Code Description

ICD-10 Z39.1 is a billable code used to indicate a diagnosis of encounter for care and examination of lactating mother.

Key Diagnostic Point:

Z39.1 is used to document encounters for the care and examination of lactating mothers, focusing on the health and well-being of both the mother and the infant. This code is essential for preventive care, as it encompasses routine assessments, education on breastfeeding techniques, and monitoring for any complications related to lactation. Social determinants of health, such as access to healthcare, socioeconomic status, and support systems, play a critical role in the health outcomes of lactating mothers. Preventive care during this encounter may include screenings for postpartum depression, nutritional counseling, and education on infant feeding practices. The examination may also address any physical concerns related to breastfeeding, such as nipple pain or mastitis. Proper documentation is crucial to ensure that all aspects of care are captured, reflecting the multifaceted nature of maternal health during lactation.
