About coding Osteochondrodystrophy
The ICD-10-CM code for Osteochondrodystrophy is E78.9 (Disorder of lipoprotein metabolism, unspecified).
Within E78, choose E78.9 (Disorder of lipoprotein metabolism, unspecified) only when documentation doesn't support a more specific option: pure hypercholesterolemia (E78.0), pure hyperglyceridemia (E78.1), mixed hyperlipidemia (E78.2), Hyperchylomicronemia (E78.3), other hyperlipidemia (E78.4), hyperlipidemia, unspecified (E78.5), lipoprotein deficiency (E78.6), disorders of bile acid and cholesterol metabolism (E78.7) and 1 more.
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.
