ICD-10 code for Hyperchloremia

The ICD-10-CM code for Hyperchloremia is E87.8 (Other disorders of electrolyte and fluid balance, not elsewhere classified).

Within E87, choose E87.8 (Other disorders of electrolyte and fluid balance, not elsewhere classified) only when documentation doesn't support a more specific option: Hyperosmolality and hypernatremia (E87.0), Hypo-osmolality and hyponatremia (E87.1), acidosis (E87.2), Alkalosis (E87.3), mixed disorder of acid-base balance (E87.4), Hyperkalemia (E87.5), Hypokalemia (E87.6) and fluid overload (E87.7).

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), DRG 641 (Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes without MCC, relative weight 0.7865), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
