Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the H80 range.
Otosclerosis
Formation of spongy bone in the labyrinth capsule which can progress toward the STAPES (stapedial fixation) or anteriorly toward the COCHLEA leading to conductive, sensorineural, or mixed HEARING LOSS. Several genes are associated with familial otosclerosis with varied clinical signs.
About the H80 Code Range
ICD-10 code section H80 covers various types of otosclerosis, a condition affecting the bones of the middle ear which can lead to hearing loss. These codes differentiate otosclerosis by location, type, and laterality to provide precise diagnosis coding.
This section details codes like H80.0 for nonobliterative otosclerosis involving the oval window, with subcodes for the right, left, bilateral, or unspecified ear. In contrast, H80.1 refers to the obliterative type of otosclerosis at the oval window. Another subtype, cochlear otosclerosis coded under H80.2, involves the otic capsule or round window and is linked with synonyms such as “otosclerosis involving round window” or “cochlear otosclerosis.” The section also includes H80.8 for other forms like labyrinthitis ossificans, and H80.9 for unspecified otosclerosis cases, often referred to as “otosclerosis of the middle ear.” These distinctions help medical coders select the correct ICD-10 code for precise documentation of otosclerosis cases based on disease characteristics and ear involvement.
