Unspecified sexually transmitted disease, unspecified site
ICD-10 A64 is a billable code used to indicate a diagnosis of unspecified sexually transmitted disease, unspecified site.
A64 is used to classify unspecified sexually transmitted diseases (STDs) when the specific type of infection is not identified. This code encompasses a range of infections that can affect the genital and urogenital areas, including but not limited to bacterial, viral, and parasitic infections. Common STDs include chlamydia, gonorrhea, syphilis, herpes, and human immunodeficiency virus (HIV). Symptoms may vary widely, from asymptomatic cases to severe manifestations such as genital lesions, discharge, and systemic symptoms. The lack of specificity in this code necessitates careful clinical evaluation and testing to determine the exact nature of the infection. Screening protocols typically involve a thorough patient history, physical examination, and laboratory tests, including nucleic acid amplification tests (NAATs) for bacterial STDs and serological tests for viral infections. Accurate coding is crucial for appropriate treatment and public health reporting, as STDs can have significant implications for reproductive health and transmission risk.
Detailed patient history, laboratory results, and treatment plans.
Patients presenting with symptoms of STDs, such as genital lesions or discharge.
Ensure all relevant tests are documented to support the use of A64.
Comprehensive evaluation of urogenital symptoms, including urinalysis and imaging if necessary.
Men presenting with dysuria or pelvic pain potentially related to STDs.
Document any differential diagnoses to justify the use of A64.
Used when testing for STDs in patients with symptoms.
Document the reason for testing and any relevant patient history.
Infectious disease specialists should ensure comprehensive testing is performed.
Use A64 when a patient presents with symptoms of a sexually transmitted disease, but the specific infection has not been identified through testing.
