About E78.6
E78.6 is the ICD-10-CM diagnosis code for lipoprotein deficiency. It belongs to category E78 (disorders of lipoprotein metabolism and other lipidemias), block E70-E88 (metabolic disorders) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within E78 (disorders of lipoprotein metabolism and other lipidemias), E78.6 is specifically for lipoprotein deficiency. Related codes cover pure hypercholesterolemia (E78.0), pure hyperglyceridemia (E78.1), mixed hyperlipidemia (E78.2), Hyperchylomicronemia (E78.3), other hyperlipidemia (E78.4), hyperlipidemia, unspecified (E78.5), disorders of bile acid and cholesterol metabolism (E78.7), other disorders of lipoprotein metabolism (E78.8) 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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 272.5 (lipoprotein deficiencies).
