    ICD-10-CM Code For Benign Neoplasm Of Mouth And Pharynx: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group D10 includes benign neoplasms of the oral cavity and pharynx, covering nonmalignant tumors such as papillomas, fibromas, and other localized growths of the tongue, gum, floor of mouth, buccal mucosa, and oropharynx. These ICD-10-CM diagnosis codes are used to document site-specific benign tumors of the mouth and throat, capturing lesion location and morphology relevant to treatment and follow-up. Accurate coding within the ICD-10-CM D10 group supports proper claim adjudication and complete clinical documentation.

    Typical Clinical Scenarios

    • An adult patient presents to the outpatient ENT clinic with a several-month history of a painless, slowly enlarging lump on the lateral border of the tongue causing mild speech interference but no dysphagia. Examination shows a discrete, well-circumscribed submucosal mass consistent with a benign salivary gland or mesenchymal tumor of the tongue; imaging and planned excisional biopsy are scheduled and a benign neoplasm diagnosis of the oral cavity is assigned. Typical codes: D10.2
    • A pediatric patient is referred to pediatric dentistry for a pedunculated growth on the hard palate noted since infancy that has increased in size and intermittently bleeds with feeding. The lesion has features consistent with a benign tumor of the mouth requiring evaluation and possible surgical removal under anesthesia, so a benign neoplasm code specific to the palate is used. Typical codes: D10.1, D10.0
    • An adult smoker presents to the emergency department with acute airway compromise from a rapidly enlarging mass in the oropharynx causing dysphagia and partial airway obstruction; urgent assessment reveals a previously undiagnosed benign neoplasm of the pharynx that has become complicated by secondary infection and edema. The admission diagnosis documents a benign pharyngeal neoplasm as a comorbid condition guiding surgical and airway management. Typical codes: D10.3, D10.39}
