ICD-10 code for nutritional disturbance

The ICD-10-CM code for nutritional disturbance is E63.9 (Nutritional deficiency, 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 E63.9.

Within E63, choose E63.9 (Nutritional deficiency, unspecified) only when documentation doesn't support a more specific option: essential fatty acid [EFA] deficiency (E63.0), Imbalance of constituents of food intake (E63.1) and other specified nutritional deficiencies (E63.8).

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.
