Coverage criteria for occlusal (bite) guards

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.

Occlusal guard coverage criteria: 1) The appliance is intended to protect natural teeth or restorations from bruxism or clenching-related wear or fracture; 2) The treatment is consistent with generally accepted standards of dental practice (based on peer-reviewed evidence, specialty recommendations, and practicing dentists' views); 3) A narrative with rationale for treatment is provided; 4) Use is not for treatment of temporomandibular disorders, athletic mouth protection, orthodontic tooth movement, treatment of obstructive sleep apnea, tooth whitening, fluoride delivery, or periodontal medicament delivery.

Partial arch occlusal guards may not be covered depending on contract.

Occlusal guards are not indicated (and excluded) for treatment of temporomandibular disorders or myofascial pain dysfunction. They are also not indicated for use as an athletic mouth guard, as an appliance intended for orthodontic tooth movement, for treatment of obstructive sleep apnea, or for tooth whitening, fluoride delivery, or delivery of periodontal medicaments. Additionally, partial arch occlusal guards may not be covered depending on the member's contract.

Note

Coverage determined by member contract

Coverage is determined by the member's contract. Coding and code lists provided are informational only; inclusion here does not guarantee member coverage or provider reimbursement. Always verify benefits under the member's contract at the time of service.

See member contract for coverage determinations
Coding is informational only — does not imply coverage or reimbursement

Denial Risk

Linked-service denial risk

If a service is performed in conjunction with or in preparation for a non‑covered or denied service, all related services are also not covered or may be denied.

Linked services may be denied when associated primary service is not covered

Documentation Required

Narrative rationale required

Occlusal guard services require a narrative rationale documenting the clinical need for the appliance. The narrative should explain the diagnosis, symptoms (e.g., bruxism, tooth wear, sensitivity), treatment goals, and why an occlusal guard is appropriate for this member. Partial‑arch occlusal guards may be contract‑dependent and not covered; include justification if billing partial‑arch appliances.

Narrative must state clinical indication and rationale for occlusal guard
Document if occlusal guard is full vs partial arch and clinical justification

Billing Rule

Coding (informational)

Coding for occlusal guards and related procedures is provided for informational purposes only. Refer to the member contract to determine coverage. Common CDT codes include occlusal orthotic devices, appliance fabrication, adjustments, relines, and related diagnostic codes — see the CDT code set for full details.

Examples of relevant CDT codes: D7880, D7881, D9944, D9945, D9946, D9942, D9943, D9953, D0320, D0330, D0470, D9130

Background and purpose

Occlusal guards are removable appliances intended to protect natural teeth and restorations from wear or fracture caused by bruxism or clenching. They may be fabricated in-office or by a laboratory from rigid or semi-rigid materials and are used to minimize tooth sensitivity related to clenching or bruxism, to protect teeth when opposing dentition (for example, porcelain or ceramic restorations) could cause enamel wear or damage, and, when appropriate, to relieve occlusal stress following periodontal therapy. A narrative with rationale for treatment is required, and partial arch occlusal guards may not be covered depending on the member contract.

Coverage notePartial‑arch occlusal guards may not be covered depending on the member contract.

inv-11: Dental review / generally accepted standards — Definition of dental review as services consistent with generally accepted standards of dental practice.

TermDental review / generally accepted standards

DefinitionDental review: services a dentist provides, exercising prudent clinical judgment, to evaluate, diagnose, or treat a dental injury or disease or its symptoms that are in accordance with generally accepted standards of dental practice, appropriate in type/frequency/extent, effective for the patient, not primarily for convenience, and not cosmetic.
