Sequelae of malnutrition and other nutritional deficiencies (E64)

ICD-10 code section E64 covers the long-term effects, or sequelae, of malnutrition and various nutritional deficiencies. These codes are specifically used to identify health conditions that arise as consequences of earlier inadequate nutrition or vitamin deficiencies.

This section includes codes such as E64.0 for sequelae of protein-calorie malnutrition (also called sequelae of protein-energy malnutrition or cachectic alopecia), and codes like E64.1 and E64.2 for the sequelae of vitamin A and vitamin C deficiencies, respectively. For example, E64.3 denotes the late effects of rickets, a bone disorder caused by vitamin D deficiency. Additionally, E64.8 is used for sequelae resulting from other less common nutritional deficiencies, while E64.9 covers sequelae of unspecified nutritional deficiencies, including conditions like nutritional ataxic neuropathy and nutritional alopecia. Medical coders searching for the ICD-10 code for sequelae of nutritional disorders will find that these codes help precisely document the lasting impacts of past malnutrition or vitamin-related issues, supporting accurate patient records and care planning.

Instructional Notations

Code First

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
