D7250 Dental Code: Residual Tooth Root Removal Billing Guide

What D7250 covers

D7250 reports the removal of residual tooth roots by a cutting procedure. Root fragments remain in the bone, usually left from a prior extraction or from trauma where the crown is already gone, and reaching them requires cutting soft tissue and bone. The procedure includes the flap, the bone removal, the removal of the root structure, and closure.

The defining facts are two: the crown is already gone, leaving only roots, and cutting is required to remove them. Both have to be true for D7250.

It does not cover:

• An erupted tooth or an exposed root removed by elevation or forceps without cutting. That is D7140, even when only a root is being removed.
• A whole tooth still bearing its crown. Those are the standard extraction or impaction codes.
• Coronal remnants of a primary tooth with resorbed roots. That is D7111.
• A difficult extraction of an otherwise standard tooth. D7250 is a different procedure category, not a difficulty modifier.

D7250 versus D7140

This is the line that matters most on the code. Both can involve roots, and the difference is access, not the fact that a root is being removed.

• D7140 covers an exposed root delivered by elevation and/or forceps, no cutting.
• D7250 covers residual roots that require cutting soft tissue and bone to reach and remove.

ADA guidance is clear that D7250 is not a code for a difficult extraction. If separated roots are exposed and can be elevated out, the correct code is D7140 even though it took effort. The shift to D7250 happens only when a cutting procedure was needed. The operative note has to record the cutting for the code to hold.

When to bill D7250

Bill D7250 when:

• Only root structure remains, with the crown already gone.
• Removing the roots required cutting soft tissue and bone.
• The roots are residual, typically from a prior extraction or trauma.

Do not bill D7250 for:

• An exposed root removed without cutting. Use D7140.
• A whole tooth with its crown present. Use the appropriate extraction or impaction code.
• A primary tooth coronal remnant with resorbed roots. Use D7111.
• A difficult but standard extraction. Use the code that matches the procedure, not D7250.

Top reasons D7250 gets denied or downgraded

1. Downgraded to D7140. The note didn’t establish that cutting was required, so the carrier paid at the simple-extraction allowable. The operative report recording the flap and bone removal is the defense.
2. Documentation missing. No radiograph showing the retained roots, no description of the cutting. The carrier cannot confirm the procedure.
3. Read as a difficult extraction. A note that describes a hard extraction of a whole tooth invites a downgrade because D7250 is not a difficulty code. The note has to establish residual roots and cutting.
4. Timing questions. When the residual roots are removed at the same visit as the original extraction, some plans scrutinize whether D7250 is separately reportable. This is plan-dependent.

Documentation that supports the claim

The claim is stronger with:

• A radiograph showing the retained root fragments in the bone.
• An operative note stating that only roots remained and that cutting soft tissue and bone was required.
• A description of the flap and the bone removal performed.

For the patient record, document:

• The tooth number and that only residual roots were present.
• The reason the roots required removal.
• The cutting procedure: the flap, the bone removed, and any sectioning.
• The origin of the residual roots when known (prior extraction, trauma).

The sentence that supports the code names the cutting: “Retained mesial and distal root fragments on tooth 30 from a prior extraction; mucoperiosteal flap elevated and buccal bone removed to access and section the roots for delivery.” That framing supports D7250 over a simple extraction.

Example case

A 47-year-old established patient has retained root fragments on tooth 19 from an extraction attempted elsewhere. The radiograph shows two root tips below the bone with no crown. The dentist elevates a flap, removes overlying bone, sections and delivers the roots, and closes.

Billing steps:

1. Take a radiograph showing the retained roots in the bone.
2. Code D7250 with an operative note recording the flap, the bone removal, and the cutting.
3. Attach the film to the claim.
4. Watch the EOB. If the carrier downgrades to D7140, appeal with the operative report documenting the cutting procedure.

What to get right in your PMS

1. Record the cutting in the operative note. D7250 turns on whether cutting was required; without that in the note, the carrier downgrades to D7140.
2. Confirm only roots remained. A whole tooth with its crown is a different code, regardless of difficulty.
3. Use D7140 when exposed roots come out without cutting. D7250 is not a reward for a hard case.
4. Attach the radiograph showing the retained roots. The film confirms the clinical picture and supports the allowable.
