    This policy establishes clinical criteria for determining the medical necessity and clinical appropriateness of periodontal maintenance, including eligibility, clinical quality, documentation, and benefit limitations. It applies to providers submitting periodontal maintenance for benefit payment under a member's dental plan.

    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.

    Medical Necessity and Coverage Criteria

    Initial clinical eligibility and delivery requirements

    Periodontal maintenance may be considered medically necessary and clinically appropriate when all of the following conditions are met:

    Required clinical indication and delivery conditions

    • Qualifying periodontal disease history: The patient has a diagnosis of periodontal disease involving detectable loss of bone and/or attachment, and active surgical or nonsurgical periodontal therapy was performed before periodontal maintenance began.
    • Licensed dentist supervision: Periodontal maintenance appointments are supervised by a licensed dentist.
    • Adequate appointment time: The scheduled time is adequate to effectively remove supragingival and subgingival plaque and calculus and perform any required site-specific scaling and root planing on the patient's existing dentition.

    Maintenance interval and reassessment

    The maintenance interval should be individualized for the patient. Typical treated patients may benefit from appointments at least four times per year.

    Individualized maintenance planning: Determine the maintenance interval based on the patient's systemic health conditions, periodontal condition, risk status, compliance factors, and prognosis.

    Evidence suggests that typical patients with a history of surgical or nonsurgical periodontal treatment may benefit from periodontal maintenance appointments at least four times per year to reduce the risk of progressive disease.

    Management of recurrent or progressive disease

    When new development, recurrence, or progression of periodontal disease is identified during maintenance, all of the following response requirements apply:

    Disease recurrence or progression response

    • Consider additional diagnostic procedures and periodontal therapy when new development, recurrence, or progression of periodontal disease is identified during the periodontal maintenance procedure.

      Periodontal maintenance should not be used as monotherapy when active surgical or nonsurgical periodontal therapy is required; maintenance may be modified or suspended while additional active treatment is provided.

    Appendix benefit limitations

    Benefit payment is subject to all of the following Appendix A limitations:

    • Prior active periodontal procedure: Scaling or root planing was performed within the previous 24 months.within the previous 24 months
    • Timing separation: The periodontal maintenance procedure is not performed in conjunction with prophylaxis or within 30 days of scaling and root planing.not in conjunction with prophylaxis; not within 30 days of scaling and root planing
    • Frequency limit: Periodontal maintenance is covered no more than once every 365 days.once every 365 days

    Periodontal maintenance may be considered for benefit payment when the patient has a documented diagnosis of periodontal disease involving detectable loss of bone and/or attachment and has received active surgical or nonsurgical periodontal therapy before maintenance began.

    Periodontal maintenance is not appropriate as monotherapy when new, recurrent, or progressive periodontal disease requires active surgical or nonsurgical periodontal therapy. Additional active treatment should be addressed instead of relying on maintenance alone.

    No payment is made for periodontal maintenance performed in conjunction with prophylaxis or within 30 days of scaling and root planing.

    Maintenance may be determined not medically necessary or not clinically appropriate when there is no qualifying history of periodontal disease with detectable loss of bone and/or attachment treated with active periodontal therapy, when appointments are not supervised by a dentist, or when scheduled time is definitively inadequate to remove supragingival and subgingival plaque and calculus and perform required site-specific scaling and root planing.

    Documentation and Provider Requirements

    Documentation Required

    Submit Records for Clinical Review

    When Delta Dental of Ohio reviews periodontal maintenance for medical necessity or clinical appropriateness, the treating practitioner may be required to submit supporting information from the patient’s dental record. If the requested information cannot be provided, benefit payment may be disapproved; Delta Dental may also request other relevant clinical information needed to make a coverage decision.

    • Submit the patient’s dental record and any other relevant clinical information requested for review.
    • Ensure the record supports both medical necessity and clinical appropriateness for the procedure.
    Documentation Required

    Clinical and Radiographic Records

    Base periodontal maintenance on a thorough clinical and radiographic examination and document periodontal disease involving detectable loss of bone and/or attachment, with active surgical or nonsurgical periodontal therapy completed before maintenance began.

    • Document six-point periodontal pocket depth charting for the teeth undergoing maintenance.

    Clinical Background

    Periodontal maintenance is supportive periodontal therapy provided after active surgical or nonsurgical treatment for periodontal disease. It is intended to limit disease progression, reduce the risk of tooth loss, and identify new or continuing periodontal breakdown. The service includes periodontal evaluation, risk assessment, supragingival and subgingival plaque and calculus removal, site-specific scaling and root planing when indicated, and polishing. The maintenance interval is individualized according to systemic health, periodontal condition, risk status, compliance, and prognosis.

    4. Documentation Required

    Diagnosis, Prognosis, and Risk-Factor Notes

    Include brief remarks that support the treatment decision and explain the patient’s periodontal status, expected outcome, and need for the selected maintenance interval.

    • State the periodontal diagnosis using the American Academy of Periodontology Classification of Periodontal and Peri-Implant Diseases and Conditions.
    • Document the periodontal treatment plan and prognosis.
    • Identify relevant risk factors for recurrence or progression of periodontal disease, including factors requiring an atypical periodontal-maintenance interval.
    • Document the patient’s response to prior treatment when relevant to the diagnosis, prognosis, or ongoing plan of care.
    Denial Risk

    Clinical Indication, Supervision, and Appointment Adequacy

    Periodontal maintenance may be denied as not medically necessary or clinically appropriate when the clinical indication, dentist supervision, or appointment adequacy is deficient.

    • Do not submit maintenance when there is no history of periodontal disease with detectable loss of bone and/or attachment treated by active surgical or nonsurgical periodontal therapy, such as gingival inflammation without attachment loss.
    • Do not use periodontal maintenance as monotherapy when new, recurrent, or progressive periodontal disease requires active surgical or nonsurgical periodontal therapy.
    • Ensure a dentist supervises periodontal maintenance appointments.
    • Schedule adequate time to perform supragingival and subgingival plaque and calculus removal and any required site-specific scaling and root planing on the existing dentition.
