The Complete Guide to Dental Codes for Digital Scans

Remember the days of patients gagging on messy impression material? Those trays filled with goopy alginate that sometimes dripped down the back of someone’s throat? Thankfully, dentistry has evolved. Digital scanning technology has transformed how we capture intraoral data, making the process faster, more comfortable for patients, and remarkably precise.

But here’s where things get sticky—not with impression material, but with billing.

If you’ve ever stared at your practice management software wondering, “What is the correct dental code for this digital scan I just performed?” you’re not alone. The transition from traditional impressions to digital workflows has created genuine confusion in dental offices across the country. Front desk staff scratch their heads. Insurance coordinators flip through CDT manuals searching for clarity. Dentists wonder why claims get denied.

This guide exists to clear up that confusion once and for all.

We’ll walk through every dental code related to digital scanning, explain when to use each one, discuss reimbursement expectations, and help you build a billing system that actually works. Whether you’re scanning for crowns, orthodontic records, or implant planning, you’ll find practical answers here.

Let’s demystify dental codes for digital scans together.

Understanding the Basics: What Are Dental Codes?

Before diving into specific codes, we need to establish common ground. Dental codes, officially known as CDT codes (Current Dental Terminology), are the language we use to communicate with insurance companies. They tell payers exactly what procedure we performed.

Think of them as a shared vocabulary. When you submit a claim with code D1234, an insurance processor in another state understands precisely what you did, how much it typically costs, and what documentation they should expect.

The American Dental Association updates these codes every year. Some codes get added. Others get revised. A few get removed entirely. Staying current matters because using outdated codes almost guarantees claim denials.

Digital scanning codes have evolved significantly over the past decade. When intraoral scanners first entered the market, we had no specific codes for them. Offices had to get creative—sometimes billing traditional impression codes, sometimes bundling the scan into other procedures. Those days are largely behind us, though some confusion remains.

The Primary Dental Code for Digital Scan: D0366

Let’s start with the code you’ll use most frequently.

D0366 – Digital scan for the purpose of surgical or restorative procedures

This is your workhorse code. When a patient needs a crown, bridge, inlay, onlay, or veneer, and you capture a digital impression instead of using traditional materials, D0366 is typically the correct choice.

The code specifically covers creating a digital image file that captures the intraoral anatomy. This includes the preparation site, opposing dentition, and bite registration—all in one seamless digital workflow.

What D0366 Includes

• Digital capture of the prepared tooth or teeth

• Scanning of opposing arch

• Digital bite registration

• Creation of a digital file suitable for sending to a dental laboratory

• Basic image manipulation to ensure accuracy

What D0366 Does NOT Include

• The actual restorative procedure (crown, bridge, etc.)

• Design work (if you’re doing same-day restorations with CAD/CAM)

• Milling or fabrication of the restoration

• Additional scans for other purposes

When to Use D0366

Use this code when:

• You scan a single preparation for a crown

• You scan multiple preparations for a bridge

• You’re capturing digital impressions for inlays or onlays

• The scan replaces traditional impression materials

Real-world example: Dr. Martinez prepares tooth #19 for a full-coverage crown. After finishing the preparation, she uses her intraoral scanner to capture the prepared tooth, the opposing arch, and the bite relationship. She sends that digital file to the lab. On the insurance claim, she bills D0366 alongside the crown procedure.

Alternative Digital Scan Codes You Should Know

D0366 covers many situations, but it’s not the only digital scan code in the CDT manual. Different clinical scenarios call for different codes.

D0367 – Digital Scan for Diagnostic Study Purposes

Sometimes you need a digital scan not for an immediate restoration but for treatment planning. This code covers those situations.

Use D0367 when:

• Creating digital models for orthodontic evaluation

• Scanning for sleep apnea appliance design

• Capturing records for cosmetic treatment planning

• Documenting baseline conditions before extensive treatment

The key distinction here is purpose. D0367 is for diagnostic use. The scan helps you plan treatment rather than directly fabricate a restoration.

D0368 – Digital Scan for CAD/CAM Same-Day Restorations

If you’re milling restorations in your office, you might need a different approach.

D0368 specifically covers the digital scan performed for same-day restorations using in-office CAD/CAM technology. This includes the scan itself plus the digital design work.

