A54 Gonococcal infection

Name of the Condition

• Gonococcal infection

Summary

Gonococcal infection is a sexually transmitted infection caused by Neisseria gonorrhoeae. It can affect various mucosal sites, including the genitourinary tract, rectum, pharynx, and eyes. The condition may present with or without symptoms and is characterized by localized inflammation, depending on the site of infection.

Causes

The infection is caused by Neisseria gonorrhoeae, a bacterium transmitted through sexual contact. The bacteria colonize mucosal surfaces, leading to infection. Transmission occurs via unprotected vaginal, oral, or anal sex with an infected partner.

Risk Factors

• Unprotected sexual activity with multiple partners
• History of prior gonococcal infections
• Young age (15–24 years)
• Presence of other sexually transmitted infections
• Lack of consistent condom use

Symptoms

• Dysuria (painful urination)
• Urethral or vaginal discharge
• Genital itching or irritation
• Rectal pain or discharge (with rectal infection)
• Sore throat (with pharyngeal infection)
• Eye redness or discharge (with ocular infection)

Diagnosis

Diagnosis involves clinical evaluation and laboratory testing. Nucleic acid amplification tests (NAATs) on urine, genital, rectal, or pharyngeal swabs are commonly used. Gram stain or culture may also be performed to identify the bacteria.

Treatment Options

Treatment typically involves antibiotics, such as ceftriaxone and azithromycin, to target Neisseria gonorrhoeae. The specific regimen may vary based on local resistance patterns and infection site. Sexual partners should also be tested and treated to prevent reinfection.

Prognosis and Follow-Up

With appropriate treatment, most infections resolve without complications. Follow-up testing is recommended to confirm cure, especially in cases of persistent symptoms or reinfection. Untreated infections may lead to long-term complications.

Complications

• Pelvic inflammatory disease (PID) in females
• Epididymitis or prostatitis in males
• Disseminated gonococcal infection (rare)
• Infertility or ectopic pregnancy (with PID)
• Increased HIV transmission risk

Lifestyle & Prevention

• Use condoms consistently during sexual activity
• Limit sexual partners and ensure mutual monogamy
• Get regular STI screenings, especially with new or multiple partners
• Avoid sharing personal items that may contact mucosal surfaces

When to Seek Professional Help

Seek care if you experience symptoms like painful urination, unusual discharge, or genital irritation. Also, seek evaluation after potential exposure to an infected partner, even without symptoms.

Tips for Medical Coders

When coding for gonococcal infection (A54), specify the site of infection (e.g., genitourinary, rectal, pharyngeal) using the appropriate subcategory. Document the anatomical location and any associated complications to ensure accurate code assignment.
