Solitary cyst of unspecified breast

This code signifies the presence of a single, fluid-filled sac within the breast tissue, the specific location of which is not documented. These cysts are typically benign and can be palpable or identified incidentally on imaging.

Apply this code when documentation confirms a solitary breast cyst without further specification of its quadrant or location within the breast. This is appropriate when imaging reports or physician notes describe a single cyst but lack detailed anatomical localization.

• Do not use this code if the cyst's specific location (e.g., upper outer quadrant) is documented; instead, use a more specific N60.0- subcategory.
• Ensure the documentation explicitly states "solitary cyst" to differentiate from multiple cysts (N60.1-).
• This code is for benign cysts; do not use for malignant neoplasms or fibrocystic changes without a distinct cyst.
