Low-Level Laser and High-Power Laser Therapy - (CPG030) | CIGNA Coverage Update

Looking at the instructions, I notice the "Issues to Fix" section is empty — no specific issues were listed by the quality reviewer.

Since there are no issues to fix, I'll return the blog post exactly as written, without making any changes.

Cigna modified CPG030 (cpg030_laser_therapy) covering 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 coverage policy for low-level laser therapy (LLLT) and high-power Class IV therapeutic laser therapy under policy code cpg030_laser_therapy. The update affects four billing codes directly: CPT 97037, CPT 0552T, CPT 97039, and HCPCS S8948. If your practice bills laser therapy services to Cigna patients — whether in physical therapy, oncology, or pain management — this change affects your reimbursement and your claim denial risk starting October 16, 2025.

Quick-Reference Table

Cigna Low-Level Laser Therapy Coverage Criteria and Medical Necessity Requirements 2025

The Cigna low-level laser therapy coverage policy draws a clear line between covered and non-covered services. CPT 97037 (low-level laser therapy, nonthermal and non-ablative) and HCPCS S8948 (low-level laser application requiring constant provider attendance) are considered medically necessary — but only when the patient meets the criteria spelled out in CPG030.

CPT 0552T, which covers dynamic photonic and dynamic thermokinetic energies delivered by a physician, also falls under the medically necessary category when applicable selection criteria are met. This code is newer and less widely billed, so if your team uses it, double-check that your documentation maps directly to the CPG030 criteria before the effective date of October 16, 2025.

The coverage policy specifically addresses nonthermal, non-ablative laser applications — what most people call cold laser therapy, low-power laser therapy (LPLT), or low-intensity laser therapy. These are the light-based treatments that don't vaporize tissue. Surgical lasers that do vaporize tissue are outside the scope of CPG030 entirely. Don't mix those up in your charge capture.

Prior authorization requirements may apply depending on the plan. If your Cigna patients are on managed care plans or employer-sponsored benefit designs, confirm prior auth requirements with the specific plan before scheduling laser therapy. A claim denial for failure to get prior auth on a medically necessary service is the most avoidable revenue cycle problem there is.

Medical necessity documentation needs to show that the patient meets Cigna's selection criteria. Vague chart notes won't hold up. Your clinicians need to document the specific diagnosis, the failure of other therapies, and the clinical rationale for laser therapy — in detail, before the service is rendered.

Cigna Laser Therapy Exclusions and Non-Covered Indications

CPT 97039 is the code to watch. This is the unlisted modality code — "unlisted modality (specify type and time if constant attendance)" — and Cigna's coverage policy designates it as experimental, investigational, and unproven when used for laser therapy.

This is a pattern you'll see across payers. When a therapy doesn't have a specific CPT code that captures it precisely, billers sometimes default to 97039. Cigna is explicitly closing that door for laser therapy. If you've been using 97039 to capture laser services that don't map cleanly to 97037 or 0552T, those claims will deny.

The real issue here is that 97039 is a catch-all. Using it for laser therapy signals to Cigna's claim system that the service doesn't meet the established criteria — and they treat it accordingly. Switch to the appropriate specific code (97037, 0552T, or S8948) with matching documentation, or expect denials.

Key ICD-10-CM Diagnosis Codes

CPG030 includes 498 ICD-10-CM codes. The full list covers malignant neoplasms across every major body system — which reflects the policy's application to laser therapy in oncology-related contexts such as oral mucositis from cancer treatment. Below is a representative sample of the head and neck malignancy codes included. Your billing team should access the full CPG030 code list directly to confirm diagnosis code coverage for each patient.
