Other disorders of external ear (H61)

The ICD-10 code section H61 covers a range of disorders affecting the external ear, including conditions like perichondritis, chondritis, acquired deformities, impacted cerumen, stenosis, and other specified or unspecified external ear problems. These codes are used to classify different types of ear disorders for diagnosis and treatment documentation.

This section addresses various disorders of the external ear such as perichondritis (inflammation of the ear's cartilage) and chondrodermatitis nodularis helicis, known by synonyms like "perichondritis of pinna" and used under codes like H61.001 and H61.002. It also includes noninfective disorders of the pinna, including acquired deformities often related to ear piercing complications (e.g., "acquired split lobe") coded under H61.111–H61.113. Impacted cerumen, or earwax buildup, is identified by H61.2. Acquired narrowing (stenosis) of the external ear canal due to trauma or infection appears under H61.31 and H61.32. Additionally, exostosis, which is bony growth in the ear canal, and other specified conditions like polyps are included. Knowledge of these specific ICD-10 codes helps ensure precise medical coding for external ear disorders.
