CDT Code D7230: Removal of Impacted Tooth — Partially Bony

Reviewed by Dr. Morgan Heminger · Updated July 12, 2026

What Is D7230? (CDT Code Overview)

CDT code D7230 (Removal of Impacted Tooth — Partially Bony) is officially defined in the CDT as “removal of impacted tooth - partially bony.” It belongs to the Oral & Maxillofacial Surgery category of CDT codes (Surgical Extractions subcategory).

When Should You Use D7230?

The D7230 dental code applies to the extraction of impacted teeth that are partially covered by bone tissue. This code is designated for teeth requiring surgical removal due to partial bony impaction, making standard extraction methods insufficient. Dental offices typically apply D7230 for procedures involving teeth that cannot be removed through routine extraction techniques because of bone obstruction, commonly encountered with wisdom teeth. Selecting the appropriate code ensures proper payment processing and meets insurance documentation standards.

Quick reference: Use D7230 when the clinical scenario specifically matches partially bony impacted tooth extraction. Do not use this code as a substitute for related procedures in the same category. Consider whether D7210 (Surgical Extraction with Bone Removal) or D7220 (Partially Bony Impacted Tooth Extraction) might be more appropriate instead.

D7230 vs. Similar CDT Codes: Key Differences

Dental teams frequently confuse D7230 with other codes in the surgical extractions range. Here is how D7230 differs from the most commonly mixed-up codes:

Documentation Requirements for D7230

Supporting D7230 requires comprehensive record-keeping. Clinical documentation must clearly indicate the impaction classification (partial bony), identify the specific tooth, and outline the surgical procedure performed. X-ray images (including panoramic films) must be maintained in patient files to verify impaction severity. Typical applications for D7230 include:

• Third molars that have partially emerged with bone obstruction

• Impacted teeth creating discomfort, infection, or harm to neighboring teeth due to partial bone coverage

• Situations where routine extraction procedures (like D7140) cannot address the bone involvement

Maintain detailed records that demonstrate the procedure's complexity to prevent insurance rejections.

Documentation checklist for D7230:

• Patient chief complaint and relevant medical/dental history clearly recorded.

• Clinical findings that support the use of D7230 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 D7230.

• Post-procedure notes, including outcomes and follow-up recommendations.

Insurance and Billing Guide for D7230

Effective D7230 billing begins with thorough benefit verification and obtaining prior approval when necessary. Consider these guidelines:

• Check benefits: Verify whether the patient's insurance plan covers surgical tooth removal and recognizes D7230 as a covered service.

• Include supporting materials: Send clinical documentation and X-rays with your claim submission. Insurance companies frequently require this evidence to confirm treatment necessity.

• Write clear descriptions: In claim notes, explain why standard extraction methods were inadequate and describe the surgical technique used.

• Monitor claim responses: When claims are rejected, examine the insurance explanation carefully and prepare comprehensive appeals with additional supporting materials when appropriate.

These practices help minimize payment delays and increase approval success rates.

Common denial reasons for D7230: Lack of clinical documentation, frequency limitations exceeded, code mismatch with diagnosis, or missing prior authorization. When appealing a denied D7230 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.

Real-World Case Example: Billing D7230

A patient presents requiring a procedure consistent with D7230 (partially bony impacted tooth extraction). 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 D7230 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 D7230

Can code D7230 be applied to teeth beyond wisdom teeth?

Absolutely, although D7230 is frequently associated with third molars (wisdom teeth), this code can be utilized for any tooth presenting as partially bony impacted that necessitates equivalent surgical procedures. The determining factors are the clinical circumstances and degree of impaction rather than the particular tooth location. Always verify with the specific insurance carrier, as policies and coverage rules can vary significantly between payers. Maintaining thorough documentation for D7230 will strengthen your position in any audit or appeal scenario.

What are typical reasons insurance providers might reject D7230 claims?

Frequent denial reasons include inadequate documentation (missing X-rays or incomplete clinical records), insufficient clinical rationale for the extraction procedure, or failure to confirm coverage details and pre-authorization needs. Submitting comprehensive supporting documentation with claims helps prevent these complications. Always verify with the specific insurance carrier, as policies and coverage rules can vary significantly between payers. Maintaining thorough documentation for D7230 will strengthen your position in any audit or appeal scenario.

Is pre-authorization necessary for D7230 procedures with insurance carriers?

Pre-authorization policies differ among insurance providers. Certain insurers mandate pre-authorization for surgical extractions such as D7230, while others do not impose this requirement. The recommended approach is to confirm each patient's specific benefits and secure pre-authorization when necessary prior to treatment. Always verify with the specific insurance carrier, as policies and coverage rules can vary significantly between payers. Maintaining thorough documentation for D7230 will strengthen your position in any audit or appeal scenario.

What is the typical reimbursement range for D7230?

Reimbursement for D7230 (partially bony impacted tooth extraction) varies based on geographic location, payer contract terms, and whether the patient has in-network or out-of-network coverage. Fee schedules are typically set by individual insurance carriers, so practices should verify expected reimbursement during benefits verification. If your practice consistently receives lower-than-expected payments for D7230, consider renegotiating your fee schedule with major payers or reviewing your UCR (Usual, Customary, and Reasonable) data for your region.

Does D7230 require prior authorization?

Prior authorization requirements for D7230 depend on the patient's specific insurance plan. Some carriers require advance approval for procedures coded under D7230, 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.
