E64 — Sequelae of malnutrition and other nutritional deficiencies
E64 is a non-billable header ICD-10-CM code for sequelae of malnutrition and other nutritional deficiencies. It cannot be billed on its own: choose one of the more specific child codes below.
Code first
The underlying condition must be sequenced before this code.
- condition resulting from (sequela) of malnutrition and other nutritional deficiencies
Notes
Additional guidance from the ICD-10-CM tabular list.
- This category is to be used to indicate conditions in categories E43, E44, E46, E50-E63 as the cause of sequelae, which are themselves classified elsewhere. The 'sequelae' include conditions specified as such; they also include the late effects of diseases classifiable to the above categories if the disease itself is no longer present
Other codes that can never be billed with E64
These codes carry an Excludes1 note pointing at E64. 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 alone.
Risk adjustment
E64 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 history
E64 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
Code to one of these instead E64
6 child codes. Green means billable.
