About coding malignant positional vertigo
The ICD-10-CM code for malignant positional vertigo is H81.4 (Vertigo of central origin).
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.