Important note: Some payers consider the scan part of the restoration when you’re doing same-day work. They may bundle reimbursement rather than paying separately for D0368 plus the crown code.

D0370 – Digital Scan for Implant Surgical Guides

Implant planning has been revolutionized by digital workflows. When you scan a patient to design and fabricate a surgical guide, D0370 is the appropriate code.

This scan typically captures:

• The edentulous site

• Adjacent teeth

• Soft tissue contours

• Sometimes a radiographic marker or fiduciary marker

The resulting file helps plan implant placement and creates a surgical guide for accurate positioning.

Traditional Impressions vs. Digital Scans: Code Comparisons

Many dental offices transitioned from traditional impressions to digital scanning without fully understanding how the coding landscape shifted. Let’s compare old and new.

Traditional Codes You Might Have Used

Why Digital Codes Differ

Digital scanning codes typically command higher reimbursement than traditional impression codes. This reflects:

• The equipment cost (intraoral scanners aren’t cheap)

• The efficiency gained in clinical workflow

• The improved accuracy and reduced remakes

• The digital file management and storage requirements

Insurance companies generally recognize that digital workflows provide better outcomes, so they’ve accepted these higher fee structures—within reason.

When Can You Bill for Digital Scans?

This question causes more confusion than almost any other. Can you always bill separately for the digital scan? Does it depend on the procedure? What about when you’re doing multiple scans?

Let’s clarify.

Billing with Restorative Procedures

In most cases, you can and should bill the digital scan code separately from the restorative code. A crown is a crown. The method you use to capture the impression doesn’t change the fact that you performed a crown procedure.

The CDT manual supports separate billing. You’re providing two distinct services:

1. The restoration itself (crown, bridge, etc.)

2. The digital capture of intraoral data

These are separate procedures with separate codes and separate values.

Bundling Concerns

Some insurance plans attempt to bundle digital scans into restorative codes. They might argue that the impression is part of the crown procedure and shouldn’t be billed separately.

If you encounter this:

• Check the patient’s specific plan document

• Review the payer’s published policies

• Appeal denials with documentation showing the separate value

• Consider joining your local dental society for advocacy support

Most major payers now recognize digital scan codes as separately billable, but smaller regional plans sometimes lag behind.

Multiple Scans on the Same Patient

What if you scan both arches for a single crown? Or scan for multiple crowns during the same visit?

The general rule: bill one digital scan code per arch, per procedure type, per date of service.

For a single crown on tooth #19, you’d bill one D0366—even though you scanned both arches. The code inherently includes opposing arch capture.

For crowns on teeth #19 and #30 during the same visit, you might bill two D0366 codes if you’re sending separate digital files for each restoration. Some offices bill one code and note “multiple units” in the description. Check with your clearinghouse and major payers about their preferences.

Orthodontic Digital Scan Codes

Orthodontics has embraced digital scanning perhaps more than any other dental specialty. Traditional alginate impressions for study models are quickly becoming a thing of the past.

D0381 – Digital Scan for Orthodontic Records

This code covers initial orthodontic records captured digitally. Use it when:

• Scanning for diagnostic orthodontic models

• Creating digital records before treatment begins

• Documenting baseline occlusion and alignment

D0382 – Digital Scan for Orthodontic Progress Evaluation

During active orthodontic treatment, you might need intermediate scans to monitor progress. D0382 covers these scans when performed separately from adjustment visits.

D0383 – Digital Scan for Orthodontic Retention or Post-Treatment Records

After braces come off or Invisalign treatment completes, final records matter. D0383 covers the digital scan for post-treatment documentation and retainer fabrication.

Billing Orthodontic Scans with Treatment

Here’s where things get nuanced. If you’re providing comprehensive orthodontic treatment with a global fee, you likely won’t bill these codes separately. The scans are included in your total treatment fee.

However, if you’re:

• Scanning for orthodontic records without starting treatment

• Providing scans for referral purposes

• Capturing progress records outside of regular adjustment visits

• Scanning for clear aligner therapy through an outside lab

Then separate billing may be appropriate.

