ICD-10 Code E72.09 – Other disorders of amino-acid transport (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E72.09 – Other disorders of amino-acid transport
What it is
E72.09 identifies other inherited or acquired problems affecting amino-acid transport. Use it when documentation specifies an amino-acid transport disorder but does not name a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Patients may have findings consistent with abnormal amino-acid handling, but the chart should identify the transport disorder rather than only nonspecific metabolic symptoms.
When to use this code
Use E72.09 when the provider documents an amino-acid transport disorder and no more specific ICD-10-CM code applies. It may also fit when the record states “other” or “unspecified” amino-acid transport abnormality. Verify the diagnosis is active and clinically relevant.
Do not use for
Do not use this code for amino-acid metabolism disorders, nutritional protein problems, or isolated abnormal lab findings without a diagnosed transport disorder. Check documentation if the condition is better described by another metabolic code.
Coding tip
Code only what the provider documents; if the record names a specific amino-acid transport defect, choose that more precise code instead of E72.09.
