D9110 is the CDT code for palliative (emergency) treatment of dental pain — the minor procedure done to relieve pain rather than to definitively treat its cause, reported per visit. It covers the focused effort to make a patient comfortable when they present in acute pain, not the eventual root canal, filling, or extraction that addresses the underlying problem.
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 D9110 Code
Report D9110 when a patient arrives in pain and the dentist performs a palliative, pain-relieving service — for example, opening and medicating a tooth, smoothing a sharp fractured edge, or placing a sedative dressing — without completing the definitive treatment that day. The code is procedure-based, billed per visit, and is meant for true emergency pain relief.
Don't confuse D9110 with the evaluation codes. A problem-focused exam is D0140 (limited oral evaluation), which can be reported alongside palliative care when both genuinely occur. D9110 is the treatment, not the exam, and it is not a placeholder for definitive care: when the dentist performs the root canal, filling, or extraction at the same visit, that procedure is coded on its own and D9110 is generally not separately billable.
Documentation & Clinical Scenarios
Because D9110 is an emergency, comfort-focused service, the record must show that pain relief — not definitive treatment — was the purpose of the visit:
- Tooth number (or area) and the diagnosis driving the pain (e.g., irreversible pulpitis, fractured cusp, symptomatic apical periodontitis).
- The palliative procedure performed — pulpal debridement, sedative filling, occlusal adjustment of a fractured edge, etc.
- A short narrative explaining that the visit was for emergency pain relief and that definitive treatment was deferred.
- Radiographs, when taken, billed under their own codes.
Anything definitive performed the same day is documented and billed separately. If a limited evaluation (D0140) was also done, it carries its own code; the chart should clearly separate the exam from the palliative treatment.
Insurance & Billing Tips
- Verify benefits and emergency coverage. Confirm that the plan covers palliative care and whether it counts against any frequency limits.
- Add a narrative. Many payers require a brief description showing the service was emergency pain relief, not part of definitive treatment.
- Watch for bundling. When definitive treatment is completed the same day, D9110 is often considered included in that procedure and may be denied if billed together.
- Pair the exam correctly. D9110 plus D0140 on the same date can be payable, but only with documentation supporting both a distinct evaluation and a distinct palliative procedure.
- Read the EOB. If a palliative claim is down-coded or denied, the narrative and any radiograph support a clean appeal.
Example Case
A patient calls Friday afternoon with a throbbing lower molar and swelling. The dentist performs a limited evaluation, takes a periapical radiograph, and diagnoses irreversible pulpitis on tooth #19. Because there isn't time to complete the root canal, the dentist opens the tooth, removes the inflamed pulp tissue, and places a sedative dressing to relieve the pain — reported as D9110, with the limited exam billed as D0140 and the radiograph on its own line. The definitive root canal is scheduled and coded the following week. Because the office documented the emergency, pain-relief purpose and billed each service separately, the claim processes cleanly.

Frequently Asked Questions
What's the difference between D9110 and a limited exam (D0140)?
They cover different things. D0140 is the problem-focused evaluation — the dentist examining the patient to figure out what's wrong. D9110 is the palliative treatment that follows to relieve the pain. On a true emergency visit both can occur and may both be reported, but the chart must clearly document a distinct exam and a distinct pain-relief procedure to support billing them on the same date.
What's included in D9110, and what's billed separately?
D9110 includes the minor, pain-relieving procedure itself — opening a tooth, a sedative dressing, smoothing a sharp edge. It does not include the definitive treatment (root canal, filling, extraction) or radiographs, which are each reported under their own codes. The point of D9110 is emergency comfort, with the real fix typically scheduled for a later visit.
How often will insurance cover D9110?
Coverage varies by plan. Many payers reimburse palliative treatment per emergency visit, but some apply frequency limits or require a narrative establishing that it was genuine emergency pain relief. Always verify the patient's benefits and whether palliative care counts against any annual maximum before assuming it will be paid.
Can D9110 be billed on the same day as the definitive treatment?
Usually not. If the dentist completes the root canal, filling, or extraction at the same visit, that definitive procedure is coded on its own, and D9110 is generally considered bundled into it. D9110 is intended for visits where pain is relieved but definitive care is deferred, so billing both for the same tooth on the same day commonly triggers a denial.
