Unspecified benign mammary dysplasia of right breast

This code describes a non-cancerous, abnormal development of breast tissue in the right breast where the specific type of benign dysplasia is not documented. It indicates a general, unspecified alteration in the cellular and architectural structure of the mammary gland that is not malignant.

Use this code when the physician's documentation clearly states "benign mammary dysplasia" of the right breast but does not specify a more definitive type (e.g., fibrocystic changes, adenosis, epithelial hyperplasia). This code is appropriate when a biopsy or imaging report confirms benign changes but lacks further pathological detail.

• Ensure the documentation specifies the right breast; otherwise, use the unspecified laterality code.
• Avoid using this code if a more specific type of benign breast condition (e.g., fibrocystic disease, mastopathy) is documented; always code to the highest level of specificity.
• If bilateral involvement is noted, assign separate codes for each breast (e.g., N60.91 for right, N60.92 for left).
