E59 — Dietary selenium deficiency
E59 is a billable, specific ICD-10-CM code for dietary selenium deficiency. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- sequelae of selenium deficiency (E64.8)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Keshan disease
Risk adjustment
E59 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How E59 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to E59.
- Keshan disease
- Selenium deficiency, dietary
- Deficiency, deficient›selenium(dietary)
- Disease, diseased›Keshan
Code history
E59 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
