Code Description

ICD-10 D23.121 is a billable code used to indicate a diagnosis of other benign neoplasm of skin of left upper eyelid, including canthus.

Key Diagnostic Point:

D23.121 refers to a benign neoplasm located on the skin of the left upper eyelid, which may include the canthus area. Benign neoplasms of the skin can manifest as various types of growths, such as seborrheic keratosis, dermatofibromas, or other non-cancerous tumors. These lesions are typically asymptomatic but may cause cosmetic concerns or irritation, especially in sensitive areas like the eyelids. Diagnosis is usually made through clinical examination, and in some cases, a biopsy may be performed to confirm the benign nature of the lesion. Management often involves monitoring the growth, and if necessary, surgical excision may be performed for cosmetic reasons or if the lesion becomes symptomatic. Follow-up care is essential to ensure that the neoplasm does not recur and to monitor for any changes that may indicate a need for further intervention.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Specificity of location (left upper eyelid including canthus)
  • Differentiation from malignant neoplasms
  • Potential for multiple benign neoplasms in the same area
  • Need for precise documentation of size and characteristics

Audit Risk Factors

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