About coding hallucinations vision
The ICD-10-CM code for hallucinations vision is R44.1 (Visual hallucinations).
Within R44 (other symptoms and signs involving general sensations and perceptions), R44.1 is specifically for visual hallucinations. Related codes cover auditory hallucinations (R44.0), other hallucinations (R44.2), hallucinations, unspecified (R44.3), other symptoms and signs involving general sensations and perceptions (R44.8) and unspecified symptoms and signs involving general sensations and perceptions (R44.9).
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 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.
