ICD-10 Code D59.30 – Hemolytic-uremic syndrome, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D59.30 – Hemolytic-uremic syndrome, unspecified
What it is
D59.30 identifies hemolytic-uremic syndrome when the record does not specify a cause or subtype. It refers to a condition involving hemolysis, low platelets, and kidney injury, but you should code only what is documented.
Clinical signs
Typical documentation may note anemia from hemolysis, thrombocytopenia, and acute renal impairment. Clinical features vary; refer to documentation for the exact syndrome type and any associated trigger.
When to use this code
Use D59.30 when the provider documents hemolytic-uremic syndrome and does not name a more specific form. It is appropriate for unspecified HUS in discharge summaries, problem lists, or consult notes. If the cause or subtype is stated, code that more specific diagnosis instead.
Do not use for
Do not use this code for hemolytic-uremic syndrome with a documented specific cause or variant. Do not assign it when the record only mentions anemia, thrombocytopenia, or acute kidney injury without HUS. Check documentation.
Coding tip
Confirm that the provider actually documents HUS, because related findings alone do not justify D59.30.
