Z17.0
Estrogen receptor positive status [ER+]
Clinical Classification Guidelines
Medical Intelligence & Overview
Estrogen receptor positive (ER+) status is a term used primarily in the context of breast cancer. It indicates that the cancer cells have receptors for estrogen, a hormone that can promote cancer growth. Detecting ER+ status helps doctors decide the most effective treatment options and provides insight into the likely behavior of the cancer. The ICD-10 code Z17.0 is assigned to document the estrogen receptor positive status in medical records, facilitating accurate diagnosis coding and treatment planning.
Causes & Symptoms
Clinical Causes: Genetic mutations that lead to increased expression of estrogen receptors on breast cells. Hormonal influences that affect breast tissue development and receptor expression. Family history of hormone receptor-positive breast cancers. Environmental factors that may influence hormone levels or receptor expression.
Key Symptoms: Usually no specific symptoms directly related to ER positivity; symptoms are associated with the underlying breast cancer. Presence of a lump in the breast that may be felt or seen on imaging. Changes in breast size, shape, or appearance. Nipple discharge or inversion. Skin changes over the breast, such as redness or dimpling.
Diagnostic & Treatment
Diagnosis Path: The determination of ER status involves testing breast cancer tissue samples obtained during biopsy or surgery. The most common method is immunohistochemistry (IHC), which detects estrogen receptors on cancer cells. Pathologists analyze the tissue to determine if the cancer cells are ER-positive or ER-negative. This information guides treatment decisions and prognosis assessment.
Treatment Protocols: Selective estrogen receptor modulators (SERMs) such as tamoxifen. Aromatase inhibitors like anastrozole, letrozole, or exemestane. Ovarian suppression or ablation in premenopausal women. Surgical intervention and chemotherapy may also be part of the overall treatment plan based on the cancer stage and individual health factors.

Yes, Z17.0 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report Z17.0?
Clinical documentation must specify the nature of Estrogen receptor positive status [ER+] and any associated comorbidities for accurate reporting.
