ICD-10-CM H81.92: Unspecified disorder of vestibular function, left ear

ICD-10-CM code H81.92 designates an unspecified disorder of vestibular function in the left ear, classified as a Disease or Syndrome under the parent code H81.9. This active terminology record provides the official label and hierarchy, while coverage articles and clinical guidelines offer separate operational context for vestibular function studies and rehabilitation. 1 4

Plain-language overview

Code H81.92 identifies an unspecified disorder of vestibular function affecting the left ear, and the terminology record classifies this concept as a Disease or Syndrome. 1

What this code represents

The H81.92 terminology record is active for the 2026 ICD-10-CM version and lists H81.9, the unspecified disorder of vestibular function, as its parent concept. 1

The exact code H81.92 appears alongside H81.93 for bilateral vestibular disorders in a Medicare billing and coding article covering vestibular and audiologic function studies. 4

Coding details

A phecode mapping resource groups the exact label for H81.92 with other left, right, bilateral, and unspecified ear vestibular function disorders, including vertiginous syndromes. 3

Documentation considerations

An audiology ICD-10-CM reference list notes that codes are included for information purposes only, the list is not exhaustive, and additional digits may exist beyond what is published. 5

Clinical context

A physical therapy clinical practice guideline focuses on peripheral vestibular hypofunction, noting its recommendations may not apply to individuals with central vestibular disorders. 2

What the sources add

While the terminology record defines the code hierarchy, the Medicare article provides billing context, and the physical therapy guideline adds clinical rehabilitation parameters for vestibular conditions. 1 4 2

The terminology record establishes the official code label and active status, whereas the phecode resource demonstrates how this exact diagnosis maps to broader vestibular disorder groupings. 1 3
