E64 is a non-billable ICD-10-CM category code for sequelae of malnutrition and other nutritional deficiencies, so it cannot be submitted on claims. Use a more specific code from this category instead, such as E64.0, E64.1, E64.2, and E64.3.

Specific Coding for Sequelae of malnutrition and other nutritional deficienciesOverview

Non-specific codes like E64 require more characters. Use one of these billable codes instead:

  • Use E64.1 for Sequelae of vitamin A deficiency

  • Use E64.2 for Sequelae of vitamin C deficiency

  • Use E64.3 for Sequelae of rickets

  • Use E64.8 for Sequelae of other nutritional deficiencies

  • Use E64.9 for Sequelae of unspecified nutritional deficiency

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to E64: its own notes plus those printed at block E50-E64 and Chapter 4. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • transitory endocrine and metabolic disorders specific to newborn (P70-P74)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Block E50-E64 Other nutritional deficiencies applies to 50 codes

Code First

The underlying condition named in the note is sequenced before this code.

  • condition resulting from (sequela) of malnutrition and other nutritional deficiencies

Notes

General instructions on how these codes are used.

On E64 itself
  • 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
From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.

Malnutrition

Malnutrition means that your body isn't getting enough calories or the right balance of nutrients to stay healthy. This can happen if you don't get enough protein, carbohydrates, and fats, eat too much unhealthy food, or don't get the vitamins and minerals your body needs.

Questions About E64Overview

What is the ICD-10 code for sequelae of malnutrition and other nutritional deficiencies?

E64 is the ICD-10-CM category for sequelae of malnutrition and other nutritional deficiencies, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is E64 (Sequelae of malnutrition and other nutritional deficiencies) a billable code?

No. This is a category header that groups the codes for sequelae of malnutrition and other nutritional deficiencies, and headers cannot be submitted on claims. Claims for sequelae of malnutrition and other nutritional deficiencies need a more specific code from this category, such as E64.0, E64.1, and E64.2.

What is coded first with E64?

The Code First note reads: condition resulting from (sequela) of malnutrition and other nutritional deficiencies. When one of these applies, it is sequenced before E64.