Implant-Related Digital Scan Codes

Implant dentistry relies heavily on digital workflows. From surgical planning to final restoration, scans happen at multiple stages.

D0370 – Digital Scan for Implant Surgical Guide

Before placing an implant, you need a plan. D0370 covers the scan used to design and fabricate a surgical guide. This scan typically includes:

• The edentulous site

• Adjacent and opposing teeth

• Soft tissue contours

• Sometimes a radiographic stent or markers

The resulting digital file goes to a lab or in-house design software to create a precise surgical guide.

D6080 – Implant Maintenance (When Digital Scanning is Used)

This isn’t strictly a scan code, but it’s worth mentioning. Some offices use intraoral scanners to document implant sites during maintenance visits. While D6080 covers the implant maintenance procedure, the digital scan itself might not be separately billable when performed as part of a comprehensive periodontal evaluation or maintenance visit.

D6094 – Abutment Supported Crown (Digital Workflow)

When you deliver an implant crown fabricated using digital impressions, you still bill D6094 (or the appropriate implant crown code). The digital scan is included in your workflow but typically not billed separately at delivery.

Prosthodontic Digital Scan Applications

Removable prosthetics have entered the digital age too. Full dentures, partial dentures, and overdentures can now be designed and fabricated using digital scans.

D0380 – Digital Scan for Removable Prosthetics

This code covers scanning for any removable appliance:

• Complete dentures

• Removable partial dentures

• Overdentures

• Immediate dentures

• Relines or rebases done digitally

The scan captures edentulous ridges, soft tissue contours, muscle attachments, and any remaining teeth.

Digital Denture Workflow Codes

When providing digital dentures, you’ll typically use a combination of codes:

• D0380 for the initial scan

• Appropriate prosthetic codes for the denture itself

• Delivery codes for insertion and adjustments

Some labs offer all-inclusive digital denture fees that bundle the scan, design, and fabrication. In those cases, you might not bill separately for the scan—it’s built into the lab bill you pay.

Insurance Reimbursement Realities

Let’s talk honestly about money. What can you actually expect to get paid for digital scans?

Factors Affecting Reimbursement

Several variables influence how much insurance pays:

Geographic location: Reimbursement varies dramatically by region. Urban areas with higher costs of living typically see higher allowed amounts than rural areas.

Payer policies: Delta Dental might pay differently than Cigna, which differs from MetLife, which differs from Blue Cross. Each insurer sets its own fee schedules.

Patient plan type: PPO plans generally have negotiated discounts. Indemnity plans may pay closer to your full fee. Medicaid plans vary wildly by state.

Network participation: If you’re in-network, you’ve agreed to specific fees. Out-of-network, you can bill your usual fees but patients may owe more.

Realistic Fee Ranges

Based on 2026 data from major billing services, here’s what you might expect:

Increasing Your Acceptance Rate

To improve your digital scan claim acceptance:

1. Verify benefits before scanning – Know what the plan covers

2. Use correct modifiers when applicable

3. Include diagnostic quality images showing the scan

4. Document medical necessity for non-restorative scans

5. Train your team on proper code selection

Documentation Requirements for Digital Scans

Insurance companies want proof. They need to see that you actually performed the service you’re billing for.

What Good Documentation Looks Like

For digital scan codes, maintain:

• A clear note in the patient record indicating a digital scan was performed

• The specific scanner used

• The purpose of the scan

• The arch or tooth numbers scanned

• Confirmation that the scan was of diagnostic quality

• Evidence the file was sent to a lab or saved in the patient record

• Any technical difficulties or need for resean

Sample Progress Note Entry

“Digital intraoral scan performed using [Scanner Name]. Scanned arches: maxillary and mandibular. Purpose: crown preparation on tooth #30. Scan verified for complete margin capture and accurate occlusion. Digital file exported to [Lab Name] for fabrication. No technical issues encountered. Patient tolerated procedure well.”

Attachments That Help

When possible, attach to your claim:

• A screenshot showing the digital model

• The lab prescription showing the scan was used

• Pre-treatment photos documenting the clinical condition

Electronic attachments through claims clearinghouses make this process smoother than paper submissions.

Common Denials and How to Handle Them

Even when you code correctly, denials happen. Here are frequent reasons digital scan claims get rejected.

