CDT-2024 D4910


This procedure is instituted following periodontal therapy and continues at varying intervals, determined by the clinical evaluation of the dentist, for the life of the dentition or any implant replacements. It includes removal of the bacterial plaque and calculus from supragingival and subgingival regions, site specific scaling and root planing where indicated, and polishing the teeth. If new or recurring periodontal disease appears, additional diagnostic and treatment procedures must be considered.

    1. Ongoing periodontal maintenance (D4910) does not include the periodic oral evaluation (D0120) or comprehensive periodontal evaluation (D0180). The periodic oral evaluation (D0120) or D0180 is submitted as a separate procedure on the same date of service. The oral evaluation (D0120 or D0180) is generally provided twice per year, and is subject to the typical “one evaluation per six months” or “two evaluations per year” limitation. For a comprehensive periodontal evaluation of an established periodontal patient provided on a periodic basis consider reporting D0180. Note: The reimbursement for D0180 might be re-mapped as D0120 and may create patient confusion. If the more extensive and time consuming D0180 is performed, report what you do.
    2. Some offices report one D0180 and one D0120 per year for periodontal recall patients. Some offices have two consistent, but different, fee levels for D0180, depending on whether the procedure is provided for the new (entering the practice) or established (recall) D4910 patient. For instance, the D0180 fee for recall might be $12-$15 higher than the D0120 fee. See D0180 for details.
