ICD-10 Code H62.8X9 – Other disorders of external ear in diseases classified elsewhere, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H62.8X9 – Other disorders of external ear in diseases classified elsewhere, unspecified ear
What it is
This code identifies a disorder of the external ear that is caused by another underlying disease, but the ear side is not specified. Use it when the documentation links the ear condition to a separate classified illness.
Clinical signs
Clinical features vary; refer to documentation. Findings may include external ear inflammation, irritation, swelling, pain, or other ear changes noted as secondary to an underlying condition.
When to use this code
Use this code when the provider documents an external ear disorder that is secondary to a disease classified elsewhere and does not identify the affected ear. It fits records that clearly connect the ear problem to another condition. If the note names the ear, code the laterality instead.
Do not use for
Do not use this code for primary external ear disorders with no underlying cause documented. Also avoid it when the chart specifies a more exact ear side or a different diagnosis, such as a localized infection or trauma.
Coding tip
Check the underlying disease first, then confirm whether the ear side is documented before selecting this unspecified-ear code.
