Basal cell carcinoma skin/ r ear and external auric canal

This code signifies a malignant neoplasm originating from the basal cells of the epidermis, specifically located on the skin of the right ear or within the external auditory canal. It represents the most common type of skin cancer, characterized by slow growth and rare metastasis.

Apply this code when documentation confirms a diagnosis of basal cell carcinoma affecting the right ear or external auditory canal. This typically follows a biopsy and pathological confirmation. Use for initial diagnosis, treatment, and follow-up care for this specific malignancy.

• Ensure laterality is clearly documented as "right ear" or "right external auditory canal."
• Do not use for squamous cell carcinoma or melanoma; these have distinct codes.
• Code any associated complications or secondary malignancies separately.
