D7311 Dental Code: Alveoloplasty in Conjunction with Extractions — One to Three Teeth or Tooth Spaces, per Quadrant (Billing Guide 2026)

Reviewed by Morgan Heminger · Updated September 23, 2026

What Is D7311? (CDT Code Overview)

CDT code D7311 is the alveoloplasty dental code for recontouring and smoothing the jawbone ridge during extractions when one to three teeth or tooth spaces in a quadrant are involved. It belongs to the Oral & Maxillofacial Surgery category of CDT codes (Alveoloplasty, Preparation of Ridge subcategory). It is the ADA code for alveoloplasty in conjunction with extractions on a small area; four or more teeth or spaces use D7310, and ridge work without extractions is D7320 or D7321.

When Should You Use D7311?

The D7311 dental code describes "alveoloplasty in conjunction with extractions – one to three teeth or tooth spaces, per quadrant." This CDT code applies when a dentist reshapes or smooths the alveolar ridge (the bone supporting teeth) while simultaneously extracting one to three teeth within a single quadrant. It differs from D7310, which applies when alveoloplasty accompanies extractions of four or more teeth per quadrant. D7311 should only be chosen when the alveoloplasty represents a separate and substantial procedure beyond the standard smoothing that happens during regular extractions.

Quick reference: Use D7311 when the clinical scenario specifically matches alveoloplasty with extractions. Do not use this code as a substitute for related procedures in the same category. Consider whether D7310 (Alveoloplasty with Extractions) or D7320 (Alveoloplasty Without Extractions) might be more appropriate instead.

D7311 vs. Similar CDT Codes: Key Differences

Dental teams frequently confuse D7311 with other codes in the other surgical extractions range. Here is how D7311 differs from the most commonly mixed-up codes:

Documentation Requirements for D7311

Proper documentation is crucial for successful reimbursement of D7311. The clinical records should clearly outline:

• The count of teeth removed in the quadrant (one to three).
• The particular reason for alveoloplasty (such as sharp bone edges, uneven ridge, or prosthetic preparation).
• Information demonstrating that the alveoloplasty exceeded the smoothing normally done during extraction.
• Before and after radiographs or intraoral photographs, when available, to justify the necessity and scope of the treatment.

Typical clinical situations include ridge preparation for partial dentures or addressing bone irregularities that could interfere with healing or prosthetic placement. Always make sure documentation clearly distinguishes D7311 from standard extraction procedures.

Documentation checklist for D7311:

• Patient chief complaint and relevant medical/dental history clearly recorded.
• Clinical findings that support the use of D7311 specifically (not a more general or more specific code).
• Any diagnostic tests, imaging, or supplementary data that justify the procedure.
• Treatment plan with rationale connecting the diagnosis to the procedure coded as D7311.
• Post-procedure notes, including outcomes and follow-up recommendations.

Insurance and Billing Guide for D7311

To improve reimbursement and reduce denials when submitting D7311:

• Check the patient's insurance coverage and frequency limits for surgical treatments prior to procedure.
• Provide a comprehensive narrative explaining the necessity of alveoloplasty beyond the extraction(s).
• Attach supporting materials, including clinical records and radiographs, with the submission.
• When claims are denied, examine the Explanation of Benefits (EOB) for denial reasons and prepare to file an appeal with additional documentation if required.
• Monitor accounts receivable (AR) carefully to ensure prompt follow-up on pending claims.

Most insurance companies examine D7311 claims carefully because of potential overlap with standard extraction procedures, making clear and complete documentation essential for avoiding denials.

Common denial reasons for D7311: Lack of clinical documentation, frequency limitations exceeded, code mismatch with diagnosis, or missing prior authorization. When appealing a denied D7311 claim, include a detailed narrative explaining why the procedure was necessary, supporting clinical evidence, and relevant imaging or test results. Many practices find that well-documented first submissions dramatically reduce the need for appeals.

What major payers publish about D7311:

• Aetna asks for a current dated full-mouth series and/or panoramic X-ray with D7310 and D7311 claims (Aetna Claim Documentation Guidelines, July 2025). Because third molars are not replaced with a prosthesis, Aetna treats bone contouring at a third molar site as part of the extraction, with no separate benefit for the alveoloplasty (Aetna Dental Clinical Policy Bulletin 010, March 2026).
• Delta Dental of Virginia does not allow a separate fee for D7311 when the same office does surgical extractions (D7210 to D7230) in the same surgical area on the same day (Delta Dental of Virginia Participating Dentists' Handbook, 2026).
• UnitedHealthcare considers alveoloplasty indicated for bone recontouring during extractions or before a prosthesis, but not when removing bone would harm vital structures or for patients who have had head and neck radiation (UnitedHealthcare Alveoloplasty and Vestibuloplasty policy DCP028.13, September 2026).

These are the payers' published policy documents; the patient's own plan can set different frequencies and alternate benefits, so confirm them during insurance verification.

Real-World Case Example: Billing D7311

A patient presents requiring a procedure consistent with D7311 (alveoloplasty with extractions). The treating dentist documents the clinical findings, performs the procedure as indicated, and records detailed notes including the diagnosis, technique, and outcome. The billing team verifies insurance coverage, submits the claim with D7311 and supporting documentation, and follows up to ensure timely reimbursement. When the initial claim is processed, the practice reviews the Explanation of Benefits and addresses any discrepancies promptly.

Frequently Asked Questions About D7311

Can D7311 be billed for alveoloplasty performed in multiple quadrants during the same visit?

D7311 should be reported per quadrant when alveoloplasty is performed alongside extractions. When the procedure is completed in multiple quadrants during a single appointment, you may report D7311 for each quadrant treated, as long as your documentation clearly demonstrates the medical necessity and scope of work performed in each specific area. Always verify with the specific insurance carrier, as policies and coverage rules can vary significantly between payers. Maintaining thorough documentation for D7311 will strengthen your position in any audit or appeal scenario.

Does D7311 qualify for medical insurance coverage, or is it limited to dental benefits only?

D7311 is typically classified as a dental procedure code and is generally covered by dental insurance plans. In exceptional circumstances where alveoloplasty is medically necessary due to trauma, pathological conditions, or other medical indications, certain medical insurance carriers may provide reimbursement. It's essential to verify coverage with the specific insurer and provide comprehensive documentation when submitting claims to medical insurance.

What are the most frequent causes of D7311 claim denials, and what steps can prevent them?

Frequent denial reasons include inadequate documentation, missing clinical narratives that explain medical necessity, incorrectly billing D7311 alongside standalone alveoloplasty codes for the same treatment area, or failing to confirm coverage limits and frequency restrictions in advance. Prevention strategies include maintaining comprehensive clinical records, incorporating supporting radiographs or photographs, confirming patient benefits before treatment, and responding quickly with supplemental information when insurers request additional details.

What is the typical reimbursement range for D7311?

2026 Medicaid fee schedules give a public reference point for D7311: Medi-Cal Dental treats it as a global procedure with no separate fee (Medi-Cal Dental Schedule of Maximum Allowances, July 2026) and New York Medicaid pays $50.50 for patients 6 and older (New York Medicaid dental fee schedule, January 2026). D7311 is not a covered, separately priced service on the Florida Medicaid or Texas THSteps fee schedules. Commercial PPO reimbursement depends on the payer contract, your region and network status, so the most reliable number for your practice is the allowed amount on your recent EOBs for D7311.

Does D7311 require prior authorization?

Prior authorization requirements for D7311 depend on the patient's specific insurance plan. Some carriers require advance approval for procedures coded under D7311, while others process claims without it. Best practice is to verify authorization requirements during insurance eligibility checks before the appointment. If prior authorization is required, submit the request with detailed clinical notes and supporting documentation to avoid delays in patient care and claim processing.
