Z12.3

Encounter for screening for malignant neoplasm of breast

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 Z12.3 is a billable code used to indicate a diagnosis of encounter for screening for malignant neoplasm of breast.

Key Diagnostic Point:

Z12.3 is used to indicate an encounter for screening for malignant neoplasm of the breast, primarily aimed at early detection of breast cancer in asymptomatic individuals. This screening is crucial as it can lead to earlier diagnosis and treatment, significantly improving patient outcomes. Factors influencing health status include access to healthcare services, socioeconomic status, and education level, which can affect a patient's likelihood of participating in preventive screenings. Social determinants such as race, ethnicity, and geographic location also play a role in screening rates. Preventive care through regular screenings is essential, particularly for women over the age of 40 or those with a family history of breast cancer. The code is applicable in various healthcare settings, including outpatient clinics, hospitals, and community health programs, emphasizing the importance of routine screenings in public health initiatives.
