About coding metabolism disorder calcium
The ICD-10-CM code for metabolism disorder calcium is E83.50 (Unspecified disorder of calcium metabolism).
Within E83.5, choose E83.50 (Unspecified disorder of calcium metabolism) only when documentation doesn't support a more specific option: hypocalcemia (E83.51), Hypercalcemia (E83.52) and other disorders of calcium metabolism (E83.59).
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.
