2026 ICD-10-CM Diagnosis Code H95.3 – Accidental puncture and laceration of ear and mastoid process during a procedure
What it is
This code identifies an accidental puncture or laceration involving the ear or mastoid process that occurs during a procedure. Use it when the injury is documented as a procedural complication, not a preexisting condition.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a recorded tear, perforation, or cut in the ear or mastoid area recognized during or after the procedure.
When to use this code
Use this code when the operative or procedure note states that the ear or mastoid process was accidentally punctured or lacerated. It fits iatrogenic injuries clearly linked to the procedure. Check documentation for the site, timing, and whether the event was accidental.
Do not use for
Do not use this code for intentional surgical incisions, routine operative access, or ear trauma unrelated to a procedure. Check documentation if the injury occurred before the procedure or from another cause.
Coding tip
Confirm that the record names both the complication and the procedure that caused it before assigning H95.3.
