ICD-10 code B02 for Zoster [herpes zoster] is a medical classification as listed by WHO under the range - Certain infectious and parasitic diseases .
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).
Shingles is classified to ICD-9-CM category 053.
Herpes zoster, or shingles, is a common viral infection of the nerves, which results in a painful rash of small blisters on a strip of skin anywhere on the body. Even after the rash is gone, the pain may continue for months.
Shingles causes a red rash that forms a band on one side of your body or face. The rash can appear anywhere on your body or in several places. The second most common rash site is the face. It can spread from the ear to the nose and forehead.
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.

The differential diagnosis for HZ includes herpes simplex virus, impetigo, candidiasis, contact dermatitis, insect bites, autoimmune blistering disease, dermatitis herpetiformis, and drug eruptions.
Since stress affects the immune system, many researchers believe that stress could be a trigger for shingles. Researchers in multiple studies have linked chronic, daily stress, and highly stressful life events as risk factors for shingles.
About 1 out of every 3 people in the United States will develop shingles, also known as herpes zoster, in their lifetime. An estimated 1 million people get shingles each year in this country. If you've ever had chickenpox, you can get shingles.
