Code Description

ICD-10 C44.112 is a billable code used to indicate a diagnosis of basal cell carcinoma of skin of right eyelid, including canthus.

Key Diagnostic Point:

Basal cell carcinoma (BCC) is the most common form of skin cancer, arising from the basal cells in the epidermis. This specific code, C44.112, refers to BCC located on the skin of the right eyelid, including the canthus, which is the corner of the eye where the upper and lower eyelids meet. BCC is typically associated with prolonged sun exposure, making it prevalent in individuals with fair skin or those who have had significant UV exposure over their lifetime. Clinically, BCC may present as a pearly or waxy bump, a flat, flesh-colored lesion, or a scar-like area. Surgical excision is the primary treatment, with the goal of achieving clear surgical margins to minimize recurrence. Reconstruction may be necessary depending on the size and location of the excised lesion, particularly in cosmetically sensitive areas like the eyelid. Proper coding requires detailed documentation of the lesion's characteristics, treatment performed, and any reconstructive procedures undertaken.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Location specificity (right eyelid, including canthus)
  • Need for detailed surgical documentation
  • Potential for reconstruction coding
  • Differentiation from other skin cancers

Audit Risk Factors

  • Inadequate documentation of surgical margins
  • Failure to document the specific location of the carcinoma
  • Lack of clarity on reconstruction procedures performed
  • Misclassification of skin cancer type

Frequently Asked Questions

What is the primary treatment for basal cell carcinoma?

The primary treatment for basal cell carcinoma is surgical excision, often using Mohs micrographic surgery to ensure clear margins. Other treatments may include topical chemotherapy or radiation therapy, depending on the case.
