E61.1 — Iron deficiency
E61.1 is a billable, specific ICD-10-CM code for iron 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.
- iron deficiency anemia (D50.-)
Other codes that can never be billed with E61.1
These codes carry an Excludes1 note pointing at E61.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E61.1 alone.
Risk adjustment
E61.1 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 E61.1 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 E61.1.
- Deficiency, deficient›iron
