Code Description

ICD-10 C03 is a billable code used to indicate a diagnosis of malignant neoplasm of gum.

Key Diagnostic Point:

Malignant neoplasm of the gum, classified under ICD-10 code C03, refers to cancerous growths that originate in the gum tissue of the oral cavity. This condition can manifest as squamous cell carcinoma, which is the most common type of oral cancer affecting the gums. Patients may present with symptoms such as persistent swelling, pain, or ulceration in the gum area, which can lead to difficulty in chewing or swallowing. Diagnosis typically involves a thorough clinical examination, imaging studies, and biopsy to confirm malignancy. Treatment options may include surgical excision, radiation therapy, and chemotherapy, depending on the stage and extent of the disease. Multidisciplinary care is crucial, involving oncologists, oral surgeons, dentists, and nutritionists to address the comprehensive needs of the patient, including pain management and nutritional support. Regular follow-ups are essential to monitor for recurrence and manage any treatment-related complications.
