Myoglobinuria

This code represents the presence of myoglobin in the urine, indicating muscle damage or breakdown. Myoglobinuria is a sign of rhabdomyolysis, a condition where damaged muscle fibers release their contents into the bloodstream.

Use this code when laboratory findings confirm the presence of myoglobin in a patient's urine. Documentation should clearly state myoglobinuria, often in the context of acute kidney injury, trauma, or drug-induced muscle damage.

• Always code the underlying cause of the rhabdomyolysis and myoglobinuria first.
• Do not confuse with hemoglobinuria, which indicates red blood cell breakdown.
• Ensure documentation specifies myoglobin, not just "pigmenturia" or "dark urine."
