Shingles is classified to ICD-9-CM category 053.
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 viral syndrome caused by reactivation of the varicella-zoster virus. After an episode of varicella (chicken-pox), the varicella-zoster virus remains dormant in the nervous system. Herpes zoster typically occurs in adults or elderly.
Allergic contact dermatitis, unspecified cause L23. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM L23. 9 became effective on October 1, 2021.
Irritant contact dermatitis is the most common type. This nonallergic skin reaction occurs when an irritant damages your skin's outer protective layer. Some people react to strong irritants after a single exposure. Others may develop a rash after repeated exposures to even mild irritants, such as soap and water.

Medicaid Billing Providers must bill with CPT code: 90750 - Zoster (shingles) vaccine, (HZV), recombinant, sub-unit, adjuvanted, for intramuscular injection. One Medicaid unit of coverage is 0.5 mL. The maximum reimbursement rate per unit is $144.20.
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.
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).
