ICD-10 Code E72.00 – Disorders of amino-acid transport, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E72.00 – Disorders of amino-acid transport, unspecified
What it is
E72.00 identifies an unspecified disorder affecting amino-acid transport. Use it when the record confirms an amino-acid transport problem but does not name a specific inherited condition or subtype.
Clinical signs
Clinical features vary; refer to documentation. Reported findings in amino-acid transport disorders may include abnormal amino-acid handling, metabolic abnormalities, or related inherited disease patterns, but you should not assume specifics without provider documentation.
When to use this code
Use this code when the clinician documents a disorder of amino-acid transport and does not specify the exact transport defect. It is also appropriate when the chart notes a suspected or confirmed transport disorder, but the subtype is not available in the record. Check documentation if the diagnosis is later clarified.
Do not use for
Do not use this code for a clearly identified amino-acid disorder with a more specific ICD-10-CM code. Do not assign it when the record only mentions abnormal labs or a family history without a documented transport disorder.
Coding tip
Code the most specific transport disorder documented; if the provider only states “unspecified,” E72.00 is appropriate.
