ICD-10-CM B01.9 is grouped within Diagnostic Related Group(s) (MS-DRG v36.0):
- A contagious childhood disorder caused by the varicella zoster virus. It is transmitted via respiratory secretions and contact with chickenpox blister contents. It presents with a vesicular skin rush, usually associated with fever, headache, and myalgias. The pruritic fluid-filled vesicles occur 10-21 days after exposure and last for 3-4 days. An additional 3-4 days of malaise follows before the affected individual feels better. An individual is contagious 1-2 days prior to the appearance of the blisters until all blisters are crusted over. Generally, healthy individuals recover without complications.
- A highly contagious infectious disease caused by the varicella-zoster virus (herpesvirus 3, human). It usually affects children, is spread by direct contact or respiratory route via droplet nuclei, and is characterized by the appearance on the skin and mucous membranes of successive crops of typical pruritic vesicular lesions that are easily broken and become scabbed. Chickenpox is relatively benign in children, but may be complicated by pneumonia and encephalitis in adults. (from Dorland, 27th ed)
- Chickenpox is an infectious disease caused by the varicella virus. Most cases occur in children under age 15 but older children and adults can get it. It spreads very easily from one child to another.symptoms include an uncomfortable, itchy rash, fever and headache. The rash is like blisters and usually appears on the face, scalp or trunk. The disease is usually mild and lasts 5 to 10 days, but it sometimes causes serious problems. Adults and older children tend to get sicker from it. Do not give aspirin to anyone sick with chickenpox since the combination might cause reye syndrome. Once you catch chickenpox, the virus usually stays in your body forever. You probably will not get chickenpox again, but the virus can cause shingles in adults. A chickenpox vaccine can help prevent most cases of chickenpox, or make it less severe if you do get it.

- Highly contagious infectious disease caused by the varicella-zoster virus (herpesvirus 3); usually affects children, is spread by direct contact or respiratory route via droplet nuclei, and is characterized by the appearance on the skin and mucous membranes of successive crops of typical pruritic vesicular lesions that are easily broken and become scabbed; chickenpox is relatively benign in children, but may be complicated by pneumonia and encephalitis in adults.
