About H81.313

H81.313 is the ICD-10-CM diagnosis code for Aural vertigo, bilateral. It belongs to category H81 (disorders of vestibular function), block H80-H83 (diseases of inner ear) and chapter 8 (diseases of the ear and mastoid process). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within H81.31 (Aural vertigo), H81.313 is specifically for Aural vertigo, bilateral. Related codes cover right ear (H81.311), left ear (H81.312) and unspecified ear (H81.319).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 149 (Dysequilibrium, relative weight 0.7527), in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 386.19 (other peripheral vertigo).
