When is D2740 used?
The D2740 dental code applies to crowns made from porcelain or ceramic materials. This CDT code is utilized when a tooth needs complete coverage due to significant decay, breaks, or following endodontic treatment, with porcelain or ceramic chosen as the restoration material. D2740 is not appropriate for crowns constructed from different materials like all-metal or porcelain-fused-to-metal restorations, which have distinct coding requirements. Selecting the appropriate code helps ensure proper claim processing and reduces rejection rates.
D2740 Charting and Clinical Use
Proper record-keeping is crucial for successful payment under D2740. Patient records must clearly document the crown's necessity (such as broken cusps, large deteriorating fillings, or teeth treated with root canals), the chosen material, and include supporting X-rays or clinical photographs. Typical treatment situations include:
A back tooth with a broken cusp and substantial structural loss, needing a porcelain crown for durability and appearance.
Front teeth with large, deteriorating composite fillings where complete ceramic crown coverage is recommended.
Teeth following root canal treatment where complete coverage with non-metal crowns is chosen for aesthetic purposes.
Documentation should always include before and after photographs, comprehensive treatment notes, and X-rays in patient files to justify the treatment's medical necessity.
Billing and Insurance Considerations
To optimize payment and reduce processing delays, implement these recommended practices when submitting D2740 claims:
Check benefits: Prior to treatment, verify patient insurance coverage for crowns, including waiting periods and material limitations.
Provide complete records: Include treatment notes, X-rays, and clinical images with your claim. Clearly explain why complete porcelain/ceramic crown coverage is medically necessary.
Write clear descriptions: Include brief explanations of clinical needs (such as "Tooth #14 shows cusp fracture with inadequate remaining structure for filling. Porcelain crown needed for strength and appearance.")
Review payment explanations: Check benefit statements for rejection reasons. When claims are denied, file appeals quickly with supplementary documentation or explanations.
Understand alternative codes: When different crown types are placed, use appropriate codes, including porcelain bonded to high noble metal crowns or complete cast high noble metal crowns.
How dental practices use D2740
Patient scenario: A 38-year-old individual arrives with a broken upper left first molar (tooth #14). The tooth contains a large, deteriorating composite filling and recently underwent endodontic therapy. Following discussion of treatment alternatives, the patient and dentist select a complete porcelain crown for maximum durability and aesthetics.
Processing procedures:
Confirm insurance coverage for porcelain crowns and review any waiting period requirements.
Record clinical observations, including fracture, filling deterioration, and root canal treatment, in patient documentation.
Capture and store pre-treatment X-rays and clinical photographs.
Process the claim using D2740, including all supporting materials and detailed explanation.
Monitor claim progress and address any information requests or appeals promptly.
These procedures help ensure prompt payment and minimize claim rejection risks for D2740.
Common Questions
What material restrictions apply when billing code D2740?
Code D2740 is specifically designated for crowns constructed entirely from porcelain or ceramic materials. This code cannot be used for crowns that contain any metal components, including porcelain-fused-to-metal (PFM) restorations, which require different billing codes. Improper use of D2740 for metal-containing crowns may lead to claim rejections or compliance audits.
Is code D2740 appropriate for both primary and permanent teeth?
Code D2740 is designed for use on permanent teeth only. When treating primary (deciduous) teeth, different codes should be utilized, such as D2930 for stainless steel crowns on primary teeth or D2934 for prefabricated esthetic crowns on primary teeth. Proper code selection must be based on both the tooth type and crown material.
How should dental practices handle insurance downgrades of D2740 claims?
When insurance carriers downgrade D2740 benefits to metal crown reimbursement levels, dental practices should promptly notify patients of the coverage limitation and resulting financial responsibility. Practices must document the downgrade thoroughly in patient records and provide transparent explanations in treatment plans and financial agreements regarding the patient's obligation to pay the difference between the porcelain/ceramic crown fee and the metal crown benefit allowance.
