D4910
Pronunciation: D-four-nine-one-oh
The CDT procedure code for periodontal maintenance, a recall appointment for patients who have completed active periodontal therapy.
Full Definition
D4910 denotes 'periodontal maintenance', the supportive care visit provided at intervals of two to four months for patients who have completed active periodontal treatment such as scaling and root planing. It is therapeutically and procedurally distinct from D1110 (adult prophylaxis), which is a preventive service for periodontally healthy patients. Using D4910 in documentation signals that the patient has a history of periodontal disease and requires enhanced monitoring. Editors reviewing insurance correspondence, treatment plan narratives, or clinical audit data must verify that D4910 is not substituted for D1110 or vice versa, as such errors can result in insurance fraud implications or claim denial. The code is rendered identically to other CDT codes: capital D followed by four digits.
Usage
Usage note: D4910 should never be used interchangeably with D1110. Confirm the patient's periodontal history before assigning or accepting this code in editorial contexts.
