What documentation is required for D7287?
Whichever descriptor your payer is on, the documentation principle is the same: a third-party reviewer must be able to reconstruct the lesion, the technique, the specimen handling, and the follow-up plan from the chart note alone. For current-CDT D7287 (exfoliative cytology), the note should make the cell-collection nature of the procedure unmistakable.
- Medical history reviewed/updated — meds, anticoagulants (matters less for cytology than for incisional/excisional, but still document), allergies, immunosuppression, prior head/neck radiation, smoking/alcohol/HPV risk factors. Risk factors justify the workup.
- Vitals — BP and pulse at minimum on any in-office surgical or sampling encounter.
- Site / anatomic location — exact mucosal site (left lateral tongue, right buccal mucosa at occlusal plane, floor of mouth midline, etc.). Side and landmark, not just "tongue."
- Lesion description — color, border definition, surface texture (smooth, verrucous, granular, ulcerated), induration, fixation, symptoms (pain, paresthesia, bleeding). Objective findings, not conclusions.
- Size — measured in mm (length x width, depth/induration if assessable). "Small" is not a measurement.
- Duration — how long the lesion has been present per the patient and any change over time. Persistent >14 days raises the index of suspicion enough to justify sampling.
- Pre-op clinical photograph — strongly recommended; some payers and most malpractice carriers expect it. Note that a photo was captured and stored in the chart.
- Differential diagnosis — the lesions you are trying to rule in or out (e.g., "rule out dysplasia vs. frictional keratosis"). Establishes medical necessity for sending a specimen to a lab.
- Consent / PARQ — procedure, alternatives (including biopsy with histopathology, watchful waiting with photo-documented re-evaluation in 2 weeks, referral to OMFS or oral medicine), risks (bleeding, non-diagnostic specimen, sampling error, need for definitive biopsy), and questions answered. Document signed or verbal consent.
- Anesthesia, if any — most exfoliative cytology requires no anesthesia; if topical or local was used, document agent, concentration, and carpules. Don't auto-populate anesthesia lines you didn't actually deliver.
- Sampling technique — explicitly: "exfoliative cytology specimen obtained by [scrape with #15 blade / cytobrush / swab / spatula] from the lesion surface." This sentence is what differentiates D7287 from D7286/D7288 in the chart.
- Specimen handling — slide(s) prepared, fixative used (95% alcohol spray, alcohol jar, or liquid-based cytology medium per the lab), labeling with patient identifiers, and chain-of-custody. Cytology specimens are not placed in formalin — formalin denatures cytologic stains.
- Pathology lab — receiving lab name, requisition number, and the specific cytologic interpretation requested (e.g., "exfoliative cytology, rule out dysplasia").
- Complications — bleeding, patient tolerance, syncope, vasovagal — or "none."
- Post-op instructions — typically minimal for cytology (no rinsing for 30 minutes if applicable, watch for unexpected bleeding, call with concerns).
- Result-disclosure plan — when and how the patient will be informed of the cytology result, and the contingency if the result is positive, atypical, or non-diagnostic. A "non-diagnostic" or "atypical" cytology almost always requires definitive incisional/excisional biopsy (D7286/D7285), and the chart should anticipate that escalation.
- Next visit / follow-up — concrete date for results review or definitive biopsy referral. A cytology specimen lost to follow-up is the most common audit/malpractice exposure on this code.
The chart-note "amnesia test" is especially important for sampling codes: if a reviewer can't tell from the note whether you brushed the surface (D7287), brushed through the full epithelium (D7288), or removed a piece of tissue (D7286), the carrier will pick the cheapest interpretation, and a plaintiff will pick the most damaging.
Why does D7287 get denied?
Common denial, downgrade, and audit triggers for D7287:
- Code-descriptor mismatch in the chart — note describes margins, sutures, formalin, or "lesion excised," but billed as D7287. Reviewer recodes to D7286 (often at a lower allowable than the office expected) or denies for "service not consistent with documented procedure." This is the most common denial pattern post-2023.
- D7287 billed when D7288 was performed — true transepithelial brush biopsies (OralCDx BrushTest) belong to D7288. Carriers that recognize the brand pathway will deny D7287 if the supply log shows a D7288-specific brush kit.
- Billed alongside D7286/D7285 on the same lesion — bundled by most carriers as inclusive; only the definitive biopsy pays. Document separate sites if both are clinically warranted.
- Missing pathology lab destination — note doesn't name the receiving lab or include a requisition number. Carriers and auditors read this as a sample never sent.
