Code Description

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

Key Diagnostic Point:

Deformity and disproportion of the reconstructed breast refers to the abnormal shape or size of a breast that has undergone surgical reconstruction, often following mastectomy due to cancer or other conditions. This deformity can arise from various factors, including inadequate tissue expansion, complications during the healing process, or the use of implants that do not match the natural breast's contour. Patients may experience psychological distress due to the aesthetic outcomes of their reconstruction, which can impact their quality of life. The condition may also be associated with benign breast diseases such as mastitis, which can complicate the healing process, or breast hypertrophy, which may necessitate further surgical intervention. Accurate coding requires a thorough understanding of the patient's surgical history, the nature of the deformity, and any associated conditions that may influence treatment options. Documentation should detail the specifics of the reconstruction, any complications encountered, and the patient's overall health status to ensure appropriate coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in surgical techniques and outcomes
  • Need for detailed documentation of prior surgeries
  • Potential for associated conditions (e.g., mastitis, hypertrophy)
  • Subjectivity in assessing deformity and disproportion

Audit Risk Factors

  • Inadequate documentation of surgical history
  • Failure to specify the type of reconstruction performed
  • Misclassification of deformity severity
  • Lack of correlation between diagnosis and treatment provided

Specialty Focus

Medical Specialties

Plastic Surgery

Documentation Requirements

Detailed operative reports, pre-operative assessments, and post-operative follow-ups are essential for accurate coding.

Common Clinical Scenarios

Reconstruction after mastectomy, correction of asymmetry, and management of complications.

Billing Considerations

Documenting the specific type of reconstruction (e.g., flap vs. implant) and any complications encountered is crucial.

Oncology

Documentation Requirements

Comprehensive cancer treatment history, including mastectomy details and any adjuvant therapies.

Common Clinical Scenarios

Patients undergoing reconstruction post-mastectomy due to breast cancer.

Billing Considerations

Understanding the oncological context is vital for accurate coding and treatment planning.

Coding Guidelines

Inclusion Criteria

Use N65 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the code is used only when deformity and disproportion are documented as a result of reconstruction

Exclusion Criteria

Do NOT use N65 When
  • Exclude conditions that do not pertain to surgical outcomes
