About coding Zellweger's syndrome
The ICD-10-CM code for Zellweger's syndrome is E71.510 (Zellweger syndrome).
Within E71.51 (disorders of peroxisome biogenesis), E71.510 is specifically for Zellweger syndrome. Related codes cover neonatal adrenoleukodystrophy (E71.511) and other disorders of peroxisome biogenesis (E71.518).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
