Fibrosclerosis of unspecified breast

This code represents a non-malignant condition characterized by an abnormal increase in fibrous connective tissue within the breast, without further specification of the particular type of fibrosclerosis. It indicates a generalized hardening or scarring of breast tissue due to excessive collagen deposition.

Use this code when documentation specifies "fibrosclerosis of breast" without further detail regarding the specific type (e.g., focal, diffuse, or periductal). This diagnosis is often made based on imaging findings (mammography, ultrasound) or biopsy results showing increased fibrous tissue.

• Ensure documentation clearly states "fibrosclerosis" and lacks further specificity for laterality or type.
• Do not use if a more specific type of fibrocystic change or benign mammary dysplasia is documented.
• Consider sequencing with codes for associated symptoms like breast pain (mastalgia) if documented.
