What documentation is required for D9310?
A defensible D9310 chart note has to make three things obvious to an auditor: (1) another practitioner requested the consult, (2) the consultant performed an evaluation including an oral exam and rendered an opinion, and (3) findings and recommendations were communicated back. Required elements:
- Identity of the referring provider — name, practice, and (when available) NPI of the dentist or physician who requested the consult. "Self-referred" or "patient walked in" disqualifies D9310.
- Reason for referral in the referring provider's words — what specific question is the consultant being asked? ("Evaluate #19 for possible RCT vs. extraction," "evaluate #1, #16, #17, #32 for surgical removal," "evaluate generalized recession and surgical candidacy," "evaluate ulcerated lesion left lateral tongue persisting >3 weeks.")
- Chief complaint and HPI — the patient's own description of the problem, onset, character, severity, prior treatment attempted. Even when the consult is provider-driven, the patient's narrative belongs in the chart.
- Medical history reviewed and updated — meds, allergies, anticoagulants, relevant systemic conditions. BP/vitals when treatment may follow.
- Oral evaluation — the descriptor explicitly states that the consultation includes an oral evaluation. Document extraoral, intraoral, and tooth/area-specific findings; do not skip this.
- Diagnostic tests and imaging interpreted — pulp tests, percussion, palpation, probing, mobility, transillumination as relevant. Imaging reviewed (referring provider's films, today's PA/pano/CBCT) interpreted in plain language tied to the diagnosis. Imaging is billed separately under its own CDT codes when captured by the consultant.
- Specific diagnosis and prognosis — name the condition and the tooth/area. "Symptomatic irreversible pulpitis #19, prognosis good with timely RCT," "full bony impaction #17 and #32 with high risk of pericoronitis," not "patient needs extraction."
- Treatment options and recommendations — what the consultant recommends, what alternatives exist, and the rationale. Include the option to defer and the consequences of doing so. This is the substance of the consult.
- Risks/benefits/alternatives discussed with the patient — informed-consent-grade narrative; document patient questions and the answers given.
- Plan and disposition — whether the consultant will perform the recommended treatment, the patient is being returned to the referring provider, or further workup is needed elsewhere.
- Written report back to the referring provider — this is the load-bearing element of D9310. Document that a consult letter, secure email, or EHR-shared note went to the referring provider, the date sent, and the method. Many carriers and audit programs ask to see the consult letter on review.
- Provider signature and credentials — consultant's name, specialty, and signature. State licensure of the consulting practitioner is what makes the encounter qualify as D9310 in the first place.
The two elements most often missing from denied D9310 claims are (1) the name of the referring provider and (2) evidence that a written report was sent back. Build both into the template so they cannot be skipped.
Why does D9310 get denied?
The most common reasons D9310 is denied, downgraded, or audited:
- No referring provider documented — chart shows the patient self-scheduled or "heard about Dr. X." Without a referring practitioner identified, the encounter cannot meet the D9310 definition and is recoded to D0140 or denied.
- No written consult report back to the referring provider — the load-bearing element of D9310. Carriers and Medicaid auditors will ask for the consult letter on review; absence of one is a common recoupment trigger.
- Billed by the treating dentist for their own patient — D9310 is for the consulting practitioner. The treating provider's problem-focused visit is D0140. This is the single most frequent miscode.
- Frequency exceeded under the combined evaluation cap — patient already used both periodic/comprehensive exams this benefit year, and the carrier pools D9310 with the rest.
- Same-day conflict with another evaluation code from the same provider — D9310 + D0150 or D9310 + D0140 by the same NPI on the same DOS is bundled or denied. Only one eval per provider per DOS pays.
- Specialty mismatch / out-of-network specialist — some plans only cover D9310 when the consultant is in a recognized specialty (endo, OMFS, perio, prostho, ortho, peds, oral medicine/pathology). PA-required plans often deny D9310 from a generalist consultant.
- Insufficient documentation of the consult question — chart note simply says "consult — recommend RCT" with no reason-for-referral, no HPI, no exam, no options discussion. Reads to an auditor like a brief check rather than a consultation.
