Mastitis without abscess

This code represents inflammation of the breast tissue, typically characterized by pain, swelling, warmth, and redness, but without the formation of a localized collection of pus. It commonly affects lactating women but can also occur in non-lactating individuals.

Use this code when documentation clearly indicates mastitis without any mention or evidence of an abscess. This diagnosis is often supported by physical examination findings and patient symptoms consistent with inflammation of the breast.

• Differentiate carefully from mastitis with abscess (N61.1), which requires a different code.
• Specify laterality (e.g., N61.01 for right breast, N61.02 for left breast, N61.03 for bilateral) if documented.
• Consider an additional code for the underlying cause if known and documented (e.g., bacterial infection).
