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.
The differential diagnosis for HZ includes herpes simplex virus, impetigo, candidiasis, contact dermatitis, insect bites, autoimmune blistering disease, dermatitis herpetiformis, and drug eruptions.
The rash is initially an erythematous, maculopapular rash, but over the next 7-10 days, it progresses to pustules and ulceration, with crusts, scabbing or both. Post-inflammatory hyperpigmentation may develop along the affected dermatome(s) as part of the healing process.
People with herpes zoster develop a rash that looks like chickenpox. It can cause itching, burning, and pain. 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.
In some cases, shingles may cause some early symptoms that develop a few days before the painful rash first appears. These early symptoms can include: a headache. burning, tingling, numbness or itchiness of the skin in the affected area.
Stages of Shingles The second, or acute, phase is characterized by a dermatomal rash, often accompanied by unbearable itching, pain, and allodynia (site pain in response to innocuous stimuli such as clothing or wind). The rash typically lasts 7 to 10 days, with the majority of patients healing within 4 weeks.
The blisters may look like chickenpox, but they are clustered together. The shingles rash can vary in color, depending on your skin tone. On darker skin, the rash may be pink, grayish, dark brown, or even purple. On lighter skin, it will be red.
Health care providers can usually diagnose chickenpox or shingles with a visual examination. Tests are sometimes ordered to check for immunity to the varicella zoster virus (VZV). You have immunity if you've had chickenpox before or have had the chickenpox vaccine.
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.
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).
Less commonly, the rash can be more widespread and affect three or more dermatomes. This condition is called disseminated zoster. This generally occurs only in people with compromised or suppressed immune systems. Disseminated zoster can be difficult to distinguish from varicella.
Varicella-zoster is the virus that causes varicella (chicken pox), herpes zoster (shingles), and rarely, severe disseminated disease including diffuse rash, encephalitis, hepatitis, and pneumonitis. Disseminated disease is most often seen in immunocompromised patients.
Shingles can sometimes be mistaken for another skin conditions, such as hives, psoriasis, or eczema. Share on Pinterest A doctor should always be consulted if shingles is suspected. The characteristics of a rash may help doctors identify the cause.
Ramsay Hunt syndrome is a painful rash around the ear, on the face, or on the mouth. It occurs when the varicella-zoster virus infects a nerve in the head.
Zoster sine herpete (ZSH) is one of the atypical clinical manifestations of herpes zoster (HZ), which stems from infection and reactivation of the varicella-zoster virus (VZV) in the cranial nerve, spinal nerve, viscera, or autonomic nerve.
Skin allergies and stress are two common causes of skin rashes, but an allergic skin reaction can look very similar to the shingles rash—making the two skin conditions difficult to differentiate.
