Code Description

ICD-10 N64.52 is a billable code used to indicate a diagnosis of nipple discharge.

Key Diagnostic Point:

Nipple discharge refers to the secretion of fluid from the nipple, which can occur in both men and women. This condition can be benign or indicative of underlying pathology. Common causes include hormonal changes, benign breast diseases such as fibrocystic changes, and infections like mastitis. Discharge can be unilateral or bilateral and may vary in color and consistency, ranging from clear to bloody. In women, nipple discharge is often associated with conditions such as galactorrhea, which is the inappropriate lactation due to hormonal imbalances, or duct ectasia, where a milk duct beneath the nipple dilates and fills with fluid. Infections like mastitis can lead to purulent discharge and are often accompanied by pain and swelling. Breast imaging, including mammography and ultrasound, is crucial in evaluating nipple discharge, especially when associated with a palpable mass or concerning characteristics. The clinical evaluation should include a thorough history and physical examination to determine the nature of the discharge and guide further diagnostic steps.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes (benign vs. malignant)
  • Need for thorough documentation of discharge characteristics
  • Differentiation between types of discharge (spontaneous vs. expressed)
  • Potential for co-existing conditions (e.g., mastitis, breast lumps)

Audit Risk Factors

  • Inadequate documentation of discharge characteristics
  • Failure to document associated symptoms (pain, swelling)
  • Misclassification of discharge type (spontaneous vs. expressed)
  • Lack of imaging results in the medical record

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of nipple discharge, improving the ability to capture the nuances of this condition and its underlying causes. This specificity aids in better tracking of patient outcomes and resource allocation.

ICD-9 vs ICD-10
