Cigna modified MM 0505 covering excimer laser therapy, dermabrasion, and chemical peels, effective September 26, 2025. Here's what billing teams need to do.
Cigna Healthcare updated its coverage policy for dermatologic skin resurfacing procedures under policy code MM 0505, with an effective date of September 26, 2025. This modification covers 12 CPT codes across three procedure categories: excimer laser (CPT 96920, 96921, 96922), dermabrasion (CPT 15780–15783), and chemical peels (CPT 15788, 15789, 15792, 15793, 17360). If your practice bills any of these codes for Cigna members, review your documentation and prior authorization workflows before September 26, 2025.

Cigna Excimer Laser, Dermabrasion, and Chemical Peel Coverage Criteria and Medical Necessity Requirements 2025
The Cigna excimer laser, dermabrasion, and chemical peel coverage policy under MM 0505 in the Cigna system applies to both adult and pediatric populations. Each of the three procedure categories has a distinct clinical profile, and Cigna treats them differently in terms of when medical necessity is established.
Excimer laser therapy delivers a targeted spectrum of UVB wavelengths. It treats small, focused areas of the body. CPT codes 96920, 96921, and 96922 map directly to treatment surface area — under 250 sq cm, 250–500 sq cm, and over 500 sq cm, respectively. These codes are considered medically necessary when the criteria in the applicable coverage position are met.
Dermabrasion (CPT 15780, 15781, 15782, 15783) and chemical peels (CPT 15788, 15789, 15792, 15793) are skin resurfacing procedures. They remove the epidermis and superficial layers of skin to allow re-epithelialization. Cigna's policy positions these as treatments suited for large areas where lesions are multiple and diffuse — not for isolated cosmetic improvement.
Chemical exfoliation for acne under CPT 17360 is also included. This code covers procedures like acne paste and acid treatments and is covered when medical necessity criteria are satisfied.
The real issue here is documentation. Every one of these 12 codes sits in a cosmetic-adjacent space, and Cigna will scrutinize the clinical record. Your documentation must establish the condition being treated, the area affected, and why resurfacing is medically indicated — not just aesthetically desired. Thin documentation on any of these claims is a direct path to claim denial.
ICD-10-CM code L57.0 (actinic keratosis) is the one diagnosis code explicitly referenced in this policy. If you're billing for actinic keratosis treatment using dermabrasion or chemical peel codes, L57.0 is your anchor diagnosis. Map it correctly on the claim.
Prior authorization requirements are a real concern with these procedures. Given the cosmetic overlap, many Cigna plans require prior auth before these services are rendered. Confirm your patient's specific plan requirements before scheduling. Don't assume that because a procedure meets the medical necessity standard in MM 0505, the prior authorization step is waived — those are two separate gates.
Cigna Dermabrasion and Chemical Peel Exclusions and Non-Covered Indications
The MM 0505 policy does not designate any of the 12 CPT codes as experimental or investigational. All 12 codes are listed as covered when criteria are met.
That said, "covered when criteria are met" is doing a lot of work in this policy. The cosmetic vs. medical distinction is where most claim denials originate. Dermabrasion for acne scarring is a different claim than dermabrasion for fine wrinkling or general cosmetic improvement. The procedure codes overlap across both use cases — CPT 15780 specifically lists acne scarring, fine wrinkling, rhytids, and general keratosis in its descriptor.
Your documentation needs to separate the medical indication from any cosmetic component clearly. If Cigna's reviewer can read the record and conclude the primary driver was cosmetic, the claim will not survive appeal.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Psoriasis — small area (< 250 sq cm) | Covered when criteria met | CPT 96920 | Excimer laser; document treatment area |
| Psoriasis — mid area (250–500 sq cm) | Covered when criteria met | CPT 96921 | Excimer laser; document treatment area |
| Psoriasis — large area (> 500 sq cm) | Covered when criteria met | CPT 96922 | Excimer laser; document treatment area |
| Acne scarring, rhytids, general keratosis — total face | Covered when criteria met | CPT 15780 | Dermabrasion; medical necessity documentation required |
| Acne scarring, keratosis — segmental face | Covered when criteria met | CPT 15781 | Dermabrasion; document specific facial segment |
| Dermatologic conditions — regional, non-face | Covered when criteria met | CPT 15782 | Dermabrasion; document body region treated |
| Tattoo removal or superficial skin conditions | Covered when criteria met | CPT 15783 | Superficial dermabrasion; confirm medical vs. cosmetic basis |
| Chemical peel — facial, epidermal | Covered when criteria met | CPT 15788 | Document diagnosis and clinical rationale |
| Chemical peel — facial, dermal | Covered when criteria met | CPT 15789 | Dermal depth; document clinical necessity |
| Chemical peel — nonfacial, epidermal | Covered when criteria met | CPT 15792 | Document non-facial site and diagnosis |
| Chemical peel — nonfacial, dermal | Covered when criteria met | CPT 15793 | Document non-facial site and depth |

Cigna Excimer Laser and Dermatologic Procedure Billing Guidelines and Action Items 2025
The excimer laser and dermabrasion billing landscape under MM 0505 shifts on September 26, 2025. Here are the concrete steps your billing team should take before that date.
| # | Action Item |
|---|---|
| 1 | Pull all open Cigna claims for CPT 96920, 96921, 96922, 15780–15783, 15788, 15789, 15792, 15793, and 17360. Flag any that lack a documented medical necessity narrative. Incomplete records will not survive a post-payment audit under the revised policy. |
| 2 | Update your charge capture templates to include L57.0 for actinic keratosis claims. This is the only ICD-10-CM code explicitly called out in MM 0505. If your billers are using other diagnosis codes for actinic keratosis treatment, confirm those codes still support medical necessity under the updated policy criteria. |
| 3 | Verify prior authorization requirements for each patient's specific Cigna plan before September 26, 2025. MM 0505 sets the coverage criteria, but individual plan documents control prior auth requirements. These are not the same thing. A procedure that meets MM 0505's medical necessity standard can still be denied for missing prior auth. |
| 4 | Train your clinical documentation team on the cosmetic vs. medical distinction for dermabrasion and chemical peel codes. CPT 15780 includes both acne scarring and fine wrinkling in its descriptor — two very different clinical justifications. The medical record must make the primary indication clear. Ambiguous records lose on appeal. |
| 5 | For excimer laser billing, document the treatment area in square centimeters at every visit. CPT 96920, 96921, and 96922 are differentiated by surface area. If your provider documents "psoriasis treatment" without a specific area measurement, your coder has no defensible basis for code selection. This is a basic billing compliance issue that gets practices in trouble consistently. |
| 6 | Review your reimbursement rates for these 12 codes under current Cigna fee schedules. Policy modifications sometimes accompany reimbursement adjustments. Confirm that your contracted rates are still current as of the September 26, 2025 effective date. |
| 7 | If your practice treats pediatric patients for any of these conditions, flag those cases for additional documentation review. MM 0505 explicitly covers both adult and pediatric populations. Pediatric claims for skin resurfacing procedures draw extra scrutiny. Make sure your medical necessity documentation addresses the specific clinical circumstances of a minor patient. |
If you're uncertain how this modification applies to your specific patient mix or payer contract terms, talk to your compliance officer before September 26, 2025.
