About the H95 Code Range
ICD-10-CM category H95 includes codes for complications and disorders that happen during or after ear and mastoid surgeries, which are not classified elsewhere. These codes capture issues such as recurrent cholesteatoma, chronic inflammation, hemorrhage, accidental injury, hematoma, seroma, and stenosis, among others.
This category specifically tracks complications that follow procedures like mastoidectomy, with detailed codes specifying the affected ear (right, left, bilateral, or unspecified). For example, recurrent cholesteatoma (also known as mastoid cholesteatoma) and chronic inflammation of the postmastoidectomy cavity are clearly documented under codes H95.0 and H95.11 respectively. Other codes cover intraoperative hemorrhage (H95.2), accidental punctures (H95.3), and postprocedural hematomas (H95.5). Additionally, stenosis of the external ear canal, sometimes called auditory system complications post-surgery, is coded in H95.81 series. This range is critical for accurately identifying and managing ear and mastoid surgical complications, including rare problems like postprocedural profound sensorineural hearing loss referenced under H95.89.
