D7250 is the CDT code for the surgical removal of residual tooth roots using a cutting procedure — incising soft tissue, removing bone, taking out the retained root structure, and closing the site. It applies to roots left behind in the bone, not to a tooth still in place.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D7250 Code
Report D7250 when retained root tips or fragments remain in the alveolar bone — often from a prior fracture or a previous extraction — and a cutting procedure is needed to remove them: soft-tissue incision, bone removal, removal of the root, and closure. It describes a surgical retrieval of roots that are not simply exposed and graspable.
Code by what is being removed and how:
- If an erupted tooth or an exposed root is removed by simple elevation or forceps, that is D7140, not D7250.
- If a whole erupted tooth needs surgical access, that is D7210.
- D7250 is specifically for residual roots requiring a cutting procedure to retrieve.
A root that is fully exposed and lifted out without cutting generally does not meet the D7250 threshold.
Documentation & Clinical Scenarios
Because D7250 is a surgical retrieval, the documentation should show why cutting was required:
- Tooth number / site and the history (e.g., roots retained from a prior extraction or fracture).
- A radiograph demonstrating the residual root structure within the bone.
- An operative narrative documenting the cutting procedure — soft-tissue incision, bone removal, root retrieval, and closure.
- Any complications and sutures, noted clearly.
If the roots were exposed and removed without a cutting procedure, the simpler extraction code applies instead, and the note should reflect that.
Insurance & Billing Tips
- Verify benefits first. Confirm surgical extraction coverage, any waiting period, and the remaining annual maximum.
- Document the cutting procedure. D7250 is surgical; without a narrative showing soft-tissue and bone removal, payers may down-code it to a simple extraction.
- Attach the radiograph. A film showing the retained roots within bone is strong support.
- Bill add-ons separately. Sedation, grafts, and membranes are distinct codes, not part of D7250.
- Watch the timing. If roots are removed during the same visit as the original extraction, check payer bundling rules; a separate, later retrieval is more clearly its own service.
Example Case
A 60-year-old returns months after a molar broke off, reporting intermittent soreness in the area. A periapical radiograph shows two retained root tips of tooth #3 embedded in the alveolar bone. The dentist incises the soft tissue, removes overlying bone, retrieves both root fragments, and sutures the site — reported as D7250 with the radiograph and an operative narrative documenting the cutting procedure. Because the surgical retrieval was clearly documented and benefits verified, the claim is paid at the residual-root surgical level rather than as a simple extraction.

Frequently Asked Questions
What is the difference between D7250 and D7140?
The difference is whether a cutting procedure was needed. D7140 is a simple extraction of an erupted tooth or an exposed root removed by elevation or forceps — no surgical access. D7250 is the surgical removal of residual roots that requires incising soft tissue and removing bone to retrieve root structure left in the bone. If the root was exposed and lifted out without cutting, it is D7140; if soft tissue and bone had to be opened, it is D7250, supported by the operative note.
Can D7250 be billed at the same visit as the original extraction?
It can be situational. If retained roots are retrieved during the same appointment as the original extraction, some payers apply bundling rules, so the documentation should show that the residual-root removal was a distinct surgical effort. A retrieval performed at a later visit — for roots discovered or left behind previously — is more clearly its own service. Always check the specific payer's bundling policy and document the cutting procedure to support a separate D7250.
Does D7250 include X-rays, sedation, or bone grafts?
No. D7250 covers the surgical retrieval of the residual roots and closure. The diagnostic radiograph, any sedation, and any socket preservation graft or membrane are separate procedures with their own CDT codes. Reporting them on the extraction line causes bundling denials, so each is billed on its own line with its own supporting documentation.
Does D7250 require pre-authorization?
A pre-treatment estimate is not always required, but verifying benefits beforehand is recommended for any surgical procedure. Confirm surgical extraction coverage, any waiting period, and the remaining annual maximum, and submit the radiograph showing the retained roots when the payer expects it. Establishing the surgical nature of the retrieval up front reduces the chance of a denial or a down-code to a simple extraction.
