2025 ICD-10-CM code A51.4
Other secondary syphilis. This condition is the second stage of syphilis, a sexually transmitted infection (STI).
Medical necessity for services related to A51.4 is established by the diagnosis of other secondary syphilis.Testing to confirm the diagnosis and treatment to prevent disease progression are considered medically necessary.
Providers diagnose other secondary syphilis based on patient history, physical examination, blood tests (serological tests for syphilis), and potentially body fluid tests. Treatment typically involves intramuscular injections of penicillin, or alternative antibiotics for patients with penicillin allergies. Patient education focuses on avoiding sexual contact until the infection is resolved and emphasizing the importance of early detection and treatment to prevent disease progression.
- Certain infectious and parasitic diseases (A00-B99)
- Infections with a predominantly sexual mode of transmission (A50-A64)
In simple words: Other secondary syphilis is the second stage of syphilis, a sexually transmitted disease.It can cause a range of symptoms like fever, sore throat, tiredness, muscle aches, swollen glands, and skin rashes. If not treated, it can lead to more serious health problems.
Other secondary syphilis is the second stage of syphilis, a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. This stage is characterized by a variety of symptoms that affect different organ systems, and may include fever, sore throat, malaise, fatigue, muscle aches, and enlarged lymph nodes. Skin rashes and lesions are also common.If left untreated, the infection can progress to latent or tertiary stages, which can have serious consequences.
Example 1: A 25-year-old patient presents with a widespread, non-itchy rash, fever, and swollen lymph nodes. Blood tests confirm a diagnosis of secondary syphilis., A 30-year-old patient with a history of untreated primary syphilis now exhibits malaise, hair loss, and mucous membrane lesions, consistent with other secondary syphilis., A patient presents with symptoms suggestive of secondary syphilis, including joint pain and muscle aches. Darkfield microscopy and serologic tests confirm the diagnosis.
Documentation for A51.4 should include the type and location of lesions (if present), the stage of syphilis (secondary), and any associated symptoms.Lab results confirming the diagnosis are essential. Details of treatment provided and patient education should also be documented.
