Intraoperative and postprocedural complications and disorders of ear and mastoid process, not elsewhere classified (H95)

The ICD-10 codes in the H95 section are used to classify complications and disorders that occur intraoperatively or after procedures involving the ear and mastoid process. These codes specifically cover unexpected issues following mastoidectomy surgeries and other ear-related interventions.

This section includes codes for recurring cholesteatomas of the postmastoidectomy cavity, described by terms like “mastoid cholesteatoma” or “recurrent cholesteatoma of mastoid cavity”, which correspond to codes H95.0–H95.03. It also captures chronic inflammation (chronic mastoiditis) and granulation tissue in the mastoid cavity, with codes H95.11–H95.13, helping coders identify conditions like “chronic right mastoiditis” or “granulation of left mastoid cavity”. Intraoperative hemorrhage, accidental puncture, and postprocedural hemorrhage or hematoma of the ear are documented with codes from H95.2–H95.5. Additional codes cover postprocedural complications such as stenosis of the external ear canal (e.g., “stenosis of right external ear canal due to procedure”, H95.811) and other rare or unspecified disorders, facilitating precise recording of complications following ear surgeries. This makes the ICD-10 code for postprocedural complications of the ear and mastoid process vital for accurate diagnosis and treatment documentation.
