POLICY UPDATE CHANGES

New medical policy describing investigational indications for HILT became effective 12/1/2024.

HILT for treatment of Bell's palsy is considered investigational.

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Coverage Determinations

Coverage determination

Policy coverage and investigational determinations

Overall stance: HILT for chronic musculoskeletal pain: the evidence is insufficient to determine improvement in net health outcome due to methodological limitations, heterogeneity in HILT parameters and cointerventions, and lack of established practice guidelines; HILT for Bell's palsy: considered investigational given limited evidence and the possibility of spontaneous recovery.

Based on randomized clinical trials and systematic reviews showing inconsistent or low‑confidence benefit.

Outpatient high-intensity laser therapy (HILT) is not a covered service for the following product lines: Commercial PPO and Indemnity, Medicare HMO BlueSM, and Medicare PPO BlueSM. Providers should refer to member contract benefits for individual coverage determinations and note that prior authorization requirements described elsewhere in this policy apply when the procedure is performed inpatient.

For chronic musculoskeletal disorders, the evidence base includes randomized clinical trials and systematic reviews; however, methodological limitations of the trials, heterogeneity in HILT device parameters and cointerventions, and variations in patient characteristics reduce confidence in the findings. As a result, the evidence is insufficient to determine that HILT leads to an improvement in net health outcome for chronic musculoskeletal pain.

Provider Requirements and Billing Guidance

Prior Authorization

Precertification required for inpatient; outpatient noncovered in specified products

Precertification/prior authorization is required when HILT is performed inpatient; outpatient HILT is described as not a covered service for certain product lines.

Precertification/prior authorization IS REQUIRED for all products if the procedure is performed inpatient.
Outpatient HILT is not a covered service for Commercial PPO and Indemnity, Medicare HMO BlueSM, and Medicare PPO BlueSM.

Step Therapy

Step therapy: none specified

No step therapy requirements are specified in this policy for HILT.

Background

High-intensity laser therapy (HILT) refers to Class IV therapeutic non-surgical laser devices with a power output of >500 mW that transmit infrared energy capable of reaching deeper musculoskeletal tissues. HILT is proposed to provide temporary relief of muscle spasm and minor muscle or joint pain through mechanisms such as photobiomodulation, photothermal effects, and neural analgesic effects, although the precise mechanism of clinical benefit is not clearly established.

Definitions

High‑Intensity Laser Therapy (HILT) — definition and device class/power

DefinitionHigh‑Intensity Laser Therapy (HILT) is a Class IV therapeutic non‑surgical laser device intended to deliver infrared energy to provide temporary relief of muscle spasms and minor muscle/joint pain.

Device classClass IV therapeutic non‑surgical laser device

Power characteristic>500 mW (capable of transmitting energy beyond the skin to deep musculoskeletal tissues)

Conservative Treatment Requirements

Frequency Limits

HILT — frequency limits (policy placeholder)

Frequency limits — policy statusNo specific frequency limits stated in policy; frequency limits section contains no numeric limits.

Outpatient coverage noteOutpatient HILT is described as not a covered service for Commercial PPO and Indemnity, Medicare HMO BlueSM, and Medicare PPO BlueSM.

Prior authorization implicationPrecertification/prior authorization is required when the procedure is performed inpatient; lack of stated frequency limits does not change authorization requirements.

Imaging Requirements

Note

HILT device threshold (>500 mW) and no specific imaging requirement stated

Policy defines HILT as a Class IV therapeutic non-surgical laser device with power output >500 mW; imaging requirements are not specified in the policy.

HILT described as a Class IV device with power output >500 mW capable of transmitting energy to deep musculoskeletal tissues.
The policy does not list specific imaging requirements for HILT.

Not Covered Services

Outpatient high-intensity laser therapy (HILT) is explicitly specified as not covered for Commercial PPO and Indemnity, Medicare HMO BlueSM, and Medicare PPO BlueSM members in the outpatient setting. Providers must confirm member-specific benefits and are reminded that there is no CPT code for this procedure and that standard industry coding and reporting practices should be followed when documenting services.
