About coding SCAD deficiency
The ICD-10-CM code for SCAD deficiency is E71.312 (Short chain acyl CoA dehydrogenase deficiency).
Within E71.31 (disorders of fatty-acid oxidation), E71.312 is specifically for short chain acyl CoA dehydrogenase deficiency. Related codes cover long chain/very long chain acyl CoA dehydrogenase deficiency (E71.310), Medium chain acyl CoA dehydrogenase deficiency (E71.311), Glutaric aciduria type II (E71.313), muscle carnitine palmitoyltransferase deficiency (E71.314) and other disorders of fatty-acid oxidation (E71.318).
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.