- No clinical photo or measurement — payers that require image documentation for biopsy/cytology codes will deny without it. AAOMS and most malpractice carriers consider a pre-op photo standard of care.
- Default-normal lesion description — copy-paste "white plaque, asymptomatic" with no measurements, borders, or duration on every cytology code looks fabricated.
- Result not reconciled in chart — the cytology was sent but no pathology report is filed, no patient was notified, and no follow-up was scheduled. This is the highest-malpractice-exposure failure mode for this code, and OIG audits in several states have cited "specimen sent without follow-up" as a quality-of-care finding.
- Medicaid non-covered — many state Medicaid plans simply don't cover exfoliative cytology codes; denial is for benefit, not documentation.
- Frequency / repeat sampling — repeat D7287 on the same lesion without escalation to definitive biopsy is denied as not medically necessary in most carrier clinical policies.
- Submitted without diagnosis code (medical cross) — when cross-coding to medical, missing or non-specific ICD-10 (e.g., K13.79 unspecified instead of K13.21 leukoplakia) triggers automated medical denials.
What do practices ask about D7287?
Is D7287 still 'biopsy excisional'?+
No. The CDT 2023 revision retired the older 'excisional biopsy' meaning of D7287 and redefined the code as 'exfoliative cytological sample collection' — surface cell collection sent for cytologic interpretation, not surgical removal of tissue. The current descriptor has carried into CDT 2024, 2025, and 2026. Many EHR libraries, third-party fee schedules, and chart-note templates (including the body that ships with this template) still describe D7287 as an excisional biopsy; that language is out of date. Confirm against your office's current CDT codebook before billing, and if you removed tissue with margins, code D7286 (soft) or D7285 (hard) instead.
What's the difference between D7287 and D7288?+
Depth of sampling. D7287 is non-transepithelial — a scrape, swab, or simple brush of the lesion surface that collects exfoliated superficial cells (think oral Pap smear). D7288 is transepithelial — a stiff brush designed to penetrate the full epithelial thickness and capture basal-layer cells, where dysplastic change originates. The OralCDx BrushTest is the canonical D7288 product. Diagnostically D7288 has higher sensitivity for dysplasia; D7287 is more useful for confirming candidiasis, viral cytopathic effect, or grossly atypical surface cytology.
Can I bill D7287 and D7286 on the same lesion same day?+
Generally no. Most carriers consider exfoliative cytology inclusive when a definitive biopsy of the same lesion is performed at the same visit; only the biopsy pays. If you sample one lesion with cytology and biopsy a separate lesion at a different anatomic site on the same date, document both lesions distinctly and most carriers will pay both, but expect to attach a brief narrative.
Does the specimen go in formalin?+
No — that's the most common documentation error on D7287. Cytology specimens are fixed on slides with alcohol spray (or in alcohol jars or liquid-based cytology medium per the receiving lab's protocol). Formalin denatures the cytologic stains used in cytopathology and is appropriate for histopathologic biopsy specimens (D7286/D7285), not for D7287. If your chart note says 'specimen placed in formalin,' the chart describes a biopsy, not a cytology.
Does insurance cover D7287?+
Coverage is plan-specific. Most commercial dental PPOs cover D7287 when documentation supports clinical necessity (suspicious lesion, defined risk factors). Many state Medicaid programs do not list D7287 as a covered adult dental benefit. Medical plans often cover oral cytology under cytopathology CPT codes (88160-88162) when cross-coded with appropriate ICD-10 (K13.21 leukoplakia, R68.81 oral mass, D37.09 neoplasm of uncertain behavior). The pathology lab bills its interpretation separately from the office's collection fee — make sure the patient knows this.
What if the cytology comes back atypical or non-diagnostic?+
Escalate to definitive incisional biopsy (D7286 for soft tissue, D7285 for hard tissue) or refer to oral surgery / oral medicine. Exfoliative cytology is a screening-tier test, and a non-diagnostic or atypical result on a clinically suspicious lesion is not reassurance — it's an indication for tissue biopsy. The chart should anticipate this escalation in the result-disclosure plan documented at the time of sampling.
Do I need a clinical photograph?+
It's not formally required by every carrier, but a pre-op intraoral photo with a millimeter ruler is considered standard of care for any oral lesion sampling and is expected by most malpractice carriers. Several payer clinical policies for biopsy and cytology codes ask for image documentation when adjudicating high-dollar or repeat-sampling claims.
