Secondary polycythemia
ICD-10 D75.1 is a billable code used to indicate a diagnosis of secondary polycythemia.
Secondary polycythemia is a condition characterized by an increase in red blood cell mass due to external factors rather than intrinsic bone marrow pathology. This condition often arises in response to chronic hypoxia, which can be caused by various factors such as chronic obstructive pulmonary disease (COPD), sleep apnea, or living at high altitudes. It can also occur due to increased erythropoietin production from tumors or other conditions that stimulate red blood cell production. Clinically, patients may present with symptoms related to increased blood viscosity, such as headaches, dizziness, and hypertension. Diagnosis typically involves a complete blood count (CBC) showing elevated hemoglobin and hematocrit levels, alongside a thorough evaluation of underlying causes. Management focuses on treating the underlying condition, and in some cases, therapeutic phlebotomy may be indicated to reduce red blood cell mass and alleviate symptoms.
Detailed history of symptoms, laboratory results, and underlying conditions.
Patients with chronic lung disease presenting with elevated hemoglobin levels.
Ensure clear documentation of the cause of secondary polycythemia to avoid misclassification.
Assessment of respiratory function and oxygen saturation levels.
Patients with COPD or sleep apnea showing signs of secondary polycythemia.
Documenting the relationship between respiratory conditions and polycythemia is crucial.
Used to evaluate hemoglobin levels in suspected cases of polycythemia.
Document the indication for the CBC and any relevant clinical findings.
Hematologists may require additional tests to confirm diagnosis.
Primary polycythemia is a myeloproliferative disorder, while secondary polycythemia is a response to external factors such as hypoxia or increased erythropoietin production.
