Acquired absence of unspecified breast and nipple

📋Clinical Description

This code indicates the complete removal or congenital absence of a breast and its associated nipple, where the specific side (left or right) is not documented. This condition can result from surgical procedures like mastectomy or from developmental anomalies.

🎯When to Use

Apply this code when documentation clearly states the absence of a breast and nipple without specifying laterality. This is often seen in cases where the operative report or pathology report does not explicitly mention "left" or "right" or when the patient's record simply states "mastectomy" without further detail on the side.

💡Coding Tips

Only use this code when laterality is truly unspecified in the medical record.
Always query the provider for clarification on laterality if it's missing, to allow for more specific coding.
Do not use this code for partial mastectomy or lumpectomy; those procedures do not result in the absence of the entire breast.
