Nonpurulent mastitis associated with the puerperium

This code signifies inflammation of the breast tissue, specifically non-infectious mastitis, occurring during the postpartum period (puerperium). It indicates an inflammatory process without evidence of pus formation or bacterial infection.

Apply this code when documentation specifies mastitis developing after childbirth, and the provider explicitly states it is nonpurulent or non-infectious. This typically involves symptoms like breast pain, swelling, redness, and warmth, without fever or signs of abscess.

• Ensure documentation clearly distinguishes between purulent and nonpurulent mastitis; if purulent, a different code is required.
• Confirm the mastitis occurred during the puerperal period; otherwise, a code from the N61 category (Inflammatory disorders of breast) would be more appropriate.
• Do not use this code for mastitis occurring during lactation but outside the puerperium.
