About coding vestibular function disorder
The ICD-10-CM code for vestibular function disorder is H81.9 (Unspecified disorder of vestibular function). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on H81.9.
Within H81, choose H81.9 (Unspecified disorder of vestibular function) only when documentation doesn't support a more specific option: Meniere's disease (H81.0), benign paroxysmal vertigo (H81.1), vestibular neuronitis (H81.2), other peripheral vertigo (H81.3), vertigo of central origin (H81.4) and other disorders of vestibular function (H81.8).
To report this condition, pick the subcode that matches the documentation: H81.90 (unspecified ear), H81.91 (right ear), H81.92 (left ear) and H81.93 (bilateral).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
