Z86.14 Personal history of Methicillin resistant Staphylococcus aureus infection

Name of the Condition

• Personal history of Methicillin resistant Staphylococcus aureus infection (ICD-10 code: Z86.14)

Summary

"Personal history of Methicillin resistant Staphylococcus aureus (MRSA) infection" refers to individuals who have previously been diagnosed with and treated for MRSA. This code does not indicate current active infection but serves as a record of past events that may influence future healthcare decisions, such as infection risk or treatment choices.

Causes

This code documents past infections caused by MRSA, a type of bacteria resistant to many antibiotics. The specific causes depend on the original MRSA infection experienced by the patient, which may have originated from skin, wound, or other sources.

Risk Factors

• Previous MRSA infection increases the risk of future MRSA colonization or infection.
• Weakened immune systems, which may increase susceptibility to initial infections.
• Frequent exposure to healthcare settings or close contact with infected individuals.

Symptoms

Symptoms are associated with the original MRSA infection and are not applicable to the historical status itself. The code reflects past events, not current symptoms.

Diagnosis

This code is assigned based on the patient's medical history and documented evidence of previous MRSA treatment. No current diagnostic testing is required unless reactivation is suspected.

Treatment Options

No treatment is needed for the historical status. However, management of potential complications or prevention of future infections may be considered based on individual risk.

Prognosis and Follow-Up

The prognosis varies; many recover fully, while some may experience lingering effects or increased susceptibility to future infections. Regular follow-up is advisable if symptoms persist or if there is a risk of reactivation.

Complications

• Increased risk for future MRSA infections.
• Potential for skin, wound, or systemic complications if reinfected.

Lifestyle & Prevention

• Practice good hygiene, including handwashing and wound care.
• Avoid sharing personal items like towels or razors.
• Follow healthcare provider recommendations for preventing future infections.

When to Seek Professional Help

Seek medical attention if new symptoms of infection develop, such as fever, redness, swelling, or pus, which may indicate a new MRSA infection.

Tips for Medical Coders

Document the code Z86.14 when a patient has a confirmed history of MRSA infection, with clear medical record evidence of prior diagnosis and treatment. Ensure the code is used for historical status only, not active infection.
