Code Classification

  • Endocrine, nutritional and metabolic diseases
    (E00–E89)
    • Malnutrition
      (E40-E46)
      • Unspecified protein-calorie malnutrition
        (E46)

E46 is a billable diagnosis code used to specify a medical diagnosis of unspecified protein-calorie malnutrition. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like E46 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Hypoalbuminemia

    a condition in which albumin level in blood (serum albumin) is below the normal range. hypoalbuminemia may be due to decreased hepatic albumin synthesis, increased albumin catabolism, altered albumin distribution, or albumin loss through the urine (albuminuria).

  • Child Nutrition Disorders

    disorders caused by nutritional imbalance, either overnutrition or undernutrition, occurring in children ages 2 to 12 years.

  • Fetal Nutrition Disorders

    disorders caused by nutritional imbalance, either overnutrition or undernutrition, in the fetus in utero.

  • Infant Nutrition Disorders

    disorders caused by nutritional imbalance, either overnutrition or undernutrition, occurring in infants ages 1 month to 24 months.

  • Malnutrition

    an imbalanced nutritional status resulting from insufficient intake of nutrients to meet normal physiological requirement.

  • Protein-Energy Malnutrition

    the lack of sufficient energy or protein to meet the body's metabolic demands, as a result of either an inadequate dietary intake of protein, intake of poor quality dietary protein, increased demands due to disease, or increased nutrient losses.

  • Severe Acute Malnutrition

    acute form of malnutrition which usually affects children, characterized by a very low weight for height (below -3z scores of the median world health organization standards), visible severe wasting, or occurrence of nutritional edema. it can be a direct or indirect cause of fatality in children suffering from diarrhea and pneumonia. do not confuse with starvation, a condition in which the body is not getting enough food, usually for extended periods of time.

  • Diabetic Ketoacidosis

    a life-threatening complication of diabetes mellitus, primarily of type 1 diabetes mellitus with severe insulin deficiency and extreme hyperglycemia. it is characterized by ketosis; dehydration; and depressed consciousness leading to coma.

  • Hypoproteinemia

    a condition in which total serum protein level is below the normal range. hypoproteinemia can be caused by protein malabsorption in the gastrointestinal tract, edema, or proteinuria.

  • Protein-Losing Enteropathies

    pathological conditions in the intestines that are characterized by the gastrointestinal loss of serum proteins, including serum albumin; immunoglobulins; and at times lymphocytes. severe condition can result in hypogammaglobulinemia or lymphopenia. protein-losing enteropathies are associated with a number of diseases including intestinal lymphangiectasis; whipple's disease; and neoplasms of the small intestine.

  • Fetus

    the unborn young of a viviparous mammal, in the postembryonic period, after the major structures have been outlined. in humans, the unborn young from the end of the eighth week after conception until birth, as distinguished from the earlier embryo, mammalian.

  • APTX wt Allele|AOA|AOA1|AXA1|Aprataxin wt Allele|Ataxia 1, Early Onset With Hypoalbuminemia Gene|EAOH|EOAHA|FHA-HIT

    human aptx wild-type allele is located in the vicinity of 9p21.1 and is approximately 139 kb in length. this allele, which encodes aprataxin protein, is involved in dna repair. mutation of the gene is associated with ataxia-ocular apraxia type 1.

  • Ataxia-Oculomotor Apraxia Type 1|AOA1|Ataxia, Early-Onset, with Oculomotor Apraxia and Hypoalbuminemia|EAOH

    an autosomal recessive cerebellar ataxia caused by mutation(s) in the aptx gene, encoding aprataxin. it is characterized by peripheral axonal neuropathy, oculomotor apraxia, and hypoalbuminemia.

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Malnutrition NOS
  • Protein-calorie imbalance NOS

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • nutritional deficiency NOS E63.9

Patient Education


Malnutrition

Food provides the energy and nutrients you need to be healthy. If you don't get enough nutrients -- including proteins, carbohydrates, fats, vitamins, and minerals - you may suffer from malnutrition.

Causes of malnutrition include:

  • Lack of specific nutrients in your diet. Even the lack of one vitamin can lead to malnutrition.
  • An unbalanced diet
  • Certain medical problems, such as malabsorption syndromes and cancers

Symptoms may include fatigue, dizziness, and weight loss. Or, you may have no symptoms. To diagnose the cause of the problem, your doctor may do blood tests and a nutritional assessment. Treatment may include replacing the missing nutrients and treating the underlying cause.
