Disorders of external ear in diseases classified elsewhere (H62)
The ICD-10 code section H62 is used to classify disorders of the external ear that occur as part of other diseases listed elsewhere in medical classification. This includes specific conditions like otitis externa related to other underlying diseases, with codes distinguishing the affected ear.
This section covers conditions such as otitis externa in other diseases classified elsewhere, which means inflammation or infection of the outer ear canal caused by diseases not primarily of the ear. Notably, the ICD-10 code for otitis externa is further specified by laterality: right ear (H62.41), left ear (H62.42), bilateral (H62.43), or unspecified ear (H62.40). For example, otitis externa of the right external auditory canal caused by human herpesvirus 3 is coded as H62.41. Additionally, other less common external ear disorders linked to systemic diseases are classified under codes starting with H62.8 and distinguished by affected side. This categorization helps medical coders accurately report ear conditions that arise secondary to diseases affecting other body systems.
