ICD-10 Code H94 – Other disorders of ear in diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H94 – Other disorders of ear in diseases classified elsewhere
What it is
H94 identifies ear disorders that are caused by another underlying disease, rather than a primary ear condition. Use it when the ear problem is documented as secondary to a separate, specified illness.
Clinical signs
Clinical features vary; refer to documentation. You may see hearing changes, ear discomfort, or other ear-related findings tied to the underlying disease process.
When to use this code
Use H94 when the record clearly states an ear disorder is due to another classified disease. Code the underlying condition first when required, and link the ear finding to that cause in the documentation.
If the note only describes a nonspecific ear complaint without a documented secondary cause, check documentation before assigning H94. You should avoid using it for primary ear diseases.
Do not use for
Do not use H94 for isolated ear disorders with no documented underlying disease. Do not use it when the condition is better classified as a primary ear diagnosis.
Coding tip
Confirm the causal disease is documented and sequenced correctly before you assign H94.
