About coding dermatoarthritis
The ICD-10-CM code for dermatoarthritis is E78.81 (Lipoid dermatoarthritis).
Within E78.8 (other disorders of lipoprotein metabolism), E78.81 is specifically for lipoid dermatoarthritis. Related codes cover other lipoprotein metabolism disorders (E78.89).
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.
