Lymphogranuloma venereum

This code represents lymphogranuloma venereum (LGV), a chronic, ulcerative, and granulomatous sexually transmitted infection caused by specific serovars of Chlamydia trachomatis. It primarily affects the lymphatic tissue, leading to characteristic inguinal or femoral lymphadenopathy and potential anogenital syndromes.

Use this code for confirmed cases of LGV, typically diagnosed through serological testing, nucleic acid amplification tests (NAATs), or culture from affected lesions or lymph nodes. It is appropriate for both acute and chronic manifestations of the disease, including proctitis, urethritis, or the classic "groove sign" in the groin.

• Ensure documentation clearly specifies LGV and not other chlamydial infections, which are coded differently.
• Consider sequencing this code as the primary diagnosis when LGV is the reason for the encounter.
• Look for documentation of specific LGV serovars (L1, L2, L3) if available, although not required for this code.
