    Typical Clinical Scenarios

    • A middle-aged patient presents to urgent care with a sudden onset of severe tongue pain, swelling, and difficulty speaking after biting the lateral tongue during a seizure. Examination shows a laceration with localized hematoma and erythema but no signs of systemic infection; a diagnosis from this group is assigned to capture the traumatic lesion of the tongue. Typical codes: K14.2.
    • An adult with a several-month history of a painful, persistent ulcer on the lateral border of the tongue that has not healed despite conservative care is referred to ENT for biopsy; pathology shows squamous cell carcinoma. A diagnosis from this group is used to document the malignant neoplasm of the tongue as the primary oral cancer site in oncology staging and treatment planning. Typical codes: K14.0, K14.1.
    • An elderly patient with advanced Parkinson disease develops a chronic, indurated, fissured tongue with recurring episodes of glossitis and secondary candidal overgrowth, contributing to poor oral intake and weight loss; the tongue changes are documented as a chronic tongue disorder complicating the neurologic condition. Typical codes: K14.4, K14.5.
