Valid for Submission
E72.02 is a billable diagnosis code used to specify a medical diagnosis of hartnup's disease. The code E72.02 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code E72.02 might also be used to specify conditions or terms like hartnup disorder, renal type, hartnup disorder, renal/jejunal type or neutral 1 amino acid transport defect.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code E72.02 are found in the index:
- - Disease, diseased - See Also: Syndrome;
- - H (Hartnup's) - E72.02
- - Hartnup (pellagra-cerebellar ataxia-renal aminoaciduria) - E72.02
- - Hart's (pellagra-cerebellar ataxia-renal aminoaciduria) - E72.02
- - H (Hartnup's) disease - E72.02
- - Hartnup's disease - E72.02
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Hartnup disorder, renal type
- Hartnup disorder, renal/jejunal type
- Neutral 1 amino acid transport defect
Convert E72.02 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code E72.02 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Amino Acid Metabolism Disorders
Metabolism is the process your body uses to make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Your digestive system breaks the food parts down into sugars and acids, your body's fuel. Your body can use this fuel right away, or it can store the energy in your body. If you have a metabolic disorder, something goes wrong with this process.
One group of these disorders is amino acid metabolism disorders. They include phenylketonuria (PKU) and maple syrup urine disease. Amino acids are "building blocks" that join together to form proteins. If you have one of these disorders, your body may have trouble breaking down certain amino acids. Or there may be a problem getting the amino acids into your cells. These problems cause a buildup of harmful substances in your body. That can lead to serious, sometimes life-threatening, health problems.
These disorders are usually inherited. A baby who is born with one may not have any symptoms right away. Because the disorders can be so serious, early diagnosis and treatment are critical. Newborn babies get screened for many of them, using blood tests.
Treatments may include special diets, medicines, and supplements. Some babies may also need additional treatments if there are complications.

Hartnup disease is a condition caused by the body's inability to absorb certain protein building blocks (amino acids) from the diet. As a result, affected individuals are not able to use these amino acids to produce other substances, such as vitamins and proteins. Most people with Hartnup disease are able to get the vitamins and other substances they need with a well-balanced diet.
People with Hartnup disease have high levels of various amino acids in their urine (aminoaciduria). For most affected individuals, this is the only sign of the condition. However, some people with Hartnup disease have episodes during which they exhibit other signs, which can include skin rashes; difficulty coordinating movements (cerebellar ataxia); and psychiatric symptoms, such as depression or psychosis. These episodes are typically temporary and are often triggered by illness, stress, nutrient-poor diet, or fever. These features tend to go away once the trigger is remedied, although the aminoaciduria remains. In affected individuals, signs and symptoms most commonly occur in childhood.
