Intraop hemor/hemtom of ear/mastd comp a proc on ear/mastd

This code signifies the occurrence of bleeding or a collection of blood (hematoma) within the ear or mastoid process that arises during a surgical procedure performed on these structures. It specifically identifies an adverse event that complicates the ongoing surgical intervention.

This code is appropriate when documentation clearly indicates intraoperative hemorrhage or hematoma occurring during a procedure such as a mastoidectomy, tympanoplasty, or stapedectomy. The operative report should detail the bleeding event, its management, and its impact on the procedure.

• Requires a primary code for the underlying ear or mastoid condition being treated.
• Ensure documentation specifies "intraoperative" to differentiate from postoperative complications.
• Do not use for anticipated minor bleeding that is part of the normal surgical process and easily controlled without significant intervention.
