Postproc hematoma of ear/mastd following other procedure

This code signifies a collection of blood (hematoma) that forms in the ear or mastoid region as a complication after a surgical or invasive procedure, other than those specifically involving the ear or mastoid. It indicates a post-operative bleeding event occurring in the anatomical area of the ear and/or mastoid process.

Use this code when documentation clearly states a hematoma developed in the ear or mastoid area following a non-otologic surgical procedure. Examples include a hematoma after a facelift, parotidectomy, or other head and neck surgery where the ear/mastoid region was incidentally affected by bleeding. The physician's notes should explicitly link the hematoma to the "other procedure."

• Ensure the documentation specifies the hematoma is postprocedural and located in the ear and mastoid process.
• Verify the primary procedure was not an ear or mastoid procedure; if it was, a more specific complication code would apply.
• Sequence this code after the code for the underlying condition or reason for the original procedure, if applicable, or as a secondary diagnosis indicating a complication.
