E64.0 — Sequelae of protein-calorie malnutrition
E64.0 is a billable, specific ICD-10-CM code for sequelae of protein-calorie malnutrition. It is valid for submission on a claim.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- retarded development following protein-calorie malnutrition (E45)
Other codes that can never be billed with E64.0
These codes carry an Excludes1 note pointing at E64.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E64.0 alone.
- E61Deficiency of other nutrient elements
Risk adjustment
E64.0 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
E64.0 is named in 12 Medicare coverage policies — 12 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How E64.0 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 E64.0.