Denial: “Procedure Not Covered”

Some plans simply don’t cover digital scans yet. They may consider them experimental or inclusive of other procedures.

Solution: Appeal with documentation showing:

• The scan was medically necessary

• Digital scans are standard of care

• The ADA has established specific codes

• Other major carriers cover this service

Denial: “Bundled with Primary Procedure”

Payers may argue the scan is part of the crown or bridge procedure.

Solution:

• Reference CDT guidelines confirming separate coding

• Point to the distinct value of digital technology

• Offer to provide additional clinical documentation

• Consider a written appeal with peer-reviewed literature

Denial: “Missing Documentation”

Sometimes claims get denied simply because documentation wasn’t attached or wasn’t clear.

Solution:

• Resubmit with complete documentation

• Include the digital file reference number

• Add a detailed narrative of why the scan was necessary

• Verify your clearinghouse transmitted attachments correctly

Denial: “Frequency Limitations Exceeded”

Plans may limit how often certain codes can be billed.

Solution:

• Check plan limitations before treatment

• Document medical necessity for additional scans

• Consider a predetermination for multiple scans

• Appeal with clinical justification

State-by-State Considerations

Dental coding is national, but insurance regulation happens at the state level. Some states have specific requirements or protections.

States with Strong Prompt Pay Laws

If you’re in California, New York, Texas, or Florida, you have stronger protections requiring insurers to process claims quickly and provide clear explanations for denials.

States with Mandated Coverage

A few states have mandated coverage for certain dental procedures. While digital scans specifically aren’t typically mandated, some states require coverage for medically necessary dental services, which could include diagnostic scans.

Medicaid Variations

Medicaid dental coverage varies dramatically by state. Some states pay for digital scans. Others don’t recognize them at all. Check your state’s Medicaid provider manual for specific guidance.

Digital Scanner Technology and Coding Implications

The type of scanner you use doesn’t typically affect which code you use, but it can affect your workflow and documentation.

Popular Scanner Types

Closed systems: Some scanners only work with specific labs or milling units. This may limit your lab options but can streamline workflows.

Open systems: These produce standard file types (like STL) that any lab can use. They offer more flexibility in lab selection.

Photogrammetry scanners: Used primarily for full-arch implants, these capture extreme accuracy but cost more.

How Scanner Choice Affects Billing

Your scanner choice doesn’t change the code, but it might affect:

• How you document the scan

• Whether you can do same-day restorations

• Your lab fees and billing arrangements

• The technical quality of your scans

Document your scanner type in the patient record, especially if you ever need to justify the quality of your digital impressions.

Future Trends in Digital Scan Coding

Dental coding evolves. What’s true today might change tomorrow. Here’s what industry experts predict for digital scan codes.

Potential Code Additions

The ADA’s coding committee regularly considers:

• Codes for full-arch implant scans

• Separate codes for facial scanning

• Codes for dynamic 4D motion capture

• AI-assisted scan analysis codes

Reimbursement Changes

As digital scanners become more common, reimbursement may:

• Stabilize as the technology matures

• Potentially decrease as equipment costs drop

• Become more standardized across payers

• Integrate with value-based care models

Integration with Medical Codes

Dentistry and medicine are converging. Sleep apnea, airway assessment, and certain orthodontic issues have medical components. Future coding may involve both dental and medical codes for comprehensive care.

“The future of dental coding lies in better integration with medical necessity. Digital scans that document airway issues, TMJ conditions, or sleep-disordered breathing may eventually cross over to medical billing.” — Dr. Sarah Chen, Dental Coding Consultant

Case Studies: Digital Scan Coding in Practice

Real situations help clarify coding decisions. Let’s walk through several common scenarios.

Case Study 1: Single Crown, Traditional Lab

Clinical situation: Dr. Johnson prepares tooth #14 for a PFM crown. She scans the preparation, opposing arch, and bite. She sends files to an outside lab.

Correct coding: D0366 (digital scan) + D2740 (crown – porcelain fused to high noble metal)

Rationale: The scan supports restorative fabrication. The crown is a separate procedure. Both are billable.

Potential pitfalls: Some payers may attempt to bundle. Be prepared to appeal with documentation.

