ICD-10: A56

ICD-10 code A56 pertains to "Other sexually transmitted chlamydial diseases," which encompasses a range of infections caused by the bacterium Chlamydia trachomatis. This code is part of the broader category of sexually transmitted infections (STIs) and is specifically used to classify chlamydial infections that do not fall under more specific codes for common conditions like chlamydial cervicitis or urethritis.

Clinical Description

Overview of Chlamydial Infections

Chlamydia is one of the most prevalent STIs globally, often asymptomatic, which can lead to significant complications if left untreated. The infection is primarily transmitted through sexual contact, affecting both men and women. In women, it can lead to pelvic inflammatory disease (PID), which may result in infertility or ectopic pregnancy. In men, it can cause epididymitis and, in rare cases, infertility.

Symptoms

While many individuals with chlamydial infections may not exhibit symptoms, those who do may experience:

• In Women:
• Abnormal vaginal discharge
• Burning sensation during urination
• Pain during intercourse
• Lower abdominal pain

• Bleeding between periods

• In Men:

• Discharge from the penis
• Burning sensation during urination
• Pain and swelling in one or both testicles

Complications

If untreated, chlamydial infections can lead to severe health issues, including:

• In Women:
• Pelvic inflammatory disease (PID)
• Infertility

• Ectopic pregnancy

• In Men:

• Epididymitis
• Prostatitis
• Infertility

Diagnosis

Diagnosis of chlamydial infections typically involves:

• Laboratory Tests: Nucleic acid amplification tests (NAATs) are the most sensitive and specific methods for detecting Chlamydia trachomatis.
• Clinical Evaluation: A thorough history and physical examination, including pelvic exams for women, are essential.

Treatment

Chlamydial infections are effectively treated with antibiotics. Common regimens include:

• Azithromycin: A single dose of 1 gram orally.
• Doxycycline: 100 mg orally twice a day for seven days.

It is crucial for sexual partners to be treated simultaneously to prevent reinfection.
