What documentation is required for D0150?
The CDT 2021 revision elevated oral cancer screening from "where indicated" to a mandatory, non-optional component of D0150. Every descriptor element below should be visible in the note — if the chart reads like a periodic exam, expect a downgrade.
- Medical and dental history — reviewed and updated, including medications, allergies, systemic conditions, ASA status, and risk factors (tobacco, alcohol, diabetes, HPV, immunosuppression). State what changed if anything; "no changes" is acceptable but should be written, not omitted.
- Chief complaint — in the patient's own words, even if the visit is a routine new-patient exam ("here for a check-up, no specific concerns" still counts).
- Vitals — BP and pulse where applicable. Some state boards and most sedation-capable practices require these on every comprehensive eval.
- Extraoral exam — head, neck, lymph nodes, TMJ (range of motion, clicking, deviation), masticatory muscles, skin.
- Intraoral soft tissue exam — lips, labial and buccal mucosa, tongue (dorsal, ventral, lateral borders), floor of mouth, hard and soft palate, oropharynx, gingiva.
- Oral cancer screening — explicitly documented as performed. Don't bury it inside "soft tissue WNL." Many auditors flag the absence of an explicit oral-cancer-screening line as a basis to downgrade.
- Hard tissue / dentition — caries, existing restorations and their integrity, missing or unerupted teeth, fractures, wear patterns, prostheses, abfraction.
- Periodontal screening or charting — at minimum a PSR or visual gingival assessment; full 6-point charting if indicated. The descriptor allows either; the choice between D0150 and D0180 turns on this point (see below).
- Occlusion — Angle classification, overjet/overbite, wear, parafunction, signs of bruxism.
- Radiograph review — note imaging interpreted today and any prior images consulted; radiographs are billed separately under D0210/D0220/D0270/D0274 etc. and are not bundled into D0150.
- Diagnoses — caries by tooth, perio status, occlusal/TMJ findings, mucosal findings. Be specific by tooth or area.
- Risk assessment — caries (low/moderate/high), periodontal, oral cancer.
- Treatment plan — sequenced, with options and the patient's choice noted; this is what makes the encounter "comprehensive."
- Provider signature and any auxiliary operator initials.
The standard "amnesia test" applies: a third party reading the note must be able to reconstruct the visit. Auto-populated default-normal findings (every tissue "WNL" for every patient on every visit) are a known audit pattern and a frequent cause of recoupment. Document what you actually observed.
Why does D0150 get denied?
The most frequent reasons D0150 is denied, downgraded, or recouped:
- Frequency violation — patient had any combined exam (D0120/D0140/D0150/D0180) within the carrier's lookback window. By far the most common cause of denial, and often the result of a prior provider's claim history the front desk can't see.
- Established patient with no significant change documented — carrier downgrades to D0120 because the note doesn't justify a fresh comprehensive. The phrase "patient returns for routine check-up" in the note is a self-inflicted downgrade.
- Insufficient documentation — missing extraoral exam, oral cancer screening, periodontal screening, or treatment plan. Auditors will downgrade if any descriptor element is silent in the note.
- Same-date conflict with another evaluation — D0150 billed alongside D0120, D0140, D0145, D0160, or D0180 on the same DOS. Only one evaluation pays per provider per day. D0150 + D0180 is the most common rejected pairing.
- D0150 billed routinely for recall visits — auditors flag offices whose D0150-to-D0120 ratio is elevated relative to specialty norms. The Texas OIG and several Medicaid MCOs have published audit findings citing exam-code overuse.
- Missing narrative when prior D0150 exists with another in-network provider — carriers see a duplicate and deny without a written explanation of significant change or 3-year absence.
- Default-normal templating — a note where every soft-tissue site is "WNL" with no patient-specific findings looks fabricated to a reviewer.
- No oral cancer screening line — post-2021, this is treated as a missing required element, not a missing optional one.
What do practices ask about D0150?
Can I bill D0150 every 6 months?+
Generally no. Most PPO carriers limit D0150 to once every 3 years per provider, and many Delta Dental plans allow it only once per provider per patient lifetime. Routine 6-month recall visits should be billed as D0120 (Periodic Oral Evaluation). MetLife's Federal Dental Plan is a notable exception in 2026 — it pools D0120/D0145/D0150/D0180 under a single "1 every 6 months" exam allowance, but the appropriate code still depends on the clinical scenario, and a patient won't legitimately have a new comprehensive every 6 months.
Is D0150 the same as a new patient exam?+
D0150 is what most offices call the new patient exam, but the ADA descriptor isn't exclusive to new patients. It also applies to established patients with a significant health change and to established patients absent from active treatment for 3+ years. The word "comprehensive" describes the scope of the evaluation (whole-mouth baseline plus treatment plan), not the patient's status.
Can I bill D0150 and D0180 on the same date?+
No. D0150 and D0180 describe overlapping evaluations and are mutually exclusive on the same date of service. Choose D0180 if the patient has signs or symptoms of periodontal disease, systemic risk factors (diabetes, smoking), or social risk factors, and you are performing full 6-point charting on every tooth. Otherwise choose D0150 — its descriptor allows periodontal screening or charting at your discretion.
Can I bill D0150 with an FMX, prophy, and bitewings on the same day?+
Yes. D0210 (FMX), D1110 (prophy), and bitewings are separate procedures and should be billed alongside D0150 when each is clinically performed and documented. ADA bundling guidance is explicit: radiographs are not bundled into the exam, and a same-day prophy is the norm for new-patient hygiene visits. One caveat — D0210 and D0274 typically aren't billed on the same date since the FMX subsumes bitewings; choose one based on what was actually exposed.
Does insurance always cover D0150?+
No. Coverage depends on the plan's frequency limits and whether the patient has had a D0150 with any provider in the carrier's recent claim history. If a previous dentist billed D0150 within the lookback window, the carrier may downgrade to a D0120 fee, deny entirely, or count the visit against the patient's annual exam allowance. Verifying "D0150 history" during eligibility is the single most effective way to avoid surprise denials.
Does D0150 require an oral cancer screening?+
Yes. Editorial revisions to the CDT 2021 descriptor made oral cancer screening a mandatory, non-optional component of D0150 (and D0120). The screening must be explicitly documented in the chart note — "soft tissue WNL" alone is no longer sufficient. Auditors increasingly cite the absence of an explicit oral-cancer-screening line as a basis to downgrade D0150 to D0120 or D0190.
If a patient transfers from another office that billed D0150 last year, can I bill D0150?+
Often no — most carriers track D0150 across providers within their plan-wide claim history and will deny or downgrade. Three workarounds, in order of strength: (1) document a significant health change since the prior D0150, (2) confirm the prior provider was out-of-network so the carrier's history doesn't reflect it, or (3) bill D0120 today and re-bill D0150 once the carrier's lookback window resets. Submitting a D0150 with a clear narrative still gets denied more often than not when the carrier's history shows a recent one.
