Name of the Condition

• Streptococcus, Group A as the Cause of Diseases Classified Elsewhere (ICD Code B95.0)

Summary

• This condition refers to infections caused by group A Streptococcus (GAS) bacteria, which can lead to a wide range of diseases affecting various parts of the body, classified under different health conditions.

Causes

• Group A Streptococcus bacteria, naturally found in the throat and on the skin, are responsible. They are highly contagious, spreading through direct contact with respiratory droplets, mucus, or skin sores from an infected person.

Risk Factors

• Close contact with individuals with GAS infections
• Crowded environments, such as schools and military facilities
• Compromised immune systems
• Chronic illnesses such as diabetes or cancer

Symptoms

• Symptoms vary depending on the disease and can include fever, sore throat, skin rashes, and swelling.
• Conditions like strep throat, scarlet fever, or rheumatic fever can arise from these infections.

Diagnosis

• Throat culture or rapid antigen detection tests (RADTs) for strep throat
• Blood tests and skin swabs to identify presence of GAS in other infections

Treatment Options

• Antibiotics, primarily penicillin or amoxicillin, to eliminate the bacteria
• Supportive care for symptomatic relief, such as pain relievers and fever reducers

Prognosis and Follow-Up

• Most GAS infections respond well to antibiotic treatment with timely diagnosis.
• Regular follow-ups might be necessary for severe cases, such as those leading to rheumatic fever or kidney complications.

Complications

• Untreated infections can lead to serious conditions like rheumatic fever, post-streptococcal glomerulonephritis, or invasive GAS diseases.

  Lifestyle & Prevention

• Practicing good hygiene, such as frequent handwashing
• Avoiding close contact with infected individuals
• Timely treatment of strep infections to prevent complications

When to Seek Professional Help

• High fever, difficulty swallowing, or rash
• Symptoms of severe GAS infections, including fast breathing or difficulty breathing, chest pain, or signs of sepsis (e.g., confusion, extreme weakness)

Tips for Medical Coders

• Ensure to check the primary condition caused by GAS and code separately for it.
• Avoid using B95.0 as a primary diagnosis code; it should be listed as a secondary code to indicate the infeсtive agent.
