ICD-10 Code E72.541 – Enteric hyperoxaluria (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E72.541 – Enteric hyperoxaluria
What it is
Enteric hyperoxaluria is excess oxalate absorption from the gut, usually due to intestinal disease or malabsorption. It can raise urinary oxalate and increase the risk of kidney stones or kidney injury.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include recurrent calcium oxalate nephrolithiasis, hyperoxaluria, or a history of malabsorptive bowel disease, bowel resection, or chronic diarrhea.
When to use this code
Use this code when the provider documents enteric hyperoxaluria or clearly links hyperoxaluria to an intestinal cause. It is appropriate when the record identifies malabsorption-related oxalate excess rather than a primary metabolic disorder. Check documentation if the cause is not specified.
Do not use for
Do not use this code for primary hyperoxaluria or for kidney stones without documented enteric hyperoxaluria. If the chart only mentions malabsorption or diarrhea without oxalate excess, this code is not supported.
Coding tip
Confirm both the oxalate disorder and the enteric cause in the note before assigning E72.541.
