What is Dental Code D2750?
D2750 describes a full crown restoration using porcelain fused to high noble metal. This procedure involves placing a permanent crown that combines a high noble metal substructure with a porcelain exterior. The restoration delivers both strength and aesthetics for damaged or weakened teeth.
The code applies when placing a crown made with a metal base containing at least 60% noble metal content by weight, with at least 40% gold content. The porcelain layer covers the metal framework, creating a natural appearance. This code encompasses all steps from preparation through final cementation of the permanent crown.
Common Terminology
Understanding the language around D2750 helps you select the correct code:
High noble metal: An alloy containing at least 60% noble metal by weight, with at least 40% gold, delivering superior biocompatibility and strength
Porcelain fused to metal (PFM): A crown type combining a metal substructure with a porcelain exterior layer that mimics natural tooth appearance
Crown preparation: The process of reducing tooth structure to create space for the crown restoration and establish proper fit
Final cementation: The permanent bonding of the crown to the prepared tooth using dental cement
Metal substructure: The internal framework of the crown that delivers structural support and retention
When is D2750 Used?
This code applies when you're restoring a tooth with a porcelain fused to high noble metal crown. The tooth must need full coverage, and the material specifications must match the high noble metal criteria. You'll select this code based on both clinical necessity and material composition.
Common Clinical Scenarios
You'll reach for D2750 in several situations:
Teeth with extensive decay that cannot be restored with fillings or inlays, needing full-coverage protection
Previously root-canal-treated teeth that need structural reinforcement to prevent fracture
Severely worn teeth from bruxism or erosion that need height restoration and protection
Fractured teeth with damage extending below the gum line or affecting multiple surfaces
Teeth serving as abutments for fixed bridges that need crown coverage for support
Aesthetic improvements in anterior regions where patients want both strength and natural appearance
When D2750 is NOT Appropriate
Certain situations call for different codes:
All-porcelain or ceramic crowns without metal substructures should use D2740 instead
Crowns using predominantly base metal alloys fall under D2752, not D2750
Noble metal crowns that don't meet the 40% gold requirement use D2751
Temporary or provisional crowns call for D2799 for interim coverage
Three-quarter crowns or partial coverage restorations need codes in the D2510-2664 range
Crown repairs or recementations use different codes in the D2910-2920 series
Billing and Insurance Considerations
Proper billing for D2750 demands detailed documentation and accurate material specification. Insurance companies scrutinize crown claims because they represent high-value procedures. Clear records and proper coding prevent payment delays and reduce audit risk.
Documentation Requirements
Your clinical notes must establish clear support for using this code:
Detailed examination findings showing why the tooth cannot be restored with a more conservative treatment
Pre-operative photographs documenting the extent of damage, decay, or existing restoration failure
Written treatment plan explaining why full-coverage restoration was selected over other options
Tooth-specific notation identifying which tooth received the D2750 crown
Laboratory prescription confirming the crown was fabricated with high noble metal meeting the code criteria
Shade selection and aesthetic considerations documented for anterior restorations
Radiographic documentation strengthens your claim:
Pre-operative radiographs showing the extent of decay, existing restorations, or structural damage
Images demonstrating adequate tooth structure remaining to support crown retention
Post-operative radiographs confirming proper crown margins and fit
Periapical films showing root canal treatment if applicable to the tooth being crowned
Insurance Coverage
Coverage for D2750 fluctuates across plans and hinges on several factors:
Most dental insurance plans cover crowns at 50-80% after deductibles when medically necessary
Many plans impose waiting periods of six to twelve months for major restorative work on new policies
Frequency limitations typically allow one crown per tooth every five to seven years
Some insurers demand pre-authorization with supporting documentation before approving crown treatment
Alternative benefit clauses may downgrade payment to a base metal or standard crown regardless of materials used
Coverage often excludes crowns placed primarily for cosmetic reasons without documented structural necessity
Common Billing Mistakes
Avoid these errors to minimize claim denials:
Billing D2750 when the crown uses base metal or doesn't meet high noble metal specifications, creating incorrect material coding
Submitting claims without adequate narrative explaining why the tooth demanded full-coverage restoration
Failing to obtain pre-authorization when the patient's plan mandates it, resulting in automatic denials
Billing D2750 for crown replacements within the insurance frequency limitation period without documenting the failure reason
Using incorrect tooth numbering or billing multiple crowns with unclear differentiation between procedure dates
Not documenting the laboratory work authorization showing high noble metal specifications
Common Questions
How often can D2750 be billed for the same tooth?
Most insurance plans permit one crown per tooth every five to seven years. You can bill sooner if the existing crown fails due to fracture, recurrent decay, or other documented problems. Document the failure clearly with photographs and clinical notes explaining why replacement became necessary before the standard frequency period elapsed. Some plans have lifetime maximums on crown coverage regardless of replacement necessity.
What's the difference between D2750, D2751, and D2752?
The distinction lies in the metal composition of the crown substructure. D2750 demands high noble metal with at least 60% noble metal content and 40% gold. D2751 covers predominantly noble metal crowns that don't meet the 40% gold threshold. D2752 applies to base metal alloys with minimal noble metal content. Using the wrong code based on material specifications will trigger claim denials or incorrect reimbursement.
Do I need pre-authorization for D2750?
Pre-authorization requirements fluctuate by insurance carrier and plan type. Many plans mandate pre-authorization for any crown procedure because of the cost involved. Submit the treatment plan with supporting documentation including radiographs, photographs, and clinical narrative before starting the procedure. Pre-authorization doesn't guarantee payment but confirms coverage eligibility and expected reimbursement amounts.
Can I bill D2750 if I use a different material than documented?
No. Bill the code that accurately reflects the materials used in the final restoration. If you initially planned a high noble metal crown but switched to base metal, bill D2752 instead. Intentionally billing a higher-cost code when using different materials constitutes fraud. Your laboratory work authorization and invoices must match the code billed to insurance.
What happens if insurance downgrades my D2750 claim?
Some insurance plans include alternative benefit clauses that pay based on the least expensive treatment option regardless of materials used. If your D2750 claim gets downgraded to D2752 reimbursement rates, you can bill the patient for the difference if your treatment plan disclosed this possibility. Document the patient's material choice and financial responsibility before starting treatment to avoid disputes.
How do I handle crown buildups when billing D2750?
Core buildups are billed separately using D2950 for cast post and core or D2954 for prefabricated post and core. These codes cover the foundation work needed before crown preparation when inadequate tooth structure remains. Bill the buildup code on the same date as the crown preparation, not the delivery date. Both procedures demand separate documentation showing clinical necessity.
Can I bill D2750 and a crown lengthening procedure together?
Yes, when clinical documentation supports the necessity for both procedures. Crown lengthening (D4249) prepares the tooth for crown placement by exposing more tooth structure. These procedures are typically performed on different dates, with crown preparation occurring after tissue healing. Document the clinical necessity for crown lengthening and verify the treatment plan shows both procedures were essential for successful crown placement.
What documentation do I need if insurance audits my D2750 claims?
Insurance audits demand comprehensive records demonstrating medical necessity:
Complete clinical examination notes documenting the condition necessitating crown placement
Pre-operative and post-operative radiographs showing tooth structure and crown fit
Photographs of the prepared tooth and final restoration
Laboratory work authorization specifying high noble metal composition
Written treatment plan signed by the patient acknowledging the procedure and costs
Progress notes from the preparation appointment and delivery appointment
