Hemoglobinuria

Hemoglobinuria refers to the presence of free hemoglobin in the urine, indicating intravascular hemolysis. This condition results from the breakdown of red blood cells within the bloodstream, releasing hemoglobin that is then filtered by the kidneys and excreted. It is a sign of underlying hemolytic processes rather than a disease itself.

This code is appropriate for documenting the finding of hemoglobin in the urine, typically identified through urinalysis. It applies in scenarios such as hemolytic anemia, transfusion reactions, paroxysmal nocturnal hemoglobinuria, or severe burns leading to red blood cell destruction. Documentation should clearly state the presence of hemoglobinuria.

• Always code the underlying cause of the hemoglobinuria whenever known and documented.
• Distinguish from hematuria (presence of intact red blood cells in urine); these are distinct conditions.
• Consider additional codes for associated symptoms or complications, such as anemia or acute kidney injury, if present.
