E83 — Disorders of mineral metabolism

Non-billable headerICD-10-CM

E83 is a non-billable header ICD-10-CM code for disorders of mineral metabolism. 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.

dietary mineral deficiency (E58-E61)
parathyroid disorders (E20-E21)
vitamin D deficiency (E55.-)

Other codes that can never be billed with E83

These codes carry an Excludes1 note pointing at E83. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E83 alone.

M83Adult osteomalacia
N20Calculus of kidney and ureter
P78.84Gestational alloimmune liver disease
Q82Other congenital malformations of skin
Q84.1Congenital morphological disturbances of hair, not elsewhere classified
R79.0Abnormal level of blood mineral
E55.0Rickets, active
E58Dietary calcium deficiency

Risk adjustment

E83 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 E83

8 child codes. Green means billable.
