Nonpurulent mastitis associated w pregnancy, unsp trimester

This code describes inflammation of the breast tissue, specifically non-purulent (without pus formation), that occurs during pregnancy. It indicates a sterile inflammatory process rather than an infectious one, which is distinct from mastitis with abscess formation.

Use this code when documentation specifies mastitis occurring during pregnancy, and explicitly states it is nonpurulent. This typically applies to cases of inflammatory mastitis without signs of bacterial infection or abscess. The documentation should clearly link the mastitis to the pregnancy.

• Ensure documentation specifies "nonpurulent" to differentiate from infectious or abscess-forming mastitis.
• Do not use if the mastitis is explicitly stated to be puerperal (postpartum) or associated with lactation, as separate codes exist for those scenarios.
• This code is for an unspecified trimester; if the trimester is documented, a more specific code should be used.
