Inflammatory disease of breast

This code signifies a non-specific inflammatory process affecting the breast tissue. It encompasses various conditions characterized by inflammation, redness, swelling, and pain in the breast, excluding those with a clear infectious etiology or neoplastic origin.

Use this code for documented cases of mastitis (non-puerperal), breast abscess (without specified organism), or other inflammatory conditions of the breast where a more specific diagnosis is not established. Documentation should clearly indicate inflammation of the breast without further specification of cause or type.

• Do not use for infectious mastitis (e.g., puerperal mastitis or mastitis due to a specified organism); instead, code to the specific infection.
• Distinguish from benign mammary dysplasia (fibrocystic changes) unless inflammation is a primary component.
• Always review documentation for underlying causes or more specific diagnoses that would warrant a different code.
