About coding iron metabolism disorder
The ICD-10-CM code for iron metabolism disorder is E83.10 (Disorder of iron metabolism, 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 E83.10.
Within E83.1, choose E83.10 (Disorder of iron metabolism, unspecified) only when documentation doesn't support a more specific option: hemochromatosis (E83.11) and other disorders of iron metabolism (E83.19).
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 642 (Inborn and Other Disorders of Metabolism, relative weight 1.3219), 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.
