Code Description

ICD-10 N63.11 is a billable code used to indicate a diagnosis of unspecified lump in the right breast, upper outer quadrant.

Key Diagnostic Point:

N63.11 refers to an unspecified lump located in the upper outer quadrant of the right breast. This code is often used when a patient presents with a palpable mass that has not been definitively diagnosed as benign or malignant. The differential diagnosis for breast lumps includes benign breast diseases such as fibroadenomas, cysts, and fibrocystic changes, as well as conditions like mastitis and breast hypertrophy. It is crucial to evaluate the lump through clinical examination and imaging studies, such as mammography or ultrasound, to determine its nature. In cases where the lump is associated with nipple discharge, further investigation is warranted to rule out underlying pathologies. Accurate coding requires thorough documentation of the clinical findings, imaging results, and any interventions performed. This code is particularly relevant in outpatient settings where patients may present for routine breast examinations or follow-ups after initial findings.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation of breast lumps
  • Need for comprehensive documentation to support diagnosis
  • Differential diagnosis may include both benign and malignant conditions
  • Potential for overlapping symptoms with other breast conditions

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to include imaging results in the medical record
  • Misclassification of the lump as benign without sufficient evidence
  • Lack of follow-up documentation for unresolved lumps
