Understanding Wandering Rash of the Mouth (ICD-11 DA01.02)

Wandering rash of the mouth, identified by the ICD-11 code DA01.02, is a benign inflammatory condition affecting the oral epithelium. It is considered a counterpart to geographic tongue but typically manifests on other parts of the oral mucosa rather than the tongue's surface. This condition is characterized by its chronic, relapsing nature and an unknown etiology. While less common than geographic tongue, it presents a similar pattern of migratory lesions.

Signs of Oral Erythema Migrans

The primary presentation of wandering rash of the mouth involves the appearance of smooth, reddish patches on the oral mucosa. These patches are often irregular in shape and can vary in size. A key characteristic is their migratory nature, meaning they can change location, size, or shape over time, sometimes within hours. While generally harmless, these lesions may occasionally cause mild discomfort or increased sensitivity to certain foods, though many individuals experience no noticeable symptoms.

How Wandering Rash of the Mouth is Diagnosed

Diagnosis of wandering rash of the mouth (ICD-11 DA01.02) is primarily based on a clinical examination and the patient's medical history. Healthcare professionals observe the characteristic appearance and migratory pattern of the lesions on the oral mucosa. Histological confirmation is rarely required, as the visual presentation is typically distinctive enough for a diagnosis.

Common Synonyms for Wandering Rash of the Mouth

This condition is known by several alternative terms, reflecting its appearance and migratory behaviour. Common synonyms include oral erythema migrans, geographic stomatitis, migratory stomatitis, and ectopic geographic tongue. It is also sometimes referred to as a wandering rash of the tongue, though the ICD-11 code DA01.02 specifically denotes its occurrence on other oral mucosal surfaces.

ICD-11 Code DA01.02: Wandering Rash of the Mouth for Billing

The ICD-11 code DA01.02 serves as the official classification for Wandering rash of the mouth. This code is essential for accurate medical documentation, billing, and statistical tracking of this specific oral condition. It falls under the broader category of Disturbances of oral epithelium within the ICD-11 system.
