Light Therapy for Psoriasis

Policy Number: MP-009

Latest Review Date: March 2024

Category: Medical                                                     

POLICY:

Targeted phototherapy for the treatment of localized psoriasis may be considered medically necessary when:

  1. Treatment is for localized, symptomatic psoriasis of the hands, feet, knees, elbows, scalp, or face and conventional treatment has failed.  Conventional treatment may include sunlight, topical steroids, coal tar preparations, calcipotriene (Dovonex®), vitamin A (Tazarotene®), Anthralin®, salicylic acid, and other forms of light therapy. For conventional treatment to be considered a failure an adequate trial of the therapy should be documented.

  2. Total treatment area should be no more than 20% of the body surface.
  3. May be used to treat resistant lesions.
  4. No more than 10 sessions per course of treatment.  A session should include all areas treated on a day.
  5. An additional course of treatment may be necessary if the individual’s psoriasis responded positively to the initial course of treatment and then worsened over time.

Psoralen plus ultraviolet A (PUVA) may be considered medically necessary for the treatment of severe, disabling psoriasis, which is not responsive to other forms of conservative therapy (e.g., topical corticosteroids, coal/tar preparations, and ultraviolet light).

Ultraviolet B with the addition of topical coal tar (also known as Goeckerman treatment) or petrolatum may be considered medically necessary for coverage for severe psoriasis (defined as psoriasis that affects more than 10% of the body surface area).

Ultraviolet B with the addition of topical coal tar (also known as Goeckerman treatment) or petrolatum is considered investigational for all other indications.

Ultraviolet B light therapy administered in the home may be considered medically necessary for the following conditions and when conducted under a physician’s supervision with regularly scheduled exams:

  • Psoriasis-mild to moderate forms when conventional treatment has failed
  • Severe psoriasis

Targeted phototherapy, as the first-line treatment of mild psoriasis, is considered investigational.

Targeted phototherapy for the treatment of generalized psoriasis or psoriatic arthritis is considered investigational.

DESCRIPTION OF PROCEDURE OR SERVICE:

Light therapy for psoriasis includes both targeted phototherapy and photochemotherapy with psoralen plus ultraviolet A (PUVA). Targeted phototherapy describes the use of ultraviolet light that can be focused on specific body areas or lesions. PUVA uses a psoralen derivative in conjunction with long wavelength ultraviolet A (UVA) light (sunlight or artificial) for photochemotherapy of skin conditions.

Psoriasis

Psoriasis is a common chronic immune-mediated disease characterized by skin lesions ranging from minor localized patches to complete body coverage. There are several types of psoriasis; most common is plaque psoriasis, which is associated with red and white scaly patches on the skin. In addition to being a skin disorder, psoriasis can negatively impact many organ systems and is associated with an increased risk of cardiovascular disease, some types of cancer, and autoimmune diseases (e.g., celiac disease, Crohn disease). Although disease severity is minimally defined by body surface area, (mild psoriasis affects 10% of body surface area), lesion characteristics (e.g., location and severity of erythema, scaling, induration, pruritus) and impact on QOL are also taken into account.

Treatment of Psoriasis

Topical therapy (e.g., corticosteroids, vitamin D analogs) is generally considered to be a first-line treatment of psoriasis, especially for mild disease. Phototherapy and systemic therapy are treatment options for individuals with more extensive and/or severe disease and those who fail conservative treatment with topical agents. Phototherapy is available in various forms including exposure to natural sunlight, use of broadband ultraviolet B (BB-UVB) devices, narrowband (NB-UVB) devices and psoralen plus ultraviolet A (PUVA). This policy addresses 2 treatments: PUVA and targeted phototherapy, i.e., use of ultraviolet light that can be focused on specific body areas or lesions.

Psoralen plus Ultraviolet A

Psoralens with UVA (PUVA) uses a psoralen derivative in conjunction with long-wavelength UVA light (sunlight or artificial) for photochemotherapy of skin conditions. Psoralens are tricyclic furocoumarin that occur in certain plants and can also be synthesized. They are available in oral and topical forms. Oral PUVA is generally given 1.5 hours before exposure to UVA radiation. Topical PUVA therapy refers to directly applying the psoralen to the skin with subsequent exposure to UVA light. Bath PUVA is used in some European countries for generalized psoriasis, but the agent used, trimethylpsoralen, is not approved by the U.S. Food and Drug Administration (FDA). Paint and soak PUVA are other forms of topical application of psoralen and are often used for psoriasis localized to the palms and soles. In paint PUVA, 8-methoxypsoralen (8-MOP) in an ointment or lotion form is put directly on the lesions. With soak PUVA, the affected areas of the body are placed in a basin of water containing psoralen. With topical PUVA, UVA exposure is generally administered within 30 minutes of psoralen application.

PUVA has most commonly been used to treat severe psoriasis, for which there is no generally accepted first-line treatment. Each treatment option (e.g., systemic therapies such as methotrexate, phototherapy, biologic therapies, etc.) has associated benefits and risks. Common minor toxicities associated with PUVA include erythema, pruritus, irregular pigmentation, and gastrointestinal tract symptoms; these generally can be managed by altering the dose of psoralen or UV light. Potential long-term effects include photoaging and skin cancer, particularly squamous cell carcinoma (SCC) and possibly malignant melanoma. PUVA is generally considered more effective than targeted phototherapy for the treatment of psoriasis. However, the requirement of systemic exposure and the higher risk of adverse reactions (including a higher carcinogenic risk) have generally limited PUVA therapy to individuals  with more severe cases.

