Granulomatous mastitis, right breast

This code signifies a chronic inflammatory condition of the right breast characterized by the formation of granulomas, which are collections of immune cells. It is a non-infectious process that can mimic other breast pathologies, including carcinoma. The condition often presents with palpable masses, pain, and skin changes.

Apply this code when documentation explicitly states a diagnosis of granulomatous mastitis affecting the right breast. This diagnosis is typically confirmed through biopsy demonstrating granulomatous inflammation without evidence of infection or malignancy. Use this code for initial diagnosis and subsequent encounters related to the management of this specific condition.

• Ensure laterality is clearly documented as "right breast" to support this specific code.
• Distinguish from other forms of mastitis (e.g., infectious, periductal) which have different codes.
• Do not code suspected granulomatous mastitis; wait for definitive diagnostic confirmation.
