About coding Tocopherol deficiency
The ICD-10-CM code for Tocopherol deficiency is E56.0 (Deficiency of vitamin E).
Within E56 (other vitamin deficiencies), E56.0 is specifically for deficiency of vitamin E. Related codes cover deficiency of vitamin K (E56.1), deficiency of other vitamins (E56.8) and vitamin deficiency, unspecified (E56.9).
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 640 (Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes with MCC, relative weight 1.3395) and DRG 641 (Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes without MCC, relative weight 0.7865), 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.
