Understanding Dental Code D7285

When to Use D7285 dental code

The D7285 dental code is designated for an incisional biopsy of oral tissue – hard (bone, tooth). This CDT code should be used when a dental provider needs to surgically remove a portion of hard oral tissue, such as bone or tooth, for diagnostic examination. Unlike excisional biopsies, which remove the entire lesion, an incisional biopsy under D7285 involves removing only a representative section for pathology. This code is appropriate when the clinical presentation suggests a need for further investigation of abnormal hard tissue, such as suspicious bony lesions, unexplained radiographic findings, or persistent swelling that cannot be diagnosed through less invasive means.

Documentation and Clinical Scenarios

Accurate documentation is essential for successful reimbursement when using D7285. Best practices include:

• Detailed clinical notes describing the lesion’s size, location, and characteristics.
• Radiographic evidence supporting the need for a biopsy (attach images to the claim if possible).
• Procedure description outlining the surgical approach, anesthesia used, and the portion of tissue removed.
• Pathology report (once available) to confirm the necessity and outcome of the biopsy.

Typical clinical scenarios for D7285 include evaluation of bony growths, suspected odontogenic tumors, or unexplained radiolucencies. If the biopsy involves only soft tissue, consider using the appropriate soft tissue biopsy code instead.

Insurance Billing Tips

To optimize claim acceptance and minimize denials for D7285, follow these insurance billing best practices:

• Verify patient benefits before the procedure to confirm coverage for surgical biopsies and pathology services.
• Submit comprehensive documentation with the claim, including clinical notes, radiographs, and the pathology report if available.
• Use accurate CDT coding and avoid upcoding or miscoding (do not use D7285 for excisional biopsies or soft tissue lesions).
• Appeal denied claims with additional supporting documentation, such as a letter of medical necessity from the provider and detailed clinical findings.
• Track claims in your AR system and follow up promptly on outstanding EOBs to ensure timely reimbursement.

Clear communication with both patients and payers about the medical necessity of the biopsy can also help reduce confusion and speed up claim processing.

Example Case for D7285

Case Scenario: A 45-year-old patient presents with a persistent, painless swelling in the posterior mandible. A panoramic radiograph reveals a radiolucent area suggestive of a possible odontogenic tumor. The provider documents the clinical findings, captures radiographic images, and performs an incisional biopsy of the affected bony area. The tissue sample is sent for pathology. The office submits a claim using D7285, including all supporting documentation. The insurance carrier requests the pathology report, which is provided upon receipt. The claim is approved, and payment is processed without delay.

This example illustrates the importance of thorough documentation, correct code selection, and proactive communication with both the patient and the insurance company when billing for D7285.
