About coding joint xanthoma
The ICD-10-CM code for joint xanthoma is E75.5 (Other lipid storage disorders).
Within E75, choose E75.5 (Other lipid storage disorders) only when documentation doesn't support a more specific option: GM2 gangliosidosis (E75.0), other and unspecified gangliosidosis (E75.1), other sphingolipidosis (E75.2), sphingolipidosis, unspecified (E75.3), Neuronal ceroid lipofuscinosis (E75.4) and lipid storage disorder, unspecified (E75.6).
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.