- Used as a substitute for a comprehensive new-patient eval — specialist office bills D9310 on a new-patient referral but documents a routine new-patient comprehensive workup. Should be D0150 unless the visit was problem-focused on the referring provider's specific question.
- D9311 billed as a stand-alone with no underlying patient encounter — D9311 is for inter-provider consultation about a patient; it is not a stand-alone visit code and several carriers deny it without an associated encounter.
- No oral evaluation documented — descriptor explicitly requires that the consultation include an oral evaluation; chart notes that consist only of imaging review and recommendations are recoded.
- Missing provider signature or specialty credentials — auto-flagged by automated audits.
What do practices ask about D9310?
What's the difference between D9310 and D0140?+
The referral relationship. D0140 is the treating dentist's problem-focused evaluation of their own patient. D9310 is a different practitioner — typically a specialist — evaluating that patient on referral and reporting an opinion back to the requesting provider. The clinical workup may look identical (chief complaint, HPI, oral exam, imaging interpretation, diagnosis, recommendations); what makes it D9310 is that the consultant is answering a specific question posed by another practitioner who retains primary responsibility for the patient. If you're the patient's regular dentist seeing them for a toothache, that's D0140, not D9310 — even if the patient was originally referred to you by a physician.
Can a general dentist bill D9310?+
Yes, but only when acting as the consulting practitioner — for example, a GP with advanced training in oral medicine being asked by another GP to evaluate a soft-tissue lesion, or a GP asked by an orthodontist to opine on restorative implications of a planned tooth movement. Most carriers will pay D9310 from a generalist when the documentation supports a true consulting role (referring provider identified, specific consult question, written report back). Plans that restrict D9310 to recognized specialties will downgrade or deny generalist consultations.
Is a written consult letter required for D9310?+
Effectively yes. The ADA descriptor describes D9310 as a service in which the consultant's opinion or advice is requested by another practitioner — implying that the opinion is communicated back. Most carriers and Medicaid auditors will request the consult letter or shared EHR note on review, and absence of evidence that findings were communicated back to the referring provider is a common recoupment trigger. Build the report-back step into the workflow: secure email, signed PDF, or shared EHR note dated within a few days of the visit.
Can D9310 be billed on the same date as a procedure?+
Often yes, when the consultant initiates therapy at the same visit (e.g., evaluates a tooth and starts RCT the same day, or evaluates impactions and extracts the same day in a surgical office). The procedure is billed under its own code; D9310 is the cognitive consultative work. Carriers typically reimburse both when documentation shows the consultative evaluation was a separately identifiable service — meaning it goes beyond the pre-procedure check and includes the referring-provider context, options discussion, and report-back. Several carriers do bundle the consult into a same-day procedure when the chart doesn't make that distinction clear.
What's the difference between D9310 and D9311?+
D9310 is the consultant's encounter with the patient, including an oral evaluation. D9311 is the consultant's communication with another health care professional about the patient — typically a phone consultation or formal correspondence with a physician (oncologist, cardiologist, sleep medicine specialist, etc.) discussing a shared patient. They aren't substitutes; they cover different work products. Both can apply to the same overall episode of care if you both evaluated the patient and had a substantive provider-to-provider discussion.
Does a specialist seeing a new referred patient bill D9310 or D0150?+
Depends on scope. If the visit was tightly scoped to the referring provider's specific question — evaluate #19 for RCT, evaluate impactions, evaluate this lesion — D9310 is correct. If the specialist performed a comprehensive new-patient workup including full perio and dental charting, full radiographic review, and a multi-tooth treatment plan that goes beyond the referral question, D0150 is the better fit. Many specialty offices default to D0150 for the comprehensive new-patient visit and reserve D9310 for narrower consultative encounters where the question is clearly bounded.
Is prior authorization required for D9310?+
On commercial plans, usually no — the code pays as a routine evaluation when frequency allows. On Medicaid (state programs and MCOs like DentaQuest, Envolve, Liberty), prior authorization is common, often with a requirement to submit the referring provider's name and the consult question up front and the written consult report on or after the visit. Verify the specific plan's PA matrix before scheduling, especially for pediatric Medicaid.
