Valid for Submission
A25.9 is a billable diagnosis code used to specify a medical diagnosis of rat-bite fever, unspecified. The code A25.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code A25.9 might also be used to specify conditions or terms like rat bite fever.
Unspecified diagnosis codes like A25.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
Wild animals usually avoid people. They might attack, however, if they feel threatened, are sick, or are protecting their young or territory. Attacks by pets are more common. Animal bites rarely are life-threatening, but if they become infected, you can develop serious medical problems.
To prevent animal bites and complications from bites
- Never pet, handle, or feed unknown animals
- Leave snakes alone
- Watch your children closely around animals
- Vaccinate your cats, ferrets, and dogs against rabies
- Spay or neuter your dog to make it less aggressive
- Get a tetanus booster if you have not had one recently
- Wear boots and long pants when you are in areas with venomous snakes
If an animal bites you, clean the wound with soap and water as soon as possible. Get medical attention if necessary.

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 bacteria won't hurt you - less than 1% of the different types make people sick. Many are helpful. Some bacteria 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.
