About coding Cardiopathy mucopolysaccharidosis
The ICD-10-CM code for Cardiopathy mucopolysaccharidosis is E76.3 (Mucopolysaccharidosis, unspecified).
Within E76, choose E76.3 (Mucopolysaccharidosis, unspecified) only when documentation doesn't support a more specific option: Mucopolysaccharidosis, type I (E76.0), Mucopolysaccharidosis, type II (E76.1), other mucopolysaccharidoses (E76.2), other disorders of glucosaminoglycan metabolism (E76.8) and glucosaminoglycan metabolism disorder, unspecified (E76.9).
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.
