ICD-10-CM Code For Sequelae Of Malnutrition And Other Nutritional Deficiencies: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group E64 includes sequelae and residual conditions related to malnutrition and other nutritional deficiencies, such as protein-calorie malnutrition consequences and unspecified nutritional deficiency sequelae. These ICD-10-CM diagnosis codes are used to document persistent effects of nutritional disorders, capturing disease severity, chronicity, and functional impact. Accurate coding within the ICD-10-CM E64 group supports complete clinical documentation and appropriate reimbursement.

ICD-10-CM E64: Sequelae Of Malnutrition And Other Nutritional Deficiencies Overview

This group represents conditions resulting from malnutrition and other nutritional deficiencies, including long-term consequences and residual effects. These diagnoses affect nutritional status and can impact multiple organ systems and functional ability. Accurate coding matters because it documents complexity, influences care planning, and supports appropriate reimbursement.

ICD-10-CM E64: Sequelae Of Malnutrition And Other Nutritional Deficiencies Overview

When to Use

Use a code from this group when a patient presents with ongoing or residual clinical problems attributable to a past nutritional deficiency rather than an active unmanaged deficiency. Codes in this group should be selected when documentation specifies sequelae or late effects of malnutrition or other nutritional deficiencies.

DRG Code	Description

793	Full Term Neonate with Major Problems

Typical Clinical Scenarios

An elderly homebound patient with progressive weight loss and generalized weakness presents for primary care follow-up after a bout of influenza that left them eating poorly for several weeks. The clinician documents persistent muscle wasting, low body mass index, and reduced functional status attributable to prolonged inadequate intake rather than an acute malabsorption disorder; a sequela of prior malnutrition is recorded to reflect ongoing nutritional impairment. Typical codes: E64.0, E64.9
A middle-aged person with a history of bariatric surgery several years earlier is evaluated in clinic for chronic iron-deficiency anemia and skin/hair changes despite supplementation; the team attributes these findings to long-term nutritional deficiencies resulting from altered gastrointestinal anatomy and reports a late complication of nutrient malabsorption. Typical codes: E64.2, E64.3
A pediatric patient with cerebral palsy and feeding difficulties is admitted from home with failure to thrive and developmental regression after an intercurrent viral illness; because the child has persistent growth faltering and signs of micronutrient deficiencies despite prior interventions, a code for other specified nutritional deficiency sequela is assigned to capture the chronic, treatment-resistant nutritional state contributing to hospital care. Typical codes: E64.1, E64.8
