Cold Laser and High-Power Laser Therapies — CPB 0363 | AETNA Coverage Update

TL;DR: Aetna modified CPB 0363 covering cold laser and high-power laser therapies, effective March 3, 2026. CPT 97037, 0552T, and 1011T are directly affected. Here's what billing teams need to do.

Aetna's laser therapy coverage policy just got updated under CPB 0363. The policy now explicitly names CPT 1011T (photobiomodulation therapy) alongside the existing codes, while holding a hard line: the only covered indication is oral mucositis prevention in cancer patients. If your practice bills laser therapy for pain, musculoskeletal conditions, wound healing, or any of the 54 other indications listed in this policy, expect denials. Every single one of those indications lands in Aetna's "experimental, investigational, or unproven" bucket.

Aetna Cold Laser and High-Power Laser Therapy Coverage Criteria and Medical Necessity Requirements 2026

The Aetna cold laser therapy coverage policy is narrow. Painfully narrow.

Aetna recognizes exactly one covered indication under CPB 0363: prevention of oral mucositis in patients undergoing cancer treatment. That includes chemotherapy, radiotherapy, hematopoietic stem cell transplantation, or any combination of the three.

CPT 1011T — photobiomodulation (PBM) therapy of the oral cavity, including placement of an oral device and monitoring — is the primary code for this indication. CPT 0552T covers low-level laser therapy using dynamic photonic and dynamic thermokinetic energies, and it appears in the policy's "covered when selection criteria are met" group. But here's the problem: the same policy explicitly names "low-level laser therapy using dynamic photonic and dynamic thermokinetic energies" as experimental, investigational, or unproven. That's the same therapy 0552T describes. The policy doesn't resolve this tension, which means 0552T's coverage status is genuinely ambiguous under CPB 0363. Do not bill 0552T to Aetna for any indication without verifying directly with Aetna how they're applying this code. Loop in your compliance officer before you submit any 0552T claims.

Based on the policy's structure, the oral mucositis diagnosis codes K12.30, K12.31, and K12.32 appear to map to the covered indication — but the CPB text does not state this mapping explicitly. Verify the full code mapping in the original CPB before finalizing your charge capture.

The policy does not list prior authorization requirements in the CPB text. That doesn't mean prior auth isn't required at the plan level. Always verify prior authorization requirements at the individual plan level before scheduling laser therapy for any covered patient. A prior auth miss on an oncology claim can be expensive.

Reimbursement under CPT 1011T applies only when the documented clinical context ties directly to cancer treatment-related mucositis prevention. If your documentation doesn't make that connection explicit, you don't have a covered claim — you have a pending denial.

Aetna Laser Therapy Exclusions and Non-Covered Indications

This is where CPB 0363 gets blunt. Aetna considers cold laser therapy (class III, also called low-level laser therapy), high-power laser therapy (class IV therapeutic laser), and low-level laser therapy using dynamic photonic and dynamic thermokinetic energies experimental, investigational, or unproven for 54 named indications.

That list covers almost every common use case for these devices in outpatient and rehabilitation settings. Knee osteoarthritis, carpal tunnel syndrome, plantar fasciitis, fibromyalgia, neck and back pain, wound healing, lymphedema, temporomandibular joint disorders — all of them are explicitly denied. So are stroke, traumatic brain injury, Parkinson's disease, Alzheimer's disease, and depression.

Dental pain, dentin hypersensitivity, periodontitis, recurrent aphthous stomatitis, and oral lichen planus are also on the non-covered list. If your dental billing team has been submitting laser claims for any of those conditions, stop. HCPCS code S8948 — the application of low-level laser therapy requiring constant provider attendance — is specifically listed as not covered for any indication in this policy. That's a flat denial code under this CPB.

CPT 97037 (low-level laser therapy, nonthermal and non-ablative) sits in a group the source policy labels with a truncated description that suggests no special coverage applies for high-power laser (class IV) therapy. The source text for that group is cut off in the available policy data, so verify the full group description in the original CPB before drawing firm conclusions about 97037's coverage pathway.

The real issue here isn't that Aetna is being unreasonable — these therapies genuinely lack strong clinical evidence for most indications. The issue is that many practices have been billing these services with an expectation of coverage that this policy clearly doesn't support. If you're seeing paid claims for 97037 on musculoskeletal conditions in Aetna's book of business, audit them. An overpayment recovery demand is worse than a denial.

Coverage Indications at a Glance

† CPT 0552T appears in the policy's "covered when selection criteria are met" group, but the same policy lists "low-level laser therapy using dynamic photonic and dynamic thermokinetic energies" as experimental, investigational, or unproven. This is a direct internal conflict in the policy. Do not bill 0552T without first confirming with Aetna how they're applying it. Your compliance officer should be part of that conversation.
