ICD-10 Code E72.0 – Disorders of amino-acid transport (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E72.0 – Disorders of amino-acid transport
What it is
E72.0 identifies inherited disorders that impair transport of amino acids in the body. These conditions can prevent normal movement of specific amino acids across cell membranes or renal tubules.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include aminoaciduria, growth problems, developmental delay, or neurologic symptoms depending on the specific transport defect.
When to use this code
Use E72.0 when the provider documents a disorder of amino-acid transport, including a named transport defect or a nonspecific inherited transport disorder. Code it from the diagnosis statement, genetics note, or metabolic workup when the chart supports impaired amino-acid transport.
Do not assign it for isolated abnormal urine amino acids without a documented transport disorder. If the record names a specific inherited condition, confirm whether a more specific ICD-10-CM code applies.
Do not use for
Do not use E72.0 for acquired malnutrition, general protein deficiency, or routine abnormal laboratory results. Check documentation if the provider has not clearly identified a transport disorder.
Coding tip
Look for wording such as “amino-acid transport defect” or “transport disorder” and code the most specific documented diagnosis.
