Code Classification

  • Diseases of the ear and mastoid process
    (H60–H95)
    • Diseases of inner ear
      (H80-H83)
      • Disorders of vestibular function
        (H81)

H81.93 is a billable diagnosis code used to specify a medical diagnosis of unspecified disorder of vestibular function, bilateral. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like H81.93 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.

Patient Education


Balance Problems

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 (broken hip).

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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
