Chlamydial lymphogranuloma (venereum)

This code represents lymphogranuloma venereum (LGV), a chronic sexually transmitted infection caused by specific serovars of Chlamydia trachomatis. It typically presents with transient genital lesions followed by regional lymphadenopathy, which can progress to buboes, fistulas, and strictures.

Use this code when documentation confirms a diagnosis of chlamydial lymphogranuloma venereum. This includes cases with characteristic genital ulcers, inguinal lymphadenopathy, or proctitis caused by LGV. Documentation should specify the diagnosis of LGV, often confirmed by laboratory testing for Chlamydia trachomatis serovars L1, L2, or L3.

• Do not confuse with other chlamydial infections (e.g., A74.9 for unspecified chlamydial infection).
• Ensure documentation specifies "lymphogranuloma venereum" to support this specific code.
• Consider additional codes for any associated complications, such as strictures or fistulas, if documented.
