Valid for Submission

A49.02 is a billable diagnosis code used to specify a medical diagnosis of methicillin resistant staphylococcus aureus infection, unspecified site. The code A49.02 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.

The ICD-10-CM code A49.02 might also be used to specify conditions or terms like infection by methicillin resistant staphylococcus intermedius or infection by methicillin resistant staphylococcus pseudintermedius.

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.

Information for Patients


Antibiotic Resistance

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 become able to resist the effects of an antibiotic.

Using antibiotics can lead to resistance. Each time you take antibiotics, sensitive bacteria are killed. But resistant germs may be left to grow and multiply. They can spread to other people. They can also cause infections that certain antibiotics cannot cure. Methicillin-resistant Staphylococcus aureus (MRSA) is one example. It causes infections that are resistant to several common antibiotics.

MRSA

Also called: Methicillin-resistant Staphylococcus aureus

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

If a wound appears to be infected, see a health care provider. Treatments may include draining the infection and antibiotics.
