The short version
# D9110 Dental Code: Palliative Treatment for Dental Pain
D9110 is the CDT code for a visit in which the dentist relieves dental pain with treatment that isn't curative and has no more specific procedure code. The evaluation and the pain-relieving service are separate work, so D0140 and D9110 can both be reported when both occur. The claim fails when the note only says “emergency visit” or when another code describes the treatment.
- Bill D9110 per visit when the dentist performs a pain-relieving procedure that doesn't cure the condition and doesn't have its own CDT code.
- D0140 is the focused evaluation that identifies the problem. D9110 is the treatment that provides temporary relief. The ADA says both can be reported on one date when both distinct services occur.
- Don't use D9110 when D2940, an incision-and-drainage code, gingival irrigation, or another specific procedure describes the treatment.
- Payer rules can limit same-day payment even when the codes correctly report two services. Ask about the code combination when the plan is unfamiliar.
- In a worked example, a $125 office fee becomes an $85 allowable. At 80%, the plan pays $68, the patient owes $17, and the office adjusts $40.
- Document the pain, diagnosis, exact relief provided, why no specific code fit, the patient's response, and the definitive next step.
What is D9110?
D9110 reports temporary relief of dental pain when the actual procedure has no distinct CDT code. The dentist decides what treatment is appropriate for the patient's pain.
| Fact | D9110 |
|---|---|
| CDT category | Adjunctive general services |
| Unit | Per visit |
| Purpose | Relieve pain without curing the underlying condition |
| Code-selection rule | Use only when no specific procedure code describes the treatment |
| Can accompany | A separately performed D0140 evaluation, subject to plan benefits |
| Public fee reference | Washington Medicaid listed $51.25 for adults and $62.10 for patients under 21, effective July 1, 2025 |
The ADA's D9110 guide uses food-entrapment irrigation for pain relief as one example when no specific procedure code applies.
When do you bill D9110?
Bill D9110 after the dentist provides a real pain-relieving intervention and confirms that no other CDT code describes it.
- The patient has dental or oral pain that requires treatment during the visit.
- The service provides relief but doesn't complete definitive treatment of the cause.
- The dentist can describe exactly what was done beyond the evaluation.
- No restorative, endodontic, periodontal, surgical, or other procedure code fits the service.
- The record includes the follow-up or definitive treatment plan.
The appointment label doesn't decide the code. An emergency evaluation without treatment supports the evaluation code only. Definitive treatment, such as an extraction or restoration, uses that procedure code. D9110 fills the narrow space where the dentist performed temporary relief that has no better code.
D9110 vs D0140 and D2940
Separate diagnosis from treatment, then select the most specific treatment code available.
| D0140 focused evaluation | D9110 | D2940 or another specific code | |
|---|---|---|---|
| What happened | Dentist evaluated a defined problem | Dentist performed otherwise uncoded temporary pain relief | Dentist delivered a procedure with its own code |
| Main result | Diagnosis or next step | Relief without cure | Named interim or definitive treatment |
| Unit | Per evaluation | Per visit | Depends on the procedure |
| Same-day reporting | Can accompany distinct treatment | Can accompany D0140 when both occurred | Evaluation may also report when separately performed |
The ADA says temporary restorative material can be D2940 when it protects the tooth or tissues and the patient will return for evaluation and definitive care. D9110 isn't the substitute because a specific restoration code exists. The same reasoning applies to incision and drainage or medicinal gingival irrigation.
The expensive mistake is billing D9110 on top of every urgent procedure. If an extraction relieved the pain, the extraction code describes the treatment.
What does insurance actually do with D9110?
The ADA permits reporting D0140 and D9110 together when the dentist performs both the focused evaluation and a distinct palliative treatment. The ADA guide also warns that plans can exclude or limit payment for same-day combinations. The code doesn't require a narrative. The ADA recommends keeping enough detail to supply one when a payer asks.
- Office fee: $125
- Contracted allowable: $85
- Contractual adjustment: $40
- Plan payment at 80%: $68
- Patient coinsurance: $17
Why does D9110 get denied?
- The note describes only an evaluation, prescription, or discussion and no pain-relieving procedure.
- A more specific code, such as D2940, D7510, or D4921, describes the service.
- D9110 is billed with definitive treatment and the payer treats it as included.
- The narrative doesn't explain what the dentist did or why the treatment was palliative.
- The plan excludes the D0140-and-D9110 combination or applies another same-day limit.
Match the appeal to the denial. If another code truly fits, correct the claim.
What documentation gets D9110 paid?
- Record the pain location, onset, severity, and relevant symptoms.
- State the focused examination findings, tests, diagnosis, and tooth or tissue involved.
- Describe every step of the pain-relieving treatment.
- Explain why no more specific procedure code described that treatment.
- Record the patient's response and any medication instructions.
- State the definitive care, referral, or return visit planned.
Common questions about D9110
Is prescribing an antibiotic enough to bill D9110?
The ADA guide frames D9110 as a pain-relieving treatment, not a label for every urgent visit. A prescription by itself doesn't show a distinct procedure in the mouth. Report the evaluation performed and document the medication. Use D9110 only when the dentist also delivered an otherwise uncoded palliative procedure.
Can D9110 be billed with D0140 on the same day?
Yes, when the dentist completed both a focused evaluation and a separate palliative treatment. The ADA expressly allows both to be reported. A benefit plan may still pay only one line, so verify the contract and give the patient an estimate before the visit when possible.
Can D9110 be used for a periodontal abscess?
It can apply only when no specific procedure code fits what the dentist did. The ADA guide says drainage through an incision can point to D7510 and medicinal pocket irrigation can point to D4921. If neither describes the actual relief provided, document the service and consider D9110.
Is D9110 an emergency exam code?
No. D9110 reports otherwise uncoded treatment that relieves pain. D0140 reports the problem-focused evaluation, and an after-hours office visit can involve another code under its own rules. Calling the appointment an emergency doesn't replace the need to identify, document, and code each service performed.
Read one urgent note before billing
Don't choose D9110 until you've confirmed that no more specific procedure describes the relief provided. If another code fits, don't use D9110.
