Encounter for screening for other viral diseases

This code signifies a patient encounter for the purpose of screening for viral diseases other than HIV, hepatitis, or human papillomavirus (HPV). It is used when a patient presents without symptoms, and the primary reason for the visit is to detect the presence of a viral infection through a screening test.

Apply this code for routine screenings for various viral infections, such as cytomegalovirus (CMV) in pregnant patients, Epstein-Barr virus (EBV) in specific populations, or other viral pathogens when no signs or symptoms of active infection are present. This code is appropriate when the screening is performed as part of a general health check-up or due to risk factors, rather than diagnostic work-up.

• Do not use this code for screening for HIV (Z11.4x), hepatitis (Z11.51), or HPV (Z11.52).
• If a specific viral disease is being screened for and has its own dedicated screening code, use that more specific code instead.
• This code is for asymptomatic screening; if the patient has symptoms and a viral infection is suspected, a diagnostic code should be used.
