Understanding Dental Code D2955

When to Use D2955 dental code

The D2955 dental code is used for the removal of a dental post from a tooth. Posts are often placed within the root canal of a tooth to help retain a core buildup or crown. Over time, situations may arise where the post must be removed—such as retreatment of a root canal, failure of the restoration, or preparation for a new prosthesis. It’s critical to use D2955 only when the procedure involves the actual removal of a post, not for the removal of pins, screws, or other restorative materials. Proper code selection ensures accurate claim submission and reduces the risk of denials.

Documentation and Clinical Scenarios

Accurate documentation is essential when billing D2955. The clinical notes should clearly state:

• The reason for post removal (e.g., retreatment, restoration failure, or prosthetic replacement)
• The type and location of the post
• Any complications encountered during the procedure
• Steps taken to remove the post and the outcome

Common clinical scenarios include:

• A patient requires endodontic retreatment due to persistent infection, necessitating post removal.
• A fractured post must be removed to allow for a new core buildup and crown.
• Preparation for a new prosthesis where the existing post is no longer viable.

Always ensure that the documentation supports the necessity and complexity of the procedure to justify the use of D2955.

Insurance Billing Tips

To maximize reimbursement and minimize claim denials when billing D2955, follow these best practices:

• Verify coverage: Not all dental plans cover post removal as a separate procedure. Check the patient’s benefits before treatment.
• Submit detailed narratives: Include a concise narrative explaining why the post removal is necessary, referencing clinical findings and radiographs if available.
• Attach supporting documentation: Radiographs, intraoral photos, and chart notes can substantiate the claim and reduce the likelihood of a request for additional information.
• Use correct CDT codes: Only use D2955 for post removal. If additional procedures are performed, such as core buildup (D2950), bill them separately with appropriate documentation.
• Track EOBs and AR: Review Explanation of Benefits (EOBs) promptly and follow up on Accounts Receivable (AR) to address any denials or underpayments. Be prepared to submit claim appeals with additional documentation if needed.

Example Case for D2955

Case: A patient presents with a previously treated tooth exhibiting symptoms of infection. Radiographs reveal a post in the canal, and the dentist determines that endodontic retreatment is necessary. The post is carefully removed using ultrasonic techniques, and the canal is retreated. The clinical notes document the rationale for post removal, the technique used, and the outcome. The claim is submitted with code D2955, a detailed narrative, and supporting radiographs. The insurance carrier processes the claim without delay, and payment is received according to the patient’s plan benefits.

This example highlights the importance of thorough documentation, proper code selection, and proactive insurance communication when billing for D2955.
