Bronchopneumonia - Inflammation of the lung parenchyma that is associated with BRONCHITIS, usually involving lobular areas from TERMINAL BRONCHIOLES to the PULMONARY ALVEOLI. The affected areas become filled with exudate that forms consolidated patches.
Chlamydial Pneumonia - Pneumonia caused by infections with the genus CHLAMYDIA; and CHLAMYDOPHILA, usually with CHLAMYDOPHILA PNEUMONIAE.
Cryptogenic Organizing Pneumonia - An interstitial lung disease of unknown etiology, occurring between 21-80 years of age. It is characterized by a dramatic onset of a "pneumonia-like" illness with cough, fever, malaise, fatigue, and weight loss. Pathological features include prominent interstitial inflammation without collagen fibrosis, diffuse fibroblastic foci, and no microscopic honeycomb change. There is excessive proliferation of granulation tissue within small airways and alveolar ducts.
Eosinophils - Granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin.
Hamman-Rich Syndrome - Acute idiopathic interstitial pneumonitis characterized by diffuse PULMONARY ALVEOLI damage with uniform edematous connective tissue proliferation. It is often associated with extensive fibroblastic distortion of the lung parenchyma and leads to ADULT RESPIRATORY DISTRESS SYNDROME in later stages.
Healthcare-Associated Pneumonia - Infection of the lung often accompanied by inflammation that is acquired through an interaction within a healthcare institution often through a therapeutic experience (e.g., use of catheters or ventilators).
Idiopathic Interstitial Pneumonias - A group of interstitial lung diseases with no known etiology. There are several entities with varying patterns of inflammation and fibrosis. They are classified by their distinct clinical-radiological-pathological features and prognosis. They include IDIOPATHIC PULMONARY FIBROSIS; CRYPTOGENIC ORGANIZING PNEUMONIA; and others.
Lung Diseases, Interstitial - A diverse group of lung diseases that affect the lung parenchyma. They are characterized by an initial inflammation of PULMONARY ALVEOLI that extends to the interstitium and beyond leading to diffuse PULMONARY FIBROSIS. Interstitial lung diseases are classified by their etiology (known or unknown causes), and radiological-pathological features.
Murine pneumonia virus - A species of the genus PNEUMOVIRUS causing pneumonia in mice.
Organizing Pneumonia - Any obstructive lung disease characterized by consolidated formation of GRANULATION TISSUE polyps within ALVEOLAR DUCTS AND ALVEOLI. It is classified as either primary (cryptogenic organizing pneumonia) or secondary organizing pneumonia. Secondary organizing pneumonia after transplantation is called bronchiolitis obliterans syndrome.
Pneumonia - Infection of the lung often accompanied by inflammation.
Pneumonia of Calves, Enzootic - Chronic endemic respiratory disease of dairy calves and an important component of bovine respiratory disease complex. It primarily affects calves up to six months of age and the etiology is multifactorial. Stress plus a primary viral infection is followed by a secondary bacterial infection. The latter is most commonly associated with PASTEURELLA MULTOCIDA producing a purulent BRONCHOPNEUMONIA. Sometimes present are MANNHEIMIA HAEMOLYTICA; HAEMOPHILUS SOMNUS and mycoplasma species.
Pneumonia of Swine, Mycoplasmal - A chronic, clinically mild, infectious pneumonia of PIGS caused by MYCOPLASMA HYOPNEUMONIAE. Ninety percent of swine herds worldwide are infected with this economically costly disease that primarily affects animals aged two to six months old. The disease can be associated with porcine respiratory disease complex. PASTEURELLA MULTOCIDA is often found as a secondary infection.
Pneumonia, Aspiration - A type of lung inflammation resulting from the aspiration of food, liquid, or gastric contents into the upper RESPIRATORY TRACT.
Pneumonia, Atypical Interstitial, of Cattle - A cattle disease of uncertain cause, probably an allergic reaction.
Pneumonia, Bacterial - Inflammation of the lung parenchyma that is caused by bacterial infections.
Pneumonia, Lipid - Pneumonia due to aspiration or inhalation of various oily or fatty substances or otherwise accumulation of endogenous lipid substances in the PULMONARY ALVEOLI.
Pneumonia, Mycoplasma - Interstitial pneumonia caused by extensive infection of the lungs (LUNG) and BRONCHI, particularly the lower lobes of the lungs, by MYCOPLASMA PNEUMONIAE in humans. In SHEEP, it is caused by MYCOPLASMA OVIPNEUMONIAE. In CATTLE, it may be caused by MYCOPLASMA DISPAR.
Pneumonia, Necrotizing - Severe complication of pneumonia characterized by liquefaction of lung tissue.
Pneumonia, Pneumococcal - A febrile disease caused by STREPTOCOCCUS PNEUMONIAE.
Pneumonia, Pneumocystis - A pulmonary disease in humans occurring in immunodeficient or malnourished patients or infants, characterized by DYSPNEA, tachypnea, and HYPOXEMIA. Pneumocystis pneumonia is a frequently seen opportunistic infection in AIDS. It is caused by the fungus PNEUMOCYSTIS JIROVECII. The disease is also found in other MAMMALS where it is caused by related species of Pneumocystis.
Pneumonia, Progressive Interstitial, of Sheep - Chronic respiratory disease caused by the VISNA-MAEDI VIRUS. It was formerly believed to be identical with jaagsiekte (PULMONARY ADENOMATOSIS, OVINE) but is now recognized as a separate entity.
Pneumonia, Rickettsial - Pneumonia caused by infection with bacteria of the family RICKETTSIACEAE.
Pneumonia, Staphylococcal - Pneumonia caused by infections with bacteria of the genus STAPHYLOCOCCUS, usually with STAPHYLOCOCCUS AUREUS.
Pneumonia, Ventilator-Associated - Serious INFLAMMATION of the LUNG in patients who required the use of PULMONARY VENTILATOR. It is usually caused by bacterial CROSS INFECTION in hospitals.
Pneumonia, Viral - Inflammation of the lung parenchyma that is caused by a viral infection.
Pneumovirus - A genus of the family PARAMYXOVIRIDAE (subfamily PNEUMOVIRINAE) where the human and bovine virions have neither hemagglutinin nor neuraminidase activity. RESPIRATORY SYNCYTIAL VIRUS, HUMAN is the type species.
Pulmonary Alveoli - Small polyhedral outpouchings along the walls of the alveolar sacs, alveolar ducts and terminal bronchioles through the walls of which gas exchange between alveolar air and pulmonary capillary blood takes place.
Pulmonary Eosinophilia - A condition characterized by infiltration of the lung with EOSINOPHILS due to inflammation or other disease processes. Major eosinophilic lung diseases are the eosinophilic pneumonias caused by infections, allergens, or toxic agents.
Radiation Pneumonitis - Inflammation of the lung due to harmful effects of ionizing or non-ionizing radiation.
Rickettsiaceae - A family of gram-negative bacteria belonging to the order Rickettsiales.
Streptococcus pneumoniae - A gram-positive organism found in the upper respiratory tract, inflammatory exudates, and various body fluids of normal and/or diseased humans and, rarely, domestic animals.
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
