About coding Lenticular degeneration
The ICD-10-CM code for Lenticular degeneration is E83.01 (Wilson's disease).
Within E83.0 (disorders of copper metabolism), E83.01 is specifically for Wilson's disease. Related codes cover disorder of copper metabolism, unspecified (E83.00) and other disorders of copper metabolism (E83.09).
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 642 (Inborn and Other Disorders of Metabolism, relative weight 1.3219), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
