About coding visual deprivation nystagmus
The ICD-10-CM code for visual deprivation nystagmus is H55.03 (Visual deprivation nystagmus).
Within H55.0 (nystagmus), H55.03 is specifically for visual deprivation nystagmus. Related codes cover unspecified nystagmus (H55.00), congenital nystagmus (H55.01), latent nystagmus (H55.02), dissociated nystagmus (H55.04) and other forms of nystagmus (H55.09).
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 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
