About coding cholesterol elevated
The ICD-10-CM code for cholesterol elevated is E78.00 (Pure hypercholesterolemia, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on E78.00.
Within E78.0, choose E78.00 (unspecified) only when documentation doesn't support a more specific option: familial hypercholesterolemia (E78.01).
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.
