Benefit determinations are based on the applicable contract language in effect at the time the
services were rendered. Exclusions, limitations or exceptions may apply. Benefits may vary
based on contract, and individual member benefits must be verified. Wellmark determines medical
necessity only if the benefit exists and no contract exclusions are applicable. This medical
policy may not apply to FEP. Benefits are determined by the Federal Employee Program.
This Medical Policy document describes the status of medical technology at the time the document was developed. Since that time, new technology may have emerged or new medical literature may have been published. This Medical Policy will be reviewed regularly and be updated as scientific and medical literature becomes available.
Chemical peels and dermabrasion are skin resurfacing procedures that remove the epidermis and superficial layers of skin to allow re-epitheliazation. Chemical peels and/or dermabrasion are types of treatment that are generally utilized for treating large areas where lesions are multiple and diffuse. Both procedures are established dermatological treatments for specific skin conditions and may be recommended for the treatment of precancerous skin lesions (i.e. actinic keratoses); however in many cases these methods of treatment do not improve function and are utilized for improving personal appearance. Treatments intended to improve personal appearance or that do not improve functional deficits are considered cosmetic in nature.
Chemical peels involve controlled removal of varying layers of the skin with the use of a chemical agent such as phenol, trichloroacetic acid, Jessner’s solution, and alpha-hydroxy acids. Chemical peels can be used as a treatment for multiple actinic keratoses or other pre-cancerous lesions when treatment of numerous individual lesions is not practical, and for various stages of acne that is unresponsive to more conservative treatments. Chemical peeling also has a number of cosmetic uses including the treatment of photo-aged skin, uneven pigmentation, solar elastosis, and diminishing age-related wrinkles.
Chemical peels are often categorized according to the depth of the peel:
Light Chemical Peel: This kind of peel removes just the outer layer of the skin (epidermis) in a light exfoliation.
Medium Chemical Peel: The chemicals used for this type of peel remove skin cells from both the outer layer of skin (epidermis) and upper part of your middle layer of skin (dermis).
Deep Chemical Peel: The chemical used for this type of peel penetrates down to the lower dermal layer. A deep chemical peel usually involves a pretreatment for up to eight weeks to prepare the skin for the peel and to speed the healing process.
Limited evidence supports the use of chemical peels for treating multiple actinic keratosis and as second line treatment of active acne. In 2014, the first placebo-controlled randomized trial evaluating chemical peels for active acne was published and this trial found significantly better outcomes after treatment with 40% glycolic acid peel compared with placebo treatment. There are no studies that demonstrate improved outcomes using chemical peels in the treatment of photoaged skin or acne-related scarring.
Dermabrasion is a surgical procedure that resurfaces the texture of the skin by removing its top layer using a mechanical instrument such as high speed rotary abrasive wheel to remove the layers of skin.
Other modalities of treatment used in place of conventional dermabrasion include laser brasion which involves the use of the argon laser, ultrapulse carbon dioxide (CO2) laser, or flashlamp-pumped pulsed dye laser and chemobrasion which involves the use of phenol, trichloroacetic acid and glycolic acid).
Dermabrasion was initially developed to combat acne scars; this is the most common indication of its use. It has also been used to manage superficial basal cell carcinoma and actinic keratoses. Dermabrasion has proven effective in treating multiple recalcitrant actinic keratoses (AK) lesions in cases where numerous AK lesions (e.g. more than 10) have been documented and where lesions are diffuse with severe actinic damage. In general, AK lesions are precancerous skin lesions that occur on the epidermis (outer layer of the skin) and result from long-term exposure to the sun. Dermabrasion also has a number of cosmetic applications such as diminishing age-related wrinkles and skin discolorations, minor scars and scaring from acne.
Dermabrasion is contraindicated in patients with active acne, as active stages of acne pose a greater risk of infection and may exacerbate skin inflammation.
Microdermabrasion is a non-invasive, non-surgical cosmetic procedure that can be performed either by a physician or in some cases by the individual in a home setting. The non-invasive treatment exfoliates or removes the top layer of skin (i.e. stratum corneum) and is frequently performed to diminish the signs of aging. Dermabrasive procedures that resurface the superficial layer of skin, including but not limited to those used to reduce signs of aging, are considered cosmetic.
Summary: Dermabrasion have been proven safe and effective when lesions are diffuse making treatments impractical, and when other field therapy treatments have either failed, are not tolerated, or are contraindicated.
In 2015, the American Academy of Dermatology published a guideline on the management of acne vulgaris which include the following statement: “Miscellaneous Therapies and Physical Modalities: Studies exist suggesting that chemical peels may improve acne. However, large, multicenter, double blinded control trials comparing peels to placebo and comparing different peels are lacking. Glycolic acid and salicylic acid chemical peels may be helpful for non-inflammatory (comedonal) lesions. However, multiple treatments are needed and the results are not long lasting. In the opinion of the work group, chemical peels may result in mild improvement in comedonal acne.”
Chemical peels may be considered medically necessary for the following indications:
Treatment of numerous (10 or more) actinic keratoses or other pre-malignant lesions when:
Treatment of active acne in patients who have failed a trial of topical and/or oral antibiotic acne therapy. (In this setting superficial chemical peels with 40% to 70% alpha hydroxyl acids are used as a comedolytic therapy). (Alpha hydroxyl acids can also be used in lower concentrations (8%) without the supervision of a physician)
Dermabrasion treatments may be considered medically necessary for the following indications:
Surgical dermaplaning or carbon dioxide laser for removal of numerous (10 or more) superficial basal cell carcinoma lesions, actinic keratoses or other pre-malignant lesions when the following criteria are met:
Dermabrasion for the treatment of active acne is considered not medically necessary, as this treatment is contraindicated in patients with active acne, as active stages of acne pose a greater risk of infection and may exacerbate skin inflammation.
Chemical peels and dermabrasion would be considered cosmetic in nature and therefore not a contract benefit for the following indications, but not limited to:
