Conditions such as high altitude and hypoxic lung diseases may lead to secondary polycythemia. We examined the relationship between high-altitude polycythemia and protein-uria and hyperuricemia in Cerro de Pasco, Peru (altitude, 4,300 m). Any elevation of hemoglobin or hematocrit above normal values for age and sex is considered erythrocytosis. It differentiates between primary and secondary polycythemia. Causes of secondary polycythemia or physiological polycythemia may be caused by: High Altitude (altitude sickness). Carbon monoxide and high altitude exposure are other causes of hypoxia. However, the normal range of hematocrit progressively increases with altitude, and appropriate adjustment needs to be made. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Genetics play a major role in both primary and secondary polycythemia. Secondary polycythemia is caused by natural or artificial factors. It can occur due to rare underlying conditions or certain situations, such as high altitudes.

An aid in distinguishing between primary and secondary polycythemia . Chronic exposure to high altitude is associated with the development of erythrocytosis, proteinuria, and, in some cases, hyperuricemia. Secondary polycythemia in which the production of erythropoietin increases appropriately is called physiologic polycythemia. Nabili, Siamak N. “What Is Polycythemia Vera? References: 1. Short description: Secondary polycythemia. On Mount Everest, siEp was significantly (P less than 0.01) elevated above … 1965 aug;66:304-14. secondary polycythemia in adolescents at high altitude. pmid: 14322076 High-altitude polycythemia (HAPC) is a chronic high-altitude disease that can lead to an increase in the production of red blood cells in the people who live in the plateau, a hypoxia environment, for a long time. … This is a hormone produced by the kidneys that stimulates the bone marrow cells to produce red blood cells. High EPO Levels; High EPO levels indicate secondary polycythemia. Therefore, the main difference between primary and secondary polycythemia is the causes and effects of each type of absolute polycythemia. 2% B. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes). Secondary polycythaemia is where an underlying condition causes more erythropoietin to be produced. 2016 2017 2018 2019 2020 2021 Billable/Specific Code. should be avoided to prevent secondary polycythemia. Secondary polycythemia can be caused by a variety of erythropoietin-producing renal lesions and cancers. cyanotic heart and hypoxic lung … On descent, with removal of altitude hypoxia, siEp decreased, but despite secondary polycythemia levels remained measurable and in the range found in subjects normally resident at sea level. Smoking B. Renal artery stenosis C. Polycystic kidney D. Polycythemia vera E. High altitude. Hypoxic disease.e.g. A very important part of diagnosing secondary polycythemia is differentiating it from primary polycythemia (also called polycythemia rubra vera or Vaquez' disease). The contents of this site are for informational purposes only and are meant to be discussed with your physician or other qualified health care professional before being acted on. Secondary polycythemia. Living in high altitude and some disease conditions cause secondary polycythemia. Differentiating between appropriate secondary polycythemia (eg, high-altitude living, pulmonary disease, tobacco use) and inappropriate secondary polycythemia (eg, tumors) Identifying candidates for erythropoietin (EPO) replacement therapy (eg, those with chronic renal failure) Subsequent evaluation should be aimed at determining the cause. Therefore, it is known as physiologic polycythemia. Polycythemia vera may be discovered through a blood count done for another reason, even before people have any symptoms. treger a, shaw db, grover rf. ICD-9-CM 289.0 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 289.0 should only be used for claims with a date of service on or before September 30, 2015. The incidence of neonatal polycythemia is 0.4–4.0% of all births and is higher at high altitudes than at sea level. ICD-10-CM Code for Secondary polycythemia D75.1 ICD-10 code D75.1 for Secondary polycythemia is a medical classification as listed by WHO under the range - Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism . 10% C. 30% D. 50% E. 70%. Secondary polycythemia is also called secondary erythrocytosis. In secondary erythrocytosis, only red blood cells (RBCs) are increased, whereas in polycythemia vera, RBCs, white blood cells (WBCs), and platelets will usually be increased. Polycythemia is a condition in which the body produces too many red blood cells. Unlike secondary polycythemia, primary polycythemia cannot be traced to an underlying condition such as smoking, high altitude, or chronic lung disease. The number of red blood cells, the level of the protein that carries oxygen in red blood cells (hemoglobin) and the percentage of red blood cells in the total blood volume (the hematocrit) are abnormally high. Cigarette smoking should be ruled out because it is the most common cause of secondary polycythemia. Those who develop the problem due to genetic mutations have “primary polycythemia”, while those who get it due to some of the other causes listed below has “secondary polycythemia.” Stanford Children’s Health. 2- All of the following are causes of secondary absolute polycythemia, except: A. Secondary polycythemia would more accurately be called secondary erythrocytosis or erythrocythemia, as those terms specifically denote increased red blood cells. Secondary causes of increased red blood cell mass (e.g., heavy smoking, chronic pulmonary disease, renal disease) are more common than polycythemia vera and must be excluded. Conditions which may result in a physiologically appropriate polycythemia include: Altitude related – This physiologic polycythemia is a normal adaptation to living at high altitudes (see altitude sickness). Secondary polycythemia and factor V Leiden mutations were the most commonly associated conditions. Secondary polycythemia, similar to primary polycythemia vera, is a disorder that causes an overproduction of red blood cells. Background: Polycythemia is a condition wherein there is an increased hemoglobin or hematocrit measured on complete blood count (CBC) tests.The increased levels may be relative or absolute.. Smoking, high altitudes, mountain climbing, etc. Secondary polycythaemia. Hypoxia is the major stimulus for EPO production. When too many red blood cells are produced, the blood becomes thick, hindering its passage through the smaller blood vessels. 3- The risk acute myeloid leukemia in polycythemia vera is A. 1. j lab clin med. 1. Genetic Mutation: Polycythemia Vera Condition and disease information is written and/or reviewed by the MediResource Clinical Team. In-vitro culture of the erythroid cells can also be done to diagnose secondary polycythemia. Phlebotomy is indicated in patients with severe symptoms and with a high risk of thrombosis. Secondary polycythemia resolves when the underlying cause is treated. An elevated EPO level points to a diagnosis of secondary polycythemia, but a normal level does not rule out secondary polycythemia as the elevations in EPO can be intermittent. Health conditions that can cause secondary polycythaemia … Symptoms, Life Expectancy, Treatment & Causes.” This should include, but not be limited to, the following: Measurement of arterial oxygen saturation levels using a pulse-oximeter: low levels would likely indicate a pulmonary or cardiac cause. Treatment of High Altitude Polycythemia by Acetazolamide The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. High-altitude illness susceptibility varies among individuals . The red blood cells in some patients with secondary polycythemia may carry an abnormal form of hemoglobin that does not release oxygen readily (high-affinity hemoglobin). 6.
