A77.49 is a billable ICD-10 code used to specify a medical diagnosis of other ehrlichiosis. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Human anaplasmosis due to Anaplasma phagocytophilum
- Human ehrlichiosis
- Infection by Ehrlichia ewingii
- Ehrlichiosis-. a tick-borne disease characterized by fever; headache; myalgias; anorexia; and occasionally rash. it is caused by several bacterial species and can produce disease in dogs; cattle; sheep; goats; horses; and humans. the primary species causing human disease are ehrlichia chaffeensis; anaplasma phagocytophilum; and ehrlichia ewingii.
- Anaplasmosis-. a disease usually in cattle caused by parasitization of the red blood cells by bacteria of the genus anaplasma.
- Anaplasma-. a genus of gram-negative bacteria whose organisms are obligate parasites of vertebrates. species are transmitted by arthropod vectors with the host range limited to ruminants. anaplasma marginale is the most pathogenic species and is the causative agent of severe bovine anaplasmosis.
- Anaplasmosis-. an infection that is caused by anaplasma phagocytophilum, which is transmitted to humans by infected ticks; it is characterized by fever, headache, chills, and myalgia.

Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods, or spirals. They are so small that a line of 1,000 could fit across a pencil eraser. Most types of don't make you sick. Many types are helpful. Some of them help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese.
But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli.
Antibiotics are the usual treatment. When you take antibiotics, follow the directions carefully. Each time you take antibiotics, you increase the chances that bacteria in your body will learn to resist them causing antibiotic resistance. Later, you could get or spread an infection that those antibiotics cannot cure.

If you spend time outdoors or have pets that go outdoors, you need to beware of ticks. Ticks are small bloodsucking parasites. Many species transmit diseases to animals and people. Some of the diseases you can get from a tick bite are Lyme disease, ehrlichiosis, Rocky Mountain spotted fever and tularemia.
Some ticks are so small that they can be difficult to see. Ticks may get on you if you walk through areas where they live, such as tall grass, leaf litter or shrubs.
Tick-borne diseases occur worldwide, including in your own backyard. To help protect yourself and your family, you should:
- Use a chemical repellent with DEET, permethrin or picaridin
- Wear light-colored protective clothing
- Tuck pant legs into socks
- Avoid tick-infested areas
- Check yourself, your children and your pets daily for ticks and carefully remove any ticks you find
