Code Description

ICD-10 D23.22 is a billable code used to indicate a diagnosis of other benign neoplasm of skin of left ear and external auricular canal.

Key Diagnostic Point:

D23.22 refers to a benign neoplasm located specifically on the skin of the left ear and the external auricular canal. These neoplasms can vary in appearance and may include conditions such as dermatofibromas, seborrheic keratosis, or other non-cancerous growths. Clinically, these lesions are typically asymptomatic but may present with cosmetic concerns or irritation. Diagnosis is often made through clinical examination, and in some cases, a biopsy may be performed to confirm the benign nature of the lesion. Management usually involves monitoring for changes in size or appearance, and surgical excision may be considered if the neoplasm becomes symptomatic or for cosmetic reasons. Follow-up care is essential to ensure that no malignant transformation occurs and to monitor for the development of new lesions.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Specificity of location (left ear and external auricular canal)
  • Differentiation from malignant neoplasms
  • Need for accurate documentation of lesion characteristics
  • Potential for multiple benign lesions requiring coding

Audit Risk Factors

  • Inadequate documentation of lesion characteristics
  • Failure to specify the exact location of the neoplasm
  • Misclassification as malignant neoplasm
  • Lack of follow-up documentation
