The ICD-10-CM diagnosis code Z85.3, titled “Personal history of malignant neoplasm of breast,” is a vital tool in medical coding and documentation. It plays a crucial role in tracking patient history, informing healthcare decisions, and ensuring accurate billing and reimbursement. This guide provides a comprehensive overview of the Z85.3 code, its applications, and key considerations for healthcare professionals and anyone seeking to understand diagnosis codes for personal history of breast cancer.
Decoding ICD-10-CM Z85.3: Personal History of Breast Cancer
Z85.3 is a specific, billable code within the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) system. It is used to indicate that a patient has a personal history of malignant neoplasm of the breast. This means the patient has been previously diagnosed with and treated for breast cancer, but the cancer is no longer considered active at the time of the encounter for which this code is being used.
Key features of the Z85.3 code:
- Billable/Specific Code: Z85.3 is a billable code, meaning it is recognized by insurance companies for reimbursement purposes. It is also a specific code, providing a precise classification within the ICD-10-CM system.
- Effective Date: The Z85.3 code is part of the 2025 ICD-10-CM edition, effective from October 1, 2024. This code has been consistently used in previous editions dating back to 2016, highlighting its established role in medical coding.
- American Standard: Z85.3 is the American ICD-10-CM version. It’s important to note that international versions of ICD-10 may have variations.
- POA Exempt: Z85.3 is exempt from Present On Admission (POA) reporting. POA reporting is used for inpatient claims to differentiate between conditions present at the time of admission and those that develop during the hospital stay. Exemption for Z85.3 implies that whether the breast cancer history was present on admission or not does not need to be specifically reported for this code.
Synonyms for Diagnosis Code Z85.3
To ensure clarity and accuracy in medical documentation, several synonyms are recognized as equivalent to “Personal history of malignant neoplasm of breast” and can be effectively represented by the Z85.3 code. These approximate synonyms include:
- History of cancer of the breast

These synonyms encompass various types and presentations of past breast cancer diagnoses, all falling under the umbrella of personal history and appropriately coded with Z85.3.
Understanding Annotation Back-References in ICD-10-CM
The ICD-10-CM system utilizes annotations to provide further guidance and context for specific codes. Annotation back-references, in the context of Z85.3, point to other codes within the ICD-10-CM system that contain annotations relevant to Z85.3. These annotations can include:
