The D0150 dental code reports a comprehensive oral evaluation for a new or established patient. The exam builds a full baseline of oral health. It sits in the Diagnostic category of the CDT code set.
The American Dental Association (ADA) defines D0150 for a new patient or a major change in status. It is not a longer version of the recall exam. Carriers reclassify it to D0120 when the note does not fit the descriptor.
This guide covers the D0150 descriptor, the cost, real clinical scenarios, and the reimbursement rules. Practices that route diagnostic claims through specialist dental billing services keep new-patient exams clean and paid. The sections below map the full billing picture for D0150.

What Is the Description of Dental Code D0150?
The D0150 dental code describes a comprehensive oral evaluation for a new or established patient. The exam records a full baseline of the mouth. It includes charting, a tissue exam, and a written treatment plan.
The ADA descriptor sets three coding-appropriate pathways for D0150. It applies to a new patient or an established patient with a significant health change. It also applies to one absent from active treatment for three or more years.
D0150 is the full baseline exam, not a longer recall exam.
A comprehensive evaluation includes full periodontal charting and complete tissue examination. It produces a documented treatment plan. That depth separates D0150 from the periodic recall code.
How Does D0150 Differ From D0120, D0180, and D0145?
D0150 differs from its neighbors by depth and by patient pathway. A routine recall routes to the periodic code. A periodontal focus routes to the comprehensive periodontal code. The table maps each option.
| CDT Code | Evaluation | When It Applies |
|---|---|---|
| D0150 | Comprehensive oral evaluation, new or established patient | New patient, significant change, or 3 or more years absent |
| D0120 | Periodic oral evaluation, established patient | Routine recall for a patient of record |
| D0180 | Comprehensive periodontal evaluation | Patient with signs or risk factors for periodontal disease |
| D0140 | Limited oral evaluation, problem-focused | Specific complaint, emergency, or trauma |
| D0145 | Oral evaluation for a patient under three years of age | Young child exam with a caregiver counseling component |
A new-patient baseline is D0150. A routine recall is D0120. A periodontal-focused workup is D0180. Matching the code to the pathway prevents reclassification and frequency denials.
Can D0150 Be Billed at Every Visit?
No, D0150 does not apply to routine recall visits. An established patient returning for a six-month check receives D0120. D0150 fits only the new-patient, significant-change, or three-year pathways.
What Is the Difference Between D0150 and D0180?
The difference is clinical focus. D0150 is a full oral baseline, while D0180 is a comprehensive periodontal evaluation. D0180 targets a patient with signs or risk factors for periodontal disease.
What Elements Does a D0150 Evaluation Include?
A D0150 evaluation covers the parts that make it comprehensive rather than periodic. The record documents each element. The core elements appear below.
- Review of the medical and dental history
- Extraoral examination of the head, neck, lymph nodes, and jaw joint
- Intraoral examination of teeth, restorations, and prostheses
- Full periodontal charting and a soft tissue oral cancer screening
- A written treatment plan for identified needs
The periodontal charting and treatment plan carry the comprehensive label. A D0150 without them reads as a periodic exam. The note lists the elements the dentist performed.
Which Records Support a D0150 Claim?
Documentation for D0150 shows a full baseline exam on a qualifying patient. The record ties the exam to the pathway. The items below support the claim.
- The new-patient status or the qualifying pathway
- Full periodontal charting and the tissue exam
- The written treatment plan produced at the visit
- The last comprehensive evaluation date for established patients
- The date of service for frequency tracking
Carriers can and do request the exam note to confirm charting and treatment planning on a D0150 claim.
Practices with steady new-patient flow centralize eligibility checks through outsourced dental billing and coding support. Verified frequency at the source prevents the reclassification to a periodic exam.
What Is the Cost of Dental Code D0150?
The cost of D0150 ranges from about $55 to $130 in 2026. The national average office fee sits near $80 to $130. The full baseline exam prices above the recall exam.
The exam often bundles into a new-patient visit with radiographs and a cleaning. Each service carries its own code and fee. The plan pays for the exam on its own line.
| Cost Element | Typical 2026 Amount | Notes |
|---|---|---|
| D0150 office fee | $55 to $130 | Per comprehensive evaluation |
| National average (ADA survey) | About $80 to $130 | Single evaluation |
| Complete radiograph series (D0210) | $130 to $180 | Common new-patient imaging |
| Adult prophylaxis (D1110) | $95 to $130 | Common same-visit cleaning |
A new-patient estimate often shows the exam, radiographs, and cleaning together. The plan adjudicates each code separately. Diagnostic services usually carry the highest coverage.
How Do Dental Plans Cover D0150?
Most dental plans cover D0150 at 100% within frequency as a diagnostic benefit. Plans limit the exam to once per provider over a set window. A second full evaluation in that window falls to the patient or to D0120.
- Many plans allow D0150 once per provider every 24 to 36 months
- Some plans limit D0150 to once per provider lifetime
- Subsequent exams in the window bill as D0120
- Coordination of benefits applies to patients with dual coverage
A plan lookback window controls when D0150 becomes payable again. A correctly coded D0150 can still be denied on frequency. The window and the descriptor operate as two separate gates.
What Factors Change the D0150 Fee?
Regional market and practice setting move the D0150 fee the most. The exam remains a diagnostic service across markets. Bundled new-patient services drive the larger visit total.
- Regional market, since metro fees exceed rural fees
- Practice setting, such as a specialty office versus a general one
- Same-visit services, including radiographs and a cleaning
- Plan fee schedules for in-network providers
What Are Example Clinical Scenarios for Dental Code D0150?
D0150 applies when a patient needs a full baseline evaluation under a qualifying pathway. The scenarios below show clean reporting patterns. Each pairs the pathway with the coding decision.
Scenario 1: New Patient First Visit
A new patient presents for a first visit with no prior record at the practice. The dentist completes charting, a tissue exam, and a treatment plan. The practice reports D0150 with the supporting exam note.
The note records the full baseline and the treatment plan. The new-patient status supports the D0150 code. The plan pays D0150 within its frequency window.
Scenario 2: Established Patient Returning After a Four-Year Absence
An established patient returns after four years away from active treatment. The dentist rebuilds the baseline with full charting and a new plan. The practice reports D0150 under the three-year absence pathway.
The note records the gap since the last comprehensive evaluation. The absence exceeds three years, which supports D0150. The last evaluation date confirms the pathway for the plan.
Scenario 3: Established Patient at a Routine Recall
An established patient returns for a routine six-month check with no major change. The dentist performs a periodic evaluation. The correct code is D0120, not D0150.
A routine recall does not meet the D0150 pathways. Billing D0150 at recall draws utilization review. The periodic code fits the visit and protects both codes.
What Are the D0150 Rules for Successful Reimbursement?
Successful D0150 reimbursement rests on the qualifying pathway, the frequency window, and clean documentation. The rules below reduce denials and reclassifications. Each rule targets a known payer behavior.
How the Descriptor and the Frequency Window Work Together
Two gates govern D0150 for an established patient. The ADA descriptor sets when the code is coding-appropriate. The carrier’s lookback window sets when the plan pays it.
- Confirm the patient meets a D0150 pathway before coding
- Check the carrier’s lookback window for payment eligibility
- Bill subsequent in-window exams as D0120
- Document the significant change or the three-year absence
A correctly coded D0150 can still be denied in the plan window. The descriptor and the window are separate tests. Meeting both keeps the claim clean.
Can D4355 and D0150 Be Billed Together on the Same Day?
Yes. D4355 full-mouth debridement can be reported on the same date as D0150 under current ADA guidance. The same-day pairing does not apply to D0180. The note supports both procedures separately.
When to Use D0150 Versus D0120 on an Established Patient
Use D0150 only for a qualifying pathway on an established patient. Use D0120 for routine recall exams. Billing D0150 at every recall is a flagged utilization pattern.
- Confirm a new-patient status, a significant change, or a three-year absence
- Check the plan lookback window for D0150
- Use D0120 for routine change detection
- Document the pathway that supports the D0150 code
A D0150 code on every visit signals overuse to the plan. The carrier expects the periodic code for routine recalls. Correct selection protects both codes across the patient’s history.
How to Keep D0150 Documentation Audit Ready
Audit-ready D0150 notes show full charting, the tissue exam, and the treatment plan. Carriers request notes when frequency or definition is in question. Consistent notes clear those requests fast.
- Record full periodontal charting at the visit
- Document the oral cancer screening result
- Keep the written treatment plan with the exam record
- Note the qualifying pathway and the last evaluation date
Practices with steady new-patient flow often compare vendors before outsourcing. A review of the best dental billing companies in the USA helps weigh diagnostic accuracy, eligibility workflows, and turnaround. Documentation quality at the source still drives the D0150 outcome.
What Is the Key Takeaway for D0150 Billing?
The D0150 dental code pays when a qualifying patient receives a full baseline evaluation within the frequency. The charting, the treatment plan, and the pathway carry the claim. Correct use of D0150 keeps new-patient revenue clean and defensible.
