What MSS Bacteremia ICD codes can I use?

If you’re looking for MSS Bacteremia ICD codes, we’d like you to know that you can use five MSS Bacteremia-related codes. Here they are:

  1. R78.81 - Bacteremia

This ICD code is meant to be used on a patient confirmed to have bacteremia. This is for bacteremia in general. No specific ICD codes mention MSS Bacteremia in their names, so it’s best to use this one since it’s for bacteremia in general.

  1. A49.01 - Methicillin susceptible Staphylococcus aureus infection, unspecified site

This ICD code is meant for a patient confirmed to have an MSSA infection, but the location isn’t specified or identified. This is best used to designate a person having a condition of this type.

  1. J15.211 - Pneumonia due to Methicillin susceptible Staphylococcus aureus

This ICD code is meant to be used on a patient confirmed to have pneumonia that emerged due to MSSA in the body.

  1. A41.01 - Sepsis due to Methicillin susceptible Staphylococcus aureus

This ICD code is meant to be used on a patient confirmed to have sepsis due to MSSA in the body. This is a life-threatening problem.

  1. B95.61 - Methicillin susceptible to Staphylococcus aureus infection as the cause of diseases classified elsewhere

This ICD code is meant to be used on a patient confirmed to have a disease caused by an MSSA infection. It’s best to use this if the MSSA-related problem that your patient has doesn’t have a specified ICD code like Items 3 and 4.

  1. Z22.321 - Carrier or suspected carrier of Methicillin susceptible Staphylococcus aureus

This ICD code is meant to be used on a patient confirmed or suspected of being a carrier of MSSA. If the patient has symptoms of MSSA bacteremia or has been detected that they do have it in their bloodstream, then you may use this code.

Are these MSSA Bacteremia ICD codes billable?

Yes. All of the aforementioned MSSA Bacteremia-related ICD codes are valid and billable.

Clinical information about MSSA Bacteremia:

Methicillin-susceptible Staphylococcus Aureus, or MSSA, is a type of bacterial infection caused by the presence of MSSA bacteria in the body. If there is MSSA in the blood, the person has MSSA Bacteremia. This is not good because having MSSA Bacteremia can lead to unwanted complications since the bacteria can reach organs like our lungs and heart. These unwanted complications can be life-threatening, like pneumonia and sepsis.

If a person has MSSA, they will likely have some issues involving their skin first, such as abscesses emerging out of nowhere, folliculitis (sores beneath hair follicles), and impetigo (blisters that can burst and leave crusts in their wake).

Once they enter the bloodstream, they might have a fever, or their body temperature will drop. They might become dazed and confused, too, as well as tired and sleepy. Having shortness of breath and pain in certain body areas are also symptoms of MSSA Bacteremia.

Synonyms include:

  • Bacteremia due to Methicillin resistant Staphylococcus aureus
  • Bacteremia due to Staphylococcus aureus
  • Staphylococcal infectious disease
  • Bronchopneumonia due to methicillin-susceptible Staphylococcus aureus
  • Pneumonia due to methicillin-susceptible Staphylococcus aureus
  • Septic shock co-occurrent with acute organ dysfunction due to methicillin-susceptible Staphylococcus aureus
  • Toxic shock syndrome due to methicillin-susceptible Staphylococcus aureus
  • Methicillin susceptible staphylococcus aureus carrier
  • Suspected carrier of methicillin-susceptible staphylococcus aureus
  • Staphylococcus carrier

Commonly asked questions

How do healthcare professionals detect the presence of MSSA bacteria in patients?

Healthcare professionals will conduct physical examinations to check if the patient has low blood pressure, a heightened heart rate if they have trouble breathing, and if they are feverish. They will also conduct blood tests/cultures to determine whether there is MSSA or other types of bacteria causing the bacteremia and other problems they might have due to bacteremia.

How do healthcare professionals treat MSSA Bacteremia?

Administering and prescribing antibiotics is the primary way of treating MSSA Bacteremia. Two to four weeks of antibiotic therapy is typically implemented.

What is the difference between MSSA and MSRA?

MSSA stands for Methicillin-susceptible Staphylococcus Aureus. MSRA stands for Methicillin-resistant Staphylococcus Aureus. The former can be treated with antibiotics, while the latter is resistant to many antibiotics. Antibiotics are still used to treat MSRA despite its resistance to many, but to determine which antibiotics can be used, healthcare professionals must first conduct blood cultures.
