Vertigo is a sensation of feeling off balance that often comes with symptoms such as vomiting, headache, sweating, spinning, going unbalanced, or pulled to one direction. Even though the main cause of the condition is related to issues with the inner ear balance, it can also be triggered by certain head movements or benign paroxysmal positional vertigo (BPPV), migraines, inner ear infection (labyrinthitis) or inflammation of the vestibular nerve (vestibular neuronitis). Otolaryngologists and neurologists can ensure accurate medical coding for vertigo on their medical claims with the support of an experienced medical coding company.

    ICD-10 Codes to Indicate Diagnostic Studies for Vertigo

    Along with physical examination, other tests used to diagnose the condition include hearing tests done by an ENT specialist such as audiometry test, tuning fork test, videonystagmography, caloric testing, dynamic or static platform posturography, and CT or MRI scan of head.

      • Z01.118 Encounter for examination of ears and hearing with other abnormal findings
      • Z01.12 Encounter for hearing conservation and treatment
    • R94.12 Abnormal results of function studies of ear and other special senses
      • R94.120 Abnormal auditory function study
      • R94.121 Abnormal vestibular function study
      • R94.128 Abnormal results of other function studies of ear and other special senses

    Some of the effective treatments recommended to treat vertigo symptoms include Epley maneuver, and vestibular rehabilitation training (VRT). Medications such as prochlorperazine and certain antihistamines may be recommended in the early stages of vertigo. In rare cases, surgery may be needed.

    ENT specialists, neurologists and other specialists treating vertigo conditions can consider hiring professional medical coding services to ensure accurate medical coding and prevent claim denials.
