Common complications of herpes zoster infections include acute pain, postherpetic neuralgia, persistent neuropathy, hemorrhage, ulceration, necrosis, myonecrosis, necrosis of bone, and (uncommonly) secondary bacterial infection.
Genital herpes is caused by herpes simplex 2. The condition we call shingles is caused by herpes zoster. Herpes zoster is the same viral infection that causes chicken pox, and the herpes zoster virus can live in the body for years after the case of chicken pox is gone, and re-emerge as the painful blisters of shingles.
Herpes zoster, also known as shingles, is caused by the reactivation of the varicella-zoster virus (VZV), the same virus that causes varicella (chickenpox). Primary infection with VZV causes varicella.

The note in ICD-10 under codes B95-B97 states that 'these categories are provided for use as supplementary or additional codes to identify the infectious agent(s) in disease classified elsewhere', so you would not use B96. 81 as a primary diagnosis, but as an additional code with the disease listed first.
Our physicians have used IDC-10 code F07. 81 as the primary diagnosis for patients presenting with post concussion syndrome.
What causes herpes zoster? Herpes zoster is caused by the reactivation of the chickenpox virus. After a person has had chickenpox, the virus lies dormant in certain nerves for many years.
The most common complication of shingles is long-term nerve pain called postherpetic neuralgia (PHN).
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.
