Squamous cell carcinoma of skin of nose.
Medical necessity is based on the presence of a confirmed malignant skin lesion requiring treatment to prevent spread and further complications.
Diagnosis is based on history, symptoms, physical exam, biopsy, and imaging (CT/MRI). Treatment may include excision, curettage, cryosurgery, Mohs surgery, photodynamic therapy, chemotherapy, and radiotherapy.

- Malignant neoplasms (C00-C97)Malignant neoplasms, stated or presumed to be primary (of specified sites), and certain specified histologies, except neuroendocrine, and of lymphoid, hematopoietic and related tissue (C00-C75)Melanoma and other malignant neoplasms of skin (C43-C44)
In simple words: Skin cancer on the nose, specifically squamous cell carcinoma, is a type of cancer that starts in the outer layer of the skin. It appears as small, hard bumps or sores that don't heal and might bleed or scab. It is often caused by too much sun exposure or contact with certain chemicals.
Squamous cell carcinoma of skin of nose occurs due to uncontrolled multiplication of malignant cells deriving from the epithelium (the outer layer of skin) or showing cytology of squamous cell differentiation, which can invade nearby tissues and spread to lymph nodes, most commonly found in people with excessive exposure to sunlight or certain chemicals.
Example 1: A 65-year-old male with a history of prolonged sun exposure presents with a non-healing sore on his nose. Biopsy confirms squamous cell carcinoma., A 50-year-old female with a small, hard nodule on her nose undergoes excision. Pathology reveals squamous cell carcinoma., A 70-year-old male with a history of basal cell carcinoma develops a new lesion on his nose, diagnosed as squamous cell carcinoma via biopsy.
Documentation should include history of sun exposure or chemical exposure, physical exam findings (size, location, appearance of lesion), biopsy results, imaging reports (if applicable), and treatment details.