Targeted Phototherapy

Potential advantages of targeted phototherapy include the ability to use higher treatment doses and to limit exposure to surrounding tissue. Broadband (BB)-UVB devices, which emit wavelengths from 290 to 320 nanometeres (nm) have been largely replaced by narrowband (NB)-UVB devices. NB-UVB devices eliminate wavelengths below 296 nm, which are considered erythemogenic and carcinogenic but not therapeutic. NB-UVB is more effective than BB-UVB and approaches PUVA in efficacy. Original NB-UVB devices consisted of a Phillips TL-01 fluorescent bulb with a maximum wavelength (lambda max) at 311 nm. Subsequently, xenon chloride (XeCl) lasers and lamps were developed as targeted NB-UVB treatment devices; they generate monochromatic or very narrow band radiation with a lambda max of 308 nm. Targeted phototherapy devices are directed at specific lesions or affected areas, thus limiting exposure to the surrounding normal tissues. They may therefore allow higher dosages compared to a light box, which could result in fewer treatments to produce clearing. The original indication of the excimer laser was for individuals with mild to moderate psoriasis, defined as involvement of less than 10% of the skin. Newer XeCl laser devices are faster and more powerful than the original models, which may allow the treatment of individuals with more extensive skin involvement, 10–20% of body surface area.

KEY POINTS:

This policy is regularly updated with the most recent literature review through March 21, 2024.

Summary of Evidence

For individuals who have mild localized psoriasis, the evidence is lacking on the use of targeted phototherapy. Relevant outcomes are symptoms, change in disease status, quality of life (QOL), and treatment-related morbidity. The American Academy of Dermatology does not recommend phototherapy for individuals with mild localized psoriasis whose disease can be controlled with topical medications. The evidence is insufficient to determine the effects of the technology on health outcomes.

For individuals who have mild psoriasis that is resistant to topical medications who receive targeted phototherapy, the evidence includes some small (N<60) within-subject studies. The relevant outcomes are symptoms, change in disease status, QOL, and treatment-related morbidity. Studies show that targeted phototherapy can improve mild localized psoriasis that has not responded to topical treatment. Targeted phototherapy is presumed to be safer or at least no riskier than whole body phototherapy, due to risks of exposing the entire skin to the carcinogenic effects of UVB light. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.

For individuals who have moderate-to-severe localized psoriasis who receive targeted phototherapy, the evidence includes systematic reviews of small (N≤25) controlled trials (randomized controlled trials [RCTs] and non-RCTs). Relevant outcomes are symptoms, change in disease status, QOL, and treatment-related morbidity. Systematic reviews of small controlled trials in individuals with moderate-to-severe psoriasis have found that targeted phototherapy has efficacy similar to whole-body phototherapy. Targeted phototherapy is presumed to be safer or at least no riskier than whole body phototherapy, due to risks of exposing the entire skin to the carcinogenic effects of UVB light. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.

For individuals who have generalized psoriasis who receive PUVA, the evidence includes RCTs and systematic reviews of RCTs. Relevant outcomes are symptoms, change in disease status, QOL, and treatment-related morbidity. The available evidence demonstrates that PUVA is more effective than narrow band-UVB phototherapy, topical steroids, or ultraviolet A without psoralens in individuals with generalized psoriasis. Due to side effects, PUVA is typically restricted to more severe cases. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.

Practice Guidelines and Position Statements

American Academy of Dermatology

The American Academy of Dermatology 2010 guideline on the management of psoriasis recommended individuals with psoriasis who are compliant could, under dermatologist supervision, be considered appropriate candidates for home UVB therapy. Targeted phototherapy was recommended for individuals with mild, moderate, or severe psoriasis with less than 10% involvement of the body surface area. Systematic PUVA with ultraviolet A is indicated in adults with generalized psoriasis who are resistant to topical therapy.

National Psoriasis Foundation

In 2017, the National Psoriasis Foundation published a consensus guidance based on a task force review of the literature on the treatment for psoriasis involving skinfolds (inverse or intertriginous) psoriasis. The treatment guidance for intertriginous or genital psoriasis stated: “…there is anecdotal evidence demonstrating the strong clinical efficacy of biologic treatment; with limited knowledge on the effects of biologics on intertriginous or genital psoriasis.” The guidance on inverse psoriasis is provided in Table 2.

Table 2. Recommendations on Treatment of Inverse Psoriasis

Line of Therapy

Recommendation

First-line therapy

Low potency topical steroids for periods less than 2-4 wks

 

Other topical therapies to consider are tacrolimus, pimecrolimus, calcitriol, or calcipotriene to avoid steroid side effects with long-term treatment

Second- and third-line therapies

Antimicrobial therapy, emollients, and tar-based products

 

Axillary involvement can be treated with botulinum toxin injection to reduce perspiration and inhibit inflammatory substance release

 

Excimer laser therapy or systemic agents

In 2017, the National Psoriasis Foundation also published recommendations based on a review of the literature on the treatment for psoriasis in solid organ transplant individuals. Because organ transplant individuals are excluded from randomized controlled trials, there are limited data. The recommendations were based on case series (see Table 3).

NB-UVB: narrowband ultraviolet B; UVB: ultraviolet B.

The guidelines state of home NB-UVB therapy that evidence shows similar results regarding efficacy, quality of life, and side effects between individuals with mild-to-severe psoriasis who received home treatments and those who received treatments at hospitals. In addition, home treatment was found to significantly lessen the burden on individuals who had to travel to a phototherapy center.

Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.

 

This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.

The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.

As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.

The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:

1. The technology must have final approval from the appropriate government regulatory bodies;

2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;

3. The technology must improve the net health outcome;

4. The technology must be as beneficial as any established alternatives;

5. The improvement must be attainable outside the investigational setting.

 

Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:

1. In accordance with generally accepted standards of medical practice; and

2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and

3. Not primarily for the convenience of the patient, physician or other health care provider; and

   4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent

      therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
