A20.3 - Plague meningitis

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Plague
• Plague meningitis

Clinical Information

• African Horse Sickness-. an insect-borne reovirus infection of horses, mules and donkeys in africa and the middle east; characterized by pulmonary edema, cardiac involvement, and edema of the head and neck.
• Feline Panleukopenia-. a highly contagious dna virus infection of the cat family, characterized by fever, enteritis and bone marrow changes. it is also called feline ataxia, feline agranulocytosis, feline infectious enteritis, cat fever, cat plague, and show fever. it is caused by feline panleukopenia virus or the closely related mink enteritis virus or canine parvovirus.
• Influenza A virus-. the type species of the genus influenzavirus a that causes influenza and other diseases in humans and animals. antigenic variation occurs frequently between strains, allowing classification into subtypes and variants. transmission is usually by aerosol (human and most non-aquatic hosts) or waterborne (ducks). infected birds shed the virus in their saliva, nasal secretions, and feces.
• Influenza in Birds-. infection of domestic and wild fowl and other birds with influenza a virus. avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic poultry.
• Plague-. an acute infectious disease caused by yersinia pestis that affects humans, wild rodents, and their ectoparasites. this condition persists due to its firm entrenchment in sylvatic rodent-flea ecosystems throughout the world. bubonic plague is the most common form.
• Plague Vaccine-. a suspension of killed yersinia pestis used for immunizing people in enzootic plague areas.
• Rinderpest-. a viral disease of cloven-hoofed animals caused by morbillivirus. it may be acute, subacute, or chronic with the major lesions characterized by inflammation and ulceration of the entire digestive tract. the disease was declared successfully eradicated worldwide in 2010.
• Yersinia pestis-. the etiologic agent of plague in man, rats, ground squirrels, and other rodents.
• Morbillivirus-. a genus of the family paramyxoviridae (subfamily paramyxovirinae) where the virions of most members have hemagglutinin but not neuraminidase activity. all members produce both cytoplasmic and intranuclear inclusion bodies. measles virus is the type species.
• Plague-. a gram-negative bacterial infection caused by yersinia pestis. it is usually transmitted to humans from bites of infected rodent fleas. it is manifested as a bubonic, septicemic, or pneumonic plague. in bubonic plague, the lymph nodes adjacent to the site of the skin bite are infected and enlarged. in septicemic plague, the infection spreads directly through the bloodstream. in pneumonic plague, the infection spreads to the lungs either following bubonic plague, or by inhalation of infective droplets. if untreated, it may lead to death.

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

Meningitis

Meningitis is inflammation of the thin tissue that surrounds the brain and spinal cord, called the meninges. There are several types of meningitis. The most common is viral meningitis. You get it when a virus enters the body through the nose or mouth and travels to the brain. Bacterial meningitis is rare, but can be deadly. It usually starts with bacteria that cause a cold-like infection. It can cause stroke, hearing loss, and brain damage. It can also harm other organs. Pneumococcal infections and meningococcal infections are the most common causes of bacterial meningitis.

Anyone can get meningitis, but it is more common in people with weak immune systems. Meningitis can get serious very quickly. You should get medical care right away if you have:

• A sudden high fever
• A severe headache
• A stiff neck
• Nausea or vomiting

Early treatment can help prevent serious problems, including death. Tests to diagnose meningitis include blood tests, imaging tests, and a spinal tap to test cerebrospinal fluid. Antibiotics can treat bacterial meningitis. Antiviral medicines may help some types of viral meningitis. Other medicines can help treat symptoms.

There are vaccines to prevent some of the bacterial infections that cause meningitis.

Plague

Plague is an infection caused by the bacterium Yersinia pestis. The bacteria are found mainly in rats and in the fleas that feed on them. People and other animals can get plague from rat or flea bites. In the past, plague destroyed entire civilizations. Today plague is uncommon, due to better living conditions and antibiotics.

There are three forms of plague:

• Bubonic plague causes the tonsils, adenoids, spleen, and thymus to become inflamed. Symptoms include fever, aches, chills, and tender lymph glands.
• In septicemic plague, bacteria multiply in the blood. It causes fever, chills, shock, and bleeding under the skin or other organs.
• Pneumonic plague is the most serious form. Bacteria enter the lungs and cause pneumonia. People with the infection can spread this form to others. This type could be a bioterror agent.

Lab tests can diagnose plague. Treatment is a strong antibiotic. There is no vaccine.
