About E83.2

E83.2 is the ICD-10-CM diagnosis code for disorders of zinc metabolism. It belongs to category E83 (disorders of mineral metabolism), block E70-E88 (metabolic disorders) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E83 (disorders of mineral metabolism), E83.2 is specifically for disorders of zinc metabolism. Related codes cover disorders of copper metabolism (E83.0), disorders of iron metabolism (E83.1), disorders of phosphorus metabolism and phosphatases (E83.3), disorders of magnesium metabolism (E83.4), disorders of calcium metabolism (E83.5), other disorders of mineral metabolism (E83.8) and disorder of mineral metabolism, unspecified (E83.9).

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 602 (Cellulitis with MCC, relative weight 1.4273) and DRG 603 (Cellulitis without MCC, relative weight 0.8635), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 686.8 (other specified local infections of skin and subcutaneous tissue).
