About H81.4

H81.4 is the ICD-10-CM diagnosis code for vertigo of central origin. 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 (disorders of vestibular function), H81.4 is specifically for vertigo of central origin. Related codes cover Meniere's disease (H81.0), benign paroxysmal vertigo (H81.1), vestibular neuronitis (H81.2), other peripheral vertigo (H81.3), other disorders of vestibular function (H81.8) and unspecified disorder of vestibular function (H81.9).

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 changed in FY2020 (billable).
