Valid for Submission
H81.91 is a billable diagnosis code used to specify a medical diagnosis of unspecified disorder of vestibular function, right ear. The code H81.91 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code H81.91 might also be used to specify conditions or terms like chronic right idiopathic vestibulopathy, dysfunction of right vestibular system, persistent right vestibulopathy following vestibular neuronitis, right vestibulopathy due to schwannoma or right vestibulopathy following medical intervention.
Unspecified diagnosis codes like H81.91 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Chronic right idiopathic vestibulopathy
- Dysfunction of right vestibular system
- Persistent right vestibulopathy following vestibular neuronitis
- Right vestibulopathy due to schwannoma
- Right vestibulopathy following medical intervention

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code H81.91 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Have you ever felt dizzy, lightheaded, or as if the room is spinning around you? If the feeling happens often, it could be a sign of a balance problem. Balance problems can make you feel unsteady. You may also have blurred vision, confusion, and disorientation. They are one cause of falls and fall-related injuries, such as a hip fracture.
Some balance problems are due to problems in the inner ear. Others may involve another part of the body, such as the brain or the heart. Aging, infections, head injury, certain medicines, or problems with blood circulation may also cause balance problems.
It is important to see your doctor about balance problems. They can be a sign of other health problems, such as an ear infection or a stroke. Your doctor may send you to a specialist for a diagnosis. You may need a hearing test, blood tests, or imaging studies of your head and brain. Other possible tests look at your eye movements, and how your body responds to movement.
In some cases, treating the illness that is causing the disorder will help with the balance problem. Exercises, a change in diet, and some medicines also can help.
