Retraction of nipple

This code describes an acquired inward pulling or depression of the nipple, which can be unilateral or bilateral. It represents a non-puerperal condition where the nipple is inverted or retracted below the surface of the areola.

Use this code for patients presenting with an acquired nipple retraction not related to pregnancy or lactation. Documentation should clearly state "nipple retraction" and specify if it is acquired, distinguishing it from congenital forms.

• Differentiate from congenital nipple inversion, which is coded elsewhere.
• Always review documentation to confirm the acquired nature of the retraction.
• Investigate for underlying causes, such as malignancy or inflammation, and code those conditions secondarily if identified.
