About H82.3

H82.3 is the ICD-10-CM diagnosis code for vertiginous syndromes in diseases classified elsewhere, bilateral. It belongs to category H82 (vertiginous syndromes in diseases classified elsewhere), 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 H82 (vertiginous syndromes in diseases classified elsewhere), H82.3 is specifically for vertiginous syndromes in diseases classified elsewhere, bilateral. Related codes cover right ear (H82.1), left ear (H82.2) and unspecified ear (H82.9).

Code first: underlying disease.

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 is a manifestation code, so it describes the effect of an underlying disease and can't be the principal diagnosis. Code the underlying condition first.

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 386.8 (other disorders of labyrinth).
