A20 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of plague. The code is not specific and is NOT valid for the year 2023 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
- 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.
Specific Coding for Plague
Non-specific codes like A20 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for plague:
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:

- infection due to Yersinia pestis
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.
