E53.0 — Riboflavin deficiency
E53.0 is a billable, specific ICD-10-CM code for riboflavin deficiency. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Ariboflavinosis
- Vitamin B2 deficiency
Excludes1 inherited from the categories above E53.0
These are not written on E53.0, but they bind it: a note on a category applies to every code beneath it. Billing E53.0 with anything listed here is a denial.
Other codes that can never be billed with E53.0
These codes carry an Excludes1 note pointing at E53.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E53.0 alone.

Risk adjustment
E53.0 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.
Medicare coverage
E53.0 is named in 2 Medicare coverage policies — 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
