Code Description

ICD-10 N65.1 is a billable code used to indicate a diagnosis of disproportion of reconstructed breast.

Key Diagnostic Point:

Disproportion of reconstructed breast refers to an imbalance in size, shape, or symmetry of a breast that has undergone surgical reconstruction, often following mastectomy or lumpectomy due to breast cancer or other conditions. This condition can arise from various factors, including the surgical technique used, the type of implant or tissue used for reconstruction, and the healing process. Patients may experience dissatisfaction with the aesthetic outcome, which can lead to psychological distress. The condition may also be associated with complications such as capsular contracture, asymmetry, or changes in breast tissue over time. Accurate diagnosis and coding are essential for appropriate management and potential corrective procedures. It is important for healthcare providers to document the specifics of the reconstruction, any complications, and the patient's concerns to ensure proper coding and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in surgical techniques and materials used for breast reconstruction.
  • Potential for complications that may alter the coding.
  • Need for detailed documentation of patient history and surgical outcomes.
  • Differentiation from other breast conditions such as hypertrophy or malignancy.

Audit Risk Factors

  • Inadequate documentation of surgical details and outcomes.
  • Failure to capture complications related to reconstruction.
  • Misclassification of breast conditions leading to incorrect coding.
  • Lack of patient-reported outcomes in medical records.
