About coding Hemeralopia
The ICD-10-CM code for Hemeralopia is H53.11 (Day blindness). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on H53.11.
Within H53.1 (subjective visual disturbances), H53.11 is specifically for day blindness. Related codes cover unspecified subjective visual disturbances (H53.10), transient visual loss (H53.12), sudden visual loss (H53.13), visual discomfort (H53.14), visual distortions of shape and size (H53.15), Psychophysical visual disturbances (H53.16) and other subjective visual disturbances (H53.19).
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.
