E61.8 ICD-10-CM Code: Deficiency of other specified nutrient elements

E61.8 is the ICD-10-CM diagnosis code for deficiency of other specified nutrient elements. This code describes a deficiency of a nutrient element that is not specifically listed in other deficiency codes, such as deficiencies in minerals or trace elements like selenium, chromium, or molybdenum. It is used when a patient has a documented nutritional deficiency that doesn't fit into more specific nutrient deficiency categories. E61.8 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering other nutritional deficiencies (e50-e64).

E61.8 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

Always document the specific nutrient element that is deficient in the medical record, as E61.8 is a catch-all code and specificity helps with clinical clarity and potential future audits.
