For a high-risk patient, link the appropriate screening mammography procedure code to V76.11 (Screening mammogram for high-risk patient). You should also account for any additional pertinent information when applicable with additional ICD-9 V codes, i.e., V10.3 (Personal history of malignant neoplasm; breast), V15.89 (Other specified personal history presenting hazards to health; other), or V16.3 (Family history of malignant neoplasm; breast).
Choosing ICD-9 Codes for diagnostic mammograms is not as easy because covered diagnosis codes vary from carrier to carrier. Reliable ICD-9 codes for 76090 (Mammography; unilateral), 76091 ( bilateral), G0204 (Diagnostic mammography, producing direct digital image, bilateral, all views) and G0206 (Diagnostic mammography, producing direct digital image, unilateral, all views) include but are not limited to:
