Is E61 a billable ICD-10-CM code?

No. E61 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does E61 sit in the tabular list?

Endocrine, nutritional and metabolic diseases (E00-E89), in the block Other nutritional deficiencies (E50-E64).

What cannot be coded together with E61?

E61 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

E61

E61 — Deficiency of other nutrient elements

Non-billable headerICD-10-CM

E61 is a non-billable header ICD-10-CM code for deficiency of other nutrient elements. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

disorders of mineral metabolism (E83.-)
iodine deficiency related thyroid disorders (E00-E02)
sequelae of malnutrition and other nutritional deficiencies (E64.-)

Use additional code

Add a secondary code to capture the detail described below.

code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)

Other codes that can never be billed with E61

These codes carry an Excludes1 note pointing at E61. 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 alone.

R79.0Abnormal level of blood mineral
E83Disorders of mineral metabolism
T45.4X6Underdosing of iron and its compounds
T45.4X6AUnderdosing of iron and its compounds, initial encounter
T45.4X6DUnderdosing of iron and its compounds, subsequent encounter
T45.4X6SUnderdosing of iron and its compounds, sequela

Risk adjustment

E61 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.

Code to one of these instead E61

10 child codes. Green means billable.
