D7111 is the CDT code for removing the remaining crown of a primary (baby) tooth when the roots have already resorbed or are gone — a narrow pediatric code, distinct from D7140, which covers a primary tooth that still has roots.
It is a pediatric code, and it is narrow: there are no roots left to deliver, just the remaining crown structure. Billing it comes down to two recurring snags: confusion with D7140 (which covers a primary tooth that still has roots), and carriers that question whether a remnant extraction was a billable procedure at all.
What D7111 covers
D7111 reports the removal of the coronal remnants of a primary tooth. The crown, or what is left of it, is the only structure remaining. The roots have already resorbed during the natural exfoliation process, or they are otherwise gone. The procedure removes that retained coronal structure.
This is a pediatric code. It exists for the situation where a baby tooth has shed its roots but the crown has not come out on its own, often because decay has broken down the crown or normal exfoliation stalled.
It does not cover:
- A primary tooth that still has roots. Removing a rooted primary tooth by elevation or forceps is D7140.
- A permanent tooth in any form.
- Residual roots of a permanent tooth that require cutting to remove. That is D7250.
- A surgical extraction requiring a flap, bone removal, or sectioning. Those are the D7210 and impaction codes.
The defining fact is the absence of root structure on a primary tooth. If roots are present, D7111 is the wrong code.
When to bill D7111
Bill D7111 when:
- The tooth is primary (a baby tooth).
- Only the crown, or a coronal remnant of it, remains.
- The roots have resorbed or are otherwise absent.
- Instrumentation was needed to remove the remnant.
Do not bill D7111 for:
- A primary tooth with roots still present. Use D7140.
- A permanent tooth. Use the appropriate permanent-tooth extraction code.
- A residual permanent root requiring a cutting procedure. Use D7250.
D7111 versus D7140
These two codes both apply to baby teeth, and the line between them is the single most common source of error on this code. The distinction is root structure.
- D7111 is the coronal remnant. No roots remain. The procedure removes the leftover crown.
- D7140 is the extraction of a primary tooth that still has roots, delivered by elevation and/or forceps.
A carrier reviewing a D7111 claim is checking the same thing: was there really no root, or was this a routine primary extraction that should have been D7140? The radiograph and the note settle it. If the film shows resorbed or absent roots and the note says only coronal structure was present, D7111 holds.
Top reasons D7111 gets denied or downgraded
- Reclassified to D7140. The carrier reads the case as an ordinary primary-tooth extraction and pays at the D7140 allowable. The defense is documentation that root structure was absent.
- Questioned as not separately billable. Some plans treat removal of a loose, near-exfoliating remnant as not a distinct procedure. This is plan language. A note describing the instrumentation required helps.
- Documentation missing. No radiograph, no description of what remained. The carrier cannot confirm the code without it.
- Tooth number outside the primary range. A permanent tooth number on a D7111 line draws an automatic denial. The code is primary-only.
Documentation that supports the claim
The claim is stronger with:
- A radiograph showing absent or fully resorbed roots on the tooth.
- A note stating that only coronal structure remained.
- A short description of how the remnant was removed.
For the patient record, document:
- The tooth number and that it is primary.
- The condition of the crown (decay, fracture, retained after partial exfoliation).
- The absence of root structure.
- The instrument or technique used to remove the remnant.
The sentence that does the work names the absence of roots: “Tooth K presented as a retained coronal remnant with no remaining root structure on the radiograph; the crown was elevated and removed.” That framing supports D7111 over D7140.
Example case
A 7-year-old established patient has tooth A, a primary second molar, with a grossly decayed crown that has not exfoliated. The radiograph shows the roots have fully resorbed and only the coronal structure remains. The dentist removes the remnant.
Billing steps:
- Take a pre-op radiograph showing the absence of roots.
- Code D7111 with the tooth number and a note describing the coronal-only remnant.
- Attach the film to the claim.
- Watch the EOB. If the carrier downgrades to D7140, appeal with the radiograph and the note documenting absent root structure.
What to get right in your PMS
- Confirm the tooth is primary before using D7111. A permanent tooth number triggers an automatic denial.
- Attach the radiograph to the claim. The film showing absent roots is the difference between D7111 and a D7140 downgrade.
- Write the note at treatment time. Describe that only coronal structure remained, not just that an extraction occurred.
- Use D7140 when roots are present. A rooted primary tooth is D7140, even if the crown is mostly destroyed.
FAQs
- What's the difference between D7111 and D7140 on a baby tooth?
- D7111 is for a primary tooth where only the crown remains and the roots have already resorbed or are gone. There is nothing to deliver but the coronal structure. D7140 covers a primary tooth that still has roots, removed by elevation or forceps. If roots are present and have to come out, the code is D7140, not D7111. The distinction is whether root structure remained at the time of the procedure.
- Does D7111 only apply to primary teeth?
- Yes. D7111 is specific to primary (baby) teeth. A retained root tip or coronal fragment on a permanent tooth is coded differently. If a permanent tooth has residual roots that require cutting to remove, that is D7250. D7111 is a pediatric code by definition.
- Why did the carrier deny or downgrade my D7111 claim?
- Two common reasons. First, the carrier read the case as a routine primary-tooth extraction and reclassified it to D7140. Second, some plans question whether removing a near-exfoliating remnant is a separately billable service. A note describing that only coronal structure remained, with no root present, and that instrumentation was needed to remove it, is the defense. This is plan-dependent.
- Do I need an X-ray for D7111?
- Most carriers want one, and it helps the claim regardless. A radiograph showing the absence of root structure supports the choice of D7111 over D7140 and confirms the clinical picture. Attach it with the initial claim rather than waiting for a request. Plan requirements vary.
- Can D7111 be billed per tooth on the same date?
- Yes. D7111 reports one tooth. Each remnant removed gets its own claim line with its own tooth number. There is no code-level limit on the number of lines per visit, though some plans cap the number of extractions paid per day under the benefit design. That is a benefit cap, not a coding restriction.
