Simplify your dental coding with CDT companion
When is D0277 used?
The D0277 dental code applies specifically to vertical bitewing X-ray images. These differ from standard horizontal bitewings by providing enhanced visualization of alveolar bone structures, making them particularly useful for tracking periodontal disease development. This code is appropriate when taking a complete series of seven to eight vertical bitewing radiographs to evaluate bone levels between teeth and identify decay in patients experiencing moderate to advanced periodontal issues. Reserve this code for cases where clinical examination or patient history suggests significant bone deterioration, rather than for standard cavity screening in patients with healthy gums.
Record Keeping and Clinical Applications
Proper record keeping is essential when submitting claims for D0277. Patient records must clearly document the periodontal condition or risk factors that warrant vertical bitewing radiographs. Comprehensive clinical notes should describe gum pocket measurements, extent of bone deterioration, or prior periodontal interventions. Supporting materials like periodontal measurements and oral photographs can reinforce your billing submission. Typical applications for D0277 include:
Monitoring patients with established periodontal disease history
Initial assessment of new patients showing widespread bone deterioration
Follow-up evaluations after periodontal treatment procedures
Confirm that the actual number of radiographs corresponds to the code requirements and that all images meet diagnostic standards.
Reimbursement Strategy Guidelines
Insurance companies often impose strict timing restrictions and documentation standards for D0277 claims. Prior to claim submission, confirm patient benefits and allowable frequency for bitewing X-rays. When D0277 claims are rejected for frequency reasons, carefully review the benefits explanation statement and consider filing an appeal with comprehensive clinical evidence. Recommended approaches include:
Obtaining prior approval when feasible, particularly for patients with documented periodontal conditions
Including clinical documentation, periodontal measurements, and radiographic images with claims
Applying the appropriate CDT code—avoid using D0277 in place of horizontal bitewing codes (D0272 or D0274)
Monitoring claim progress through your billing management system and addressing rejections quickly
Maintaining detailed records and clear communication helps improve payment success rates and reduces processing delays.
Clinical Example for D0277 Implementation
A 52-year-old patient with documented chronic gum disease arrives for routine periodontal care. During examination, the dental hygienist records pocket depths ranging from 5-7mm along with noticeable bone deterioration. The treating dentist requests a complete vertical bitewing series to assess current bone status and track disease changes over time. Detailed clinical records document the patient's condition, treatment history, and clinical justification for vertical radiographs. The insurance claim includes D0277 with supporting periodontal charts and clinical photographs. Although initially rejected for timing restrictions, a successful appeal with complete documentation results in full claim approval and payment.
This scenario demonstrates how detailed documentation and persistent follow-up are critical for successful D0277 billing outcomes.
FAQ
What makes D0277 different from standard bitewing codes D0272 and D0274?
D0277 represents a comprehensive series of 7-8 vertical bitewing radiographs that offer superior visualization of alveolar bone levels compared to conventional horizontal bitewings. In contrast, D0272 and D0274 cover 2 or 4 horizontal bitewing images respectively, which are generally adequate for routine cavity detection. D0277 is the preferred choice when treating patients with periodontal disease or when detailed bone level assessment is clinically necessary.
What safety precautions should be considered when performing 7-8 vertical bitewing radiographs with D0277?
Although dental X-rays are generally safe, practitioners must follow ALARA (As Low As Reasonably Achievable) principles to keep radiation exposure minimal. Take only the clinically necessary number of images, utilize appropriate protective shielding, and maintain equipment in proper working condition. D0277 should be reserved for cases where the clinical situation truly warrants comprehensive periodontal or diagnostic evaluation.
How should a dental practice handle insurance claim denials for D0277?
When facing a D0277 claim denial, first examine the Explanation of Benefits (EOB) to identify the specific denial reason. Typical causes include inadequate documentation or frequency restriction violations. Compile comprehensive supporting materials including detailed clinical notes, current periodontal charting, and radiographic evidence, then file an appeal with the insurance company. Prompt follow-up combined with clear documentation of medical necessity significantly increases approval likelihood.
