ICD-10 Code E72.19 – Other disorders of sulfur-bearing amino-acid metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E72.19 – Other disorders of sulfur-bearing amino-acid metabolism
What it is
E72.19 identifies a disorder affecting the metabolism of sulfur-bearing amino acids, such as methionine or cysteine. Use it when the record documents a specific inherited or acquired metabolic problem that does not fit a more defined code.
Clinical signs
Clinical features vary; refer to documentation. Patients may have abnormal amino-acid handling, developmental concerns, neurologic findings, or other metabolic abnormalities noted by the clinician.
When to use this code
Use this code when the provider documents an unspecified or other disorder of sulfur-bearing amino-acid metabolism. It is appropriate when the condition is confirmed, but the chart does not name a more specific aminoacidopathy. Do not infer the diagnosis from screening alone unless the provider confirms it.
Do not use for
Do not use E72.19 for general malnutrition, isolated abnormal lab results, or conditions with a more specific metabolic diagnosis. Check documentation if the record names a distinct amino-acid disorder.
Coding tip
Assign E72.19 only when the provider clearly documents this exact metabolic disorder and no more specific code applies.
