Other congenital malformations of breast

This code represents various congenital structural abnormalities of the breast that are not specifically classified elsewhere. These malformations are present at birth and can affect the size, shape, or development of the breast tissue, nipple, or areola. Examples include accessory breast tissue (polymastia) or absence of the nipple (athelia) without complete absence of the breast.

Use this code when documentation specifies a congenital breast malformation that is not aplasia, hypoplasia, or hypertrophy. This code is appropriate for conditions like supernumerary breasts or nipples, or other specified developmental anomalies of the breast. Ensure the medical record clearly identifies the condition as congenital and details the specific malformation.

• Differentiate from Q83.0 (Amastia), Q83.1 (Supernumerary breasts), Q83.2 (Hypoplasia of breast), and Q83.3 (Accessory nipple).
• Always review the physician's documentation for precise terminology regarding the specific congenital breast anomaly.
• If the malformation is part of a recognized syndrome, code the syndrome first, followed by this code if the breast anomaly is a significant component.
