About coding Fructosemia
The ICD-10-CM code for Fructosemia is E74.12 (Hereditary fructose intolerance).
Within E74.1 (disorders of fructose metabolism), E74.12 is specifically for hereditary fructose intolerance. Related codes cover disorder of fructose metabolism, unspecified (E74.10), essential fructosuria (E74.11) and other disorders of fructose metabolism (E74.19).
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.
