M00.00 is a billable ICD-10 code used to specify a medical diagnosis of staphylococcal arthritis, unspecified joint. 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 M00.00 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:
- Infective polyarthritis caused by bacteria
- Staphylococcal arthritis
- Staphylococcal arthritis and polyarthritis

Most kinds of arthritis cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Infectious arthritis is an infection in the joint. The infection comes from a bacterial, viral, or fungal infection that spreads from another part of the body. Symptoms of infectious arthritis include:
- Intense pain in the joint
- Joint redness and swelling
- Chills and fever
- Inability to move the area with the infected joint
One type of infectious arthritis is reactive arthritis. The reaction is to an infection somewhere else in your body. The joint is usually the knee, ankle, or toe. Sometimes, reactive arthritis is set off by an infection in the bladder, or in the urethra, which carries urine out of the body. In women, an infection in the vagina can cause the reaction. For both men and women, it can start with bacteria passed on during sex. Another form of reactive arthritis starts with eating food or handling something that has bacteria on it.
To diagnose infectious arthritis, your health care provider may do tests of your blood, urine, and joint fluid. Treatment includes medicines and sometimes surgery.

What are Staphylococcal (staph) infections?
Staphylococcus (staph) is a group of bacteria. There are more than 30 types. A type called Staphylococcus aureus causes most infections.
Staph bacteria can cause many different types of infections, including:
- Skin infections, which are the most common types of staph infections
- Bacteremia, an infection of the bloodstream. This can lead to sepsis, a very serious immune response to infection.
- Bone infections
- Endocarditis, an infection of the inner lining of the heart chambers and valves
- Food poisoning
- Toxic shock syndrome (TSS), a life-threatening condition caused by toxins from certain types of bacteria
What causes staph infections?
Some people carry staph bacteria on their skin or in their noses, but they do not get an infection. But if they get a cut or wound, the bacteria can enter the body and cause an infection.
Staph bacteria can spread from person to person. They can also spread on objects, such as towels, clothing, door handles, athletic equipment, and remotes. If you have staph and do not handle food properly when you are preparing it, you can also spread staph to others.
Who is at risk for staph infections?
Anyone can develop a staph infection, but certain people are at greater risk, including those who:
- Have a chronic condition such as diabetes, cancer, vascular disease, eczema, and lung disease
- Have a weakened immune system, such as from HIV/AIDS, medicines to prevent organ rejection, or chemotherapy
- Had surgery
- Use a catheter, breathing tube, or feeding tube
- Are on dialysis
- Inject illegal drugs
- Do contact sports, since you may have skin-to-skin contact with others or share equipment
What are the symptoms of staph infections?
The symptoms of a staph infection depend on the type of infection:
- Skin infections can look like pimples or boils. They may be red, swollen, and painful. Sometimes there is pus or other drainage. They can turn into impetigo, which turns into a crust on the skin, or cellulitis, a swollen, red area of skin that feels hot.
- Bone infections can cause pain, swelling, warmth, and redness in the infected area. You may also have chills and a fever.
- Endocarditis causes some flu-like symptoms: fever, chills, and fatigue. It also causes symptoms such as rapid heartbeat, shortness of breath, and fluid buildup in your arms or legs.
- Food poisoning typically causes nausea and vomiting, diarrhea, and a fever. If you lose too many fluids, you may also become dehydrated.
- Pneumonia symptoms include a high fever, chills, and cough that doesn't get better. You may also have chest pain and shortness of breath.
- Toxic shock syndrome (TSS) causes high fever, sudden low blood pressure, vomiting, diarrhea, and confusion. You may have a sunburn-like rash somewhere on your body. TSS can lead to organ failure.
How are staph infections diagnosed?
Your health care provider will do a physical exam and ask about your symptoms. Often, providers can tell if you have a staph skin infection by looking at it. To check for other types of staph infections, providers may do a culture, with a skin scraping, tissue sample, stool sample, or throat or nasal swabs. There may be other tests, such as imaging tests, depending on the type of infection.
What are the treatments for staph infections?
Treatment for staph infections is antibiotics. Depending on the type of infection, you may get a cream, ointment, medicines (to swallow), or intravenous (IV). If you have an infected wound, your provider might drain it. Sometimes you may need surgery for bone infections.
Some staph infections, such as MRSA (methicillin-resistant Staphylococcus aureus), are resistant to many antibiotics. There are still certain antibiotics that can treat these infections.
Can staph infections be prevented?
Certain steps can help to prevent staph infections:
- Use good hygiene, including washing your hands often
- Don't share towels, sheets, or clothing with someone who has a staph infection
- It's best not to share athletic equipment. If you do need to share, make sure that it properly cleaned and dried before you use it.
- Practice food safety, including not preparing food for others when you have a staph infection
- If you have a cut or wound, keep it covered
