Quick Answer: Diagnostic imaging (D0220) and oral surgery (D7140) are routinely billed together. Pre-surgical radiographs are a clinical requirement and are separately reimbursable.
📋 Rule Summary
Detail | |
Code A | D0220 — Intraoral Periapical X-rays |
Code B | D7140 — Erupted Tooth Extraction |
Same-day billing | ✅ ALLOWED |
Code A category | Diagnostic |
Code B category | Oral Surgery |
Documentation needed | Tooth numbers, clinical notes, and separate indications for each code |
Common mistake | Assuming that because both codes appear on the same claim they will automatically be rejected — context and documentation determine the outcome |
What Is D0220 — Intraoral Periapical X-rays?
D0220 is a CDT code in the Diagnostic category. It covers intraoral periapical x-rays services and is used when the clinical record documents the appropriate indications for this procedure.
Diagnostic codes like D0220 are billed per service rendered. They require corresponding findings in the clinical chart and, for radiographic codes, the actual images retained in the patient record.
Key documentation requirements for D0220:
Tooth number(s) clearly identified for each code (D0220 and D7140)
Clinical notes documenting the separate indications for both procedures
Date of service correctly recorded for each procedure
What Is D7140 — Erupted Tooth Extraction?
D7140 is a CDT code in the Oral Surgery category. It covers erupted tooth extraction services and is used when the clinical record documents the appropriate indications for this procedure.
Oral surgery codes like D7140 require tooth numbers, the reason for the surgical procedure, and supporting radiographs. Some codes require narrative justification of complexity.
Key documentation requirements for D7140:
Tooth number(s) clearly identified for each code (D0220 and D7140)
Clinical notes documenting the separate indications for both procedures
Date of service correctly recorded for each procedure
D0220 and D7140 on the Same Day — The Bundling Rule Explained
Diagnostic imaging (D0220) and oral surgery (D7140) are routinely billed together. Pre-surgical radiographs are a clinical requirement and are separately reimbursable.
The Exception
Ensure the x-ray is taken the same day for diagnostic purposes — not just pulled from the archive — to support the separate billing.
What to Bill in Each Scenario
Clinical situation | Correct code(s) |
|---|---|
Both procedures performed at the same visit with documentation | Both D0220 and D7140 |
Only intraoral periapical x-rays was performed | D0220 |
Only erupted tooth extraction was performed | D7140 |
Procedures cannot be supported by chart documentation | Bill only the documented procedure |
Documentation Checklist
[ ] Tooth number(s) clearly identified for each code (D0220 and D7140)
[ ] Clinical notes documenting the separate indications for both procedures
[ ] Date of service correctly recorded for each procedure
[ ] Radiographic images retained in the patient record
[ ] Pre-surgical radiographs supporting the surgical indication
[ ] Narrative attached if combining uncommon code pairs on the same claim
[ ] Patient's insurance eligibility confirmed for the date of service
Billing Tips to Avoid Denial
1. Pre-surgical x-rays are always separately billable
Radiographs taken to plan or support a surgical procedure are a separate service from the surgery itself. D0220, D0230, and D0330 are commonly billed alongside extraction codes.
2. Panoramic (D0330) is particularly useful before complex extractions
For impacted or surgical extractions (D7210, D7220–D7240), a panoramic x-ray is standard of care. Most carriers cover it when billed with a surgical code.
3. Document the diagnostic purpose of the x-ray
The clinical note should state what was evaluated on the radiograph and how it informed the surgical decision. Generic notes ('x-ray taken') without findings are a common audit weakness.
4. Avoid billing x-rays already in the record
Only bill for x-rays taken at that appointment. Pulling up an existing x-ray from the record is not a separately billable service.
Frequently Asked Questions
Can D0220 and D7140 ever be billed together?
Yes, in most cases — see the bundling rule explanation above for the conditions and any exceptions.
What is the difference between D0220 and D7140?
D0220 covers intraoral periapical x-rays services, while D7140 covers erupted tooth extraction services. They belong to different CDT categories and address different clinical procedures.
Will insurance pay for D0220 and D7140 on the same claim?
Coverage depends on the specific plan. Most carriers allow this combination with documentation. Always verify with the patient's specific plan before submitting.
What documentation is needed to bill D0220 with D7140?
At minimum: tooth numbers for each procedure, clinical notes documenting separate indications, and — for complex or unusual combinations — a brief narrative explaining why both were clinically necessary on the same date.
What happens if D0220 and D7140 are denied when billed together?
Submit an appeal with supporting documentation including the clinical chart notes, radiographs (if applicable), and a narrative explaining the separate clinical purposes. Most carriers have a formal appeal process that can reverse automatic denials.
Is it upcoding or fraud to bill D0220 and D7140 on the same day?
Billing two codes that represent genuinely distinct, separately documented services is not fraud — it is accurate coding. Fraud occurs when a code is billed for a service that was not performed. Ensure your chart documentation fully supports each code submitted.
