Clinical Information
  • Methemoglobinemia inherited in an autosomal recessive pattern. It is caused by deficiency of the enzyme nadh methemoglobin reductase or the presence of abnormal hemoglobin m. It presents with cyanosis early in life. There is no evidence of cardiopulmonary disease present.
ICD-10-CM D74.0 is grouped within Diagnostic Related Group(s) (MS-DRG v37.0):
  • 811 Red blood cell disorders with mcc
