Name of the Condition

• Squamous Cell Carcinoma of Skin of Left Upper Limb, Including Shoulder
• Commonly referred to as non-melanoma skin cancer.

Summary

Squamous cell carcinoma (SCC) is a form of skin cancer that arises from the squamous cells, which are flat cells located on the surface of the skin. When it occurs on the left upper limb, including the shoulder, it can present as a persistent, scaly patch or a growing lump. While often treatable, it can be aggressive if not managed promptly.

Causes

• Prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds.
• DNA mutations in skin cells.
• Smoking.

Risk Factors

• Age, particularly being over 50.
• Fair skin, light hair, and eye color.
• A history of excessive sun exposure or previous sunburns.
• A weakened immune system.

Symptoms

• A rough, scaly patch that may crust or bleed.
• A wart-like growth or persistent sore.
• A firm, red nodule.

Diagnosis

• Physical examination by a dermatologist.
• Skin biopsy to check for cancerous cells.
• Additional imaging, if the extent of spread needs assessment.

Treatment Options

• Surgical excision to remove cancerous tissue.
• Mohs micrographic surgery for precise removal.
• Radiation therapy for non-surgical candidates.
• Topical chemotherapies or photodynamic therapy for superficial SCC.

Prognosis and Follow-Up

• Early detection and treatment result in a high cure rate.
• Regular follow-up is crucial to prevent recurrence and monitor for new lesions.
• Prognosis depends on the stage at diagnosis and the effectiveness of treatment.

Complications

• Potential for local tissue destruction and disfigurement.
• Risk of metastasis to lymph nodes or other organs if untreated or aggressive.

Lifestyle & Prevention

• Regular use of broad-spectrum sunscreen and protective clothing.
• Avoid tanning beds and seek shade during peak sun hours.
• Routine skin checks for new or changing lesions.

When to Seek Professional Help

• Noticeable changes in size, shape, or color of a skin lesion.
• Non-healing sores or growths.
• Persistent itching or irritation of a skin patch.

Tips for Medical Coders

• Ensure the specific location (left upper limb, including shoulder) is documented for accurate coding.
• Verify if additional codes are required for any metastatic sites.
• Be vigilant about distinguishing SCC from other types of skin cancer.
