ICD-10 Code H93.91 – Unspecified disorder of right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.91 – Unspecified disorder of right ear
What it is
H93.91 identifies a disorder of the right ear that is not otherwise specified in the record. Use it when the documentation confirms a right ear problem but does not name a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may note right ear pain, fullness, hearing change, or other ear-related abnormal findings without a definitive labeled condition.
When to use this code
Use this code when the provider documents an unspecified disorder affecting the right ear and no more specific ICD-10-CM diagnosis is available. It may apply to incomplete assessments, vague ear complaints, or follow-up notes that still lack a clear diagnosis.
Choose the most specific right-ear code if the record later identifies otitis, hearing loss, tinnitus, or another defined condition. Check documentation for laterality and for any more detailed ear diagnosis.
Do not use for
Do not use H93.91 when the condition is documented as a specific ear disorder or when the left ear, bilateral ears, or ear canal is clearly identified. Check documentation.
Coding tip
Assign H93.91 only after confirming right-sided laterality and the absence of a more specific diagnosis in the note.
