Stomatitis is an oral condition referred to as inflamed and sore mouth. This is a type of mucositis, caused by inflammation of the mucous membrane. It can disrupt one’s ability to eat, talk, and sleep. It can occur anywhere in the mouth, including the inside of the cheeks, gums, tongue, lips, and palate. The treatment often focuses on managing the symptoms. Dentists treating this condition can rely on professional dental billing companies to get the dental claims submitted with the right diagnosis and procedure codes.

The types of stomatitis include canker sore or aphthous ulcer, cold sores or fever blisters and mouth irritation. While canker sores appear as ulcers in the mouth, usually on the cheeks, tongue, or inside the lip, cold sores appear as fluid-filled sores on or around the lips. At the same time, mouth irritation can be caused due to gum disease (gingivitis), chewing tobacco, oral inflammation and ulcers or any other type of mouth infection. Such sores can be caused by poor nutrition, stress, mouth injury, a weak immune system, lack of sleep, hormonal changes, or side effects of chemotherapy and sometimes radiotherapy. Depending on the area of the mouth affected, stomatitis can be broken down into different categories such as – cheilitis (inflammation of the lips and around the mouth), glossitis (inflammation of the tongue), gingivitis (inflammation of the gums) and pharyngitis (inflammation of the back of the mouth).

Common symptoms include mouth ulcers, red patches, swelling, lesions that heal in 4 days – two weeks. Treatment options for severe sores include Lidex gel, Aphthasol anti-inflammatory paste, Peridex mouthwash, and anti-inflammatory drugs like corticosteroids. To submit error-free medical claims, practices can consider partnering with an experienced dental billing service. Make sure that the coders are up to date with the changing coding standards.
