ICD-10 Code E72 – Other disorders of amino-acid metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E72 – Other disorders of amino-acid metabolism
What it is
E72 covers inherited or acquired disorders that affect how the body processes amino acids. Use it when the record identifies an amino-acid metabolism disorder but does not specify a more exact code.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include developmental delay, poor growth, neurologic symptoms, or abnormal metabolic screening results consistent with an amino-acid processing disorder.
When to use this code
Use E72 when the provider documents an unspecified other disorder of amino-acid metabolism, or when the diagnosis is confirmed but not named more precisely. It may also fit follow-up care for a known amino-acid disorder when the exact subtype is not documented. Check documentation if the chart names a specific condition.
Do not use for
Do not use this code for a clearly identified amino-acid disorder with its own specific ICD-10-CM code. Avoid it when the record only suggests a screening abnormality or a nonspecific metabolic concern.
Coding tip
Code the most specific documented amino-acid disorder first; use E72 only when the provider leaves the condition unspecified.
