benign tumors of the breast, most commonly fibroadenomas and other nonmalignant mammary neoplasms. These diagnoses target breast tissue and related structures of the female or male breast. Accurate coding supports correct claim processing and helps ensure clinical records reflect the benign nature of the lesion for appropriate care planning and reimbursement.

    When to Use

    Use a code from this group for encounters involving diagnosis, evaluation, monitoring, or treatment of benign breast tumors documented by the clinician. Select codes that reflect documented laterality and specific benign tumor type when available.

    Typical Clinical Scenarios

    • A woman in her 40s presents to her primary care clinician with a palpable, well-circumscribed, mobile lump in the upper outer quadrant of the right breast discovered during self-exam. Imaging with diagnostic mammography and targeted ultrasound demonstrates a 2-cm oval, circumscribed, hypoechoic mass with posterior enhancement consistent with a fibroadenoma; core needle biopsy confirms a benign neoplasm of the breast. A code from this group is assigned to document the benign breast tumor identified by imaging and histology. Typical codes: D24.2
    • A postmenopausal patient attends a routine breast clinic visit for evaluation of persistent breast fullness and nipple inversion on the left side; mammography detects a noncalcified, well-defined lesion in the subareolar region. Surgical excision is planned for symptomatic relief and pathology returns benign subareolar nodular tissue consistent with a benign breast neoplasm localized to the nipple/areolar complex. A diagnosis code from this group is used to record the benign lesion specific to the nipple/areola location. Typical codes: D24.1
    • A young adult presents to urgent care with localized breast pain and erythema; ultrasound shows an inflammatory change adjacent to a previously documented benign breast mass, with no abscess. The visit documents management of acute breast symptoms in the presence of an established benign breast neoplasm, so a code from this group is reported to indicate the underlying benign tumor as a comorbid condition influencing evaluation and treatment. Typical codes: D24.9
