About coding fructose 1
The ICD-10-CM code for fructose 1 is E74.19 (Other disorders of fructose metabolism).
Within E74.1, choose E74.19 (Other disorders of fructose metabolism) only when documentation doesn't support a more specific option: disorder of fructose metabolism, unspecified (E74.10), essential fructosuria (E74.11) and hereditary fructose intolerance (E74.12).
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 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
