Methemoglobinemia, unspecified
ICD-10 D74.9 is a billable code used to indicate a diagnosis of methemoglobinemia, unspecified.
Methemoglobinemia is a condition characterized by an elevated level of methemoglobin in the blood, which is a form of hemoglobin that is unable to effectively release oxygen to body tissues. This condition can be caused by various factors, including exposure to certain drugs, chemicals, or congenital defects. Patients may present with symptoms such as cyanosis, fatigue, shortness of breath, and in severe cases, neurological impairment. The diagnosis is typically confirmed through a blood test measuring methemoglobin levels. Treatment may involve the administration of methylene blue, oxygen therapy, or blood transfusions in severe cases. The unspecified nature of this code indicates that the specific cause of methemoglobinemia has not been determined, which may complicate treatment and management strategies. Understanding the underlying causes is crucial for effective intervention and prevention of further complications.
Detailed lab results, patient history, and treatment plans.
Patients presenting with cyanosis and unexplained hypoxia.
Ensure clear documentation of methemoglobin levels and any treatments administered.
Immediate assessment findings, treatment provided, and follow-up care.
Acute presentations of cyanosis and respiratory distress.
Document the timeline of symptoms and interventions to support coding.
Used to evaluate blood components, including methemoglobin levels.
Document the reason for the CBC and any abnormal findings.
Hematologists may require additional tests based on CBC results.
Common causes include exposure to certain medications (like benzocaine), chemicals (such as aniline dyes), and congenital enzyme deficiencies.
