Cigna modified CPG030 for low-level laser therapy and high-power laser therapy, effective October 16, 2025. Here's what billing teams need to do.
Cigna Healthcare updated its laser therapy coverage policy — CPG030 in the Cigna system — covering low-level laser therapy (LLLT) and high-power Class IV therapeutic laser therapy. The update affects four codes directly: CPT 97037, CPT 0552T, CPT 97039, and HCPCS S8948. If your practice bills any of these for physical medicine, rehabilitation, or pain management, this policy change affects your reimbursement and your denial risk starting October 16, 2025.

Cigna Low-Level Laser Therapy Coverage Criteria and Medical Necessity Requirements 2025
The Cigna laser therapy coverage policy draws a hard line between two types of laser treatment. LLLT — also called cold laser therapy, low-power laser therapy (LPLT), low-intensity laser therapy, and low-energy laser therapy — falls under this policy. So does high-power Class IV therapeutic laser light therapy. What's not covered here: surgical lasers that vaporize tissue. That's a separate policy. Don't mix them up.
For CPT 97037 and HCPCS S8948, Cigna considers these codes medically necessary when the patient meets the criteria in the applicable coverage policy. CPT 97037 specifically covers application of a low-level laser modality — nonthermal and non-ablative — to one or more areas. HCPCS S8948 covers the same modality but requires constant provider attendance. Both codes have a path to reimbursement, but only when documentation supports medical necessity.
CPT 0552T is the code for low-level laser therapy using dynamic photonic and dynamic thermokinetic energies, provided by a physician. Cigna also considers this medically necessary when the applicable criteria are met. The operative phrase is "when criteria are met" — and that means your documentation has to show why this patient, this condition, and this treatment align with what the policy requires.
Before billing any of these codes, confirm whether prior authorization is required under your patient's specific Cigna plan. Cigna plan requirements vary by product line. If your billing guidelines don't already flag laser therapy codes for prior auth verification, add that check now.
Cigna Low-Level Laser Therapy Exclusions and Non-Covered Indications
CPT 97039 is the code to watch. Cigna classifies it as experimental, investigational, and unproven when used for laser therapy purposes.
CPT 97039 is an unlisted modality code — it requires you to specify type and time if constant attendance applies. The problem is that using it as a workaround when 97037 doesn't fit will trigger a denial under this policy. Cigna isn't leaving room for interpretation here. If you're using 97039 to bill laser therapy for Cigna patients, that claim is headed for a claim denial.
This is the highest-risk element of CPG030 for most billing teams. Unlisted codes are tempting when a service feels like it doesn't fit a defined code. But Cigna's position is explicit: 97039 for laser therapy is not covered. If you've been using it, stop before October 16, 2025.
Coverage Indications at a Glance
| Indication / Use | Status | Relevant Codes | Notes |
|---|---|---|---|
| Low-level laser therapy (LLLT / cold laser / LPLT) to one or more areas | Covered when criteria met | CPT 97037, HCPCS S8948 | Medical necessity documentation required; S8948 requires constant provider attendance |
| LLLT using dynamic photonic and dynamic thermokinetic energies, physician-provided | Covered when criteria met | CPT 0552T | Must meet applicable CPG030 criteria |
| Unlisted modality used for laser therapy purposes | Experimental / Not Covered | CPT 97039 | Cigna considers this experimental, investigational, and unproven for laser therapy |
| Surgical lasers / tissue vaporization | Not addressed by CPG030 | N/A | Covered under a separate Cigna policy — do not bill under CPG030 |
| High-power Class IV therapeutic laser light therapy | Addressed by CPG030 | CPT 97037, 0552T, S8948 | Coverage depends on meeting applicable criteria |
Cigna Laser Therapy Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit every claim template that includes CPT 97039 for laser therapy before October 16, 2025. Cigna's experimental designation is explicit. Any open or pending claims using 97039 for LLLT need review now. Don't wait for a denial to surface — pull them proactively. |
| 2 | Map your laser therapy services to the correct covered codes. If your service is LLLT applied to one or more areas, CPT 97037 is the right code. If the provider is in constant attendance, consider HCPCS S8948. If the service involves dynamic photonic and dynamic thermokinetic energies billed by a physician, CPT 0552T applies. Each code has a distinct clinical scenario. Match the code to the service. |
| 3 | Verify prior authorization requirements by plan before the effective date. Cigna's prior authorization rules differ by plan type — commercial, Medicare Advantage, and employer-sponsored plans don't always follow the same rules. Check each patient's plan before scheduling or billing. |
| 4 | Update your documentation templates to support medical necessity criteria. Cigna's coverage policy requires that claims meet the "applicable criteria" — which means your clinical notes need to reflect those criteria. Work with your medical director or treating providers to make sure documentation captures the elements Cigna expects. Vague notes are the second-fastest path to a claim denial after wrong code selection. |
| 5 | Flag CPT 0552T for additional scrutiny. This is a Category III code, and some payers treat it differently than Category I codes in their billing guidelines. Cigna recognizes it as medically necessary when criteria are met, but clearinghouses and billing systems sometimes handle T-codes inconsistently. Test your charge capture before October 16, 2025 to make sure 0552T routes correctly. |
| 6 | If you bill HCPCS S8948, document constant attendance. S8948 specifically requires constant provider attendance. If your notes don't support that level of direct supervision, you're billing the wrong code — or billing without adequate support. Either way, it's a denial waiting to happen. |
| 7 | Talk to your compliance officer if you're unsure how this applies to your payer mix. CPG030 covers multiple laser therapy modalities with different coverage statuses. If your practice uses multiple laser types or bills a high volume of LLLT claims to Cigna, get a compliance review before the effective date of October 16, 2025. |
