Name of the Condition

Chlamydial Infection of Pharynx (ICD Code: A56.4)

Summary

Chlamydial infection of the pharynx is a bacterial infection caused by Chlamydia trachomatis, affecting the throat. It is often associated with oral sexual contact with an infected partner.

Causes

The primary cause of chlamydial infection of the pharynx is the transmission of the Chlamydia trachomatis bacterium through oral-genital sexual contact with an infected person.

Risk Factors

• Engaging in unprotected oral sex
• Having multiple sexual partners
• Previous history of sexually transmitted infections (STIs)
• Sexual contact with a partner diagnosed with chlamydia

Symptoms

• Often asymptomatic
• Sore throat
• Redness in the throat
• Swollen lymph nodes in the neck
• Mild fever

Diagnosis

• Throat swab test for nucleic acid amplification tests (NAATs)
• Comprehensive clinical examination
• STI screening to rule out other infections

Treatment Options

• Antibiotic therapy, typically with azithromycin or doxycycline
• Treatment of sexual partners to prevent reinfection
• Use of medications helps clear the infection and prevent complications

Prognosis and Follow-Up

• Generally good if treated promptly with antibiotics
• Follow-up tests may be recommended to ensure the infection has cleared
• Regular sexual health check-ups are advised

Complications

• If untreated, can lead to the spread of infection to other parts of the body
• Potential for recurring infections
• Higher risk of spreading the infection to sexual partners

Lifestyle & Prevention

• Practicing safe sex, including the use of dental dams
• Regular STI testing for sexually active individuals
• Open communication with sexual partners about STI status

When to Seek Professional Help

• Symptoms of a sore throat persisting after possible exposure to an STI
• Notification of exposure by a sexual partner

Tips for Medical Coders

• Ensure accurate documentation of the condition's pharyngeal involvement to distinguish from other forms of chlamydial infections.
• Verify that the oral cavity is the confirmed site of the infection for correct coding as A56.4.
• Avoid confusion with other pharyngeal infections by identifying the specific bacterial cause.
