What is canker sores icd 10?

Canker sores are also known as aphthous ulcers. The ICD-10 code for canker sores is K12.0. Canker sores are common and usually heal without treatment. They are painful, round or oval-shaped sores that form inside the mouth, typically on the tongue, inner cheek, or lip. Canker sores can be caused by a variety of factors, including stress, injury, and certain foods. They may also be a symptom of an underlying condition such as celiac disease or Crohn's disease. However, in most cases, canker sores are harmless and do not require medical attention. Symptomatic treatment with topical anesthetics or anti-inflammatory agents can be helpful in reducing pain and promoting healing.
