Coverage Criteria

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 criteria and restrictions

When covered by a specific group contract, indications for biologic materials must be documented as follows:

Documentation requirements: ALL of the following must be documented: diagnostic pretreatment periapical radiographs current within 12 months; current dated 6-point periodontal charting indicating minimum 5 mm pocket depths; a letter of rationale explaining necessity and the type of biologic material used may be requested (examples: PRP, Emdogain, rhBMP, Gem-21S).

Usage exclusions: Use of biological materials may not be considered when used in conjunction with soft tissue grafting, bone grafts, guided tissue regeneration, ridge augmentation, periradicular surgery, placed within extraction sites, or when utilized with other regenerative materials regardless of specific group plan coverage.

This limitation applies regardless of specific group plan coverage.

The policy specifies that the use of biological materials will not be considered when they are used in conjunction with certain procedures or settings. Specifically, these materials are not considered when used with soft tissue grafting, bone grafts, guided tissue regeneration, ridge augmentation, periradicular surgery, placed within extraction sites, or when used with other regenerative materials, regardless of specific group plan coverage.

Services involving biologic materials that do not meet generally accepted standards of dental practice or the member's specific group contract requirements may be considered not medically/dentally necessary and may be denied. The plan reviews these services against accepted standards of care, applicable contract language, and federal/state law, which take precedence over this policy.

Provider Documentation & Operational Actions

Documentation Required

Documentation Required for Coverage

When coverage is requested, include complete documentation to support medical/dental necessity. Required documentation may include: diagnostic-quality pretreatment periapical radiographs (properly oriented, identified, and dated within 12 months), current 6‑point periodontal charting (dated) showing ≥5 mm pocket depths, and a letter of rationale explaining the necessity of the regeneration procedure and the specific biologic material to be used (for example PRP, Emdogain, rhBMP, Gem-21S).

Pretreatment radiographs: diagnostic quality, properly oriented, identified and dated (within 12 months).
Periodontal charting: current, dated 6-point charting per AAP/ADA showing minimum 5 mm pocket depths.
Letter of rationale: explain clinical necessity and specify the biologic material (e.g., PRP, Emdogain, rhBMP, Gem-21S).

Prior Authorization

Actionable Provider Requirements

Ensure documentation is submitted with the claim or prior authorization request as applicable. Failure to provide the required records may result in denial of benefits or delay while the plan requests additional information.

Attach radiographs and periodontal charting to the prior authorization or claims submission when requested.
Include the letter of rationale describing why regeneration is necessary and why the chosen biologic material is indicated.

Documentation Required

Pretreatment Radiograph & Periodontal Charting Specifications

Radiographs must be periapical images of diagnostic quality, properly oriented, identified and dated. Periodontal charting must be current and include a full 6‑point chart as described by the AAP and ADA; documentation must clearly show the location(s) and probe depths demonstrating the clinical indication (minimum 5 mm).

Radiograph specifics: periapical, diagnostic quality, orientation, ID, and date (<= 12 months).
Periodontal charting specifics: full 6‑point charting per AAP/ADA, dated, showing >=5 mm pocket depths.

Denial Risk

Denial Risk / Contractual Compliance

Services that do not meet the plan contract terms or generally accepted standards of dental practice may be denied. Federal or state law and specific group contract provisions take precedence; verify coverage via the member's contract and contact customer service if review is required.

Noncompliant or incomplete documentation may result in claim denial.
Group contract terms and state/federal law override policy guidance — confirm benefit applicability before treatment.

Background

Adjunctive regenerative therapy using biologic materials in dentistry is intended to regenerate damaged soft and osseous tissues rather than rely solely on grafts. These biologic substitutes are used to restore, maintain, or improve tissue function and can be applied to treat periodontal defects of natural teeth and, more recently, peri‑implant defects. When covered by a specific group contract, use of these materials requires documentation—diagnostic pretreatment periapical radiographs dated within 12 months, current 6‑point periodontal charting showing a minimum 5 mm pocket depth, and a letter of rationale describing the necessity and type of material.
