Clinical Information

• Altitude Sickness

  multiple symptoms associated with reduced oxygen at high altitude.

• Aryl Hydrocarbon Receptor Nuclear Translocator

  aryl hydrocarbon receptor nuclear translocator is a basic helix-loop-helix motif containing protein that forms a complex with dioxin receptor. the complex binds xenobiotic regulatory elements and activates transcription of a variety of genes including udp glucuronosyltransferase. ahr nuclear translocator is also a subunit of hypoxia-inducible factor 1.

• Cell Hypoxia

  a condition of decreased oxygen content at the cellular level.

• Fetal Hypoxia

  deficient oxygenation of fetal blood.

• Hypoxia

  sub-optimal oxygen levels in the ambient air of living organisms.

• Hypoxia, Brain

  a reduction in brain oxygen supply due to anoxemia (a reduced amount of oxygen being carried in the blood by hemoglobin), or to a restriction of the blood supply to the brain, or both. severe hypoxia is referred to as anoxia and is a relatively common cause of injury to the central nervous system. prolonged brain anoxia may lead to brain death or a persistent vegetative state. histologically, this condition is characterized by neuronal loss which is most prominent in the hippocampus; globus pallidus; cerebellum; and inferior olives.

• Hypoxia-Inducible Factor 1

  a basic helix-loop-helix transcription factor that plays a role in apoptosis. it is composed of two subunits: aryl hydrocarbon receptor nuclear translocator and hypoxia-inducible factor 1, alpha subunit.

• Hypoxia-Inducible Factor 1, alpha Subunit

  hypoxia-inducible factor 1, alpha subunit is a basic helix-loop-helix transcription factor that is regulated by oxygen availability and is targeted for degradation by vhl tumor suppressor protein.

• Hypoxia-Inducible Factor-Proline Dioxygenases

  dioxygenase enzymes that specifically hydroxylate a proline residue on the hypoxia-inducible factor 1, alpha subunit. they are oxygen-dependent enzymes that play an important role in mediating cellular adaptive responses to hypoxia.

• Hypoxia-Ischemia, Brain

  a disorder characterized by a reduction of oxygen in the blood combined with reduced blood flow (ischemia) to the brain from a localized obstruction of a cerebral artery or from systemic hypoperfusion. prolonged hypoxia-ischemia is associated with ischemic attack, transient; brain infarction; brain edema; coma; and other conditions.

• Tumor Hypoxia

  hypoxic conditions in tumor cells due to the tumor outgrowing its blood supply. it is associated with increased metastasis and resistance to radiotherapy and drug therapy.

• Altitude

  a vertical distance measured from a known level on the surface of a planet or other celestial body.

• Fetal Blood

  blood of the fetus. exchange of nutrients and waste between the fetal and maternal blood occurs via the placenta. the cord blood is blood contained in the umbilical vessels (umbilical cord) at the time of delivery.

• Oxygen

  an element with atomic symbol o, atomic number 8, and atomic weight [15.99903; 15.99977]. it is the most abundant element on earth and essential for respiration.

R09.02 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Patient Education

Lung Diseases

When you breathe, your lungs take in oxygen from the air and deliver it to the bloodstream. The cells in your body need oxygen to work and grow. During a normal day, you breathe nearly 25,000 times. People with lung disease have difficulty breathing. Millions of people in the U.S. have lung disease. If all types of lung disease are lumped together, it is the number three killer in the United States.

The term lung disease refers to many disorders affecting the lungs, such as asthma, COPD, infections like influenza, pneumonia and tuberculosis, lung cancer, and many other breathing problems. Some lung diseases can lead to respiratory failure.
