About coding Miners' nystagmus
The ICD-10-CM code for Miners' nystagmus is H55.09 (Other forms of nystagmus).
Within H55.0, choose H55.09 (Other forms of nystagmus) only when documentation doesn't support a more specific option: unspecified nystagmus (H55.00), congenital nystagmus (H55.01), latent nystagmus (H55.02), visual deprivation nystagmus (H55.03) and dissociated nystagmus (H55.04).
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.
