Mammary duct ectasia

Mammary duct ectasia is a non-cancerous breast condition characterized by widening and inflammation of the milk ducts beneath the nipple. This can lead to symptoms such as nipple discharge, breast pain, and a palpable mass. It is often a benign, age-related change.

This code is appropriate for documenting a diagnosis of mammary duct ectasia based on clinical findings, imaging studies (e.g., mammography, ultrasound), or biopsy results. Documentation should clearly indicate the presence of dilated and/or inflamed breast ducts.

• Differentiate from other benign breast conditions like fibrocystic changes or mastitis, which have distinct codes.
• Do not use for routine screening mammograms without a specific diagnosis of duct ectasia.
• Consider sequencing with codes for associated symptoms (e.g., nipple discharge) if they are significant and treated.
