D7240 Dental Code: Extraction of Erupted Tooth Requiring Removal of Bone

Tooth extraction is one of the most common dental procedures, but not all extractions are the same. While simple extractions (D7140) involve removing a fully erupted tooth with forceps, D7240 refers to a more complex surgical extraction requiring bone removal and/or tooth sectioning.

This article provides an in-depth exploration of D7240, including its clinical applications, procedural steps, billing considerations, and postoperative management. Whether you’re a dental professional, a student, or a patient seeking clarity, this guide will offer valuable insights into this essential dental code.

2. Understanding Dental Procedure Codes (D-Codes)

Dental procedures are categorized using Current Dental Terminology (CDT) codes, maintained by the American Dental Association (ADA). These codes standardize billing and insurance claims.

Common Extraction Codes:

D7240 is specifically used when the extraction involves bone removal, tooth division, or flap elevation—making it a more complex and time-consuming procedure.

3. What is D7240 Dental Code?

D7240 is defined as:

“Extraction of an erupted tooth requiring removal of bone and/or sectioning of tooth, and including elevation of mucoperiosteal flap if indicated.”

Key Features of D7240:

• Bone Removal (Osteotomy): Necessary when a tooth is partially submerged in bone.

• Tooth Sectioning: Dividing a multi-rooted tooth (e.g., molars) for easier removal.

• Flap Elevation: Reflecting gum tissue to access the underlying bone and tooth.

4. When is D7240 Used?

This code applies when a tooth cannot be extracted using simple techniques due to:
✔ Fractured roots
✔ Severe decay compromising tooth structure
✔ Hypercementosis (excessive cementum buildup)
✔ Dense surrounding bone (e.g., mandibular molars)
✔ Teeth with curved or divergent roots

5. Differences Between D7240 and Other Extraction Codes

6. Step-by-Step Procedure for D7240

1. Diagnosis & Imaging (X-ray/CBCT to assess bone and root anatomy).

2. Anesthesia Administration (Local or sedation).

3. Flap Elevation (If needed).

4. Bone Removal (Using a surgical bur or osteotome).

5. Tooth Sectioning (For multi-rooted teeth).

6. Tooth Removal (Elevators and forceps).

7. Socket Debridement & Suturing.

7. Preoperative Considerations

• Medical History Review (Bleeding disorders, bisphosphonates).

• Antibiotic Prophylaxis (If indicated for high-risk patients).

• Informed Consent (Discuss risks: nerve injury, sinus perforation).

8. Surgical Techniques for Complex Extractions

• Piezosurgery (Ultrasonic bone cutting for precision).

• Luxation Techniques (Controlled tooth loosening).

• Socket Preservation (For future implants).

9. Postoperative Care and Complications

Aftercare Instructions:

• Bite on gauze for 30-60 minutes.

• Avoid smoking & straws (prevent dry socket).

• Soft diet for 2-3 days.

Potential Complications:

• Dry socket (alveolar osteitis)

• Nerve injury (paresthesia)

• Infection or delayed healing

10. Billing and Insurance Considerations

• Insurance Coverage: Most plans cover 50-80% of D7240.

• Documentation Required: X-rays and operative notes justifying complexity.

• Alternative Codes: If only soft tissue impaction, use D7210.

11. Common Questions About D7240

• “Is D7240 painful?” (No, anesthesia ensures comfort.)

• “How long does healing take?” (1-2 weeks for initial recovery.)

12. Conclusion

D7240 is a critical dental code for complex extractions requiring bone removal or tooth sectioning. Proper diagnosis, surgical skill, and postoperative care ensure successful outcomes. Understanding this procedure helps dentists, insurance providers, and patients navigate treatment effectively.

13. FAQs

Q1: How much does a D7240 extraction cost?
A: Typically $300-$800, depending on complexity and location.

Q2: Does D7240 require stitches?
A: Often yes, due to flap elevation.

Q3: Can I drive home after a D7240 procedure?
A: If only local anesthesia is used, yes. With sedation, arrange a ride.
