ICD-10 Code H95.191 – Other disorders following mastoidectomy, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.191 – Other disorders following mastoidectomy, right ear
What it is
This code identifies a postoperative disorder affecting the right ear after mastoidectomy. Use it when the chart documents a complication or residual problem linked to the surgery, but not a more specific coded condition.
Clinical signs
Clinical features vary; refer to documentation. You may see persistent ear symptoms, abnormal postoperative findings, or a noted mastoidectomy-related disorder on the right side.
When to use this code
Use H95.191 when the provider documents a right-ear disorder occurring after mastoidectomy and no more specific postoperative code applies. It is appropriate for residual or unspecified postoperative problems tied to the surgery. Check documentation for laterality and whether the condition is truly postoperative.
Do not use for
Do not use this code for routine postoperative status without a complication, or for a different ear side. If the record names a specific postoperative complication, code that condition instead.
Coding tip
Verify that the note links the disorder to mastoidectomy and confirms the right ear before assigning H95.191.
