Myoglobinuria
ICD-10 R82.1 is a billable code used to indicate a diagnosis of myoglobinuria.
Myoglobinuria is a condition characterized by the presence of myoglobin in the urine, which can occur due to muscle injury or breakdown. Myoglobin is a protein found in muscle tissue that carries oxygen. When muscle cells are damaged, myoglobin is released into the bloodstream and subsequently filtered by the kidneys into the urine. Clinically, myoglobinuria may present with dark, tea-colored urine, muscle pain, weakness, and swelling. It is often associated with conditions such as rhabdomyolysis, which can result from trauma, extreme physical exertion, or certain medications. Laboratory findings typically include elevated serum creatine kinase (CK) levels, and urinalysis may show positive results for blood without red blood cells, indicating myoglobin presence. Prompt recognition and management are crucial to prevent complications such as acute kidney injury, which can arise from the nephrotoxic effects of myoglobin.
Detailed history of muscle symptoms, laboratory findings, and treatment plans.
Patients presenting with muscle pain and dark urine after strenuous exercise.
Ensure comprehensive documentation of all contributing factors to muscle injury.
Acute assessment of symptoms, rapid laboratory testing results, and immediate management plans.
Patients with acute muscle trauma or exertional rhabdomyolysis presenting to the ER.
Document the urgency of the situation and any interventions performed.
Used to assess kidney function and electrolyte levels in patients with myoglobinuria.
Document the rationale for ordering the panel and any abnormal findings.
Internal medicine and emergency medicine may require different levels of detail in documentation.
Common causes include rhabdomyolysis due to trauma, extreme physical exertion, certain medications, and metabolic disorders.
Myoglobinuria typically presents with dark urine but without red blood cells on urinalysis, while hematuria shows red blood cells in the urine.
