This policy addresses coverage and medical necessity for low-level laser therapy (photobiomodulation) for Medicare Advantage and commercial members, specifying covered indication(s) and noncovered indications.
No material clinical or coverage changes in this revision.
Coverage Criteria
inv-01: Coverage — Prevention of Oral Mucositis — Covered when ALL of the following are met
Covered when ALL of the following are met
Evidence sufficient for meaningful improvement in net health outcome for prevention of oral mucositis.
inv-02: Coverage — Not Medically Necessary / Not Covered Indications — list of indications considered not covered
Not covered / Not medically necessary for the following indications
Evidence is insufficient to determine effects on health outcomes for these indications.
Benefits and coverage for low-level laser therapy (LLLT) may differ across employer groups and insurance contracts. Refer to the member’s specific Benefit Booklet, Evidence of Coverage, or Subscriber Agreement to confirm whether LLLT is a covered benefit or is excluded for the member’s plan. Contract terms supersede this policy for member-specific determinations.
The sections cited here are reference lists and literature citations and do not by themselves state explicit coverage exclusions or determinations. Use the policy’s coverage and not‑medically‑necessary sections for formal coverage decisions and consult plan documents for contract‑specific exclusions.
If a service is determined to be not medically necessary or is a non‑covered benefit under the member’s contract, it is excluded from coverage unless the member was informed in advance and provided written agreement to self‑pay. Providers should follow participation and billing agreements and verify member benefits prior to rendering services.
Except for the specific covered indication for prevention of oral mucositis, LLLT is considered not medically necessary for all other indications because the evidence is insufficient to determine meaningful benefit. Examples of indications regarded as not medically necessary include, but are not limited to: carpal tunnel syndrome, neck pain, subacromial impingement, adhesive capsulitis, temporomandibular joint pain, low back pain, osteoarthritic knee pain, heel pain (eg, Achilles tendinopathy, plantar fasciitis), rheumatoid arthritis, Bell palsy, fibromyalgia, wound healing, and lymphedema.
The policy contains an extensive reference list of primary studies, systematic reviews, and clinical guidelines that informed the coverage determinations. These citations provide supporting evidence but do not on their own establish coverage; see the policy rationale and criteria for the official determinations.
Coverage and medical‑necessity determinations depend on the member’s subscriber or employer agreement and the specific contract. For member‑specific benefit information or questions about coverage status, contact the provider call center or review the applicable plan documents.

Provider Actions / Billing
Prior Authorization Status
Prior authorization is not applicable for this policy.
- Verify member-specific benefits and eligibility prior to scheduling services by referring to the applicable Benefit Booklet, Evidence of Coverage, or Subscriber Agreement; benefits may vary by group/contract (source chunk 6, 49).
- For member-specific determinations or to confirm benefit coverage, contact the provider call center (source chunk 49).
- Non-covered or not medically necessary indications (eg, indications other than prevention of oral mucositis) may result in claim denials; do not bill members for non-covered services unless informed written consent is obtained in advance (source chunks 4, 5, 49).
- When billing for low-level laser therapy (LLLT), submit the applicable procedure codes with relevant ICD-10-CM diagnosis codes: 0552T, 97037, S8948 filed with ICD-10-CM diagnoses C00-D49 or K12.30-K12.39 as appropriate (source chunks 14, 15).
- There are no additional documentation requirements specified in the policy reference sections beyond usual medical record and claim documentation; maintain clinical records supporting medical necessity when applicable (source chunk 18).
- Prior authorization / benefit determination for LLLT should be handled on a member-specific basis via the provider call center when needed (source chunk 49).
Background
Low‑level laser therapy (also called photobiomodulation) uses red‑beam or near‑infrared light with wavelengths in the approximate range of 600–1000 nm and low power outputs (typically on the order of milliwatts). The treatment is nonthermal and non‑ablative, produces no burning sensation when applied appropriately, and is proposed to act via photobiostimulation of cellular repair and modulation of immune, lymphatic, and vascular processes. Devices are intended to deliver low‑intensity light to tissues to reduce pain, promote healing, or prevent conditions such as oral mucositis.

OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
