Coverage Criteria — When Services Are Covered

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.

Indications when covered by group contract

Covered only when ALL of the following documented conditions are met per group contract

Documentation and clinical criteria: 1) Pretreatment periapical radiographic images that are of diagnostic quality, properly oriented, identified, and dated within 12 months; 2) Current, dated 6-point periodontal charting (per AAP/ADA) indicating minimum 5 mm pocket depths; 3) A letter of rationale explaining the necessity of the regeneration procedure and identifying the type of biologic material to be used (e.g., PRP, Emdogain, rhBMP, Gem-21S).Radiograph within 12 months; pocket depth >= 5 mm

Documentation must be provided when coverage is subject to specific group contract.

The use of biologic materials will not be considered for coverage when used in conjunction with other procedures or regenerative materials. Specifically, biologic materials are excluded when used 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.

Coding and Documentation Thresholds

CDT (example) codesCPT

D3431	Biologic materials to aid in soft and osseous tissue regeneration in conjunction with periradicular surgery
D4265	Biological material to aid in soft and osseous tissue regeneration, per site

Radiograph recency — within 12 months

RequirementPretreatment periapical radiographic images of diagnostic quality that are properly oriented, identified, and dated within 12 months

PurposeDemonstrates baseline periapical status to support medical necessity for biologic materials

Documentation noteRadiographs must be current (dated within 12 months) as specified by the group contract documentation requirements

Periodontal pocket depth — >= 5 mm

Minimum pocket depth>= 5 mm (documented on current, dated 6‑point periodontal charting)

Charting standard6‑point periodontal charting as described by the American Academy of Periodontology (AAP) and American Dental Association (ADA)

PurposeConfirms presence of periodontal defect severity that may justify use of biologic regenerative materials

Provider Requirements, Documentation, and Denial Risk

Prior Authorization

Prior authorization / contract verification

When covered by a specific group contract, providers must verify prior authorization and contract benefit requirements before performing biologic materials procedures. The plan may require that indications and supporting documentation be submitted for review; listed CDT/diagnosis codes are informational and do not guarantee coverage.

Verify member contract benefits and prior authorization requirements before scheduling procedures.
Submit indications and required documentation when requested by the plan to determine coverage.
CDT/ICD-10 codes listed in the policy are informational only — coverage depends on the member's contract.

Documentation Required

Required documentation

Required documentation must be maintained in the patient record and made available to the plan upon request. Documentation should clearly support the clinical need for use of biologic materials.

Pretreatment periapical radiographic images of diagnostic quality, properly oriented, identified, and dated within 12 months.
Current, dated 6‑point periodontal charting (as described by AAP/ADA) showing minimum 5 mm pocket depths when applicable.
A letter of rationale explaining the necessity of the regeneration procedure and the specific material to be used (for example: PRP, Emdogain, rhBMP, Gem-21S).

Denial Risk

Documentation-related denials

Claims may be denied if required documentation is missing or incomplete. Providers should ensure records meet all documentation standards prior to submission to reduce denial risk.

Lack of diagnostic-quality periapical radiographs within the prior 12 months may result in denial.
Absence of current 6‑point periodontal charting showing the indicated pocket depths may lead to denial.
Failure to provide a letter of rationale or documentation supporting clinical necessity when requested may result in non‑payment.

Denial Risk

Excluded adjunct uses

Biological materials are not considered when used as adjuncts with certain procedures; use in these contexts may be excluded from coverage under some group contracts.

Use of biological materials in conjunction with soft tissue grafting, bone grafts, guided tissue regeneration, ridge augmentation, or periradicular surgery is generally not considered.
Use within extraction sites or when utilized with other regenerative materials is typically excluded.
If a group contract has specific language allowing coverage in these adjunctive uses, the provider must supply the contract-required documentation and prior authorization evidence.

Background

Tissue engineering and regenerative dentistry employ biological substitutes to restore or improve soft and osseous tissue function in periodontal defects. Examples of adjunctive regenerative products include platelet-rich plasma (PRP), enamel matrix derivatives (e.g., Emdogain), recombinant human bone morphogenetic proteins (rhBMP), and commercial matrices such as Gem-21S.

When coverage is determined by a specific group contract, documentation is required to support the medical necessity of these procedures: a pretreatment periapical radiograph of diagnostic quality dated within 12 months, current 6-point periodontal charting demonstrating a minimum pocket depth of 5 mm, and a letter of rationale describing the need for the regeneration procedure and the type of biologic material to be used.
