ICD-10 Code H95.42 – Postprocedural hemorrhage of ear and mastoid process following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H95.42 – Postprocedural hemorrhage of ear and mastoid process following other procedure
What it is
H95.42 identifies bleeding that occurs after a procedure involving the ear or mastoid process. Use it when the record clearly links the hemorrhage to a prior intervention rather than to trauma or a spontaneous ear condition.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include postoperative bleeding, oozing, or hematoma at the operative site, with the provider documenting the ear or mastoid process as the source.
When to use this code
Use H95.42 when the provider documents postprocedural hemorrhage after an ear or mastoid procedure and the complication is not classified elsewhere. It is appropriate for follow-up notes, discharge summaries, or complication reports that identify bleeding as a procedure-related event. Check documentation for the exact procedure and site.
Do not use for
Do not use this code for bleeding unrelated to a procedure, such as trauma or infection. If the record does not clearly state a postprocedural ear or mastoid hemorrhage, check documentation.
Coding tip
Assign the complication code only when the provider explicitly documents the hemorrhage as postprocedural and names the ear or mastoid site.
