Coverage Summary

UnitedHealthcare Nebraska Medical Policy CS069NE.T addresses the medical necessity and exclusions for Light and Laser Therapy (including pulsed dye laser, fractional ablative lasers, and laser hair removal) for specified cutaneous conditions and pilonidal sinus disease in Nebraska. The policy is effective February 1, 2026 and takes a mixed coverage stance: some indications (e.g., pulsed dye laser for port-wine stains and hemangiomata; laser hair removal as adjunct for pilonidal sinus disease; fractional ablative laser fenestration for hypertrophic burn scars when criteria met) are proven and medically necessary, while multiple other light/laser applications (e.g., acne, onychomycosis, rosacea, rhinophyma) are considered unproven and not medically necessary due to insufficient evidence.

Medically-Necessary Criteria

Laser hair removal — Pilonidal sinus disease

Covered when ALL of the following are met:

Laser hair removal — Pilonidal sinus disease: Laser hair removal is used for treatment of pilonidal sinus disease that has been or is being treated with surgery for control of hair regrowth

Proven and medically necessary as adjunct to surgical management

Fractional ablative laser fenestration — Hypertrophic burn scars

Covered when ALL of the following are met:

Fractional ablative laser fenestration — Hypertrophic burn scars: Burn scar is causing functional impairment (i.e., limiting range of motion) and treatment can be reasonably expected to improve functional impairment

Fractional ablative laser fenestration — Hypertrophic burn scars: Individual has tried and failed at least one conventional treatment (e.g., hypoallergenic paper tape, pressure garments, or silicone kits with gel/sheeting)

Prior conventional treatment failed (threshold: at least one conventional therapy)

Not Medically Necessary / Excluded Indications

Not medically necessary (excluded) indications

The following light and laser therapies are considered unproven and not medically necessary due to insufficient evidence:

Not medically necessary (excluded) indications: Acne vulgaris

Unproven / not medically necessary

Not medically necessary (excluded) indications: Onychomycosis

Unproven / not medically necessary

Not medically necessary (excluded) indications: Rhinophyma

Evidence Summary & Guideline Recommendations

Evidence-based conclusions and guideline recommendations

Summarized findings and recommendations from systematic reviews, trials, and professional guidelines:

Guidelines — NICE: NICE: 'consider' recommendation for photodynamic therapy (PDT) for people aged 18 and over with moderate to severe acne if other treatments are ineffective, not tolerated, or contraindicated; no recommendation for other forms of light therapy.

NICE guideline (2021, updated 2023)

Guidelines — AAD: AAD (2024): evidence insufficient to develop recommendations on use of laser and light-based devices or PDT with aminolevulinic acid for acne; calls for RCTs with long-term follow-up and comparative effectiveness research.

AAD Guideline of Care (2024)

Acne evidence synthesis: Systematic reviews and meta-analyses report limited/low to very low quality evidence, heterogeneity, short follow-up, risk of bias; PDT may improve inflammatory acne in some studies but overall evidence is insufficient.

Provider Actions & Documentation Requirements

Documentation Required

Medical record documentation required

The patient's medical record must contain documentation that fully supports the medical necessity for the requested services. Documentation should be legible, maintained in the patient's medical record, and made available upon request. Records must substantiate the clinical indication, treatment parameters, treatment response, and any rationale for deviation from standard approaches.

Examples of required documentation: relevant medical history (e.g., onset, duration, prior therapies), physical examination findings, diagnostic test results (e.g., cultures, imaging, biopsy, laboratory tests), and treatment notes (including device/settings and number of sessions).
Dates of service and provider identity (printed name and credentials) should be included.
Progress notes documenting clinical response, adverse events, and justification for continued therapy or additional courses.

On This Page

Light and laser therapies are studied across a broad range of dermatologic and related conditions. The flashlamp-pumped pulsed dye laser (PDL, commonly 595 nm) is established as the gold-standard vascular laser for port-wine stains (PWS) and is widely used for infantile hemangiomas, with numerous systematic reviews reporting high clearance rates and low rates of permanent adverse effects. Laser hair removal (LHR/LHD) is used as an adjunct in pilonidal sinus disease because hair in the natal cleft contributes to disease recurrence. Fractional ablative lasers (AFL-CO2/Er:YAG) are increasingly used for hypertrophic burn scars and have shown improvements in validated scar scales (VSS/POSAS), scar thickness, pliability, pain, and sometimes range of motion. For acne, onychomycosis, rosacea and rhinophyma, studies are heterogeneous, often small or uncontrolled, and evidence quality is generally low-to-very-low; guideline bodies (e.g., NICE, AAD) either offer limited conditional guidance (NICE: consider PDT for adults with moderate-to-severe acne when other treatments fail) or state evidence is insufficient to make recommendations for many light/laser modalities.

Documentation Required

Adjunctive use for onychomycosis

For use of light/laser therapy as adjunctive treatment for onychomycosis, document combination therapy details, prior antifungal history, and treatment parameters. Note that evidence for laser monotherapy is limited.

Document concurrent or planned topical/systemic antifungal therapy and rationale for adjunctive laser use.
Record treatment parameters (device type, wavelength, energy settings, number of sessions, intervals between sessions) and clinical response.
Document prior history with antifungal agents (topical and systemic), reasons for discontinuation or failure, and any contraindications to systemic therapy.
Note: Limited evidence supports laser monotherapy for onychomycosis; documentation should justify deviation from standard antifungal regimens.

Billing Rule

Coding clarification for warts

Coding clarification for warts: CPT codes for destruction of cutaneous vascular proliferative lesions (17106, 17107, 17108) should not be used to report treatment of viral or plantar warts.

Do not report 17106, 17107, 17108 for viral warts or plantar warts; these codes are specific to cutaneous vascular proliferative lesions.
Listed CPT codes: 17106, 17107, 17108.

Billing Rule

Removal of CPT 96999

CPT 96999 has been removed from the Applicable Codes list and should not be relied upon for reporting light and laser therapy procedures in this policy.

CPT 96999 removed from Applicable Codes — do not use as a substitute for appropriate specific CPT codes or unlisted procedure codes when applicable.

Updated list of examples of unproven and not medically necessary light and laser therapies; removed 'excimer' from the unproven/not medically necessary list. Removed language indicating excimer laser therapy is considered cosmetic and not medically necessary for treatment of vitiligo.
