Tympanosclerosis, unspecified ear

This code represents a condition characterized by the formation of hyalinized and often calcified connective tissue within the middle ear, eardrum, or mastoid, leading to thickening and reduced mobility. It is a non-inflammatory process that can result in conductive hearing loss. This specific code is used when the affected ear is not specified in the documentation.

Use this code when the physician documents "tympanosclerosis" without specifying laterality (e.g., right, left, or bilateral). Documentation should clearly indicate the presence of tympanosclerosis, often identified during otoscopic examination or surgical exploration. This code is appropriate when the provider does not specify the exact location or extent of the tympanosclerosis within the middle ear structures.

• Do not use this code if the documentation specifies the affected ear (e.g., H74.01 for right ear, H74.02 for left ear, H74.03 for bilateral).
• Consider if an associated conductive hearing loss (H90.0x or H90.1x) should also be coded, if documented.
• Ensure the medical record supports the diagnosis of tympanosclerosis, typically through clinical findings or surgical reports.
