ICD-10 code B02 for Zoster [herpes zoster] is a medical classification as listed by WHO under the range - Certain infectious and parasitic diseases .
Shingles is classified to ICD-9-CM category 053.
Shingles is a painful rash that develops on one side of the face or body. The rash consists of blisters that typically scab over in 7 to 10 days and fully clears up within 2 to 4 weeks. Before the rash appears, people often have pain, itching, or tingling in the area where it will develop.
Disseminated herpes zoster is usually defined as a generalized eruption of more than 10-12 extradermatomal vesicles occurring 7-14 days after the onset of classic dermatomal herpes zoster. Typically, it is clinically indistinguishable from varicella (chickenpox).
ICD-10 code R21 for Rash and other nonspecific skin eruption is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
Shingles is caused by varicella zoster virus (VZV), the same virus that causes chickenpox. After a person recovers from chickenpox, the virus stays dormant (inactive) in their body. The virus can reactivate later, causing shingles. Most people who develop shingles have only one episode during their lifetime.
Shingles' clinical manifestations are divided into 3 distinct phases: preeruptive, acute eruptive, and chronic. The preeruptive phase (or preherpetic neuralgia stage) usually lasts about 48 hours but can stretch to 10 days in some cases.
Herpes zoster, also known as shingles, is a condition usually characterised by pain, followed by the development of a vesicular rash, which is unilateral and typically affects one dermatome.
With localized herpes zoster, the rash usually appears as a wide strip on one side of the body. With disseminated (more widespread) herpes zoster, the rash covers a wider area of the body.
Herpes zoster (HZ) also known as shingles is a common dermatological pathology seen in the emergency department. Multidermatomal involvement is an uncommon presentation and usually is linked to immunocompromised individuals. However, it is rarely reported in the immunocompetent population.
In general, as long as the lesion can be covered, a person with shingles does not need to stay home from work or school. Health care workers and others working with high-risk individuals should remain home from work until the blisters have scabbed over.
