2025 ICD-10-CM code A74.89
Other chlamydial diseases. This code is used for chlamydial infections not otherwise specified.
Medical necessity for the services related to the chlamydial infection should be documented. This includes the signs, symptoms, and diagnostic test results that justify the diagnosis and treatment.
Diagnosis and treatment of the chlamydial infection are the clinical responsibilities. Diagnosis may involve physical examination, laboratory tests such as blood and urine tests, direct immunofluorescent technique, and enzyme-linked immunosorbent assay (ELISA). Treatment typically includes antibiotic therapy and recommendations to refrain from sexual activity.
In simple words: This code represents a chlamydia infection in a location not specifically covered by other codes.Chlamydia is a common sexually transmitted infection. Sometimes it doesn't cause symptoms, but it can lead to serious health problems if left untreated.
Other chlamydial diseases refer to infectious venereal conditions caused by the bacterium Chlamydia trachomatis, transmitted through sexual contact with an infected partner or during childbirth.The provider specifies the chlamydial diseases not represented by another code.A patient with other chlamydial diseases may be asymptomatic or experience a wide range of symptoms depending upon the organs affected. Common symptoms are fever, fatigue, abdominal pain, painful and burning urination, and weight loss. Providers diagnose the condition based on the patient’s history, physical examination, signs and symptoms, blood and urine tests, direct immunofluorescent technique, and enzyme-linked immunosorbent assay (ELISA).
Example 1: A 22-year-old female presents with lower abdominal pain.Testing reveals a chlamydial infection of the fallopian tubes, which is not coded specifically as salpingitis. A74.89 would be appropriate., A 30-year-old male experiences pain and swelling in his epididymis.Chlamydia is identified as the cause, and there are no other specific codes for chlamydial epididymitis.A74.89 is used., A newborn infant develops a chlamydial infection of the liver.As there are specific codes for neonatal chlamydial conjunctivitis and pneumonia, but not for liver involvement, A74.89 would be the correct code.
Documentation should support the diagnosis of a chlamydial infection and specify the affected site.This may include physical examination findings, laboratory results (including specific tests used for chlamydia), and details of the patient's history.
