Varicella (chickenpox)
ICD-10 B01 is a billable code used to indicate a diagnosis of varicella (chickenpox).
Varicella, commonly known as chickenpox, is an infectious disease caused by the varicella-zoster virus (VZV), a member of the herpesvirus family. It is characterized by an itchy, blister-like rash, fatigue, fever, and headache. The disease is highly contagious and spreads through respiratory droplets or direct contact with the rash. The incubation period typically ranges from 10 to 21 days, with most individuals developing symptoms around 14 days after exposure. Vaccination against varicella is a key preventive measure, with the varicella vaccine recommended for children, adolescents, and adults who have not had the disease. Complications can arise, particularly in immunocompromised individuals, pregnant women, and newborns, including bacterial infections of the skin, pneumonia, and encephalitis. The disease is generally mild in healthy children but can lead to severe outcomes in vulnerable populations. Accurate coding for varicella is essential for proper treatment and management of the disease, as well as for tracking vaccination efforts and public health initiatives.
Documentation of vaccination history, clinical presentation, and any complications.
Routine check-ups for vaccinated children, management of varicella in unvaccinated children.
Consideration of the patient's age and vaccination status is critical for accurate coding.
Detailed clinical notes on the patient's history, symptoms, and laboratory results.
Management of varicella in immunocompromised patients or those with severe complications.
Documentation must reflect the severity of the disease and any complications for accurate coding.
Administering the varicella vaccine to a child during a routine visit.
Documentation of vaccine administration and patient consent.
Pediatricians should ensure accurate recording of vaccination history.
Varicella is the primary infection caused by the varicella-zoster virus, resulting in chickenpox, while herpes zoster (shingles) is a reactivation of the virus later in life, often causing a painful rash.
