A49.02 is a billable ICD-10 code used to specify a medical diagnosis of methicillin resistant staphylococcus aureus infection, unspecified site. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like A49.02 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Infection by methicillin resistant Staphylococcus intermedius
- Infection by methicillin resistant Staphylococcus pseudintermedius

The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Antibiotics are medicines that fight bacterial infections. Used properly, they can save lives. But there is a growing problem of antibiotic resistance. It happens when bacteria change and resist the effects of an antibiotic. Resistant bacteria may continue to grow and multiply.
Each time you take antibiotics there is a risk that the bacteria will become resistant. Resistant infections can be difficult and sometimes impossible to treat. They can spread to other people. Methicillin-resistant Staphylococcus aureus (MRSA) is one example. It causes infections that are resistant to several common antibiotics.
Antibiotic resistance can cause problems. To help prevent antibiotic resistance:
- Don't use antibiotics for viruses like colds or flu. Antibiotics don't work on viruses.
- Don't ask your health care provider to give you an antibiotic.
- When you take antibiotics, follow the directions carefully. Finish your medicine even if you feel better. If you stop treatment too soon, some bacteria may survive and re-infect you.
- Do not share your antibiotics with others.
- Don't save antibiotics for later or use someone else's prescription.

MRSA stands for methicillin-resistant Staphylococcus aureus. It causes a staph infection (pronounced "staff infection") that is resistant to several common antibiotics. There are two types of infection. Hospital-associated MRSA happens to people in health care settings. Community-associated MRSA happens to people who have close skin-to-skin contact with others, such as athletes involved in football and wrestling.
Infection control is key to stopping MRSA in hospitals. To prevent community-associated MRSA:
- Practice good hygiene
- Keep cuts and scrapes clean and covered with a bandage until healed
- Avoid contact with other people's wounds or bandages
- Avoid sharing personal items, such as towels, washcloths, razors, or clothes
- Wash soiled sheets, towels, and clothes in hot water with bleach and dry in a hot dryer
If a wound appears to be infected, see a health care provider. Treatments may include draining the infection and antibiotics.
