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.

Services that do not meet generally accepted standards of dental practice or that lack a prior history of definitive periodontal treatment may be considered not medically necessary or not covered. The plan reviews periodontal maintenance to ensure services meet contractual requirements for generally accepted standards and appropriate clinical indications.

Coverage may be denied when requested services are inconsistent with contract requirements or are concluded not to meet accepted standards of care.

Provider Actions, Documentation & Prior Authorization

Documentation Required

Required clinical documentation

For periodontal maintenance, the following should be documented: history of prior definitive periodontal therapy including dates and specific treatments rendered; evidence of continuous care not exceeding 12 months; and post‑initial therapy evaluations and treatment planning recommendations following completion of periodontal maintenance. A periodontal maintenance procedure is not appropriate when there is no history of periodontal disease requiring definitive periodontal treatment.

History of prior definitive periodontal therapy with dates and specific treatments rendered
Evidence of continuous periodontal care (intervals not exceeding 12 months)
Post‑initial therapy evaluations and treatment planning recommendations are integral to the procedure
Periodontal maintenance is inappropriate without prior definitive periodontal treatment

Prior Authorization

Locally administered chemotherapeutic agents — prior authorization / medical necessity

Use of locally administered chemotherapeutic agents (LACA) as part of periodontal maintenance requires a Letter of Medical Necessity to support the medical necessity of the agent for the member.

LACA require a Letter of Medical Necessity

Denial Risk

Coverage may be denied if not generally accepted

Coverage may be denied if the service provided is not consistent with generally accepted standards of dental care or when documentation does not support a history of periodontal disease requiring definitive treatment.

Services must meet generally accepted standards of dental practice in type, frequency and extent
Lack of documentation of prior definitive periodontal therapy or ongoing need may result in denial

Billing Rule

Provider action / billing note

Document actionable items for billing and claims: include dates and descriptions of prior periodontal therapy, attach the Letter of Medical Necessity when LACA are used, and ensure records show ongoing periodontal maintenance within 12‑month intervals to support coverage.

Attach Letter of Medical Necessity for LACA to the claim
Include dates and specifics of prior definitive periodontal treatment in the chart and claim documentation
Maintain records showing continuous periodontal maintenance (≤12 months between visits)

Background

Periodontal maintenance is a lifelong nonsurgical therapeutic phase provided after definitive periodontal treatment. Its purpose is to remove etiologic factors (such as plaque, biofilm and adherent calculus), instrument crown and root surfaces, and monitor periodontal conditions to maintain the periodontal health achieved during active therapy. Periodontal maintenance is therapeutic rather than prophylactic and is intended to continue for the life of the dentition or any implant placement.

Definitions

Periodontal maintenance definition — nonsurgical treatment following therapeutic periodontal treatment

DefinitionPeriodontal maintenance is a nonsurgical therapeutic phase following definitive periodontal (active) therapy that continues for the life of the dentition or any implant placement and provides ongoing treatment and monitoring for patients with a history of and ongoing periodontal disease.

PurposeRemove etiologic factors (plaque, biofilm, adherent calculus) and diseased cementum, and maintain periodontal health achieved after active therapy.

ComponentsInstrumentation of tooth crown and root structures, including hand instrumentation, to remove deposits and microbial irritants and to monitor periodontal conditions.

ScopeConsidered therapeutic rather than prophylactic and constitutes continuing care for patients diagnosed with periodontal disease.

GoalReduce or eliminate causative factors responsible for initiating host inflammatory responses to maintain periodontal status attained after active periodontal therapy.

Generally accepted standards — definition for dental purposes

DefinitionFor dental purposes, 'generally accepted standards of dental practice' are dental services that a dentist, exercising prudent clinical judgment, provides to evaluate, diagnose, or treat a dental injury or disease or its symptoms in accordance with accepted standards in terms of type, frequency, and extent.

BasisStandards reflect care that is considered effective and aligns with generally accepted standards of dental practice for evaluating and treating periodontal disease.

ApplicationUsed to determine appropriateness of periodontal maintenance and other dental services relative to documented history and clinical need.

Clinical expectationServices should be consistent with prudent clinical judgment and accepted professional practice for the type, frequency, and extent of care provided.