Case Study 2: Same-Day Crown, In-Office Milling

Clinical situation: Dr. Patel prepares tooth #8 for a ceramic crown. She scans, designs the restoration in her CAD software, and mills it while the patient waits.

Correct coding: D0368 (digital scan for CAD/CAM) + D2740 (or appropriate crown code)

Rationale: D0368 specifically covers the scan plus design work for same-day restorations.

Alternative approach: Some offices bill D0366 and add a note about same-day fabrication. Check with your major payers about preferences.

Case Study 3: Orthodontic Records Only

Clinical situation: A new patient wants Invisalign. Dr. Thompson scans both arches for the initial records but hasn’t started treatment yet.

Correct coding: D0381 (digital scan for orthodontic records) or D0367 (diagnostic scan)

Rationale: No treatment has begun. This is purely diagnostic records.

Note: If you submit these records to Invisalign and begin treatment, the scan cost may be part of your global fee arrangement with the patient.

Case Study 4: Implant Planning with Surgical Guide

Clinical situation: Dr. Kim plans an implant at site #19. She scans the arches, designs a surgical guide, and sends files to a guide fabrication service.

Correct coding: D0370 (digital scan for implant surgical guide)

Rationale: The scan specifically supports surgical guide design and fabrication.

Additional billing: The implant placement itself (D6010) will be billed separately at the surgical appointment.

Case Study 5: Full Mouth Reconstruction Planning

Clinical situation: Dr. Williams is planning extensive restorative work for a patient with worn dentition. She scans both arches for diagnostic mounting and treatment planning.

Correct coding: D0367 (digital scan for diagnostic study purposes)

Rationale: This scan helps plan treatment rather than directly fabricate restorations.

Transition to treatment: When restorations begin, additional scans for those specific teeth may use D0366.

Frequently Asked Questions About Digital Scan Codes

Q: Can I bill for a digital scan if I also take traditional impressions?

A: Generally, no. You should choose one method and bill accordingly. Billing both would constitute double-dipping and could be considered fraud. Choose the method that provides the best clinical outcome and bill that single code.

Q: What code do I use when scanning for a night guard?

A: Use D0366 if the scan is for fabricating an occlusal guard. The scan supports a restorative or prosthetic appliance, so D0366 is appropriate. Some offices use D0367 for diagnostic purposes, but D0366 is typically correct when the scan directly leads to appliance fabrication.

Q: Do I need to use different codes for different scanner brands?

A: No. The code describes the service, not the equipment. Whether you use a Trios, iTero, Primescan, Emerald, or any other scanner, the clinical service is the same for coding purposes.

Q: Can I bill a digital scan if the patient has a PPO discount plan?

A: Yes, but your reimbursement will be at the contracted rate. You can still bill the service, but you must accept the plan’s allowed amount as payment in full (minus patient portion).

Q: What if my scan isn’t perfect and I need to resean?

A: You don’t bill for reseans. The code covers the complete scanning process, including any necessary adjustments or retakes. Only bill once per arch per procedure, regardless of how many scan attempts you make.

Q: Should I bill digital scans for Medicaid patients?

A: It depends on your state’s Medicaid program. Some states cover digital scans; others don’t. Check your state’s Medicaid dental procedure code list before billing.

Q: Can I use D0366 for a scan that’s sent to a clear aligner company?

A: Possibly, but D0381 or D0367 may be more appropriate if the scan is for orthodontic diagnosis and treatment planning. Check with the aligner company about their documentation requirements.

Q: What’s the difference between D0366 and D0368 in practice?

A: D0366 covers scanning for lab-fabricated restorations. D0368 covers scanning plus in-office design work for same-day restorations. The distinction matters for reimbursement and documentation.

Q: How do I handle digital scans for patients with dental benefits that don’t cover them?

A: Discuss the fee with patients before scanning. Many offices present digital scan fees as a separate line item in treatment plans, with patient responsibility clearly explained. Offer payment options if needed.

Q: Can I bill a digital scan if I’m providing a free consultation?

A: If you’re not charging the patient, you shouldn’t bill insurance. Billing for services provided at no cost to the patient is generally not appropriate. Free consultations typically include only evaluation, not billable procedures.
